Method for establishing a call rapidly in CDMA cluster communication system |
摘要 |
A method for establishing a call rapidly in a cluster communication system based on code division multiple access, comprising the following steps: a dispatching station server transmitting a normal group call request to a base station subsystem after receiving a normal group call request sent by a calling terminal; the each base station in a dispatching area allocating resource and establishing a forward-reverse traffic channel required by a normal group call service in the base station side after receiving the normal group call request; each sector of the base station in the dispatching area sending a broadcast channel assignment message in a form of broadcast message to the terminals in an idle state in the sector in a forward control channel; the terminals in the sector comparing a broadcast address with a group identification stored, if matching, the terminal establishing each service channel in the side of the terminal in the called state according to the broadcast channel assignment message received; if the broadcast address not matching the group identification stored, the terminal discarding the broadcast channel assignment message. |
