Apparatus and method for managing tracking area list in wireless communication system

A method of operation of a node controlling a network configuration in a wireless communication system, the method comprising:

• generating information for determining a bundle relationship between tracking areas, the bundle relationship representing the relationship of, although there is a request for tracking area update for one tracking area among a plurality of tracking areas, comprising not only the update-requested tracking area but also the remnant tracking areas together in a tracking area list of a mobile station (MS);
• and
• transmitting the information for determining the bundle relationship, to a node managing tracking area lists of MSs.

A mobile station (MS) apparatus in a wireless communication system, the apparatus comprising:

• a modulator/demodulator (MODEM) configured to send a message of transmitting a request for tracking area update for a first tracking area, and receive a tracking area list to which the first tracking area and a second tracking area are added;
• and
• a controller configured to update a stored tracking area list by the tracking area list to which the first tracking area and the second tracking area are added.

A node apparatus for managing the mobility of a mobile station (MS) and a tracking area list thereof in a wireless communication system, the apparatus comprising:

• a storage unit configured to store information of a bundle relationship between tracking areas, the bundle relationship representing the relationship of, although there is a request for tracking area update for one tracking area among a plurality of tracking areas, comprising not only the update-requested tracking area but also the remnant tracking areas together in the tracking area list of the MS;
• and
• a controller configured to determine the bundle relationship and, if there is a request for tracking area update for a first tracking area from the MS, determine whether a second tracking area having the bundle relationship with the first tracking area exists, and add the first tracking area and the second tracking area in the tracking area list of the MS.
