SCRAMBLING CODE SELECTION METHOD Russian patent published in 2015 - IPC H04W24/02 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to communication systems. A base station receives from a management node a first list of identifying codes and a second list of identifying codes, wherein the identifying codes of the first list can appear in neighbour cell lists of base stations outside said group, and the identifying codes of the second list can not appear in neighbour cell lists of base stations outside said group. The base station determines whether there is at least one identifying code either in the first list of identifying codes or the second list of identifying codes that is not used by any other base station in said group. If there is at least one identifying code in the first list of identifying codes and at least one identifying code in the second list of identifying codes that are not used by any other base station in said group, an identifying code from the first list of identifying codes is selected in preference to an identifying code from the second list of identifying codes.

EFFECT: improved location area update; the base station forms part of a group of base stations within a cellular communication network and selects an identifying code for use in identifying data transmissions from the base station.
