Wireless communication method and system for efficiently managing paging windows and data messages


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.
