Problems solved by technology

[0004] However, the azimuth angle of the antenna may be changed, so the network working parameters or talent collection data are still used to determine the matching inter-frequency band cell when performing cell expansion. The accuracy of the cell is low, and the expansion effect is poor.

Embodiment Construction

[0066] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0067] At present, it is difficult to achieve the same area with the independent antenna feeder coverage method, and the network expansion is based on the original network working parameters (such as the azimuth angle of the antenna, etc.) etc.) as a reference, and then expand the capacity by querying different frequency band cells that match the network working parameters or talent collection data. However, the azimuth angle of the antenna may be changed, so the accuracy of determining the matching inter-frequency band cell by still using the network working parameters or talent collection data during cell expansion is low, and the expansion effect is poor.

[0068] In view of t...

Abstract

The invention discloses a cell capacity expansion method and network equipment, which are used for improving the capacity expansion effect of a cell. The method comprises the following steps: determining the coverage area of a cell to be expanded and at least one covered hotspot area, wherein the service volume of each hotspot area is greater than a first preset threshold; determining at least onedifferent-frequency-band neighbor cell of the cell to be expanded, wherein the frequency band corresponding to the different-frequency-band neighbor cell is different from the frequency band corresponding to the to-be-expanded cell; determining a different-frequency-band target expansion cell of the cell to be expanded from at least one different-frequency-band neighbor cell according to the overlapping coverage degree of at least one hotspot region and each different-frequency-band neighbor cell, wherein the overlapping coverage is used for indicating the proportion of the sampling points inthe to-be-expanded cell.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a cell expansion method and network equipment. Background technique [0002] The wireless communication network includes a plurality of terrestrial base stations, and when the terminal equipment is located in a certain cell of a base station, the terminal equipment can visit the base station. As the number of terminal devices accessing the base station increases, the base station may not be able to carry more terminal devices to communicate at the same time. In this case, the network needs to be expanded. [0003] An existing network expansion method is to increase the frequency of the base station, that is, increase the frequency point of the base station to transmit / receive signals, so that the base station can communicate with more terminal devices at the same time to achieve the purpose of network expansion. At present, an implementation method of increasing t...
