A selective call messaging system comprises a control point satellite uplink (24) for transmission of source information to a satellite (12), the source information having timing information, a base station (16) for receiving the source information from the satellite and for retransmitting the source information to a receiver 18. A synchronization controller 29 is coupled to the receiver 18 and remotely coupled to the control point satellite uplink. The synchronization controller comprises a decoder (40) for decoding the timing information received from the base station to provide actual timing information, an absolute time source (28) that generates a reference time, a comparator (42) for comparing the actual timing information with the reference time to provide an offset signal (44) and a transmitter for forwarding the offset signal to the control point satellite uplink to adjust timing information at the control point satellite uplink.

Method and apparatus for system synchronization in a messaging system

A selective call receiver is provided that is capable of receiving a transmitted fragmented message and displaying the fragmented message in at least two scripts. The transmitted fragmented message includes a plurality of sequentially ordered message packets each comprising an address and message data, at least one of the message packets having a script select character within the message data. The fragmented message is received by a receiver and passed to a circuit for displaying the fragmented message in the scripts, such that a first portion of the fragmented message is displayed in one of the scripts and a second portion of the fragmented message subsequent to the script select character is displayed in another of the scripts. A retrieval circuit is capable of retrieving a garbled message fragment if a sequentially prior message fragment containing the script select character is missing from the fragmented message. The retrieval circuit preferably includes an error indicator for providing a missing fragment signal indicative of the prior message fragment being missing, and a script select circuit for displaying the garbled message fragment in a selected one of the scripts.
