    Abstract: A selective call receiver includes a receiver (103), a controller (105), and a display (113) for presenting a recovered source document. The receiver (103) provides a received paging message that was generated from the facsimile message of the original source document (208). The received paging message is interpreted and decoded by the controller (105). Using the display (113), a decoded scan line compressed document (1101) is presented in a format tht substantially resembles the facsimile message of the original source document (1100).

    Abstract: A message transmission system (100) and method for providing flexible roaming to a receiving device (126) which includes a code memory (422) which stores addresses of a first type (1202) to enable reception of messages within a local geographic area, and an address of a second type (1214) to enable reception of the messages within a different geographic area. The message transmission system (100) includes a transmitter (SSID1) which transmits the addresses of the first type with the messages associated therewith within the local geographic area, and a controller (204) which controls conversion of the addresses of the first type to the address of the second type, and transfer of the address of the second type with the messages associated with the addresses of the first type to a transmitter (SSID2-SSID5) which transmits the address of the second type with the messages associated therewith to the receiving device when operating within the different geographic area.

    Abstract: The radio communication system (100) comprises a transmitter (104) that transmit s information during the predetermined time period assigned to at least one radio receiver (106). A monitoring device m onitors a level of traffic associated with each of the predetermined time periods and a measuring device measures a level of traffi c associated with the radio receiver (106) over the assigned predetermined time period. An identifying device, coupled to the me asuring device, identifies if the level of traffic associated with the radio receiver (106) exceeds a predetermined threshold value during the assigned predetermined time period. A generator, coupled to the measuring device and to the identifying device gener ates a control signal, and the transmitter transmits the control signal to the radio receiver (106) for reassigning the rad io receiver to another of the plurality of predetermined time periods.

    Abstract: The present invention comprises a method for compressing a plurality of voice signals within a voice communication resource (see FIG. 6) having a given bandwidth within a voice communication system (100). The method comprises the steps of subchanneling the voice communication resource into a plurality of subchannels (441, 442, 443), placing a pair of the plurality of voice signals (401, 402) on a subchannel (441); modulating the pair of the plurality of voice signals (401, 402) about a pilot signal (581) within the subchannel (441) using single sideband modulation; and compressing the time of each of the voice signals (401, 402) within the plurality of subchannels (441, 442, 443), wherein these step provide a compressed voice signal.

    Abstract: Network roaming information (NRI), which comprises identifies a network (200) and a service area (210) within the network (200), a receiver address, is transmitted in a network (200) during a predetermined number of time slots of a signal, whereby the signal is transmitted in consecutive cycles, each cycle comprising a plurality of consecutive time slots. The placement of the NRI in the transmitted signal is made to be predicted by a receiver so that the receiver can compute an expected time slot location of a NRI to be compared with a stored NRI. The placement of the NRI is made according to an algebraic relationship between moduloN of the transmission frequency of the signal, moduloN of the order of the cycle, and moduloN of a portion of the NRI, wherein N is an integer.

    Abstract: A selective call receiver (106) receives one or more message packets of a transmitted fragmented message, where each of the one or more message packets includes an address (1605) and message data (1610), and the message data (1610) includes an indication (1702) of whether more message packets are to be received for the fragmented message. The selective call receiver (106) receives an address of each message packet, and then correlates (2908) the address to one or more predetermined addresses. After a successful correlation (2908), the selective call receiver (106) decodes the message data (1610) of each message packet, and then successively stores (2928, 2936, 2942) the decoded message data (1610) to reconstruct the fragmented message. The selective call receiver (106) determines that the fragmented message is completely reconstructed after detection (2918) in the decoded message data (1610) an indication (1702) that no more message packets are to be received for the fragmented message.
