Abstract
The method of present invention is used for addressing a broadcast message in a trunking system, in which said trunking communication system includes a base station and mobile stations. This method includes the following steps: adding a new index of trunking broadcast time slots, with all the mobile stations that support boundless capacity group call service monitoring these trunking broadcast time slots; the base station transmitting the paging message of the boundless capacity group call in the trunking broadcast time slot; and using the group identification as the broadcast address, allowing addressing to the group identification and not a single mobile station. The method of present invention efficiently solves the problem of paging channel capacity limitations of the boundless capacity group call service supported by CDMA trunking telecommunication systems, and greatly shortens the time of group call connection.
