  • Patent number: 5710976
    Abstract: A method and apparatus is used for transmitting an outbound message in a two-way messaging system having a plurality of cells employing frequency reuse. The outbound message is transmitted to a selective call transceiver (122) utilizing a first frequency reuse plan (312). The two-way messaging system awaits a positive acknowledgment (316, 318) from the selective call transceiver (122) confirming that the outbound message was received with an acceptable quality. The two-way messaging system retransmits the outbound message to the selective call transceiver (122) utilizing a second frequency reuse plan (332), in response to receiving a negative acknowledgment and also in response to failing to receive any acknowledgment within a predetermined time after transmitting the outbound message.

  • Patent number: 5694454
    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).
