Abstract: In an embodiment of the method of handling mobile station identifiers, at least one network element that used entire mobile station identifiers in performing packet data session handling functions is programmed to use less than the entire mobile station identifiers.

Abstract: A method of communication to at least one wireless unit originating an emergency call. The method includes the step of receiving one or more routing tags associated with a wireless unit originating a “9-1-1” call. A routing tag may comprise, for example, a string of numbers corresponding with Emergency Service Routing Digits (“ESRD”) and/or an Emergency Service Routing Key (“ESRK”). In addition to the routing tag, a mobile equipment identification number (“MEIN”) and/or a paging identity (“PGID”) may also be received by a database accessible by wireless network infrastructure elements, such as a mobile switching center (“MSC”), as well as the emergency call center, including the local public service answering point, for example. In response to this receiving step, at least one unique identifier (e.g., unique call back number) may be generated. This unique identifier may be a dialable number to enable the emergency call center to call back the wireless unit originating the “9-1-1” call.

Abstract: A method of communication to at least one wireless unit originating an emergency call. The method includes the step of receiving at least one tag identifier in response to the emergency call originating from the at least one wireless unit. Once the tag identifier is received, a wireless call back number corresponding with the at least one tag identifier may be transmitted. A public service answering point emergency call register (“PSAP-ECR”) may receive the at least one tag identifier and transmits the wireless call back number over a D interface.

Abstract: In an embodiment of the method of handling mobile station identifiers, at least one network element that used entire mobile station identifiers in performing packet data session handling functions is programmed to use less than the entire mobile station identifiers.

Abstract: In one embodiment, communication from a user device is recognized as a service request, and in response, a surrogate home system is invoked without accessing a home system for the user device. The surrogate home system is configured to handle connecting the user device with a provider of the service requested.

Abstract: A system is provided to allow a network to obtain the location of a mobile station (e.g. mobile phone) having AGPS/AFLT CDMA capability during an emergency call—without the use of the MPCAP parameter. The MPC invokes the PDE, which is IS-801 AGPS capable, without the MPCAP parameter. The PDE then queries the mobile for its geolocation capabilities, in the absence of the MPCAP parameter. This allows a visited network (e.g. the network in which the mobile station is roaming) to obtain a position (based on IS-801 AGPS/AFLT) for roaming mobile stations that are CDMA AGPS/AFLT capable—without the use of the network MPCAP parameter.

Abstract: A call is indirectly established by triggering a call register to request a mobile switching center, associated with a mobile station, to establish a call between the mobile station and a second party.

Abstract: A method is provided for conducting an emergency communication session with public safety answering point (54) over a public switched telephone network (50).

In an embodiment, the current location information may indicate current access networks and/or current destination addresses associated with the current location. The global location register can be used to respond to queries regarding subscribers' current locations or to route calls to subscribers in real-time.

Abstract: A GPRS interworking and interoperability function (IIF) is interposed between a serving GSM/GPRS wireless system and a second wireless system of a different technology family to allow a mobile station homed to the second wireless system to operate in the GSM/GPRS system. The IIF executes or emulates the behavior of a GPRS HLR when communicating with the GSM/GPRS system, and executes or emulates the behavior of an MSC/VLR of the home system technology family when communicating with the home system. When a mobile station registers in the serving system, the MSC/VLR portion of the IIF transmits a registration notification message to the home system HLR specifying the address of an associated SGSN as though it were an MSC.

Abstract: Disclosed is a method and apparatus for providing authentication for a subscriber of a wireless communication system employing one type of authentication technology roaming into a wireless communication system employing a second type of authentication technology. The method and apparatus involves transmitting (or receiving) a first message to a first system comprising a mobile identifier for a subscriber of the first and a second system indicator indicating that the subscriber is attempting to gain access to a second system that uses an authentication process different than an authentication process used by the first system; determining shared secret data for the subscriber using the mobile identifier; receiving (or transmitting) a second message from the first system having shared secret data associated with the subscriber; generating an expected response to a unique challenge using the shared secret data and an encryption algorithm, and transmitting the expected response to the second system.

Abstract: In the method of subscriber initiated porting of a wireless number for a mobile station, a new service provider receives a porting request sent by a subscriber, and sends a profile request to a current service provider of the subscriber in response to the porting request. The profile request requests profile information on the subscriber. Subsequently, the new service provider receives the profile information for the subscriber, and sends a porting complete notification to the subscriber.

Abstract: A wireless voice and data communication system facilitates providing packet data services to mobile subscribers even when they roam into areas that are served by a system that operates using a protocol different than the subscriber's home system protocol. In one example, a subscriber profile including appropriate authorization for packet data services that conforms to a GSM/GPRS protocol is mapped from a home location register (HLR) that uses the GSM protocol to a visitor location register that uses a CDMA/ANSI-41 protocol so that the GSM mobile subscriber obtains packet data services through provider system that uses the CDMA/ANSI-41 protocol.
