Abstract

A wireless communication method and system for efficiently managing paging windows and data messages. The wireless communication system includes at last one network and a plurality of user equipments (UEs). The network maintains a memory that lists UE group identifiers, UE members associated with the UE group identifiers, and paging windows that define time periods during which UEs in particular UE groups are powered up to access data messages. The network schedules UE group identifiers and associated data message pointers within multiple paging windows listed in the network memory such that each UE accesses only one paging window. The network determines whether more than one paging window is necessary for each particular UE, and whether there are any scheduling conflicts between data messages for a particular UE. If there are no conflicts, the UEs are notified of their assigned paging window(s). Otherwise, data messages are rescheduled as necessary.

Description

technical field [0001] Inventions related to the efficient transmission of information on mobile phone systems. In particular, the invention relates to efficient delivery of multicast and broadcast services for UEs, thereby saving radio resources and extending battery life. Background technique [0002] The third generation (3G) mobile phone system is still being revised to improve the transmission efficiency of multicast and broadcast services for user equipment (UE). In these mobile phone systems and networks, various parameters need to be optimized. Typically, when a single parameter is optimized, the optimization of another parameter is sacrificed. Wherein, the conflicting relative parameters include: user equipment (UE) power consumption and radio resource utilization. [0003] For minimum power consumption, user equipment (UE) should try to avoid actively searching for signals. Such as figure 1 As shown, when the user equipment (UE) is not searching for the paging...
