Device and method for determining expansion frequency points of cell

Abstract

The invention relates to the field of mobile telecommunication, in particular to the technology for expanding frequency of a base station of a cell. The invention provides a device and a method for determining expansion frequency points of the cell. The method comprises the following steps of: determining a neighboring cell of the cell to be expanded; determining signal intensity of all the frequency points of the neighboring cell on the junction of the neighboring cell and the cell to be expanded; and determining the expansion frequency points of the cell to be expanded according to the determined signal intensity. Compared with the signal intensity of the central point of the cell, the signal intensity of the neighboring cell on the cell junction more completely reflects the strength of the interference of all the frequency points of the neighboring cell with the cell to be expanded, so that the expansion frequency points of the cell to be expanded can be selected according to the signal intensity to make the interference strength as small as possible. The method for determining the expansion frequency points does not depend on changing-over relation definition and changing-over statistics of the conventional networks to select the expansion frequency points, has simple calculation process, can quickly select expansion frequency and improves frequency expansion efficiency.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to the technology of frequency expansion for base stations of cells. Background technique [0002] The GSM cellular radio network comprises a plurality of terrestrial base stations to which a mobile terminal has access when the mobile terminal is located in the cell of the base station. With the rapid increase in the number of mobile terminals, the base stations in the existing network may not be able to carry and handle too many communication services; therefore, the network needs to be transformed to achieve network expansion. [0003] Currently, two methods are usually used for network expansion. One is the method of adding base stations: by adding base stations, the number of terminals that can be accommodated in the network can be increased, thereby achieving the purpose of network expansion. However, using this method of capacity expansion, the construction cost will be h...

Problems solved by technology

Therefore, for a cell without a clear handover relationship, or a cell with an incomplete handover definition, or a newly opened cell, this method cannot be used to select a frequency point for capacity expansion for cell frequency expansion, and can only be manually selected. It is time-consuming and labor-intensive to perform frequency expansion at a certain point, which also leads to low expansion efficiency.
