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.

Abstract: A satellite based paging communication system comprises at least one satellite (102) capable of communicating the paging information to at least one terrestrial receiver (110, 116, 126) some of which are capable of transmitting an acknowledge signal (127) so that message reception may be verified and satellite traffic controlled.

Abstract: A portable communications receiver includes a receiver for receiving and detecting periodically transmitted selective call paging signals and data signals. In response to the selective call paging signal, a decoder generates control signals which allow storage of the data signals in a memory, and a display of the latest stored signals. A graphic characterization is provided for depicting the moving object. The effect of movement of the object is generated as the data signals are periodically updated and displayed. By individually animating the graphic characterization between updates, the effect of movement is enhanced. The data signals are periodically updated and include an absolute position signal for depicting an absolute position of the moving object. The data signals further include a relative position signal for depicting a relative position of the moving object relative to another moving object.

Abstract: A satellite based simulcast paging communication system comprises a plurality of terrestrial stations capable of simulcasting the paging information with at least one satellite for reception by one or more of a plurality of terrestrial receivers (pagers). Also included is at least one control station for determining where and how to deliver the paging information to achieve simulcast transmission.

Abstract: 2050892 9100655 PCTABS00003 This invention relates to selective call receivers (11), such as paging receivers, for receiving modulated data signals having a variable bit rate. A band pass filter (26), particularly an I. F. filter, is provided having an adjustable bandwidth. The bandwidth of the filter is adjusted in accordance with a code in the received signal which indicates the bit rate.

Abstract: A transmitter, having controllable transmission functions is described for transmitting coded message signals to a plurality of portable communications receivers, the coded message signals including and message information interleaved with transmitter control signals synchornized with the message information. The transmitter includes a receiving section for receiving the coded message signals from an input source for transmission. A decoder which couples to the receiving section decodes the synchronized transmitter control signals to derive transmission control signals. A transmitter section, responsive to the transmission control signals, transmits the coded message signals. Additional transmission control signals may also be derived from one or more receiver control signals embedded in the coded message signals.
