Problems solved by technology

[0005] When only the macro base station is needed to serve UEs in its coverage area, it is not necessary to turn on the micro base station at this time, but if the UEs in the coverage area are distributed around a certain micro base station, and the number of UEs in the coverage area is such that The micro base station satisfies the opening condition, and at this time, it is not necessary to open the micro base station; or, when the traffic volume of the macro base station increases and exceeds the processing capacity of the macro base station, it is necessary to open multiple micro base stations at this time to shunt traffic for the macro base station. However, if the distribution of UEs in the coverage area causes multiple micro base stations to meet the shutdown conditions and shut down, at this time, the shutdown of the micro base station is unnecessary, and the macro base station exceeds the processing capacity without being offloaded by the micro base station
[0006] To sum up, it can be seen that the above-mentioned method of turning on or off the micro base station causes a large processing load of the macro base station, low accuracy of turning on and off the micro base station, and low precision of the micro base station's shunting of the macro base station

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for adjusting the state of a micro base station. Background technique [0002] With the rapid development of smart terminals and mobile Internet technologies, users have higher and higher requirements for wireless data traffic. The existing spectrum and sites can no longer meet the needs of users. Therefore, operators deploy a large number of low-power The edge-shaped cellular access point (micro base station) forms a low-power node layer and reuses the existing spectrum resources of the system in large quantities. [0003] In practical applications, in order to not only meet user needs, but also save energy consumption of micro base stations and reduce co-channel interference to macro base stations, it can be selectively enabled according to the relationship between the traffic volume under macro base stations and the processing capacity of mac...
