Method and apparatus for dormant mode support with paging
First Claim
1. A method for channel allocation for a WLAN, wherein the WLAN comprises a plurality of access point groups with at least one access point group having a plurality of access points, comprising assigning a common dedicated channel for paging for each of the plurality of access point groups to enable paging of a computing device, which is capable of entering and exiting a dormant mode, so that the computing device is able to associate with an access point that is different than the previous access point associated with the computing device only when the computing device crosses a boundary between paging areas of two access point groups.

Abstract
Apparatuses and methods are disclosed herein for implementing dormant mode with paging in a WLAN. Power savings in the computing device and reduction in traffic across the network are achieved by requiring a computing device to inform the WLAN of its location only when it crosses a paging area boundary or is to receive IP traffic. Dormant mode with paging is implemented in a protocol that supports dormant functionality and paging functionality but does not itself provide methods or standards for implementing such functionality, such as the IEEE 802.11. The methods and apparatuses disclosed herein provide the methods needed to implement dormant mode with paging in such a protocol. Generally, the methods and apparatuses for implementing dormant mode with paging basically include (1) establishing paging areas; (2) communicating access group information to a computing device; and (3) locating a computing device.
