ABSTRACT:
The present invention supports a message protocol on a wireless communication network to setup a shortened slot cycle operation for a mobile station. During wireless, packet-based communication, a mobile station can utilize a shortened slot cycle to increase the frequency a communication channel is monitored by a mobile station while in idle state. While this is advantageous to communication requiring a fast response, it increases power consumption and decreases battery charge time. Under present usage, the shortened slot cycle must be used by all mobile stations connected to the base transceiver whether required or not.To increase efficiency and avoid unnecessary power consumption, the invention allows only those mobile stations that require it to implement the shortened slot cycle. Signaling messages sent from the mobile station to the base station controller will initiate a shortened slot cycle only for that mobile station. Other mobile stations connected to the base transceiver operate without implementing the shortened slot cycle.
