Embodiment Construction

[0028] The specific implementation manners of a cell merging method and device in a TD-LTE network provided by the embodiments of the present invention will be described below with reference to the drawings in the description.

[0029] A method for merging cells in a TD-LTE network provided by an embodiment of the present invention, such as image 3 As shown, it specifically includes the following steps:

[0030] S301: According to the NES test data of the reverse coverage test system of each cell in the set area, respectively calculate the interference value between each cell and each adjacent cell, and the sum of the interference values ​​between each cell and all adjacent cells;

[0031]S302: According to the order of the sum of the interference values ​​from large to small, sequentially determine whether each cell has been selected as a seed cell and whether it has been used as a cell to be merged as a seed cell, if not, execute step S303; if yes, execute step S304;

Abstract

The embodiment of the invention provides a method and device for cell combination. The method comprises the steps that annoyance values between cells and adjacent cells of the cells and annoyance value sums of the cells and all the adjacent cells of the cells are respectively calculated according to NES test data of the cells. Seed cells are determined according to the large-to-small sequence of the annoyance value sums, cells to-be-combined corresponding to the seed cells are selected according to the annoyance values between the seed cells and the adjacent cells of the seed cells, the seed cells are combined with the cells to-be-combined corresponding to the seed cells, and a first logic cell group is obtained. Obtained first logic cells are exchanged according to group regulations to obtain a plurality of second logic cell groups. After network performance of the first logic cell group and the second logic cell groups is evaluated, and the logic cell with a network performance evaluation value larger than a set threshold is output. The method and device for cell combination can ensure good TD-LTE network performance, save manpower and reduce cost.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a cell combining method and device. Background technique [0002] The Time Division Long Term Evolution (TD-LTE) network adopts Orthogonal Frequency Divided Multiple Access (OFDMA), which divides the system frequency band into sub-channels at 15KHz intervals. The center frequencies of the sub-channels do not overlap with each other. On the one hand, the orthogonality between frequencies is used as a way to distinguish users. On the other hand, it can better resist frequency selective fading. [0003] In the TD-LTE network, user information in each cell is carried on different sub-channels that are orthogonal to each other. This way of carrying makes the interference in each cell have little impact on the performance of the TD-LTE network, but affects the performance of the TD-LTE network. A major factor in performance is the interference between each cell an...
