Claim Text:
1. A method of managing signaling in a radio access network (RAN), wherein the RAN includes a plurality of base stations each providing a respective coverage area in which to serve wireless communication devices (WCDs), and wherein the RAN includes a paging controller, the method comprising: determining, in the paging controller, that a particular WCD should be paged; responsive to the determination that the WCD should be paged, the paging controller determining a last known coverage area for the WCD, the last known coverage area being provided by a base station in the RAN with which the WCD was communicating when the WCD last transitioned to an idle mode; responsive to the determination that the WCD should be paged, the paging controller determining an idle duration for the WCD, the idle duration being an amount of time that has passed since the WCD last transitioned to the idle state in the last known coverage area; determining, by the paging controller, one or more target coverage areas based on the determined last known coverage area, the determined idle duration, and data regarding past activities of the WCD; and transmitting a page request, from the paging controller to one or more base stations providing the one or more determined target coverage areas, to cause the one or more base stations to page the WCD.
