ABSTRACT:
A paging system has a signal for transmitting a variable amount of messages to paging receivers. The signal has a synchronization signal, an address field, an information and a boundary signal indicative of the boundary between the address field and the information field. Each message has addresses which are included within the address field and may have message information which is included in the information field. The information field includes two portions, a first portion having a plurality of packets for holding a predetermined amount of information and a second portion for holding a variable amount of information. If the information associated with a messasge is less than the predetermined amount, the message information is stored in the first portion of the information field. If the message information is greater than the predetermined amount, it is stored in the first and second portions of information field and a vector signal indicating the location of the message information is stored in the first information field. The first portion further includes at least one check signal which provides parity for a plurality of packets. Methods of generating the message signal, receiving a message, displaying a message and conserving power during the reception of a message are described.
