Abstract:
A system and method for providing medical, contact and location information of a subscriber initiating an emergency call, directly to the nearest Public Safety Answering Point (PSAP) at the time of the receipt of the emergency call. Upon the initiation of an emergency call, the existing infrastructure equipment of a communication service provider is able to access a central server containing the medical and contact information of a subscriber, and relay that information directly to a call center to speed response time and response effectiveness. As well, the location of the emergency call may be provided in order for the call center to forward this information along with the medical and contact information to the most proximate Public Safety Answering Point (PSAP) to the call being made. Alternatively, an agent resident on a communications device used by a subscriber can store and maintain medical and contact information of the subscriber, as well directly transmit the medical and contact information to the call center.

Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates generally to the field of emergency communications. More specifically, the present invention relates to a communication network and associated method for quickly and easily storing, retrieving and providing information related to the subject of an emergency communication. 
       BACKGROUND OF THE INVENTION 
       [0002]    This section is intended to provide a background or context to the invention that is recited in the claims. The description herein may include concepts that could be pursued, but are not necessarily ones that have been previously conceived or pursued. Therefore, unless otherwise indicated herein, what is described in this section is not prior art to the description and claims in this application and is not admitted to be prior art by inclusion in this section. 
         [0003]    Emergency notification systems have been in use for many years, routing emergency calls to proper response authorities such as the local police, fire department, ambulance service, etc., where dialing 9-1-1 denotes that a call is an emergency call. In approximately over 93% of locations in the United States and Canada, dialing 9-1-1 from any telephone will connect a caller to an emergency dispatch center called a Public Safety Answering Point (PSAP), which can send emergency response personnel to the caller&#39;s location in an emergency.  FIG. 4  shows a typical communications network in which basic 911 service is implemented. A user makes a 911 call using telephone  400  indicating that the user is in some sort of distress. The call is routed to a local exchange carrier (LEC) switch  405  and forwarded to a 911 tandem switch  410 . Upon receipt of the 911 call, the 911 tandem switch  410  routes the 911 call to one of a plurality of PSAPs  415   a ,  415   b , or  415   c . Alternatively, the LEC switch  405  can route the 911 call directly to one of the PSAPs  415   a ,  415   b ,  415   c . It should be noted that a PSAP is a designation used to describe a location where the 911 call is terminated, answered, processed, and the nature of the distress or emergency is determined and assessed. An automatic call distributor (ACD), a call center, or a private branch exchange (PBX) switch can function as a PSAP, or PSAP equipment can include an ACD, call center, or PBX switch. An operator (not shown) of PSAP  415   b  processes the 911 call and forwards it to an appropriate response center or agency, e.g., an ambulance service  420 , a local fire department  425 , or a local police department  430 . 
         [0004]    In some areas and through some wireless carriers, Enhanced 911 (E911 and E112 (EU)) is available through third party companies, which automatically gives the PSAP the caller&#39;s location, even on cellular devices.  FIG. 5  is an example of a communications network in which E911 service is implemented. The network operates as described with reference to  FIG. 4 . However, instead of only voice data being sent from telephone  400 , Automatic Number Identification (ANI) information is also sent through the communication network. Originally, ANI information was utilized to assist a telephony company in accessing toll charges for long distance calls. Advances in technology, however, allowed ANI information to be used in relaying needed information to a PSAP for 911 response as well. Therefore, upon receipt of a 911 call at the 911 tandem switch  410 , the ANI information associated with telephone  400  is read, thereby allowing 911 tandem switch  410  to send the callback number of telephone  400  to the display of a workstation at the appropriate PSAP  415   a ,  415   b , or  415   c . With this callback number information, the appropriate PSAP is able to access a 911/Automatic Location Identifier (ALI) database  540  and retrieve the caller&#39;s physical address or ALI. 
         [0005]    However, when regular 911 calls are made from mobile telephones, the call may not be routed to the closest PSAP, and the call taker does not receive a callback phone number or the location of the caller. This presents life threatening problems due to lost response time if callers are unable to speak or don&#39;t know where they are, or if they don&#39;t know their mobile telephone callback number and the call is dropped. The National Emergency Number Association (NENA) is an organization that was created to foster technological advancements, availability, and implementation of a universal emergency telephone number system. To address the problems present in wireless 911, a three phase plan was enacted. 
