Abstract
The invention relates to a method for splicing the called time of trunked group calls, which is used for trunking communication systems with a code division multiple access (CDMA) system. The method comprises a step 1 as follows: after a base station controller receives a call starting message initiated by a caller and before the base station controller allocates radio resources, a broadcast message is sent to ask an intragroup called party to enter a non-time-slot mode monitoring-paging channel, and the intragroup called party enters the non-time-slot mode monitoring-paging channel after receiving the broadcast message, so as to shorten the called splicing time of trunked group calls. As the method can ask a called terminal to enter the non-time-slot mode monitoring-paging channel in advance, the called terminal can receive the broadcast message with resources as soon as possible, so as to enter group call service after channel allocation, and then the called splicing time of trunkedgroup calls is shortened.
