Overhead message update with decentralized control
First Claim
1. A method for communicating with a mobile station by way of a forward channel in a wireless communication system, the method comprising:
- receiving a message capsule over the forward channel;
calculating a signature from the message capsule at the mobile station; and
comparing the signature with one or more signatures previously stored at the mobile station.

Abstract
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.

2. An apparatus for communicating with a mobile station by way of a forward channel in a wireless communication system, comprising:
a base station configured to; transmit a message capsule over the forward channel; generate a signature for the message capsule, the signature being generated by hashing the message capsule, wherein the hashing comprises hashing the message capsule to generate a first hash and rehashing the message capsule if the first hash of the message matches a signature of a previous message capsule; and transmit a signature in a separate signature capsule over the forward channel. - View Dependent Claims (3, 4, 5, 6, 7)
