Abstract

To provide a mobile communication system which can distribute area information from a radio Node to a mobile terminal in a unit of cell. A mobile communication system comprising: a radio Node having a plurality of cells; host apparatus connected to the radio Node so as to be able to communicate information with the radio Node; and a mobile terminal receiving information distributed from the radio Node, wherein area information different for each cell is distributed from the radio Node to the mobile terminals 40 existing in the cell included in the radio Node, the area information is transmitted, together with control information including type information added according to a content of the area information, from the host apparatus to the radio Node, and the cell to be distributed with the information is determined based on the type information.

Claims

1. A mobile communication system comprising:

a radio Node having a plurality of cells;

host apparatus connected to the radio Node so as to be able to communicate information with the radio Node; and

a mobile terminal receiving information distributed from the radio Node, wherein

area information different for each cell is distributed from the radio Node to the mobile terminals existing in the cell included in the radio Node,

the area information is transmitted, together with control information including type information added according to a content of the area information, from the host apparatus to the radio Node, and

the cell to which each area information is to be distributed is determined based on the type information.

2. A mobile communication system according to claim 1, wherein the area information is carried in report information and distributed to the mobile terminal.

3. A mobile communication system according to claim 1, wherein the area information is carried in an area information distribution message irrelevant to report information and distributed to the mobile terminal.

4. A mobile communication system according to claim 1, wherein the host apparatus includes a radio Node controller, and a mobile exchange network or a network element manager;

the radio Node controller is connected to a plurality of radio Nodes so as to be able to communicate information with the radio Nodes, and corresponds to the host apparatus for the radio Nodes; and

the mobile exchange network or the network element manager is connected to a plurality of radio Node controllers so as to be able to communicate information with the radio Node controllers, the mobile exchange network or the network element manager corresponding to the host apparatus for the radio Node controllers and being also a distribution source of the area information, and

either one of the radio Node, the radio Node controller, and the mobile exchange network or the network element manager performs determination of the cell to which the area information is to be distributed based on the type information.

5. A mobile communication system according to claim 1, wherein the host apparatus includes a radio Node controller, and a mobile exchange network or a network element manager;

the radio Node controller is connected to a plurality of radio Nodes so as to be able to communicate information with the radio Nodes, and corresponds to the host apparatus for the radio Node; and

the mobile exchange network or the network element manager is connected to a plurality of radio Node controllers so as to be able to communicate information with the radio Node controllers, the mobile exchange network or the network element manager corresponding to the host apparatus for the radio Node controllers and being a distribution source of the area information, and

determination of the cell to which the area information is to be distributed based on the type information is performed by an arbitrary combination of the radio Node, the radio Node controller, and the mobile exchange network or the network element manager,

the apparatus corresponding to the uppermost apparatus in the arbitrary combination determines the cell to which the area information is to be distributed based on the type information, sets up in the control information searched information indicating that the cell has been determined, and transmits the area information together with the control information to the lower apparatus,

the lower apparatus having received the area information checks if the searched information has been set up in the control information, and when the searched information has been set up, the lower apparatus distributes the area information to a lower apparatus including the cell to be distributed with the information or to the cell to be distributed with the information, without performing determination of the cell to be distributed with the information based on the type information, and when the searched information has not been set up, the lower apparatus performs determination of the cell to be distributed with the information based on the type information, sets up in the control information the searched information indicating that the cell has been determined, and distributes the area information to the lower apparatus including the cell to be distributed with the information or to the cell to be distributed with the information.
