<p>The present disclosure provides a method and apparatus for transmitting a Broadcast Channel Assignment Message (BCAM) in a trunking system and a system for transceiving a BCAM in a trunking system. The method includes the following steps that: a base station side constructs a BCAM without resources, generates a hash time slot list according to an acquired International Mobile Subscriber Identity (IMSI) list, determines a paging time slot monitored by a called terminal according to the hash time slot list, and places the BCAM without resources to a queue corresponding to the paging time slot monitored by the called terminal; the base station side sends the BCAM without the resources in the queue to the called terminal, which enters a non-time-slot monitor mode after demodulating the BCAM without resources; and the base station side constructs a BCAM with resources and then sends the BCAM with resources to the called terminal in the last paging time slot in a time slot period. The present disclosure effectively reduces the load of a paging channel, and guarantees the quick access of a called terminal supporting a negative time slot while avoiding the call for a called terminal supporting a positive time slot being missed.</p> |