         [0006]    The most basic of these phases, sometimes called Wireless Phase 0, simply provides that when a caller dials 9-1-1 from a wireless telephone, an operator at a PSAP answers. The operator may be at a state highway patrol PSAP, at a city or county PSAP up to hundreds of miles away, or at a local PSAP, depending on how the wireless 911 call is routed. 
         [0007]    Wireless Phase I is the first step in providing better emergency response service to wireless 911 callers. When Wireless Phase I has been implemented, a wireless 911 call will come into a PSAP with the mobile telephone callback number. This is important in the event the call is dropped, and may even allow PSAP operators to work with a wireless company to identify the wireless subscriber. However, Wireless Phase I still does not help call takers locate emergency victims or callers. 
         [0008]    To locate wireless 911 callers, Wireless Phase II may be implemented in an area by local 911 systems and wireless carriers. Wireless Phase II will allow operators to receive both the caller&#39;s mobile telephone number and their location information. This is accomplished by requiring new mobile telephones to provide their latitude and longitude to PSAP emergency response operators in the event of a 911 call. Carriers may choose whether to implement this via GPS chips in each phone, or via triangulation between cell towers. In addition, Wireless Phase II requires carriers to connect 911 calls from any mobile telephone, regardless of whether that phone is currently active. Due to limitations in technology (of the mobile telephone, cell towers, and PSAP equipment), a mobile callers&#39; geographical information may not always be available to the local PSAP. 
         [0009]    However, companies have recently developed technologies to overcome this problem and better utilize the triangulation techniques in order to locate the caller&#39;s proximity to a tower. Signal strength, as intercepted by the nearest cellular towers can at least narrow the location to a specific area, which may allow for emergency response teams to respond more quickly. Companies have developed technologies exceeding the FCC Phase II regulations for location accuracy, even developing technology to handle rural locations. However, these technologies still do not provide all pertinent information to the nearest PSAP. 
         [0010]    The networks described above remain very limited in functionality. For example, medical information relating to a caller must still be gleaned by a PSAP operator conversing with the caller. If the caller has become incapacitated or is otherwise unable to speak, the PSAP operator has no way of knowing how best to aid the caller. It is left to emergency response personnel to determine this and act upon arriving at the caller&#39;s location. Therefore, it would be helpful to know any pertinent medical information beforehand as well as the proximate location of the caller. It would also be helpful to inform interested parties, such as parents of a child, if the child has initiated a 911 call. There have been attempts to provide medical history information and wireless location to PSAP operators and systems have been developed to notify third parties of 911 calls. However, these systems and methods require additional infrastructure equipment that are not easy to integrate into existing communication networks. Moreover, these systems and methods still require extra steps of a PSAP operator and extra time, for example, manually accessing and retrieving medical data regarding a 911 caller as well as attempting to retrieve the location of the caller from the caller themselves or from a third party network database. Therefore, an improvement is needed to overcome the extra time, steps, and hassle to quickly locate a caller, retrieve their medical information and provide this to the nearest PSAP. 
       SUMMARY OF THE INVENTION 
       [0011]    Various embodiments of the present invention comprise a system and method for providing medical, contact and location information associated with a subscriber, to the nearest response personnel, such as PSAP operators, local fire and police departments, and the like. The medical and contact information can include, but is not limited to a subscriber&#39;s name, blood type, date of birth, language(s) spoken, and emergency contact(s). As well, the location information may provide a proximate location to a cellular tower, structure or exact latitude and longitude coordinates. When a subscriber initiates an emergency 911 call, an agent in the telephone sends an identifier through the communication network to a central server. The identifier allows the subscriber&#39;s associated medical and contact information to be retrieved from the central server, As well, the identifier may be routed through a third party database, in order to locate the caller location through GPS, triangulation, or signal angle and time of arrival at one tower. After receiving the location information at the central server, this information along with the subscriber&#39;s associated medical information is relayed to a response personnel, or PSAP, within closest proximity to the subscriber. In another embodiment, the location information may be processed and retrieved through the central server at the first call center, not requiring communication with a third party. In addition, a message can be sent to any contact(s) retrieved in the subscriber&#39;s associated medical and contact information at substantially the same time the 911 call is initiated, alerting that contact(s) that a 911 call has been made. 
         [0012]    In further embodiments, a method is provided for providing subscriber information from a call on a wireless network by receiving the caller&#39;s identifier information and then forwarding it to a first communication network and forwarding it to a database in order to provide it to the nearest PSAP location. 
