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 present invention provides a method and apparatus for restricting call terminations for a roaming mobile unit. A serving MSC, which is an MSC providing call processing a mobile unit that is not the home MSC of the mobile unit, sends a registration notification request to the home location register (HLR). The HLR retrieves the termination access code parameter from the HLR and sends it to the serving MSC. The termination access code parameter includes a value that indicates if the mobile unit is allowed to roamer port calls. The parameter is stored at a VLR associated with the serving MSC. When a call request comes in to the serving MSC and requests a roamer port call with the mobile unit, the serving MSC checks the value of the termination restriction code to determine if it should terminate, or complete, the call.

Abstract: A system for providing location based service telephone call to wireless subscribers. The system of the present invention provides processes for receiving location data about a wireless subscriber telephone and using the information to find the telephone number of the nearest service provider. The wireless subscriber telephone set can then be connected to the nearest service provider. It is also possible to a plurality of different location identifiers to determine the nearest service provider. In performing a look-up, the list can be used on a priority basis to determine the nearest service provider.
