Abstract

The invention discloses a network capacity expansion method and device, and relates to the technical field of communications. The problem that the availability of realizing the network capacity expansion through a sector splitting technology is low caused by less accessible terminal number and high lost connection rate in an overlapping area of splitting sectors in an LED network can be solved. The method disclosed by the invention comprises the following steps: determining a normal direction of an original sector as an initial normal direction of the existing sector, wherein the existing sector comprises a first sector and a second sector; determining a candidate normal direction of the existing sector according to the initial normal direction, an adjusting range and an adjusting step length if an average terminal number in each unit area in the overlapping area on the initial normal direction is greater than or equal to the average terminal number in each unit area in a base station coverage area; and determining the normal direction of the existing sector according to the minimum value of the terminal number in the overlapping area on each candidate normal direction. The method and device disclosed by the invention are suitable for the process of expanding the network capacity.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for network expansion. Background technique [0002] After the large-scale deployment of LTE (English: Long Term Evolution, Chinese: Long Term Evolution) network, users' demand for network resources is increasing, the network load is gradually increasing, and network expansion has become an inevitable trend. The methods of network expansion mainly include: increasing the number of base stations, deploying different frequencies and deploying the same frequency. However, the limited area available for deploying base stations makes it impossible to build new base stations in some areas. In addition, the existing frequency band resources are limited, and the frequency band bandwidth of the LTE network is relatively large. As a result, it is impossible to expand the capacity of the site through co-site and different frequency deployment in the LTE network. ...
