Abstract

The invention discloses a method, device and system for obtaining inter-cell handover parameters, which are used to solve the problem in the prior art that the overall network capacity of a block of cells cannot be optimized in a short time by manual means. In the method, the wireless measurement report of the received signal strength reported by the user terminal of each cell in the block of cells is obtained; the difference between the received signal strength of the serving cell and the received signal strength of each neighboring cell in the measurement report is determined; Further obtain the function of the traffic volume from the serving cell to the adjacent cell as the inter-cell handover parameter changes; determine the inter-cell handover parameter that makes the total traffic volume of each cell access in the block of cells the largest through the objective optimization algorithm; according to the The determined inter-cell handover parameters set the inter-cell handover parameters of the block of cells.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method, device and system for acquiring handover parameters between cells. Background technique [0002] Adjusting parameters such as antenna downtilt and handover threshold is a common method for cell capacity optimization. However, the current method of artificially optimizing network capacity usually adjusts the parameters of a limited number of cells (for example: 2-3), which cannot guarantee the optimal network capacity of the entire block of cells. Among them, the block of cells is geographically Adjacent multiple cells or multiple cells that are not adjacent geographically but are configured as adjacent cells. If the capacity optimization of a large area involves factors such as the capacity and resources of the area, it will be difficult to achieve the optimization effect by manually adjusting the parameters, and even if there is improvement, it is mostly ...
