Abstract
A method and corresponding apparatus and system of controlling access to communication services by a roaming wireless device are described. The method includes receiving a request for roaming wireless device service information related to a roaming user and determining which services the user has access to for the requesting system, if the user is determined to have access to the requesting system. The method also includes transmitting user service information concerning the services to which the user has access. The apparatus includes a memory, a communication system, and a processor. The memory stores: (1) user information including a class of service (COS) identifier and (2) COS restriction information. The processing system, coupled with the communication system and the memory, generates a reply message based on comparing information in a service request message received by the communication system with the stored information in the memory.
