Embodiment Construction

[0058] Fig. 1 is a diagram showing the structure of a wireless cellular telecommunication network in which the present invention is implemented.

[0059] In the wireless cellular telecommunication network of Figure 1, two mobility management entity shares, labeled 40a and 40b, are shown.

[0060] The mobility management entity share 40a includes, for example, two mobility management entities 20a and 20b, and the mobility management entity share 40b, for example, includes two mobility management entities 20c and 20d.

[0061] Both the mobility management entities 20a and 20b are connected to manage the cell 15 through the telecommunications network 50a a1 to 15 a10 and 15 ab1 to 15 ab14 Each base station BTS of one of the cells, where cell 15 a1 to 15 a10 and 15 ab1 to 15 ab14 Included in the tracking area 70a managed by the mobility management entities 20a and 20b.

[0062] Mobility management entities 20c and 20d are connected to manage cell 15 through telecommunicati...

Abstract

The present invention concerns a method for determining a tracking area of a wireless cellular telecommunication network comprising plural tracking areas, each tracking area comprising plural cells in which mobile terminals are located, at least two tracking areas comprising cells comprised in the at least two tracking areas and cells belonging to a single tracking area, each cell being managed by a base station of the wireless cellular telecommunication network. One base station managing a cell comprised in the at least two tracking areas executes the steps of: - transferring a message to at least a mobile terminal comprised in the cell managed by the base station, the message comprising the identifiers of the at least two tracking areas in which the cell managed by the base station belongs to, - receiving a message from the mobile terminal, the message comprising one single identifier among the identifiers transferred to the mobile terminal, the identifier being the identifier of the tracking area selected by the mobile terminal.

Description

technical field [0001] The present invention relates to a method and a device for determining a tracking area of ​​a wireless cellular telecommunication network comprising a plurality of tracking areas. Background technique [0002] A wireless cellular telecommunication network such as a mobile telecommunication network that provides telecommunication services to mobile terminals roaming within a certain area (wherein the area is composed of multiple cells of a base station of the wireless telecommunication network), often provides mobile telecommunication operators with means for determining the location of a mobile terminal at any time in order to initiate the establishment of a communication session with the mobile terminal. [0003] Typical wireless cellular telecommunication networks are able to track the location of a mobile terminal in idle mode using a Tracking Area (TA). Each cell is assigned to a Tracking Area. When a mobile terminal in idle mode enters a cell in...
