BACKGROUND OF THE INVENTION

This application relates generally to the provision of urgent public information, and specifically to methods and systems for distributing urgent public information.

Often, urgent public information is of a critical nature, such that it would be beneficial to have some reliable means to make reasonably sure that the information reaches the intended audience it should be disseminated to the interested segment of the population. As well, urgent public information, by its nature, sometimes is time-sensitive, such that it is desirable the information be disseminated to the interested population as expeditiously as possible.

Existing alert distribution systems generally rely on a blanket method of distribution, using broadcast media (e.g., television and radio stations) to inform the public of urgent information. Such distribution systems are overbroad, in that each person watching television or listening to the radio in a given broadcast area is subjected to repeated broadcast of the information whether or not it even applies to or is of interest to that person. The systems are also underinclusive, however, in that certain people, to whom the alerts may be of vital interest, likely will not receive the alert if they are not either watching television or listening to the radio.

There is a need for a new distribution system, therefore, that allows for more timely and/or selective distribution of urgent public information to those to whom the information likely would be of interest.

BRIEF SUMMARY OF THE INVENTION

The invention therefore seeks to solve certain deficiencies in the prior art. Embodiments of the invention provide systems and methods for distributing urgent public information. For example, one exemplary of the invention provides a method for providing an alert to a subscriber. The exemplary method comprises receiving an alert message from at least one alert source. The alert message often will be pertinent to at least one of the subscribers. The alert message can comprise an alert and associated alert information. The alert information can provide information about the alert such that the information can be analyzed determine whether a particular subscriber likely should receive the alert.

The message can further include selecting, based on the nature of the alert and/or the alert information, a set of one or more distribution addresses to which the alert pertains and transmitting the alert to an alert gateway associated with one of the set of distribution addresses. In some cases, the alert can comprise urgent public information. In particular, and merely by way of example, the urgent public information can include an Emergency Alert System transmission, an Amber Alert transmission, a severe weather notification, and a Homeland Security Advisory notification. In certain embodiments, the alert information is incorporated within the alert itself while, in other cases, the alert information is additional to the alert. Thus, the method can further comprise extracting the alert information from the alert message. In another embodiment, the method can comprise analyzing the alert information to determine the set of one or more distribution addresses to which the alert pertains. In accordance with some embodiments, transmitting the alert to the alert gateway can comprise transmitting the alert message to the alert gateway.

Optionally, the method can include anticipating a confirmation message from the alert gateway, and, if no confirmation message is received within a certain time interval, retransmitting the alert. In some cases, transmitting the alert comprises transmitting the alert via a first path and retransmitting the alert comprises transmitting the alert via a second path. In other cases, retransmitting the alert can comprise transmitting the alert a second time via the same path.

In accordance with some embodiments, the alert can be processed. Merely by way of example, the alert can comprise audio and/or video information, and processing the alert can comprise translating the audio information into textual information and/or extracting closed-captioning information from a video signal. In another example, the alert can comprise text, and processing the alert can comprise converting the text into audio information. In some cases, the alert may be encoded and processing the alert can comprise decoding the alert. For instance, the alert can be encoded with event and/or location information (e.g, such information as required for conformance to the Emergency Alert System standards, a list of ZIP codes and/or area codes affected, information about the type of alert, and the like) and processing the alert can comprise interpreting the event and/or location information.

In accordance with some embodiments, the alert can be received at an alert gateway and a specific action can be taken in response to the alert. Merely by way of example, the specific action can include informing a subscriber about the alert by playing an audible signal, displaying a visual alert signal and/or transmitting the alert to at least one subscriber device. In some cases, the subscriber device can include a set of features associated with it and the method can further comprise processing the alert according to the set of features associated with the subscriber device prior to sending the alert to the subscriber device. In other cases, the subscriber device can be a plurality of subscriber devices. Merely by way of example, subscriber devices can include wireless telephones, POTS telephones, IP telephones, personal computers, handheld computers, televisions, set-top boxes, pagers, and the like.

In some cases, the at least one specific action can include anticipating a confirmation message from the subscriber device, and/or if no confirmation is received from the subscriber device within a certain time interval, the method can comprise retransmitting the alert, either to the same subscriber device or to one or more additional subscriber devices. In some cases, if no confirmation message is received from the subscriber device within a certain time interval, a failure message can be transmitted from the gateway to the alert distribution device.

Other embodiments of the invention include systems for providing alerts to appropriate subscribers. In accordance with some embodiments, these systems can perform the methods described above. One exemplary system can be used in a relationship between an information provider and a plurality of subscribers. Each subscriber generally can be associated with an alert gateway, with corresponding to a distribution address. The system therefore can provide an alert to a subscriber and can comprise an alert receiver and an alert distribution device, as well as an alert gateway. The alert receiver can be configured to receive an alert message from at least one alert source. The alert message can be pertinent to at least one of the subscribers and can comprise an alert and/or associated alert information. The alert information can provide information about the alert such that the alert information may be analyzed to determine whether a particular subscriber likely should receive the alert.

