Abstract

A method for maintaining a tracking area list, TAL, associated with a first wireless device, WD, in a network having network nodes organized into tracking areas, TA, and arranged to page the first WD. The method includes obtaining data associated with a transition pattern of WDs between TAs in the network, the data being indicative of transition probabilities for WDs moving between the TAs, receiving a message indicating that the first WD is leaving a TA and is entering a current TA, and maintaining the TAL by adding the current TA to the TAL and selecting TAs neighboring the current TA for addition to the TAL based on the transition probabilities of a wireless device moving from the current TA and into neighboring TAs, a neighboring TA associated with high transition probability is selected for addition to the TAL before a neighboring TA associated with low transition probability.
