Abstract
A method in a network node for enabling proximity detection is presented. The network node is comprised in a wireless communications network and serves a wireless device. According to the method, the network node obtains a fingerprint of a CSG cell, or of an inter-frequency cell. The network node then transmits the fingerprint to the wireless device, thereby enabling the wireless device to determine when it is in the proximity of the cell.
