PAGING SYSTEM EMPLOYING DESIGNATED BATCH INFORMATION SERVICE DATA MESSAGE TRANSMISSION |
摘要 |
A paging system which provides both individual and information services includes a transmitter for transmitting page call address and data periodically in batches, and a population of battery saver paging receivers for receiving the transmitted call information. Each transmission batch comprises a synchronization code followed by a predetermined plurality of sequential frames. Each subscribing receiver searches for its individual service address in a first designated frame of each batch of a transmission period, and in addition, searches for its information service address in a second designated frame of a designated batch of a transmission period. Individual and information service data messages are obtained from frames subsequent the frame at which their respective address is found. |
