The exemplary embodiments of the presently claimed invention relate to a method and a radio base station (600) for identifying candidate or neighbor base stations. The radio base station (600) is configured to include in a first message an information element (IE) including the name of the radio base station (600) and to transmit this message, via the X2 interface, to a candidate or target radio base station. In response, the target base station includes its name in an IE of a response message and send it to the first (initiating) radio base station (600). The name sharing improves visualization and topology since the closest neighbor radio base station is easily identifiable when building radio base station's relations.
