Selective call receiver with a universal synchronization code operating mode

A selective call receiver for receiving a signal comprising batches, each batch comprising a plurality of frames, each frame comprising one of a number of synchronization codes, the selective call receiver comprising:

• receiver circuitry for receiving the signal;
• memory means for storing a plurality of addresses assigned to the selective call receiver and for storing a plurality of frame bytes, each of the plurality of frame bytes being predetermined and corresponding to one of the plurality of addresses;
• synchronization code detection means coupled to the receiver circuitry for detecting the one of a number of predetermined synchronization codes;
• and
• control means coupled to the memory means and the synchronization code detection means for combining ones of the plurality of frame bytes in a predetermined manner to form a frame process byte comprising a plurality of bits, each of the plurality of bits corresponding to one of the plurality of frames and having a binary value, the ones of the plurality of frame bytes determined in response to the one of a number of predetermined synchronization codes;
• and
• power conservation means coupled to the control means for activating or deactivating the receiver circuitry during reception of one of the plurality of frames in response to the binary value of the one of the plurality of bits.

In a communication system communicating a signal having a plurality of batches, each of the plurality of batches having either a first or second synchronization code signal, each of the plurality of batches further having at least a first frame and a second frame, wherein the communication system transmits

• a first batch of the plurality of batches having the first synchronization code signal and the first frame of the first batch having a first message signal beginning therein and
• a second batch of the plurality of batches having the second synchronization code signal and the second frame of the second batch having a second message signal beginning therein, a method for receiving the signal comprising the steps of:
• (a) receiving either the first predetermined synchronization code or the second predetermined synchronization code in both the first and second batches;
• (b) receiving the first frames in both the first and second batches in response to said step (a) of receiving;
• and
• (c) receiving the second frames in both the first and second batches in response to said step (a) of receiving.
