ABSTRACT:
The present invention allows for the detection of data contained in transmitted messages (e.g., page messages) at a selected early point in the receiving and decoding process. By forming, at that point, a received data vector (RDV) from the data corresponding to a received message, and by comparing the RDV with one or more test data vectors (TDVs) representing selected relevant or irrelevant data contained in transmitted messages, the receiver (e.g., mobile station) can determine whether the received message contains relevant data which should be fully decoded or irrelevant data which does not need to be fully decoded. In this manner, substantial processing and power savings can be achieved in the receiver.