The alert distribution device can be in communication with the alert receiver and can be further in communication with the communication network. The alert distribution device can be configured to select, based on the alert information, a set of one or more distribution addresses to which the alert applies and transmit the alert to the selected set of distribution addresses via the communication network. The alert gateway can also be in communication with the communication network and can be associated with one of the distribution addresses. The alert gateway can be configured to receive the alert from the alert distribution device and to take at least one specific action with respect to the alert. The alert gateway can be incorporated within a network interface device and/or can be in communication with the network interface device.

The communication network can comprise, merely by way of an example, a radio-frequency transmission, a telephone network, a cable television distribution network, the Internet, a fiber-optic network, a high-speed data network, a wireless network, a microwave network, and the like. In some cases, a communication network can be a plurality of communication networks and, for a particular distribution address, the alert distribution device can be configured to select the most appropriate communication network via which to transmit the alert information to the particular distribution address.

In some cases, the alert gateway can be configured to transmit a confirmation message to the alert distribution device, a confirmation indicating that the alert was received by the alert gateway. Optionally, the confirmation message can be transmitted via the communication network. In some cases, the alert distribution device can be configured to retransmit the alert to the distribution address associated with the alert gateway in the event that a confirmation message has not been received from the alert gateway within a certain period of time. Thus, in some cases, the alert gateway and the distribution device can be in communication via more than one communication network and if the alert is transmitted via a first communication network, and no confirmation message is received, the alert distribution device can be configured to select a second communication network for retransmission of the alert.

In accordance with certain embodiments of the invention, the system can further comprised an alert processing device, which can be in communication with the alert distribution device and/or the alert gateway. The alert processing device can be configured to process the alert. Merely by way of example, the alert processing device can be a computer (such as any discussed below) which can include software or firmware executable by the alert processing device to process the alert. In some cases, the alert receiver can incorporate the functionality of the alert processing device. In other cases, the alert gateway and/or the alert distribution device can incorporate the functionality of the alert processing device. Other embodiments can further comprise an alert notification device coupled to the alert gateway. The alert gateway can be configured to activate the alert notification device to inform the subscriber about the alert.

In still further embodiments, the alert distribution device can be in communication with a storage medium, and the storage medium can be configured to store selection criteria associated with each of the plurality of distribution addresses. The alert distribution device then can be configured to select at least one distribution address to which the alert applies based on a correlation between the alert information and a selection criterion for the at least one distribution address. The selection criterion can be selected from a group consisting of the subscriber's geographic location, a subscriber's personal information, a subscriber's entertainment preferences, a subscriber's school location, and a subscriber's financial information.

In accordance with particular embodiments, the alert distribution device comprises at least one interface, which can be in communication with an alert receiver and/or a communication network. The alert distribution device can further comprise a processor and/or storage medium in communication with the processor. The storage medium can include instructions executable by the processor to receive an alert message to select, based on alert information included with the alert message, a set of one or more distribution addresses to which the alert applies, and to transmit the alert to the selected set of distribution addresses.

DETAILED DESCRIPTION OF THE INVENTION

Various detailed embodiments of the present invention are disclosed herein; it should be understood, however, that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein should not be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art variously to employ the present invention in virtually any appropriately detailed structure.

Embodiments of the invention provide, among other things, systems and methods for distributing urgent public information. Urgent public information, as the term is used herein, should be understood to mean information that is of relatively immediate interest to at least some segment of the general population. Examples of urgent public information therefore can include, inter alia, alerts promulgated by and/or in accordance with the Emergency Alert System, Amber Alerts and Homeland Security Advisories. Further examples can include weather information, for instance alerts from the National Weather Service, traffic information, and the like.

The term “alert” is sometimes used herein to denote information (e.g., urgent public information) that can be distributed according to embodiments of the invention. An alert can comprise textual information, audible information (including, e.g., speech, alert tones and the like), visual information (including, e.g., maps, photos, video signals and the like), and any other data or signals useful to convey urgent public information to a subscriber. An alert can be thought of as part of an “alert message,” which can comprise merely the alert itself and/or can include additional data, including for example alert information. The term “alert information” should be understood to mean information pertaining to the alert (e.g., metadata) that can be analyzed to determine whether and/or to whom the alert pertains and/or should be distributed. Alert information can include, but is not limited to, information about the geographic scope of the alert, when the alert was issued and/or when the alert expires, the type of alert (e.g., weather, Homeland Security, Amber Alert, etc.), and any other information that describes an alert and/or could be helpful in determining whether an alert should be distributed to a particular user. In some cases, alert information can be intrinsic to the alert. For example, a weather alert may be a single plaintext message, that includes, within the text of the alert, the time the alert was issued and/or the time the alert will expire. In such cases, embodiments of the invention can extract such alert information from the alert itself, and use the alert information to, inter alia, determine to which distribution address(es) the alert should be sent.

In other cases, however, alert information can be maintained separate from the substance of the alert. Merely by way of example, an alert may be transmitted as a formatted and/or tagged message (e.g., an XML message, etc.), such that the alert comprises one or more tagged fields within the message, and additional alert information is included in the message using one or more differently tagged fields. Thus, an alert message may include a field specifying an “alert initiation time” that signifies when the alert was first issued, as well as an “alert expiration time” that signifies when the alert will expire, such as in the case of weather alerts, for example. An alert message can have other fields of alert information as well, including for example, fields relating to the geographic scope of the alert, etc. Embodiments of the invention, therefore can parse an alert message.

