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. Thereafter, the unique identifier may be transmitted back to the MSC, along with the emergency call center, for example. Consequently, an emergency call back may be launched by the emergency call center using the unique identifier to reach the MSC generally, and more particularly, the wireless unit originating the "9-1-1" call.

En una modalidad el método para manejar identificadores de estación móvil, al menos un elemento de red (36, 30) que utilizó identificadores de estación móvil completos al realizar funciones de manejo de sesión de datos de paquete se programa para utilizar menos que los identificadores de estación móvil completos.
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:
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:
The method for transferring data according to the present invention sends da ta as part of a first type of permanent identifier associated with an end user in a communication system. The first type of permanent identifier is sent along with a second type of permanent identifier, also, associated with the end user, during a communication procedure prior to establishing a traffic channel in the communication system. Besides the data, the permanent identifier of the first type include s routing information to a home system forming part of the communication system. The e nd user also stores the sent permanent identifier of the first type, and in response to receiving the stored permanent identifier of the first type in a communication, will generate a new permanent identifier of the first type. In this manner, a destination entity receiving the permanent identifiers of the first type from the home system, can request mo re data from the end user by having a received permanent identifier of the first typ e re-sent to the end user.
Abstract:
The method for transferring data sends the data as part of the expanded portion of an expanded permanent identifier which is associated with an end user in a communication system. The expanded permanent identifier is sent along with another permanent identifier, also associated with the end user, during a communication procedure prior to establishing a traffic channel in the communication system. The other permanent identifier includes routing information to a home system forming part of the communication system. Based at least in part on recognizing the other permanent identifier, a home system sends at least the expanded permanent identifier to a destination entity. The destination entity extracts the data from the expanded permanent identifier. In this manner, a traffic channel does not need to be established to transmit the data.
Abstract:
In an embodiment of the method of handling mobile station identifiers, at least one network element (36, 30) 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 aspect of the instant invention, a method is provided for controlling a communications system. The method comprises storing a 15-digit universal identifier in a mobile device in two locations ordinarily used to store a 15-digit MIN-based _IMSI and a 15-digit true IMSI. The universal identifier is comprised of a 10-digit Mobile Identification Number (MIN) and a 5-digit Home Network Identifier (HNI), which is comprised of a 3-digit Mobile Country Code (MCC) and a 2-digit Mobile Network Code (MNC). Generally, the communications system uses the universal identifier to control international roaming. However, the mobile device transmits only the 10-digit MIN in response to the mobile device being within a home network. To form the 15-digit universal identifier, the home network appends its HNI to the received MIN. When the mobile device is outside of its home network, the mobile device transmits the entire 15-digit universal identifier.
Abstract:
A method is provided for controllably migrating a wireless network from MIN based operation to IMSI based operation. The method comprises implementing changes that affect inter-network operations during a first phase of the migration. Remaining changes, including changes that affect intra-network operations are implemented during a second phase of the migration.
