Abstract

The invention discloses a method and device of expanding network capacity, and relates to the technical field of communication. The method and the device can solve the problem that due to poor network performance of an overlay area between two split sectors in an LTE network, the availability of using a sector splitting technology for realizing network capacity expansion in the LTE network is low. The method comprises the following steps: determining the normal direction of an original sector as the initial normal direction of an existing sector, wherein the existing sector comprises a first sector and a second sector which are obtained after the original sector is split in the horizontal direction; determining whether service information of the overlay area between the first sector and the second sector meets specified conditions or not; when the service information of the overlay area meets the specified conditions, determining the adjustment angle of the normal direction of the existing sector according to the service information of a designated area in the overlay area of the existing sector, and adjusting the normal direction of the existing sector. The method and the device are applicable to the process of expanding 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. Network expansion methods mainly include: increasing the number of base stations, co-site deployment with different frequencies, and co-site deployment with 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...