Certain embodiments of the invention provide systems for distributing urgent public information to applicable subscribers. For ease of description, the term “subscriber” is used to refer to any entity that is capable of receiving urgent public information, and the term “provider” is used to refer to an entity that distributes urgent public information. In light of the entire disclosure, however, those skilled in the art will appreciate, that the use of these terms should not be interpreted to limit the scope of the invention to a particular relationship between a provider and a subscriber. In some cases, a provider can be the ultimate source of the urgent public information to be distributed; in other cases, the provider may function to receive an alert from another source (which might be a governmental agency such as the National Weather Service or the like) and distribute that information to subscribers. Likewise, a subscriber may the ultimate recipient of the alert and/or may also be a provider capable of distributing the alert to other subscribers. In particular embodiments, a provider can be a telecommunication service provider, and a subscriber can be a person, business or the like that receives telecommunication services from the provider.

FIG. 1A illustrates one exemplary system 100 that can be used to distribute urgent public information. The system 100 includes a communication network 104 , which can be any of several different types of communication networks. Merely by way of example, the network 104 can be the Internet. In other embodiments, the network 104 can be a telecommunication provider's network, including for example, an asynchronous transfer mode (“ATM”) network, a time-division multiplexed (“TDM”) network, a wireless network (including, for instance, cellular networks, personal communication service (“PCS”) networks, 802.11 networks, and the like), and/or a cable television distribution network. In many cases, the network 104 can be a composite of a plurality of these (and other) types of networks. In short, the network 104 can be any public or private network capable of transporting alert information as described herein. In some cases, the network 104 will be capable of transmitting packeted data, for instance, data formatted according to the TCP/IP suite of protocols. Based on the disclosure herein, those skilled in the art will understand that the network 104 may feature a plurality of routes, or paths, from one point (or device) to another.

The network 104 can be in communication with an alert distribution device 108 , which, in accordance with some embodiments, functions to receive alerts and distribute those alerts to appropriate subscribers. In some cases, the alert distribution device 108 can be a general-purposed server computer running one (or more) of a variety of server operating systems known in the art, including for example, Microsoft™ Windows™ (NT, 2000, XP or the like) or any of the UNIX™ or UNIX™-like operating systems (including Linux™, Solaris™, AIX™ and the like), as well, perhaps, as specialized software for providing the services discussed herein. Those skilled in the art will recognize, based on the disclosure herein, that other operating systems may be used as well, so long as they are capable of supporting the software used to perform the functions hereafter described. Those skilled in the art, therefore, will recognized based on the disclosure herein that he alert distribution device 108 can one or more processors that can execute instructions to perform many of the processing functions described herein. In many cases, the instructions can be software instructions stored on a storage medium such as those described below. In other cases, the alert distribution device 108 can comprise dedicated hardware for distributing urgent public information, such that some (or all) of the functionality of the alert distribution device 108 is embodied in hardware or firmware (for instance, any of the varieties of ROM, PROM, EPROM, EEPROM and the like).

In many embodiments, the alert distribution device 108 will include a storage medium 110 , which can be used to store both software instructions as well as operating data. Those skilled in the art will recognize that implementations of the storage medium 110 will vary in accordance with different embodiments: The medium 110 may be one ore more hard disk drives (including, for instance, a redundant array of inexpensive disks (“RAID”) system) attached either internally or directly externally to the alert distribution device 108 , as illustrated in FIG. 1A. In other cases, the storage medium 110 can be part of a storage area network and/or can be remote from the alert distribution device 108 . The location of the storage medium 110 is immaterial to the scope of the invention, so long as the storage medium 110 can be accessed by the alert distribution device 108 . Similarly, while for ease of description, the storage medium 110 is illustrated as a single device on FIG. 1A, the storage medium 110 can in fact be a plurality of storage media, situated at the same or different locations.

The storage medium 110 can comprise one or more databases, which can be used to store data and/or configuration settings for the system 100 . In accordance with some embodiments, one database can be used to store a table of logical address information associated with the subscribers, while another database can be used to store demographic information, including without limitation physical address information, associated with the subscribers. Merely by way of example, a first database can be used to store IP address information for each subscriber. The IP address information can be static or dynamic; for instance, in accordance with some embodiments, as discussed in detail below, each subscriber can be assigned a logical address using a dynamic addressing scheme such as the dynamic host configuration protocol (“DHCP”) known to those skilled in the art. Further, a second database can comprise information related to the physical address of the subscriber, such as a ZIP+4 code, street address, telephone number, GPS coordinates, and/or the like. In other embodiments, the system 100 can store a separate record of a physical hardware address (e.g., a MAC address, familiar to those skilled in the art) for each subscriber, such that each physical hardware address can be associated with a geographical location and/or a logical address. As described below, the system 100 can use these databases to determine, for a given alert message, which logical addresses should receive the alert message.

