A base station frequency point selection method, device and base station

Abstract

The invention discloses a base station frequency point selection method, an apparatus and a base station. By using the method, the apparatus and the base station, a base station frequency point is dynamically selected and service performance of a communication network is increased. The base station frequency point selection method comprises the following steps of monitoring whether a preset frequency point selection period reaches or receives a base station closing message sent by another base station; when a condition that the preset frequency point selection period reaches or receives the base station closing message sent by another base station is monitored, according to a quantity of cells which are supported to be simultaneously established and service priority information of current bearing services, determining whether a current moment satisfies a frequency point replacing condition; if the current moment satisfies the frequency point replacing condition, carrying out frequency point scanning and selecting the frequency point according to a scanning result.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a base station frequency point selection method, device and base station. Background technique [0002] Nanocell is a product form that integrates Small Cell (such as Picocell, Femtocell, etc.) , High-capacity broadband access. Although the deployment of the Nanocell network is flexible, its maintenance cost is too high. In order to effectively reduce the operation and maintenance cost and improve the operation and maintenance efficiency, SON (Self-Organizing Network, self-organizing network) is proposed to meet the self-organization and self-management requirements of the Nanocell network. An important aspect in SON technology is frequency point configuration. [0003] At present, the frequency point configuration method adopted in the SON technology is mainly to preempt frequency point resources between Nanocells, and each selects the frequency point wi...

Problems solved by technology

[0004] Usually, the Nanocell network environment is constantly changing. For example, the home-level base station may be closed at any time, and new frequency points will be free; or the addition of new base stations and the selection of frequency points will lead to changes in the interference of each frequency point.

[0005] However, since the frequency point configuration method adopted in SON technology does not consider the above factors, once the frequency point is selected, it will not change in the process of providing communication services, which may lead to the following situation: For example, for a Nanocell, its The preemption method selects the frequency point with the lowest current interference to establish a cell. However, as time goes by, the addition of new base stations may cause interference to the currently selected frequency point, which will cause the signal quality of the Nanocell to decline, thereby affecting The service performance of the Nanocell network is affected; or the base station exits, making the currently selected frequency point not optimal, which will also affect the service performance of the Nanocell network