         [0013]    Various embodiments of the present invention allow for better and easier implementation of emergency 911 services. The nearest PSAP operators can receive all the necessary information for aiding a subscriber in an emergency situation immediately without having to manually access outside data sources. As well, in one embodiment, this information may be relayed to the most proximate PSAP by a person other than the caller, who may be distressed and unable to properly communicate in an emergency situation. Existing service providers do not have to invest in additional infrastructure, nor do service providers have to modify their respective system architectures. However, one embodiment provides that the existing service provider may be the third party to aid in locating the most proximate PSAP through their databases. 
         [0014]    These and other advantages and features of the invention, together with the organization and manner of operation thereof, will become apparent from the following detailed description when taken in conjunction with the accompanying drawings, wherein like elements have like numerals throughout the several drawings described below.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0026]      FIG. 1  shows a system  10  in which the present invention can be implemented and utilized, comprising multiple communication devices that can communicate through a network. The system  10  may comprise any combination of wired or wireless networks including, but not limited to, a mobile telephone network, a wireless Local Area Network (LAN), a Bluetooth personal area network, an Ethernet LAN, a token ring LAN, a wide area network, the Internet, i.e., voice over Internet Protocol (VOIP), etc. The system  10  may include both wired and wireless communication devices. 
         [0027]    For exemplification, the system  10  shown in  FIG. 1  includes a mobile telephone network  11  and the Internet  28 . Connectivity to the Internet  28  may include, but is not limited to, long range wireless connections, short range wireless connections, and various wired connections including, but not limited to, telephone lines, cable lines, power lines, and the like. 
         [0028]    The exemplary communication devices of the system  10  may include, but are not limited to, a mobile telephone  12 , a combination PDA and mobile telephone  14 , a PDA  16 , an integrated messaging device (IMD)  18 , a desktop computer  20 , and a notebook computer  22 . The communication devices may be stationary or mobile as when carried by an individual who is moving. The communication devices may also be located in a mode of transportation including, but not limited to, an automobile, a truck, a taxi, a bus, a boat, an airplane, a bicycle, a motorcycle, etc. Some or all of the communication devices may send and receive calls and messages and communicate with service providers through a wireless connection  25  to a base station  24 . The base station  24  may be connected to a network server  26  that allows communication between the mobile telephone network  11  and the Internet  28 . The system  10  may include additional communication devices and communication devices of different types. 
         [0029]    The communication devices may communicate using various transmission technologies including, but not limited to, Code Division Multiple Access (CDMA), Global System for Mobile Communications (GSM), Universal Mobile Telecommunications System (UMTS), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Transmission Control Protocol/Internet Protocol (TCP/IP), Short Messaging Service (SMS), Multimedia Messaging Service (MMS), e-mail, Instant Messaging Service (IMS), Bluetooth, IEEE 802.11, etc. A communication device may communicate using various media including, but not limited to, radio, infrared, laser, cable connection, and the like. 
         [0030]      FIGS. 2 and 3  show one representative mobile telephone  12  within which the present invention may be implemented. It should be understood, however, that the present invention is not intended to be limited to one particular type of mobile telephone  12  or other electronic device. The mobile telephone  12  of  FIGS. 2 and 3  includes a housing  30 , a display  32  in the form of a liquid crystal display, a keypad  34 , a microphone  36 , an ear-piece  38 , a battery  40 , an infrared port  42 , an antenna  44 , a smart card  46  in the form of a UICC according to one embodiment of the invention, a card reader  48 , radio interface circuitry  52 , codec circuitry  54 , a controller  56  and a memory  58 . Individual circuits and elements are all of a type well known in the art. 
         [0031]    A typical wireless emergency 911 network is shown in  FIG. 6 . A caller using mobile telephone  600  initiates a wireless 911 call. The nearest serving cell tower  610  picks up the wireless 911 call and relays it to a mobile switching center (MSC)  620 . The MSC  620  operates much like a landline LEC switch and forwards the wireless 911 call to 911 tandem switch  410 . It should be noted that the MSC  620  is usually a part of or operated by one of a plurality of local wireless service providers. The wireless 911 call is then received at the PSAP  415   b , along with wireless ANI data that indicates the wireless telephone callback number of mobile telephone  600 . The PSAP  415   b  can relay the relevant information to the appropriate response center or agency  420 ,  425 , and/or  430 . In addition, there are known methods of sending additional ANI-related data with the wireless 911 call, such as information regarding the cell face of the cell tower  610  that received the wireless 911 call, or the cell tower  610  itself. This information can be used to approximate within several hundred square meters, where the wireless 911 call was made from. 
