Claim:
1. A method for allocating resources for a group call in a cluster system, comprising: when the group call is initiated, a cluster server counting the number of terminals under all multicast broadcast single frequency network (MBSFN) areas allocated and pre-allocated for the group call by each multi-cell/multicast coordination entity (MCE), according to information about the MBSFN areas allocated and pre-allocated by each MCE for the group call; when the group call is ongoing, when a terminal delays to access the group call, a terminal in a group call listening state exits from the group call, or a terminal in the group call listening state is moving under different MBSFN areas, the cluster server re-counting the number of terminals under all the MBSFN areas allocated and pre-allocated by each MCE for the group call; and as regards each MBSFN area, if it is determined that the number of terminals under the MBSFN area changes from zero to non-zero, the cluster server initiating a process of allocating resources for the group call under the MBSFN area; and if it is determined that the number of terminals under the MBSFN area changes from non-zero to zero, the cluster server initiating a process of releasing resources allocated for the group call under the MBSFN area.
