Abstract
A user equipment (UE) in a communication system can keep track of the cell/frequency deployment of a network operator preferred by the user, and based on the tracked information, the UE can build up its own user-specific Neighbor Cell List. When the UE is roaming, the UE does received-signal measurements according to cells and carrier frequencies identified in the broadcast Neighbor Cell Lists of the roamed-into network, but the UE also does received-signal measurements (with higher priority) according to the user-specific Neighbor Cell List that it has built up. Accordingly, a UE implementing a user-specific Neighbor Cell List analyzes its radio environment based on received signals and stores information about that environment, including user-preference information that prioritizes cells in the radio environment. The UE can then carry out cell search based on the stored environment and user-preference information.