         [0032]    As mentioned above, Wireless Phase II promulgated by NENA requires determination of the location of mobile telephones making 911 calls. One method of accomplishing this is through base station or cell tower triangulation. Each base station or cell tower, for example, cell tower  610 , measures the amount of time it takes to receive a mobile telephone&#39;s signal when it makes a wireless 911 call. This time data is translated into distance data, which can be used for estimating how far the mobile telephone is from the base station or cell tower. This distance data is then cross-referenced with distance data from at least one other base stations or cell towers that received the mobile telephone&#39;s signal to arrive at longitudinal and latitudinal coordinates for that mobile telephone. Alternatively, the mobile telephone itself can triangulate its location by cross-referencing time-synchronized signals sent from multiple base stations or cell towers. The angle at which a mobile telephone&#39;s signal arrives at a base station or cell tower can also be determined using antenna arrays. This angle data can also be cross-referenced with angle data from other base stations or cell towers, and the mobile telephone&#39;s location can be triangulated. In addition, many mobile devices are now equipped with global positioning system (GPS) receivers that can receive GPS signals from GPS satellites to determine location. 
         [0033]      FIG. 7  shows one embodiment of the present invention for providing medical and contact information services to subscribers. The elements of the wireless emergency 911 network of  FIG. 6  are utilized in the system architecture of the present invention, with the exception of the 911 tandem switch  410 . Replacing the 911 tandem switch  410  is a central server  700 . The central server  700  implements and manages all application modules for effecting the medical information service. It should be noted that such an implementation of the present invention requires no infrastructure investment from service providers. Existing wireless networks and service providers, e.g., Verizon, Cingular, T-Mobile, Sprint/Nextel, USCellular, etc. need only install an agent on mobile telephones operating on their respective networks. The agent can be optimized for each service provider or can be coded as a universal application or module, capable of being utilized on any service provider equipment. 
         [0034]    The agent for the mobile telephones can be added after being locked to a specific carrier by that service provider, or can be installed by the mobile telephone manufacturer, e.g., Nokia Corporation. Furthermore, the agent can be implemented directly in the mobile telephone itself or on a SIM card/microchip that can be removably installed/inserted into the mobile telephone. The agent is responsible for detecting dual tone multifrequency (DTMF) signals or a dedicated telephone keypad button/softkey representing 9-1-1. If logic in the mobile telephone is not present, the agent can also detect and distinguish between the actual dialing of a 911 call and when the digits 9-1-1 are merely a part of another telephone number or key-pressing sequence. The agent can even be coded to allow a 911 caller to input a unique identifier to identify him or herself in the event he/she must initiate a 911 call from a telephone other than their own, or if a person is initiating the 911 call on behalf of the person in distress. Additionally, a cancellation function can be provided by the agent to prevent false 911 calls from being routed. 
         [0035]    Coding the agent can be done using, but not limited to, the Binary Runtime Environment for Wireless (BREW) platform, which is an air-interface independent platform originally used for downloading and running small mobile applications, Java Platform, Micro Edition (J2ME), a collection of Java application programming interfaces (APIs), or another OEM software platform. 
         [0036]    In the one embodiment of the present invention, the central server  700  stores and maintains important medical and contact information for subscribers, including, but not limited to, a subscriber&#39;s name, date of birth, language(s) spoken, emergency contact(s), blood type, medications, allergies, weight, eye color, driver&#39;s license number, living will information, and organ donor information. The medical information services provided by the various embodiments of the present invention can be divided into subscription levels or packages, where all or some subset of the above medical information is stored and maintained for a subscriber. For example, a basic medical information services package can include storing and maintaining a subscriber&#39;s name, date of birth, language(s) spoken, emergency contact(s), and blood type. A premium medical information services package can include that information found in the basic service, plus the subscriber&#39;s medications, allergies, weight, eye color, driver&#39;s license number, living will information, and organ donor information. 
