DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of a radio base station controller according to an embodiment of the present invention will be described with reference to FIG. The control distribution unit 1 includes a control request 101 transmitted to each wireless base station.
Is entered. The control distribution unit 1 is connected to a database 2 that stores priority information of each wireless base station. Further, the output of the control distribution unit 1 is input to the priority control processing sequence 31 and the normal control processing sequence 32. The outputs of the priority control processing sequence 31 and the normal control processing sequence 32 Has been entered.

Next, the operation of this embodiment will be described. The control distributing means 1 includes a control request 101 transmitted to each wireless base station.
Is input to the database 2 and the input control processing 1
Inquire about priority information of the wireless base station to which 01 is transmitted. As a result of the inquiry, when the control request 101 is a control request for a wireless base station to be subjected to priority control, the control request is transmitted to the priority control processing sequence 31. In the case of a control request to a non-priority wireless base station, the normal control processing sequence 32
Send a control request to. The priority control processing sequence 31 and the normal control processing sequence 32 hold the input control requests and, when outputting the held control requests, output in the order of input.

The control requests output from the priority control processing sequence 31 and the normal control processing sequence 32 are input to the control processing means 3.
The control request output from the normal control processing sequence 32 is input when the output from the priority control processing sequence 31 is lost. The control processing means 3 processes the input control requests in the order of input.

Next, referring to the flowchart of FIG.
An operation in which the control distribution unit 1 distributes the input control request will be described. S201 and the like in the following text are
Represents the steps in the flowchart. When the control request 101 is input to the control distribution unit 1 (S201), the control distribution unit 1 inquires of the database 2 about the priority information of the wireless base station to which the input control request 101 is transmitted (S202). . As a result of the inquiry, if the control request is a control request for a wireless base station to be subjected to priority control, the control request is transmitted to the priority control processing sequence 31 (S203, S204). As a result of the inquiry, if the control request is a control request for a wireless base station other than the priority control target, the control request is transmitted to the normal control processing sequence 32 (S203, S205).

Next, referring to the flowchart of FIG.
An operation in which the control processing means 3 preferentially inputs and processes the output from the priority control processing sequence 31 will be described. The control processing means 3 inquires of the priority control processing sequence 31 about the presence or absence of a control request (S301). If there is a control request as a result of the inquiry to the priority control processing sequence 31, this control request is executed (S
302, S303), and return to S301. If there is no control request as a result of the inquiry to the priority control processing sequence 31, the control processing means 3 inquires of the normal control processing sequence 32 whether or not there is a control request (S302, S304). If there is a control request as a result of the inquiry to the normal control processing sequence 32, the control request is executed (S305, S306), and the process returns to S301. As a result of the inquiry to the normal control processing sequence 32, if there is no control request, the process returns to S301.

In the above embodiment, two control processing sequences, a priority control processing sequence 31 and a normal control processing sequence 32, are provided. In addition to these control processing sequences, the priority control processing sequence 31 is provided. By providing a control processing sequence having an intermediate priority between the control processing sequence 31 and the normal control processing sequence 32, three or more control processing sequences can be provided. Also, the present invention
As long as it controls a plurality of devices, the present invention can be applied to a device other than the wireless base station in the above embodiment. Further, if the contents of the database 2 holding the priority information are changed depending on the time zone or day, it is possible to cope with the traffic situation that changes depending on the time zone or day.

[0015]

According to the present invention, it is possible to preferentially designate a radio base station to be controlled in accordance with a traffic situation or an environmental condition in system operation, so that a radio base station in a high traffic area can be specified. Control quickly,
The number of users affected by the control delay can be minimized.
