Apparatus, and an associated method, for performing link layer paging of a mobile station operable in a radio communication system
First Claim
1. In a radio communication system having a network part and at least a first mobile station with which a communication session is effectuable by way of the network part, the network part defined in terms of logical layers including a lower logical layer and at least a higher logical layer positioned thereabove, an improvement of apparatus for facilitating paging of the mobile station, said apparatus comprising:
- a tracking agent embodied at the higher logical layer, said tracking agent for tracking positioning of the mobile station, the positioning of the mobile station tracked in terms of a lower logical layer paging area and for cacheing indications of the positioning of the mobile station, the indications cached by said tracking agent retrievable to perform paging of the mobile station, the paging at least initially performed in areas associated with the positioning of the mobile station.

Abstract
Apparatus, and an associated method, for paging a mobile station operable in a WLAN. Logical layer-2 paging is provided pursuant to a tracking agent protocol. A tracking agent is provided that tracks the location at a logical layer-2 logical level. A paging cache is maintained that identifies logical layer-2 paging areas in which the mobile station is most recently associated. When a communication session is initiated, a page is broadcast throughout the layer-2 logical layer paging area in which the mobile station is indicated to be positioned.

15. In a method of communicating in a radio communication system having a network part and at least a first mobile station with which a communication session is effectuable by way of the network part, the network part defined in terms of logical layers including a lower logical layer and at least a higher logical layer positioned thereabove, an improvement of a method for facilitating paging of the mobile station, said method comprising:
-
tracking, from the higher logical layer, lower-logical-layer positioning of the mobile station;
cacheing indications of the positioning of the mobile station tracked during said operation of tracking; and
selectably paging the mobile station at least initially in areas associated with the lower-logical-layer positioning of the mobile station, indications of which are cached during said operation of cacheing. - View Dependent Claims (16, 17, 18, 19, 20)
