发明名称 Selective Call Receiver with a Universal Synchronization Code Operating Mode
摘要 A selective call receiver (30) for receiving selective call signals in a universal synchronization code operating mode receives signals having the conventional POCSAG sync code and signals having dual sync codes and decodes the signals appropriately to recover personal and information services messages. Whether the receiver (30) is operating in a conventional POCSAG system or a dual sync code system, the receiver (30) conserves battery power by activating the high battery draining receiver circuit (34) only during frames (106) of the signal (100) wherein personal message addresses or database information is likely to appear. The frames (106) where the personal message addresses are likely to appear and where the database information appear are indicated by a frame byte stored in a memory (48) with the corresponding address.
