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.

Claims

1. A WLAN, comprising:

a means for establishing paging areas;

a means for communicating access group information to a computing device; and

a means for locating a computing device within the WLAN.

2. A method for implementing dormant mode with paging in a WLAN, comprising:

establishing paging areas;

communicating access group information to a computing device; and

locating a computing device.
