Abstract
In a method for allocating resources for a group call in a cluster system, when a group call is initiated, as cluster server counts the number of terminals under all MBSFN areas allocated and pre-allocated by each MCE for the group call, according to information about MBSFN areas allocated and pre-allocated by each MCE for the group call; when the group call is ongoing, re-counts the number of the terminals under all MBSFN areas allocated and pre-allocated by each MCE for the group call; upon determining that the number of the terminals under an MBSFN area changes from zero to non-zero, initiates a process of allocating resources for the group call under the MBSFN area; and upon determining that the number of the terminals under an MBSFN area changes from non-zero to zero, initiates a process of releasing resources allocated for the group call under the MBSFN area.
