Abstract

An operation control method in a base station of a wireless communication system includes: checking whether or not an allowed mobile station exists in coverage of the base station and overall coverage of base stations adjacent to the base station; and controlling the base station to perform transmission/reception at a predetermined period through a first discontinuous operation, when the allowed mobile station does not exist in the coverage of the base station and the overall coverage of the adjacent base stations.

Claims

1. An operation method of a first base station, comprising:

checking whether or not an allowed mobile station exists in coverage of the first base station and coverage of a second base station adjacent to the first base station; and

discontinuously operating with a first period, if the allowed mobile station does not exist in the coverage of the first base station and the coverage of the second base station.

2. The operation method of claim 1, further comprising changing the first base station into an active state, if entry of the allowed mobile station to the coverage of the first base station is checked or camping information of the allowed mobile station is received from the second base station.

3. The operation method of claim 2, wherein the entry of the allowed mobile station to the coverage of the first base station is checked by using handover request information transmitted to the second base station from the allowed mobile station.

4. The operation method of claim 1, further comprising:

discontinuously operating with a second period having lager on/off rate than on/off rate of the first period, if the allowed mobile station in a deactivated state enters to the coverage of the second base station.

5. The operation method of claim 1, wherein a tracking area identity of the first base station is same as a tracking area identity of the second base station.

6. A base station comprising:

a data processing unit configured to transmit/receive data or signals to and from a mobile station;

a network processing unit configured to process data into a network; and

a control unit configured to discontinuously operate the data processing unit with a predetermined period, if an allowed mobile station does not exist in coverage of the base station and coverage of an adjacent base station adjacent to the base station.

7. The base station of claim 6, wherein the control unit changes the data processing unit into an activate state, if camping information of the allowed mobile station is received from the adjacent base station through the network processing unit.
