Embodiment Construction

[0028] According to the antenna angle of each target cell, the embodiment of the present invention determines the candidate neighbors of the planning cell from all target cells; the coverage sub-area of ​​the planning cell to which each candidate neighbor belongs; the candidate neighbors According to the number of base stations between the district and the planning cell, update the candidate neighboring cells of the planning cell; determine the neighboring cells of the planning cell from the updated candidate neighboring cells of the planning cell. With the support of accurate electronic maps and propagation models, neighborhood planning can be carried out, thereby reducing the cost of neighborhood planning and improving the planning speed.

[0029] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] Such as figure 1 As shown, the method for determining neighboring cells in the embodiment o...

Abstract

The embodiment of the invention relates to the technical field of wireless communication, in particular to a method and equipment for determining adjacent cells. The method and equipment for determining the adjacent cells solve the problems in the prior art that planning of the adjacent cells is high in cost, and the planning speed is slow. The method for determining the adjacent cells comprises the steps that for a planning cell, candidate adjacent cells of the panning cell are determined from all the target cells according to the antenna angle of each target cell; a coverage subregion, belonging to each candidate adjacent cell, of the planning cell is determined; according to the number of base stations between the candidate adjacent cells and the planning cell in the coverage subregions, updating processing is carried out on the candidate adjacent cells of the planning cell; the adjacent cells of the planning cell are determined from the updated candidate adjacent cells of the planning cell. By means of the technical scheme of the method and equipment for determining the adjacent cells, the cost of planning of the adjacent cells can be lowered, and planning speed is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and equipment for determining neighboring cells. Background technique [0002] In a wireless communication system, neighbor cell planning is an important part of wireless network planning. The rationality of the neighbor cell list results has a direct impact on the system's operating indicators, the difficulty of network neighbor cell optimization, and user experience. [0003] At present, neighborhood planning is generally carried out on the basis of electronic maps and propagation predictions. [0004] Specifically, the signal strength received by each grid point within the planned area of ​​the electronic map is calculated, and the neighbor list is planned according to the signal strength of the planned area. The accuracy of the neighborhood planning of this technical solution depends on the accuracy of the electronic map and the propagation mo...
