Patent ID: 7949350

Claim:
A mobile communication system comprising: a radio Node having a plurality of cells; a radio Node controller connected to a plurality of radio Nodes so as to be able to communicate information with the radio Nodes; a mobile exchange network or a network element manager connected to a plurality of radio Node controllers so as to be able to communicate information with the radio Node controllers; 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, wherein the area information is transmitted, together with control information including type information added according to a content of the area information, from the mobile exchange network or the network element manager to the radio Node controller, and from the radio Node controller to the radio Node, wherein the cell to which each area information is to be distributed is determined based on the type information, wherein the mobile exchange network or the network element manager being a distribution source of the area information, wherein 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, wherein an apparatus corresponding to an 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 a lower apparatus, and wherein 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.
