Apparatus, and an associated method, for paging a mobile station operable in a radio communication system
First Claim
1. In a communication system having a network part and a mobile station selectably operable to communicate with the network part by way of a radio air interface, wherein the network part comprises a first access point defining a first coverage area and at least a second access point defining at least a second coverage area, the mobile station operable in an active state and at least a dormant state, an improvement of apparatus for facilitating initiation of a communication session with the mobile station, the mobile station forming a terminating node, said apparatus comprising:
- a location index for indexing together positional indicia associated with the mobile station forming the terminating node, wherein the positional indicia indexed at said location index identifies in which of the first and at least second coverage areas, respectively, that the mobile station forming the terminating node is positioned; and
a page message generator embodied at the network part, said page message generator for generating a page message for broadcast upon the radio air interface throughout an area responsive to the positional indicia indexed at said location index to alert the mobile station of an invitation to initiate the communication session with the mobile station, the page message forming a wake-up indicator, the wake-up indicator detectable by the mobile station when in the dormant state; and
wherein the communication system comprises a WLAN (Wireless Local Area Network) operable pursuant to operating parameters of an IEEE 802.11 operating specification that defines ADD-modify messages, and wherein the information provided to said location index is contained in an ADD-modify messase communicated by the mobile station.

Abstract
Apparatus, and an associated method, by which to page a mobile station to alert the mobile station of a call placed thereto. A location server is provided at which a location index is created and maintained, identifying the location at which the mobile station to which the call is to be terminated is positioned. Page messages are broadcast throughout an area in which the mobile station is indicated to be positioned. The page messages are broadcast in manners that permit the mobile station to detect their transmission even when the mobile station is in a dormant, or other nonactive, state.

12. In a method of communicating in a communication system having a network part and a mobile station selectably operable to communicate with the network part by way of a radio air interface, the communication system comprises a WLAN (Wireless Local Area Network) operable pursuant to operating parameters of an IEEE 802.11 operating specification that defines ADD-modify messages, the mobile station operable in an active state and at least a dormant state, an improvement of a method for facilitating initiation of a communication session with the mobile station, the mobile station forming a terminating node, said method comprising:
-
indexing together positional indicia associated with the mobile station forming the terminating node, wherein the information provided to said location index is contained in an ADD-modify message communicated by the mobile station; and detecting a request for initiation of the communication session; and
responsive thereto generating a page message for broadcast in an area associated with the positional indicia indexed upon the radio air interface to alert the mobile station of an invitation to initiate the communication session with the mobile station, the page message forming a wake-up indicator, the wake-up indicator detectable by the mobile station when in any of the active state and the at least the dormant state. - View Dependent Claims (13, 14, 15, 16)

17. A system for facilitating initiation of a communication session with a mobile station associated with a WLAN (Wireless Local Area Network) which is operable pursuant to operating parameters of an IEEE 802.11 operating specification that defines ADD-modify messages, the mobile station operable in an active state and at least a dormant state, said system:
-
a location index for indexing together positional indicia associated with the mobile station, wherein information provided to said location index is contained in an ADD-modify message communicated by the mobile station; and a page message generator generating a page message for broadcast upon a radio air interface throughout an area responsive to the positional indicia indexed at said location index to alert the mobile station of an invitation to initiate a communication session with the mobile station, the page message forming a wake-up indicator, the wake-up indicator detectable by the mobile station when in the dormant state.
