IDENTIFICATION OF UNIQUE CELL IDENTITY FOR BUILDING NEIGHBOUR CELL RELATION

摘要

The present invention relates to cellular communications networks and in particular to a method for determining the unique identity of a neighbouring cell as reported by a mobile terminal for the autonomous establishment of neighbour cell C1, C2 relations by the radio base stations (12). For a neighbour cell relation to be established, the unique cell identity of the cell is needed in addition to the physical cell identity as is included in the reports from an active mode terminal. It is cumbersome for an active mode mobile terminal to determine the unique cell identity, and it impacts the traffic service to the mobile terminal. The present invention present a method for finding a mobile terminal capable of determining the unique cell identity with as little impact on its service as possible. Also, the need for selecting a mobile terminal for detecting the unique cell identity is adapted to how urgent it is to establish the cell relation.