The alert distribution device 108 can also comprise (and/or be in communication with) an alert receiver 112 , which can receive alerts. In some cases, as illustrated in FIG. 1A, the alert receiver 112 can be a discrete device having an independent connection with an alert source 114 . In other cases, the functionality of the alert receiver 112 can be incorporated within the alert distribution device 108 . In either case, the alert receiver 112 can be capable of receiving urgent public information from the alert source 114 . In some instances, alert receiver 112 can include a wireless antenna capable of receiving RF signals from the alert source 114 . Those skilled in the art will recognize, for instance, that the federal Emergency Alert System broadcasts alerts using a particular radio frequency; the alert receiver 112 can be tuned to receive these and other signals over the airwaves. In other cases, the alert receiver 112 can receive alert information from an alert source 114 via other transports, including, for example the network 104 or another, perhaps similar network. Although for ease of reference, only one alert source 114 is illustrated on FIG. 1A, the alert receiver 112 can be configured to receive urgent public information from a plurality of alert sources; in addition, the alert distribution device 108 can be in communication with (and/or incorporate) a plurality of alert receivers for receiving urgent public information from a variety of alert sources.

The alert source 114 can be any device and/or entity that transmits or otherwise provides urgent public information. As mentioned above, in some cases, the alert source 114 can be affiliated with a federal, state or local governmental authority and/or other public entity. In other cases, the alert source 114 can be privately owned and/or operated, perhaps on a commercial bases. In some such cases, public information distributed from the alert source can be associated with a subscription service, and systems in accordance with embodiments of the invention can accommodate and/or facilitate a subscription service related to the distribution of the information from the alert source 114 .

The alert distribution device 108 can be in communication with a plurality of alert gateways 116 a , 116 b , 116 c , which can be operable to receive urgent public information from the alert distribution device 108 , for instance, via the network 104 . In this way, the alert distribution device 108 can function to distribute information (such as data, video signals, voice signals and the like, including urgent public information) to one or more of the plurality of alert gateways 116 a , 116 b , 116 c . The alert distribution device can include one or more interfaces for communicating with the alert gateways 116 , the alert source 114 and other devices. Such interfaces can include, for instance, wireless receivers and/or transmitters, network interface cards (such as Ethernet cards, fiber optic interfaces, such as FDDI cards), modems, and the like. In some cases, an interface can provide communication between the alert distribution device 108 and the communication network 104 . Thus, such interfaces can serve to receive and/or transmit alert messages as appropriate.

Those skilled in the art will appreciate that, in many cases, there may be multiple routes, or paths, through the network 104 between the alert distribution device 108 and the alert gateways 116 . Thus, in accordance with some embodiments, the alert distribution device 108 can be configured to select from among multiple such paths. Merely by way of example, the alert distribution device 108 can be configured to transmit an alert to a particular alert gateway (e.g., 116 a ) via one path (perhaps via a first interface, which is in communication with a first network) and, if that transmission is unsuccessful, to retransmit the alert to via a second path (perhaps via a second interface, which is in communication with a second network). In this example, the first and second networks might both be data networks connected to a common network, such as the Internet, which is further in communication with the alert gateway 116 a . Alternatively, the first and second networks might be different distribution networks; for example, the first network could be a cable distribution network, and the second network can be a public switched telephone network. Thus, if one of the networks is unavailable, the alert message can still be transmitted via another network. In other embodiments, the alert distribution device 108 can transmit via more than two paths.

In addition, in some embodiments, the network 104 can be distributed across large distances (indeed, in the case of the Internet, for instance, the network 104 can span the globe), and that the alert distribution device 108 may be located a significant physical distance from the alert receiver 112 and/or the alert source 114 . For that matter, the alert distribution device can be physically distant (e.g., in a different locality, state or country) from each of the alert gateways 116 , and one alert gateway 116 a can be physically distant from another alert gateway 116 b , such that an alert, for example, dealing with severe weather may be of interest to a subscriber associated with one alert gateway 116 a located in the path of the severe weather but not a subscriber associated with another alert gateway 116 b located elsewhere.

For this reason, among others, the alert distribution device 108 can be configured to select, based on the nature the information to be distributed and/or certain characteristics/preferences of the alert gateways 116 (and/or the subscribers associated with them), which of the alert gateways 116 appropriately should receive that information. Returning to the weather example, the alert distribution device 108 can be configured to route the severe weather alert only to the alert gateway 116 a located in the path of the severe weather. As illustrated by this example and discussed in further detail below, the location of an alert gateway can be one characteristic used to determine whether the alert gateway should receive the information. As discussed below, however, many other characteristics may be used to determine whether a given set of information should be distributed to a particular alert gateway.

As alluded to above, an alert gateway 116 can store the preferences of a subscriber, referred to herein sometimes as “subscriber preferences.” These preferences can be administered through a variety of interfaces, including those described in detail below, and can allow a user to configure the behavior of the gateway 116 in response to different types of alerts, as well as what types of alerts the subscriber would like to be notified about. In some cases, the alert gateway 116 can upload certain of these preferences (including, for instance, the types of alerts the subscriber would like to receive) to an alert distribution device 108 . In some embodiments, multiple subscribers can be associated with a single alert gateway 116 , and the alert gateway 116 can be configured to support the preferences of multiple subscribers and/or confirm reception of a given alert by each associated subscriber that should receive that alert. A subscriber can, in some instances, log on to the alert gateway 116 (e.g., using a subscriber identifier and/or a password) and administer the preferences for that subscriber. In some embodiments, the preferences for multiple subscribers can be maintained only at the gateway 116 , such that the alert distribution device 108 is only aware of the gateway and sends all applicable alerts to the gateway 116 generally, allowing the gateway to determine the subscribers to which an alert should be sent, while in other embodiments, the alert distribution device 108 can be aware of distinct subscribers associated with the gateway 116 can send alert messages specifically for a particular subscriber(s).

