1. A method of paging a mobile station comprising:
- exchanging mobile station information between a plurality of distributed mobility agents, the exchange being initiated by a mobility agent of a last known network access point that has communicated with the mobile station;
paging the mobile station from at least one network access point associated with a second mobility agent of the plurality of distributed mobility agents using an available air interface technology to interface with the mobile station and using the mobile station information;
receiving a page response from the mobile station at a second network access point associated with the second mobility agent;
upon receiving the page response from the mobile station, exchanging information between the second mobility agent associated with the second network access point and the mobility agent of the last known access point; and
sending incoming data to the mobile station via the mobility agent of the last known network access point; and
determining an identity of the mobility agent of the last known network access point that has communicated with the mobile station by the second mobility agent by sending a multicast query from the second mobility agent to a plurality of network access points.

Abstract
Mobile station information is exchanged between a plurality of distributed mobility agents (106, 108). The exchange is initiated by a mobility agent (106) associated with a last known network access point (110) that has communicated with the mobile station (114). The mobile station (114) is paged from at least one network access point using an available air interface technology to interface with the mobile station (114) and using the mobile station information. No centralized controller is used in the paging.

3. A mobility agent of a last known network access point that has communicated with a mobile station comprising:
-
a receiver having an input; a transmitter having an output; and a controller coupled to the receiver and the transmitter, the controller programmed to; exchange mobile station information with at least a second mobility agent at the receiver and transmitter, the exchange being initiated by the mobility agent of the last known network access point that has communicated with the mobile station, the controller further programmed to form and send control messages at the output of the transmitter to initiate paging of the mobile station, receive a page response from the mobile station at a second network access point associated with the second mobility agent; upon receiving the page response from the mobile station, exchange information between the second mobility agent associated with the second network access point and the mobility agent of the last known access point; and send incoming data to the mobile station via the mobility agent of the last known network access point; and wherein an identity of the mobility agent of the last known network access point that has communicated with the mobile station is determined by the second mobility agent by sending a multicast query from the second mobility agent to a plurality of network access points. - View Dependent Claims (4, 5, 6)
