Patent ID: 7957743

Claim:
A method in a radio base station, or base station controller, of a wireless telecommunications system for updating a neighbor cell list associated with a first cell served by said radio base station, said list containing elements that identify other cells that have a neighbor cell relationship with the first cell, wherein radio base stations in said system broadcast both a non-unique identity and a unique identity of the cells that they serve, the method comprising the steps of: communicating with a mobile terminal in the first cell; receiving from the mobile terminal a non-unique identification of a second cell detected by said mobile terminal; comparing the non-unique identity of the second cell with elements in the neighbor cell list and, if an identity ambiguity exists, then: instructing the mobile terminal to determine the unique cell identity of the second cell; receiving unique cell identifier information relating to the second cell from the mobile terminal; and, associating the non-unique cell identity of said second cell with the unique cell identity of said second cell in said neighbor cell list.
