Abstract
A communication system (105) provides roaming instructions within a signal having frames of data. The communication system (105) includes a message transmission device (110) for batching information into a frame of data and transmitting, within a predetermined geographic area, the information on a radio communication channel. The frame includes at least frame offset information for reception by a data communication receiver (115) located within the predetermined geographic area for receiving the information. The data communication receiver (115) stores a base frame number associated with a base frame during which the data communication receiver (115) is assigned to wake for message reception. The frame offset information is indicative of a substitute frame that is relative to the base frame. The data communication receiver (115) is to wake for message reception thereafter in the substitute frame rather than the base frame.
