A METHOD FOR ASSOCIATING A TRACKING AREA IDENTITY LIST WITH A USER EQUIPMENT IN A WIRELESS COMMUNICATIONS NETWORK

摘要

The invention relates to a method for use in a core network node, such as a mobility management entity, in a wireless communication network for associating a tracking area identity list comprising at least one tracking area identity (TAI) with a user equipment. The method comprises the steps of: associating a first tracking area identity list with a user equipment as the user equipment registers with the core network node; sending the first tracking area identity list to the user equipment; and receiving at least one tracking area identity comprising the tracking area identity of a tracking area being used by the user equipment. The method further comprising the steps of: compiling an second tracking area identity list based on the tracking area identity list currently associated with the user equipment and on the received at least one tracking area identity;in case the second tracking area identity list contains a different set of tracking area identities than the tracking area identity list currently associated with the user equipment, sending the second tracking area identity list to the user equipment to replace an earlier tracking area identity list in the user equipment; and associating the second tracking area identity list with the user equipment in place of the tracking area identity list currently associated with the user equipment. The invention further relates to a core network node, such as a mobility management entity, and a computer program product for use in such a core network node.