         [0037]    In order to store and maintain subscribers&#39; medical and contact information, a management console is provided through which a subscriber can create an emergency health profile. The management console can be a Web-based application/administration tool accessible to subscribers over the Internet or other data network. A subscriber logs onto a website using a terminal  720  or  730  and enters the appropriate medical and contact information into a webpage, after which, the information is loaded into and stored in the central server  700 . Alternatively, the website or some other type of user interface, such as an interactive voice recognition (IVR) interface or a simple human operator interface can provide direct access to the central server  700 . After creating an emergency health profile, a subscriber can revisit the profile and update or make changes to the information stored therein at his or her discretion. This can be performed using the website or using the subscriber&#39;s mobile telephone via the agent resident thereon. This allows a subscriber&#39;s relevant medical and contact information to be as up-to-date as possible. Additionally, having personal access to one&#39;s medical information promotes consumer-driven healthcare and makes accessing one&#39;s medical information an easy task. Third parties, such as insurance companies and hospitals can also be given the authority to access and view or update a subscriber&#39;s medical and contact information, or even link their own databases and servers with the central server  700 . 
         [0038]    When a subscriber initiates a 911 call on his or her mobile telephone  600 , the 911 call is routed through the cell tower  610 , the MSC  620 , and to the central server  700 . A service set identifier (SSID), or other identifier capable of identifying the subscriber or the mobile telephone  600 , is also sent from the mobile telephone  600  at the same time the 911 call is initiated. Once the subscriber and/or mobile telephone  600  is authenticated using the SSID or other identifier, the central server  700  retrieves the emergency health profile of the calling subscriber. The central server  700  substantially simultaneously instructs the service provider that is operating MSC  620  to send a short message service (SMS) message containing the emergency health profile of the calling subscriber to PSAP  415   b , and to send an SMS, text, email, voice, or other type of message(s) to alert any designated contact person  710  stored in the subscriber&#39;s emergency health profile to the fact that a 911 call was initiated on the subscriber&#39;s behalf. 
         [0039]    In addition, the subscriber may be able to receive updates and notifications via an SMS message in case of catastrophic situations. These messages may be sent from the database of subscribers located on a central server  700  and routed through service provider that is operating the MSC  620  to all subscribers, or just a designated group of subscribers. For instance, if a catastrophe occurs in a specific region, the subscriber located in that region would be selected to receive an emergency notification. As well, the designated contact persons of the subscribers would also be able to receive updates or emergency notifications. 
         [0040]    It should be noted that prior to routing the 911 call to the PSAP  415   b , the methods discussed above regarding how to determine a mobile telephone&#39;s location can be used to choose the nearest PSAP. Alternatively, the agent discussed above, can be further adapted to determine the PSAP nearest to the mobile telephone  600 , to which the 911 call should be routed. Geographic areas can be divided into any one of a number of regions, based on various criteria. For example, a specified area of coverage for a PSAP may include an area within the borders of a town or county, whereas in an urban area, the specified area of coverage may be comprised of a predetermined number of blocks. This process of gleaning the relevant medical and contact information before the 911 call reaches a PSAP allows a PSAP operator to have all the necessary information to aid and direct emergency response personnel to the subscriber. In addition, the infrastructure and messaging functionality of existing service providers is better, and more efficiently utilized than in past emergency 911 call systems and architectures. 
         [0041]    In one embodiment  FIG. 8  provides a system in which a third party is used to retrieve both wireless location information (ALI) and PSAP location information in order to locate the nearest PSAP to the subscriber. The subscriber places a call in an emergency situation on their wireless communication device  600 , which is routed through one or more cellular towers  610 , a mobile switching center (MSC)  620  and directed to a call center  900 . The call center  900  may be human or database operated. The subscriber&#39;s ANI information is then forwarded to a central database  700  which can perform at least two functions of retrieving ALI information from a third party database  540  and implementing and managing all application modules for effecting the medical information service. Again, the subscriber may input and update this information through any terminal  720 ,  730 , interfaced with the Internet. 
         [0042]    After retrieving both the ALI and medical information through the central server  700 , the information is provided to the call center  900 . In this embodiment, the call center connects to a third party database  950  in order to find the nearest PSAP  800  to the location where the subscriber is making the call and connect to that PSAP  800 . The call center may then provide the location and medical information to the nearest PSAP  800 . In the instance where the call center is database operated, the medical and location information as well as the call would be immediately directed to the nearest PSAP through a VOIP or similar Internet type protocol. The call center may either maintain the connection with both the PSAP  800  and the subscriber. Alternatively, the call center may end the connection, allowing only the subscriber and the PSAP  800  to maintain their connection. The PSAP  800  may then perform its normal function of providing emergency assistance  420 ,  425 ,  430  to the subscriber as needed. This system improves upon previous systems, as it allows the PSAP centers to perform more efficiently because they have all the information necessary to provide a better emergency response. As well, it may allow for the PSAP to have lower call volume do to emergency being handled primarily by the call center and less time spent on emergency calls because more information regarding the subscriber is initially provided. 
