A multicast management mechanism for mobile networks. The mechanism proposes a multicast table approach to considerably reduce the number of short messages and multimedia messages sent to a service area, thereby reducing its paging cost. The multicast management mechanism for mobile networks includes the steps: establishing a VLR recorder table in a home location register (HLR), to record VLR addresses located by multicast users and the total number of multicast users in each VLR; and establishing LA tables, to record LA addresses in each VLR and the total number of multicast users in each LA.
