Abstract

The Advanced Intelligent Network (AIN) wireline system connects to and controls processing of calls to a Personal Communication Service subscriber'"'"'s wireless handset via a home base station or a wireless communication network. Depending on its current location, the subscriber'"'"'s handset automatically registers with the base station or with a mobility controller of the wireless network. A new registration with the base station when the handset comes within range causes that station to update the subscriber'"'"'s home location register in a central data base of the AIN. Similarly, when a handset first registers with a mobility controller, that controller updates the subscriber'"'"'s home location register in the central data base of the AIN. In response to calls directed to the subscriber, the AIN accesses the home location register to determine the current location where the handset is registered. The AIN then uses that data to route the call to the current location. In response to calls from the handset, the central data base provides instruction data to the land line network and/or a mobility controller to extend a requested special service to the calling subscriber.
