METHOD FOR ALLOCATING IDENTIFIER, METHOD FOR MULTICASTING, AND COMMUNICATION EQUIPMENT

摘要

The embodiments of the present invention provide a method for allocating an identification using an access network grouping scheme, a group paging method, and corresponding communication device. The ID allocating method comprises: receiving a group ID of a group of group-paged objects allocated by a core network device for a terminal device, wherein the group of group-paged objects comprises one or more subgroups; allocating a device ID or a user ID to the terminal device, wherein the device ID or the user ID comprises information of a subgroup ID of a subgroup to which the terminal device belongs; and sending the allocated device ID or user ID to the terminal device. In the embodiment of the present invention, not only a grouping is carried out in the core network hierarchy, but also the terminals in each cell are further grouped in the access network hierarchy, so that the number of terminals in the subgroup is appropriate, and the resources are allocated more flexibly and reasonably.
