CALL SET-UP FOR FIXED WIRELESS COMMUNICATIONS SYSTEM

摘要

A fixed wireless communication system (100) is a hybrid of a fixed wire-line telephone system and a conventional cellular radio system. In particular, this fixed wireless telephone system (100) provides an instant communication link between a user's fixed wireless terminal (101) and a wire line communication system (105), allowing a user to dial another user's number as well as receive call progress tones such as the dial tone. This link is established by detecting (403) an off hook signal at the communication device, transmitting (405) a call set-up request with a "ghost" telephone number over the conventional cellular system, and recognising (411) the "ghost" telephone number, requesting (413), responsive thereto, an audio link on the wire line communication system (105), and linking (415) the audio link on the wire line communication system with the first communication device over the conventional cellular radio communication system.
