Method and system for managing signaling in a wireless communication network
First Claim
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.

Abstract
Disclosed is a method and system for managing signaling in a communication network. A paging controller determines one or more target coverage areas to attempt a paging request for a wireless communication device (WCD) based on (i) a coverage area last serving the WCD (“last known coverage area”) and (ii) an amount of time passed since the WCD last transitioned from a connected state to an idle state in the last known coverage area (“the idle duration”). The paging controller can utilize a database that specifies, on a per WCD basis, one or more records of associated data items for different last known coverage areas, idle durations, and target coverage areas. With knowledge of a last known coverage area and idle duration for a WCD, database record(s) can be identified and target coverage area(s) can be determined. A paging request can then be transmitted to the determined target coverage area(s).

12. A paging controller, comprising:
-
a processing unit; a data storage; and program instructions stored in the data storage and executable by the processing unit to; (i) determine that a particular wireless communication device (WCD) in a radio access network (RAN) should be paged, (ii) determine 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, (iii) determine 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, (iv) determine 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 (v) transmit a page request 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. - View Dependent Claims (13, 14, 15, 16, 17, 18)

20. A method comprising:
-
receiving, in a paging controller, a first communication identifying a particular wireless communication device (WCD) in a radio access network (RAN) and including an indication of a first time at which the WCD transitioned from a connected mode to an idle mode and an indication of a first coverage area in which the WCD made the transition at the first time; after receiving the first communication, receiving, in the paging controller, a second communication identifying the WCD and including an indication of a second time at which the WCD transitioned from the idle mode to the connected mode and indication of a second coverage area in which the WCD made the transition at the second time; determining, by the paging controller, an idle duration based on the difference between the second time and the first time; storing, in a database, a record including an indication of the first coverage area, an indication of the idle duration, and an indication of the second coverage area, the record being associated with the WCD; determining, in the paging controller, that the WCD should be paged; accessing the record in the database to make a determination, by the paging controller, where to page the WCD; and paging the WCD in accordance with the determination where to page the WCD.
