Abstract

A system for providing wireline telephone services to wireless subscribers utilizing a packet data network 100. The system includes a base station controller (BSC) 210 a base station controller gateway (BGW) 200 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) 500 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) 300 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) 410 and mobile switching center gateway (MGW) 400 are included to facilitate inter-system call handoffs into an existing circuit-switched wireless telephony network.
