Abstract:
1. In a wireless communication system including a plurality of wireless transmit/receive units (WTRUs), a method of paging a plurality of WTRU users belonging to a paging group, the method comprising: (a) activating a point-to-multipoint (PtM) service for the WTRUs within a PtM service user group; (b) assigning a new temporary user specific identity to each of the WTRUs in response to activating the PtM service to synchronize WTRU specific paging occasions with WTRU user group paging occasions such that each WTRU specific paging occasion occurs at the same time as a corresponding WTRU user group paging occasion; (c) determining whether a paging occasion is associated with a PtM service or a point-to-point (PtP) service; and (d) if the paging occasion is determined to be associated with a PtM service and a predetermined maximum number of users associated with the paging occasion is exceeded, generating a plurality of subgroup paging identities, wherein each subgroup paging identity is associated with a particular paging subgroup within the PtM service user group, a particular paging channel and a particular paging occasion.
