Technique for Updating Cellular Neighbor Relations

Abstract:

A technique for updating a list of neighbor relations between cells (100, 312, 502, 504, 512, 514) of a radio access network, RAN, (304) is described. The cells (100, 312, 502, 504, 512, 514) of the RAN (304) comprise first cells (100, 502, 504) configured to provide radio access according to a first radio access technology, RAT, and second cells (512, 514) configured to provide radio access according to a second RAT that is different from the first RAT. As to a method aspect of the technique, each of at least two of the second cells (512, 514) of the RAN (304) is initiated to transmit a measurement signal to a radio device (310; 1391; 1392; 1430) that is served by one or more cells (100; 312) of the RAN (304) other than the at least two second cells (512, 514) of the RAN (304). A confirmation report indicative of a reception of the measurement signal at the radio device (310; 1391; 1392; 1430) is received from one second cell (512) among the at least two second cells (512, 514). The list of neighbor relations is updated according to the received confirmation report.
