ABSTRACT:
A method and apparatus for offering wireless telecommunication service. A switch such as an automatic Private Branch Exchange (PBX), equipped to communicate with Integrated Services Digital Network (ISDN) stations sends ISDN signaling messages to and receives ISDN signaling messages from a protocol converter. The protocol converter, which also communicates with a wireless cell site, converts messages between the ISDN protocol and a protocol for communicating with the wireless cell site. The cell site sets up wireless connections to a mobile station, essentially in its prior art mode, and the PBX sets up connections to the cell site essentially in its prior art ISDN station control mode. The PBX is connected to a class 5 (central office) telecommunications switching system for establishing connections between the public switched telephone network and the PBX, or between outlets of the PBX for a call between wireless stations.