In accordance with various embodiments of the invention, alert gateways can take several forms. Usually (but not always), they are stationary and can be affixed to a particular subscriber location, such as a house, apartment, office building or the like; in some cases, however, an alert gateway may not be stationary and can, for instance, be located in an automobile or the like. In some cases, an alert gateway can even be a mobile device, such as a PSC phone, pager or the like. In any event, an alert gateway may incorporate location-determining equipment, such as a GPS receiver and/or can be capable of being located through triangulation procedures familiar to those skilled in the art. In certain embodiments, an alert gateway can comprise a demarcation device, including for instance, demarcation devices and/or network interface devices (“NID”) such as those described in detail in commonly-owned, copending U.S. application Ser. Nos. 10/448,249, 10/367,597, 10/367,596, 10/356,688, and 10/356,338, all previously incorporated by reference.

In addition, devices similar to the demarcation devices and/or NIDs described in the applications previously incorporated by reference and the following commonly-assigned applications can comprise and/or be used as (or in conjunction with) alert gateways in accordance with some embodiments of the invention: U.S. patent application Ser. No. 10/377,280, filed Feb. 27, 2003 by Phillips et al. and entitled “ADSL/DBS NETWORK INTERFACE DEVICE, METHODS AND SYSTEMS FOR USING SAME”; U.S. patent application Ser. No. 10/445,275, filed May 23, 2003 by Casey et al and entitled “REAL-TIME MEDICAL MONITORING APPLICATION WITH A NETWORK INTERFACE DEVICE”; U.S. patent application Ser. No. 10/452,996, filed Jun. 2, 2003 by Phillips et al. and entitled “SYSTEMS AND METHODS FOR DISTRIBUTING CONTENT OBJECTS IN A TELECOMMUNICATION SYSTEM”; U.S. patent application Ser. No. 10/611,324, filed Jun. 30, 2003 by Casey et al. and entitled “SYSTEM AND METHOD FOR COOLING OF A NETWORK INTERFACE DEVICE”; and U.S. patent application Ser. No. 10/625,863, filed Jul. 22, 2003 by Phillips et al. and entitled “PERSONAL COMMUNICATION SERVICE NETWORK INTERFACE DEVICE.”

In accordance with certain embodiments of the invention, an alert gateway may be in communication with one or more pieces of subscriber equipment. Subscriber equipment (which can include devices sometimes referred to as “consumer premises equipment” or “customer premises equipment”) can include a variety of communications equipment and/or consumer electronics, including, merely by way of example, telephones (POTS, SIP, VoIP, PBX, PCS, cellular, etc.), video display devices (including televisions, computer monitors, LCD panels, video game consoles and the like), set-top boxes, audio equipment, pagers, and the like, as well as other devices described in detail in the applications previously incorporated by reference.

Turning now to FIG. 1B, a generalized schematic drawing 120 illustrates the relationship of components of certain embodiments the invention at a subscriber premises 124 . An alert gateway 116 can be located at the subscriber premises 124 , and may, in some cases, be affixed to an exterior wall of the subscriber premises 124 , enabling the gateway 116 to be serviced by provider personnel without disturbing the occupants of the subscriber premises 124 . In other embodiments, the alert gateway 116 may be located entirely within the subscriber location and/or may comprise two or more physically separate elements, some of which may be located outside and/or attached to an exterior wall of the subscriber premises, and some of which may be located within the subscriber premises, as discussed in further detail infra.

The alert gateway 116 can receive alert information from a variety of sources, including, merely by way of example, alert distribution devices described herein, using any appropriate communication medium (not shown in FIG. 1B). In addition, the alert gateway 116 can be coupled to one or more internal transport media 128 a - c , which can comprise any medium capable of transmitting data packets, including without limitation those media described, for instance, in various of the applications previously incorporated by reference. Notably, embodiments of the alert gateway 116 can support a variety of media topologies, including star (with the alert gateway 116 optionally serving as the hub) and bus configurations, as illustrated by the exemplary configuration of media 128 a - c in FIG. 1B. In addition to wired media, the alert gateway 116 can include and/or be in communication with a wireless transceiver 130 , which can allow the alert gateway to communicate with a variety of wireless subscriber equipment through any of a variety of wireless communication protocols known in the art, including the IEEE 802.11 series of protocols, the Bluetooth™ standard, various cellular and/or PCS communication protocols, and other wireless communication methods discussed in further detail in the applications previously incorporated by reference.

