Abstract
A paging receiver receives a message signal having an address field and a data field. The message has at least one address within the address field and a plurality of packets in the data field. The data packets contain a predetermined amount of information. A method for conserving power during reception of a message signal having an address field comprising a number of addresses involves entering the power conserving mode of operation after attempting to correlate a predetermined number of addresses with the paging receiver's address, where the predetermined number is less than the number of addresses in the address field. In addition, message information may be included within a plurality of packets by several methods including placing a corresponding plurality of addresses in the address field, each address indicating the occurrence of message information, or by indicating in one packet that information follows in a subsequent packet. Use of the second method provides for placing of tone only messages in positions left vacant in the address field by the subsequent data packets. Additionally, the invention provides for varying the size of the address field with a boundary signal.
