A system for providing wireline telephone services to wireless subscribers utilizing a packet data networkThe system includes a base station controller (BSC)a base station controller gateway (BGW)for providing client based services to mobile subscribers and providing protocol mapping between a mobile protocol and a packet data network protocol. The system further comprises a mobility gatekeeper (GK)for managing network mobility services for each wireless call including the establishment of a call control path and a speech path between said base station controller and a serving end office telephone point. The system also comprises a end office gateway (EOGW)for providing protocol conversion between the packet data network protocol and the end office point data protocol such that a wireless subscriber has access to all wireline services provided by the end office point. A mobile switching center (MSC)and mobile switching center gateway (MGW)are included to facilitate inter-system call handoffs into an existing circuit-switched wireless telephony network.

System, method, and computer program product for connectivity of wireless base station to PSTN via an IP data network

Methods and systems consistent with the present invention perform enhanced services for wireline and wireless subscribers in an integrated wireline and wireless switching system. The enhanced services may include, for example, group dialing plans, message waiting indicator activation, call forwarding, simultaneous ringing, call conferencing, calling line identification, automatic call back, automatic recall, speed dialing services, and/or any other services that may be provided by a switching system to wireless and/or wireline subscribers. When a calling wireline and/or wireless subscriber requests one or more of the enhanced services, the integrated wireline and wireless switching system determines the line types associated with the wireline and/or wireless devices of a called subscriber, and identifies references to one or more shared procedures for performing the enhanced services according to the determined line types without creating direct dependencies between wireline and wireless modules in the integrated wireline and wireless switching system. Finally, the integrated wireline and wireless switching system executes the identified procedures to perform the shared services.