Thus, in accordance with embodiments of the invention, the alert gateway 116 can communicate with one or more elements of subscriber equipment 132 a - f , using any of the transport media (wired and/or wireless) discussed above. In addition, the alert gateway can incorporate and/or can be in communication an alert notification device 136 , through one or more of the transport media previously described, including in particular a serial (e.g., RS-232 and/or Universal Serial Bus) connection, an Ethernet connection, an HPNA connection, and the like. In accordance with some embodiments, the alert notification device 136 is a dedicated piece of hardware that is configured to receive alert information from the alert gateway 116 and take some action to notify the subscriber that an alert has been received. Merely by way of example, in certain embodiments, the alert notification device can include a visual signal, including without limitation one or more light emitting diodes, as well as an audible signal, including without limitation, a siren, an alert tone generator, and the like. Thus, when the alert gateway 116 transmits alert information to the alert notification device 136 , the alert notification device 136 can display the visual signal and/or display the audible signal to notify the subscriber that an alert has been received.

In a particular exemplary embodiment, the alert notification device is a microprocessor-based device comprising a display screen (such as an LCD screen) in communication with the microprocessor, an alert lamp (such as an LED) in communication with the microprocessor, an input device such as a button, also in communication with the microprocessor. This exemplary alert notification device can also include a communication interface, such as a serial (e.g., RS-232) interface to provide connectivity with, for example, an alert gateway. Thus, upon receipt of an alert from an alert gateway, the microprocessor can instruct the LED to flash and the LCD to display the text of the message, and a subscriber can press the button to indicate receipt of the alert, at which point the alert text will be erased, the LED will go dark, and, optionally, a confirmation message will be sent to the alert gateway. It should be appreciated that other embodiments of alert notification devices may include enhancements and modifications, including speakers, more detailed display devices, and the like.

As discussed further infra, in accordance with certain embodiments of the invention, alert information may be prioritized and/or categorized according to the information included in the alert (e.g., the severity of the condition prompting the alert, the geographic scope of the alert, the subscriber's preferences, and the like). In such embodiments, the alert notification device 136 can be configured to vary the alert notifications in relation to the nature of the alert. Merely by way of example, for relatively low priority alerts, the device 136 merely may display a simple visual signal, such as a flashing LED, while for relatively more urgent alerts, the device 136 may periodically repeat an audible alert and/or may display a relatively more intense visual alert (e.g., a brighter or different colored LED, strobing lights, etc.).

In accordance with further embodiments, the alert notification device 136 can include capabilities to inform the subscriber of the substance of the alert, instead of or in addition to merely signaling the subscriber that an alert has been received. Merely by way of example, some alert notification devices can include a text screen, which can allow the subscribe to view the text of an alert, while others include a speaker and other circuitry known in the art to allow the notification device 136 to audibly inform the user of the text of the alert. (As discussed below, in accordance with certain embodiments, the alert gateway 116 can process the alert information by, inter alia, converting speech to text and/or text to speech; the alert notification device 136 can receive and display/play this processed alert information and/or can include the necessary hardware and/or software to perform such conversions as well). In certain implementations, the alert notification device 136 can include a display screen, which can be used to view visual alert information (which can include, inter alia, graphics, maps, video information and the like).

As mentioned discussed in further detail below, certain embodiments of the invention allow for confirmation that a subscriber has received alert information. Hence, the alert notification device 136 optionally can include a subscriber feedback device, which can be any apparatus that allows the subscriber to interact with the alert notification device 136 . The subscriber feedback device, therefore, can be as simple as a single button the subscriber can push to indicate that the subscriber has received the alert; alternatively, the subscriber feedback device can facilitate relatively more complex feedback, and can include a microphone and/or voice recognition facilities, a keyboard and/or pointing device and the like. Thus, certain embodiments can allow for more than mere confirmation that the subscriber has received the alert: Using the subscriber feedback device, the subscriber can request more information about the alert, indicate that he is interested (or not interested) in future related alerts, and the like. This feedback can be transmitted from the alert notification device 136 to the alert gateway 116 and, if necessary transmitted from the alert gateway 116 to an alert distribution device, which may act upon the feedback by sending more information, changing saved preferences for the subscriber, etc.

Turning now to FIG. 1C, a schematic diagram 140 illustrates the relationship between the alert gateway 116 and various subscriber equipment located within a subscriber premises 124 . In the illustrated embodiment, the alert gateway 116 can be coupled to a plurality of transport media 144 a -I, which can provide communication capability between the alert gateway 116 and a variety of subscriber equipment (e.g., 148 , 152 , 156 , 160 , 164 , 168 , 172 , 176 , 180 , 184 , 186 , 188 ). Merely by way of example, in the illustrated embodiment, the alert gateway 116 can communicate with a television 148 . The television 148 can, for instance, be used to display visual alert information including, merely by way of example, graphics, maps, textual information, and the like, as well as audio alert information. In accordance with some embodiments (including without limitation certain embodiments discussed in various of the applications previously incorporated by reference), the alert gateway 116 can function as a set-top box.

