1. A method of establishing paging cycles in a wireless communications system, comprising:
- receiving a paging cycle request from each of the plurality of mobile stations via one or more base stations;
in response to the paging cycle requests, transmitting commands from the one or more base stations to each of the plurality of mobile stations to;
assign a first portion of a plurality of mobile stations to a first paging group, wherein mobile stations in the first paging group can be paged in paging cycles at a first time interval between paging cycles;
assign a second portion of the plurality of mobile stations to a second paging group, wherein mobile stations in the second paging group can be paged in paging cycles at a second time interval between paging cycles, the second time interval being twice the first time interval; and
assign each of the mobile stations in the second paging group to a first subgroup or a second subgroup, wherein mobile stations in the first subgroup and mobile stations in the second subgroup can be paged in alternating respective ones of the paging cycles together with all of the mobile stations in the first paging group, such that mobile stations in the first subgroup are not paged in the same paging cycle as mobile stations in the second subgroup.

Abstract
A system to control paging cycles in a wireless network assigns mobile stations to one of a plurality of paging groups based on the paging cycle requirements of the individual mobile stations. In addition, the mobile stations in a particular paging group are further subdivided into subgroups that may be substantially equal in size. At any particular paging cycle, only one subgroup of a particular paging group is included in the paging process thus reducing the overall number of mobile stations that need to be paged in any particular paging cycle.

14. A method comprising:
-
assigning a paging cycle time to each of a plurality of mobile stations; assigning each of a plurality of mobile stations to one of a plurality of paging groups based on the paging cycle time assigned to each of the plurality of mobile stations; assigning each of the plurality of mobile stations within a first of the plurality of paging groups to a selected one of a plurality of subgroups, wherein each of the plurality of mobile stations in the first paging group can be paged at time intervals associated with the first paging group, but wherein each of the plurality of mobile stations in different ones of the plurality of subgroups are paged in different paging cycles. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A system for controlling paging cycles in a wireless communication network having a plurality of wireless communication devices, the system comprising:
-
a plurality of base stations configured to communicate with the plurality of wireless communication devices; a paging cycle controller associated with at least one of the plurality of base stations, the paging cycle controller being configured to assign a paging cycle time to each of the plurality of mobile stations and to assign each of a plurality of mobile stations to a paging group based on the assigned paging cycle time, the paging cycle controller further configured to assign each of the plurality of mobile stations within a selected one of the plurality of paging groups to a selected one of a plurality of subgroups, wherein each of the plurality of mobile stations in the selected paging group are paged at time intervals associated with the selected paging group, but wherein each of the plurality of mobile stations in different ones of the plurality of subgroups are paged in different paging cycles. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
