Abstract
A network device 10 according to the present invention includes a management unit 11 configured to manage a cell-to-be-monitored and a cell-to-be-controlled in association with each other, and an instruction unit 13 configured to give a predetermined instruction to a radio base station which manages the cell-to-be-controlled in association with the cell-to-be-monitored, upon detection of a predetermined trigger in the cell-to-be-monitored.
Claims5
A network device comprising:
- a management unit configured to manage a cell-to-be-monitored and a cell-to-be-controlled in association with each other;
- and
- an instruction unit configured to give a predetermined instruction to a radio base station which manages the cell-to-be-controlled in association with the cell-to-be-monitored, upon detection of a predetermined trigger in the cell-to-be-monitored, wherein the predetermined trigger is detected when the number of mobile stations on standby, or in process of establishing a radio connection in the cell-to-be-monitored, exceeds a predetermined number, and the instruction unit instructs the radio base station to activate the cell-to-be-controlled, and wherein an area covered by the cell-to-be-controlled geographically differs from and does not overlap an area covered by the cell-to-be-monitored.
A radio base station comprising:
- a management unit configured to manage a cell-to-be-monitored and a cell-to-be-controlled in association with each other;
- and
- a controller configured to activate the cell-to-be-controlled which is managed in association with the cell-to-be-monitored, upon detection of a predetermined trigger in the cell-to-be-monitored, wherein the predetermined trigger is detected when the number of mobile stations on standby, or in process of establishing a radio connection in the cell-to-be-monitored, exceeds a first predetermined number, or
- the controller is configured to deactivate the cell-to-be-controlled upon detection of the predetermined trigger, wherein the predetermined trigger is detected in the cell-to-be-monitored, when the number of mobile stations on standby, or in process of establishing a radio connection in the cell-to-be-monitored falls below a second predetermined number, and wherein an area covered by the cell-to-be-controlled geographically differs from and does not overlap an area covered by the cell-to-be-monitored.