In some such embodiments, the alert gateway 116 can be configured, upon receipt of alert information, to superimpose that alert information over the existing television signal being transmitted on transport medium 144 a to television 148 , including, for instance, as a picture and picture signal or as a “ticker” running across the bottom, top, etc. of the screen of the television 148 . In accordance with other embodiments, the alert gateway 116 can be configured to tune the television 148 to a particular channel and display the alert information on that channel, and/or to display a visual and/or audible alert indicating to the subscriber that alert information has been received and that, if the subscriber wishes to review the alert, the subscriber can tune the television 148 to a particular channel and/or provide other prompting, such as pressing a particular button on a television remote control. Hence, the alert gateway 116 optionally can be configured to receive input from the television 148 and/or a remote control associated with the television 148 and/or the alert gateway 116 . In this way, the subscriber can, if desired, respond to the alert information as discussed above.

The alert gateway 116 can also be in communication with an IP device 152 . The IP device 152 can be any type of device that is capable of receiving packeted data, in particular Internet Protocol data. Several types of IP devices are described in the applications previously incorporated by reference and various of those devices can be incorporated within or accommodated by embodiments of the present invention. Thus, the alert gateway 116 may be configured to transmit alerts via a transport medium 144 b to any device 152 that is capable of receiving and/or transmitting IP data. Consequently, embodiments of the invention allow for a robust architecture in which the alert gateway 116 can transmit IP-formatted alert information to any of a variety of devices capable of receiving IP data.

In other embodiments, the alert gateway 116 can communicate with an alert notification device 156 , perhaps in the manner described above with reference to FIG. 1B. In still other embodiments, an alert gateway 116 can communicate with IP set-top box 160 , and, by extension, with a television 164 . In this way, the interaction with television 164 can be similar to the interaction described above with respect to television 148 with the exception that the set-top box 160 can perform intermediation tasks between the alert gateway 116 and the television 164 such as converting signals from an IP-based format (MPEG, etc.) to a television signal (NTSC, PAL, HDTV, etc.). The set-top box 160 can perform other functions as well, including, without limitation, those described in various of the applications already incorporated by reference.

In accordance with certain embodiments of the invention, the alert gateway 116 can communicate with a variety of telephones, including, merely by way of example, an analog (POTS) telephone 168 , a telephone complying with the session-initiation protocol (“SIP”) 172 , a video phone 176 , as well perhaps as an Internet access device (IAD), 180 which can be connected to an analog telephone 184 . In addition, a phone 186 complying with the voice over Internet protocol standard (“VOIP”) can be attached to the alert gateway 116 as well. Those skilled in the art will appreciate that different embodiments can feature multiple phones of these and other different types, including, for instance private branch exchange (“PBX”) systems.

Although each of the telephones 168 , 172 , 176 , 184 can include a variety of features that can be employed in accordance with various embodiments of the present invention, these various embodiments all can have in common the ability to send a ring signal from the alert gateway 116 to the phone, causing the phone to ring upon reception of alert information by the alert gateway 116 . Hence, the ringing of the phone can serve as a signal to the subscriber that an alert has been received, similar to the way that a ringing phone generally signifies a that telephone call has been received. (Somewhat similarly, the alert information could be stored as a message in a voice messaging system, which could be managed and/or stored by a demarcation device in accordance with embodiments disclosed in the previously incorporated applications, at the alert gateway, in a telecommunication provider's network, on an answering machine, and/or in other ways known in the art. In this way, embodiments of the invention optionally could allow the voice messaging system's standard message indicator to serve as an alert notification indicator.) In accordance with various embodiments, a different ring tone, pattern etc. can be used to signify an alert than is used to signify an incoming telephone call. In the event a subscriber answers the ringing telephone, the alert information can be played to the user audibly. In addition, some phones, for example the video phone 176 , may allow for the display of information and/or video signals and the alert gateway 116 can display textual information and/or video information corresponding to the alert received by the gateway 116 .

Optionally, the alert gateway 116 can be configured to prompt the subscriber to press a button on the telephone to indicate reception of the alert information. Alternatively, the alert gateway 116 can be configured to accept as confirmation that the alert was received the mere fact that the subscriber answered the ringing telephone. In other embodiments, the alert gateway 116 can be configured to respond to prompting from the subscriber (e.g., voice prompting and/or pressing a key) to provide more information about the alert and/or to respond in some other manner to the alert.

The alert gateway 116 also can be in communication with a computer 188 . The computer 188 can be any kind of computing device, including merely by way of example, a personal computer, a laptop computer, a handheld computer or the like, as long as it is capable of sending data to and/or receiving information from the alert gateway 11 6 . In some embodiments, the computer 188 can be configured with specialized software to enable it to receive information from the alert gateway 116 . Alternatively, the computer 188 can receive alert information from the alert gateway in the form of Internet protocols such as HTTP, HTML, and the like, allowing a computer with no specialized software to receive the alert information using standard Internet communication applications (e.g., web browsers, electronic mail clients, and the like). Thus, the alert gateway 116 can be configured to display a visual and/or audible signal on the computer 188 , perhaps in the form of a pop-up window, audible alert tone, e-mail message, etc., informing the subscriber that an alert has been received by the alert gateway and/or providing the substance of the alert information. As discussed previously, the PC 188 can include any of a variety of input devices known in the art enabling the user to respond to the alert by, for instance, closing the alert window, clicking on a button indicating that the alert has been received, clicking on a button requesting more information about the alert, or the like.

