MULTICAST SERVICE ENABLE AND USER EQUIPMENT BATTERY SAVING METHOD, ESPECIALLY CONCERNED WITH PRESERVING WIRELESS RESOURCES AND EXTENDING A BATERRY LIFE BY SUPPLYING TO A USER A MULTICAST OR BROADCAST SERVICE EFFCIENTLY

摘要

PURPOSE: A multicast service enable and user equipment battery saving method is provided to effectively transmit a multicast service and a broadcast service to a user. CONSTITUTION: A network determines each group and member UEs(User Equipments) related to the groups(202). The network determines all groups related with one UE(204), and schedules group identifiers and related pointers within a paging window such that each UE can access the one paging window(206). The network determines whether more paging windows are required for each UE(208). If not, the network determines whether a random scheduling collision exists between data messages for a specific UE(212). If so(214), the network reschedules the data messages(216). The network determines whether a data message collision still exists(218). If so, the network schedules a copied data message(220).
