Method and apparatus for mapping an ip address to an MSISDN number within a service network

摘要

A system and method for associating an MSISDN of a mobile terminal (45) with a temporarily assigned IP address is disclosed. A first server (60) located within a wireless communications network generates and transmits a start packet to a service network responsive to an access request by a mobile terminal. The start packet includes the MSISDN of the mobile terminal (45) and an assigned IP address. A second server (75) within the service network extracts the MSISDN in the IP address from the received start packet and stores this information together within a database (80). When a service request is made by the mobile terminal (45) to a server (78) in the service network, the MSISDN may be determined from the database (80) and used to access user parameters in a user database.
