Claim:
A method in a data collection network node for gathering information to be used for identifying at least one of a plurality of different tracking areas as a primary tracking area in which a particular user equipment is most likely to be located, wherein a wireless communication network comprises the data collection network node, the method comprising: retrieving a tracking area identity; registering information about usage of a tracking area identified by the retrieved tracking area identity; determining a measure for the user equipment being located in the tracking area identified by the retrieved tracking area identity, wherein the measure is based on one or more of the probability of receiving a page response from the user equipment if the user equipment is located in that tracking area, the time spent by the user equipment in the tracking area, and tracking area border crossings by the user equipment; and selecting said tracking area identity as the identity of said at least one primary tracking area, if the measure exceeds a threshold; wherein the data collection network node comprises a network node that manages the mobility of the user equipment; and wherein the retrieved tracking area identity is received from a radio network node in the wireless communication network.
