Abstract
In code division multiple access communication systems, there are three levels for updating locations of dormant mobile stations (MSs) and setting up fast call. In sector and are levels, the dormant MS send a layer 2 message containing a message type and MS identifier to a base transceiver station (BTS). Since the message is associated with the sector where the MS is located, the network is aware of the MS's location from the updated location. The dormant MS sends to the BTS a reconnect message containing a message type and an MS identifier. The MS's dormant to active state transition is initiated by the MS. In the communication network, sub-packet zone ID is broadcasted in the overhead message. The MS reports its location change on R-CSCH and the network with the BSC level control can page the MS within the zone where the MS sends the report.
