A system, wireless device () and method determine that a wireless device () is detecting a triggering event. The triggering event includes detecting a WLAN border cell (), detecting a first signal from an egress portal (), or detecting a degradation in signal quality. The wireless device () then detects at least one signal from an egress portal (), determines that the wireless device () is moving from the coverage area of a first communications system to the coverage area of a second communications system according to the order of signals received from the egress portal (), initiates a registration sequence with the second wireless communication system in response to determining that the wireless device () is moving from the coverage area of the first communications system to the coverage area of the second communications system, and conducts present and subsequent calls via the second wireless communication system.

System and method to improve WLAN handover behavior at entry/exit points

A communication system (100) providing analog message re-transmission on demand comprises a base station (114) and at least one portable communication transceiver (118). The base station (114) transmits an address (414) identifying the portable communication transceiver (118) to which a voice message is directed, and a session number (415) modulated in a first modulation format and a compressed analog message (418) representing the voice message modulated in a second modulation format. When the signal quality of the voice message played back in the portable communication transceiver (118) is perceived by the user to be unintelligible, the user can receive from the base station (114) a re-transmission of the compressed analog message (418) by generating a request for re-transmission of the compressed analog message (418).
