A system and method for providing a simple, but effective technique for communicating overhead messages in a wireless communication system providing access to a decentralized network, while achieving bandwidth savings as well as minimizing power consumption. In one embodiment, a wireless base station which is connected to a decentralized network transmits a sequence of signatures for overhead messages to a mobile unit. The mobile unit wakes up receives the signatures and compares them to signatures stored at the mobile unit. If the signatures received by the mobile unit are different from the signatures stored at the mobile unit, the mobile unit stays awake to receive the overhead messages to be transmitted by the wireless base station. If the signatures received by the mobile unit are the same as the signatures stored at the mobile unit, the mobile unit may go back to sleep.

1. Field of the Invention
The invention relates in general to wireless communication systems, and more particularly, to overhead channel information delivery in wireless communication systems.
2. Description of the Related Art
FIG. 1 is a block diagram of a wireless communication system according to a preferred embodiment of the invention;
FIG. 2 shows a structure of a forward link of a wireless communication system in accordance with the invention;
FIG. 3 shows a process for communicating overhead messages using the structure of the forward link illustrated in FIG. 2;
FIG. 1 shows a system block diagram of a wireless communications system (CS or System) 200 according to the presently preferred embodiment of the invention. System 200 may include multiple base stations (BS) 210, 220 (only two shown) each of which can communicate wirelessly with a mobile unit (MU) 202 when MU 202 is within the geographic area covered by a base station. MU 212 includes terminal equipment 206 and mobile termination 204.
MU is used to refer to the composite entity consisting of the terminal equipment and the mobile termination. In this discussion, the term “mobile unit” is used to refer generally to the remote subscriber station for the purposes of this description. Note, however, that the mobile unit may be fixed in location. The mobile unit may be part of a multiple user concentrated subscriber system. The mobile unit may be used to carry voice, data, or a combination of signal types. The term “mobile unit” is a term of art and is not meant to limit the scope or function of the unit.
Base station 210, 220 includes base station transceiver subsystem (BTS) 212, 222 and radio link protocol and signaling manager (RSM) 214, 224. Base station is used to refer to the composite entity consisting of the BTS and the RSM.