In addition, the alert gateway 116 can be in communication with a wireless device 192 , such as a cellular phone, cordless phone, PCS phone, wireless e-mail device, portable computer (perhaps with a wireless network card), and/or the like. As discussed earlier, the alert gateway can be configured with (as illustrated in FIG. 1C) a transceiver for communicating directly with the wireless device 192 and/or can communicate with the wireless device 192 through an intermediary such as a separate wireless service (e.g., a wireless telephone provider, a wireless e-mail provider, etc.). Thus, the alert gateway 116 can communicate by signaling the wireless device 192 with a wireless signal and/or communicating through a separate provider (such as, for instance, placing a telephone call through the public switched telephone network to a telephone number associated with the wireless device 192 and/or sending e-mail through the Internet to the wireless device 192 ). Similar to the other devices discussed herein, the wireless device 192 can configured with a device such as a telephone keypad, keyboard, etc., which can be used to allow a subscriber to respond the alert information was received, request more information and the like. Alternatively, the wireless device 192 itself automatically may broadcast a message to the alert gateway 116 indicating that it received the alert information.

In many cases, the alert gateway includes a storage medium (which can include any of those described in the applications previously incorporated by reference). The storage medium can store gateway- and/or subscriber-specific information, including, by way of example, the physical location of the alert gateway. The physical location can be expressed in several different ways, including street address, area code, zip code, GPS coordinates, and the like. Other gateway and/or subscriber-specific information can include preference information about the types of alerts the subscriber is interested in receiving (and/or not receiving), and demographic information about the subscriber. Demographic information about a subscriber can include a broad range of biographical and other information about a subscriber, including merely by way of example and without limitation, the age of the subscriber, health information about the subscriber (including information about allergies and other sensitivities), information about the subscriber's commuting habits, information about the subscriber's purchasing habits, and the like. In addition, demographic information can include information about other members of a subscriber's household. In some embodiments, the subscriber can specify which demographic information is stored by the system.

As mentioned above, in certain embodiments, the alert gateway can be incorporated within and/or be in communication with a demarcation device and/or a NID, including for instance, any of a variety of devices disclosed in the applications previously incorporated by reference. Merely by way of example, FIG. 2A illustrates a NID 200 that can incorporate and/or be in communication with an alert gateway, in accordance with embodiments of the present invention. For purposes of this disclosure, a NID can be considered a device that can serve as the interface between an external transport medium and an internal transport medium and, in particular can act to receive alert information from an alert distribution device (or another source) and distribute that information throughout a subscriber premises and/or to an alert gateway, as appropriate.

Turning now to FIG. 2A, one exemplary embodiment of a NID 200 is illustrated. In the illustrated embodiment, NID 200 comprises a clamshell design, with a lid portion 204 and a body portion 208 connected by hinges 212 A, 212 B. Turning now to FIG. 2B, it can be seen that body portion comprises a network area 216 and a customer area 220 . Generally, network area 216 is adapted to receive a cover and is designed generally to be accessible only to personnel authorized by the telecommunication service provider. In contrast, when the NID 200 is open, the customer can access the customer area 220 to add, remove or modify components as desired. In this and other ways, NID can serve to isolate the telecommunication service provider's network from the customer's network, as described above. As discussed below, lid portion 204 can contain a processing system 244 .

Returning to FIG. 2A, NID 200 can include a first interface 228 for communicating with the provider's external transport medium. Those skilled in the art will recognize that, in some embodiments, as described above, the external transport medium can be the twisted-pair copper “local loop” running from the customer's premises to the telecommunication service provider's local office, and the first interface 228 can allow for the attachment of the local loop to the NID 200 . As discussed above, in other embodiments, the external transport medium can be any of a variety of other media, including satellite transmissions, wireless transmissions, coaxial cable, optical fiber, and the like. In fact, in certain embodiments, the external transport medium can comprise multiple transport media (of the same or different types), for which the NID 200 could include multiple interfaces. The NID 200 can receive alert information on the first interface 228 via the external transport medium.

In some embodiments, the NID 200 can function to logically couple or bond a plurality of external transport media to one another, seamlessly increasing the bandwidth available to the customer premises. For instance, a customer premises might have a satellite link to one provider and an ADSL link to another provider, and the NID 200 could combine or multiplex these two links to provide an apparent single, higher-bandwidth connection to the customer premises. Similarly, those skilled in the art will recognize that, in certain of these embodiments, a particular external transport medium (for instance, a satellite link) may be more well-suited to one way transmission of telecommunication information; in such cases, the NID 200 could use a second external transport medium (for instance, an ADSL link) to allow transmission in the other direction. In other embodiments, the NID 200 could be configured to receive alert information from one or more of the external media and/or send confirmation (and/or other) messages to the alert distribution device via one or more of the external media (which may or may not be the same external media as the those used to receive the alert information).

The interface 228 can be coupled to a discrimination device 232 , which can be operative to separate information sets received on the first interface 228 (and, conversely, aggregate information sets for transmission on interface 228 ). Merely by way of example, in particular embodiments, the discrimination device 232 can separate POTS information from other telecommunication informa
