Abstract
The present invention discloses a method for quickly building calls in a mobile communication system. The method is characterized in that when a user presses a PTT key, a base station subsystem directly sends out a base station response instruction, and a terminal receives two continuous good frames; a mobile station sends out mobile station response instructions to the base station subsystem in a reverse service channel; after the base station subsystem succeeds in trapping the mobile station response instructions which are sent out by the mobile station in the reverse service channel, the base station subsystem sends out a confirmation so that the mobile station stops sending out the mobile station response instructions; thus, an air link is established, and signaling handshaking is completed ahead of schedule. Compared with the prior art, the present invention reduces the building time of the service channel, accelerates call establishment and meets the demand of fast response of cluster service.
