Abstract:
1. A method comprising: detecting at a control node a transition of a user equipment (UE) from a first cell to a second cell to obtain at least a second cell identifier; determining at the control node whether the detected UE transition constitutes a transition from a first charging area to a second charging area using the second cell identifier by comparing the second cell identifier to a charging area configuration, wherein a charging area includes a plurality of cells that are each served by at least one base station and wherein the plurality of cells are defined based at least in part on some commonality in location-based services, and independent of a tracking area or routing area; and if it is determined at the control node that the detected UE transition constitutes a transition from the first charging area to the second charging area, providing from the control node a report of the determined UE transition from the first charging area to the second charging area to a policy server for a propagation of an updated location information of the UE including the determined UE transition; wherein the comparing the second cell identifier to the charging area configuration includes comparing the second cell identifier to a first set of cells included in the charging area configuration that form the first charging area to determine whether the second cell is a part of the first set of cells.
