Abstract
The present invention discloses a group call method, device and terminal, belonging to the field of communications technologies. The method includes: calculating, according to the load of a RAN device, the number of subgroups in a group maintained by the RAN device; and send a paging message carrying relevant information of the number of the subgroups, so that a terminal receiving the paging message determines, according to relevant information of the number of the subgroups, whether to respond to the paging message. The device is a RAN device or a CN device. The terminal includes a receiving module and a processing module. In the present invention, the number of paging groups and an in-group terminal being paged are determined dynamically without requiring a core network to maintain subgroup information, thereby greatly saving subgroup maintaining resources as well as signaling and processing resources.
