Abstract: A method in a base station (110) for enabling the base station (110) to identify a neighboring base station (120) is provided. A request is being sent (303) to a user equipment (130), commanding it to send an identification requesting message to the neighboring base station (120). In response to reception of the sent identification requesting message, a neighboring base station identifier that is associated with and identifies the neighboring base station (120), is received (303).

This can be done at some later point in time, for example in order to request the neighboring base station to perform handover measurements with regard to the same or another user equipment.

Abstract: Identification of network nodes (110a-c) of a first Radio Access Technology, “RAT”, and of a wireless communication network (100), which network nodes (110a-c) are at least potentially neighboring each other. Multiple information sets associated with multiple communication devices (120a-c), respectively, are obtained (204a-b; 401). Each communication device (120a-c) supports both the first RAT and another, second RAT. Each information set, thus associated with a communication device (120a), identifies a network node (110a) of the first RAT, and one or more network nodes (111a) of the second RAT that have been identified by the communication device (120a) when the communication device (120a) was associated with a communicative connection to said identified network node (110a) of the first RAT. The network nodes (110a-b) of the first RAT that are at least potentially neighboring each other are then identified (205; 402) based on the obtained multiple information sets.
