Abstract: A wireless communication system (200, 300, 400, 500) mitigates the effects o f excess timing delay caused by varying lengths of communication paths. In one general implementation, a transition communication path (206, 323, 329) is used to transfer a time-advanced version of a timing reference signal so tha t the cumulative time delay at a transition cell (209, 325, 331) is reduced. I n another general implementation, the timing reference signal is time-advanced in all communication paths (403-411), and selected communication paths (403- 407) include a time delay means (423-427, 503-507) such that the cumulative time delay at an area (421) near a target coverage area (130) is reduced. By reducing the cumulative time delay at the area (421) near the target coverag e area (130), a hand-off of a communication of a mobile station (128) into the target coverage area (130) can be performed.

Abstract: The dual mode communication network comprises a first communication system having a frame structure and a first traffic channel protocol and a second communication system having the frame structure and a second traffic channel protocol. In the network, only one of the first and second traffic channel protocols supports forward error correction coding.

Abstract: A base-station (100) pages a remotely located portable (110) at a first RF power level on a broadcast channel and, if the portable (110) does not respond, the base-station (100) attempts to page the portable (110) at a second, higher RF power level on a high power paging channel. The high power page includes a switching circuit identification number that, if called by the subscriber using either the portable (110) or a fixed-telephone (130), switches switching circuitry (200) accordingly to establish communication to the originator.