         [0043]    In another embodiment,  FIG. 9  provides a system where the call center  900  and central server  700  provide the information necessary to locate the nearest PSAP  800  to the MSC  620 . For example, a call is made from a wireless device  600  and directed through a wireless tower  610  and an MSC  620  to the call center  900 . The ANI is then directed to the central server  700 , where the ALI information is retrieved. In this embodiment, a third party database  540  is utilized to retrieve the ALI information. Alternatively, the database  540  could be in connection with the centralized server, making the third party unnecessary. The information is routed through a centralized database, and back to the call center  900 . In this embodiment, the medical information and ALI are then sent to the MSC where the ALI is compared to a database of PSAPs. The nearest PSAP location is retrieved and the call is forwarded along with the subscriber&#39;s medical information, to the nearest PSAP  800  found through the MSC  620 . The MSC  620  may be in connection with its own database of PSAP&#39;s or utilize another party in order to retrieve this information. The call center may then maintain a connection with the subscriber and nearest PSAP operator, or end the connection, leaving only the subscriber and PSAP operator on the line. Again, the PSAP may then perform its usual functions of providing assistance, but in a more efficient manner. 
         [0044]      FIG. 10  provides an embodiment of the system in which the call is directed through the wireless tower  610  and the MSC  620  to the call center  900 . In this embodiment, the ANI information is then sent to the central server  700 , which connects to a third party database  540  in order to retrieve ALI information in order to locate the nearest PSAP  800  to the subscriber. In another embodiment, the database  540  may be in connection with the central server and call center, requiring no third party to be necessary. Once, the ALI information is retrieved by the central server  700 , it is compared with a database of PSAP in order to locate the nearest one to the location of the subscriber. The call center then receives the nearest PSAP  800  information along with the subscriber&#39;s medical information from the central server, the call center connects to that PSAP  800  through use of the MSC  620  and tower  610 . Again, the call center may remain connected to the caller and PSAP if desired, or end the connection after all information is forwarded to the PSAP. In another embodiment, the location of the PSAP may be retrieved through the third party database utilized to retrieve the ALI information. As disclosed above, the location of the nearest PSAP may also be retrieved through a database in connection with the MSC  620 . 
         [0045]    In a further embodiment,  FIG. 11  provides a system where the call center  900  performs all the functions necessary to locate and direct the subscriber&#39;s call and medical information to the nearest PSAP  800 . In this embodiment, the nearest PSAP may be located through a database in connection with the central server  700 . The call and the subscriber&#39;s medical information may then be directed to the nearest PSAP by the call center, bypassing a need for any outside party. In this embodiment, the central server  700  utilizes the ANI in order to retrieve the ALI information associated with the caller and compare it to a database of PSAP&#39;s. The call center may then connect the nearest PSAP  800  found through the central server  700 , to the subscriber and either stay on the line with the subscriber and PSAP operator, or end the connection, leaving only the subscriber and PSAP operator on the line. In the instance where the call center is database operated, the medical and location information as well as the call would be immediately directed to the nearest PSAP through a VOIP or similar type protocol. Again, the PSAP may then perform its usual functions of providing assistance, but in a more efficient manner. 
         [0046]    In another embodiment of the present invention, the agent or the mobile telephone itself can be coded with a subscriber&#39;s medical and contact information, bypassing the need to access the central server  700  during the processing of a 911 call. The medical and contact information can be encrypted and password protected as well. This further speeds the process of responding to the 911 call. Additionally, a subscriber can travel anywhere in the world and have access to his or her medical and contact information via his or her mobile telephone. In yet another embodiment of the present invention, the central server  700  as well as routing the emergency 911 call through the MSC  620  or other conventional service provider equipment can be bypassed. This is possible with networks that utilize advanced cell towers that have call routing functionality. 
         [0047]    It should be noted that although embodiments of the present invention discussed above are implemented in wireless emergency 911 networks, the present invention is also easily adaptable to landline emergency 911 networks. In addition, various embodiments of the present invention can be utilized on basic as well as E911 networks. The agent can also be installed in other mobile devices, as well as personal computers and voice over IP-based devices, allowing the same functionality discussed above to provided to non-mobile telephone subscribers. In fact, information other than or in addition to medical and contact information can be stored, maintained, and accessed for purposes such as Homeland Security.
