FIG. 3 is a flow chart illustrating exemplary method steps performed in a wireless device. As mentioned above, the proposed method could be considered as a network centric solution as well as a device centric solution, and some features presented as performed in the wireless device will be optional in the network centric solution, while other features disclosed above for the network node will be optional in a device centric solution.

In an optional, preparatory step, information about the location of a second network is proactively gathered, in absolute geographical terms and/or in relation to the network nodes of the first network. This can be done using wireless device/user equipment, UE, measurements from UEs detecting identifiers of a second network. The wireless device may contribute in determining the location of the second network by determining its own location; in step S31 disclosed as determining S31 the location of the wireless device. Optionally, the location of the wireless device is reported to the serving network node by transmitting S31a a report comprising information on the location of the wireless device and/or proximity to the second network.
