Abstract: A system, wireless device (306) and method determine that a wireless device (306) is detecting a triggering event. The triggering event includes detecting a WLAN border cell (210), detecting a first signal from an egress portal (302), or detecting a degradation in signal quality. The wireless device (306) then detects at least one signal from an egress portal (302), determines that the wireless device (306) 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 (302), initiates a registration sequence with the second wireless communication system in response to determining that the wireless device (306) 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.

Abstract: An apparatus and method for implementing calling restrictions between communication networks includes a first step of defining call control parameters in a repository. A next step includes initiating a call from the first network via a gateway for a target identifier in the second network. A next step includes making a query to download a text record of the call control parameters from the repository. A next step includes downloading the set of call control parameters in a text record by the gateway. A next step includes restricting the call from the first network to the second network by the gateway in accordance with the set of call control parameters.

Abstract: 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).

Abstract: A method and apparatus remotely retrieves messages intended for an acknowledge-back pager (400, 700) in a communication system including a fixed portion (100) and the pager (400, 700). The communication system has provisions for interconnection with a user by telephone. The fixed portion (100) accepts (502) a selective call origination from a caller, including a message intended for the pager (400, 700) and sends (504) the message to the pager (400, 700) in response. The pager (400, 700) stores (506) the message within a pager memory (418). Thereafter the fixed portion (100) accepts (508) a selective call origination from the user, including a predetermined retrieval code associated with the pager (400, 700). The fixed portion (100) sends (510) a predetermined retrieval command to the pager (400, 700) in response, and the pager (400, 700) retrieves the message from the pager memory (418) in response.
