Embodiment Construction
[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0037] figure 1 It shows the flow chart of the method for 4G network planning and optimization based on the cycle flower arrangement algorithm provided by the embodiment of the present invention, refer to figure 1 , the method includes the following steps:
[0038] Step S101. Determine the preferred base station group for the round robin algorithm.
[0039] Specifically, in this step, it depends on the application of this method. For example, when this method is applied to the PCI planning of a new station or only for the PCI optimization of several base stations, different angles refer to these base stations that need to be planned or optimized. , such as a total of 3 base stations need to optimize the PCI, and the preferred base stati...

The invention relates to the wireless technology field and provided a 4G network program and optimization method based on a cycle flower arrangement algorithm. According to the method, a first-choice base station set of the cycle algorithm is determined, one base station is selected, the network is divided into multiple groups, each group realizes independent operation, and only data of one station is modified, namely flower arrangement; calculation continues, data of all other base stations of the groups are not changed, one scheme is generated for one cycle, subsequent cycle starts from selecting another base station from the first-choice base station set, the base stations of the whole network are divided into multiple groups, the previous process is repeated, so multiple schemes are generated, and thereby the optimal scheme is selected through quantification comparison. The whole process is the cycle flower arrangement algorithm, operation complexity is greatly reduced, the optimal effect is realized through least modification, influence on the network is greatly reduced, and network quality is effectively improved.
Description
technical field [0001] The invention relates to the field of wireless technology, in particular to a method for planning and optimizing a 4G network based on a circular flower arrangement algorithm. Background technique [0002] The PCI (Physics Cell Identifier) of the mobile 4G network (TD-LTE) is the abbreviation of the physical cell identification, also known as the physical cell ID. The TD-LTE network system has a total of 504 physical cell IDs. A number between 503 and 503 is enough. However, there are only three modulus values (that is, the remainder of 504 / 3): 0, 1, and 2. In the past, when planning or optimizing, the modulus value configuration method of the cells in the same station was used in sequence. For example, the first cell uses modulo 0, Modulus 1 is used for the 2nd cell, and modulus 2 is used for the 3rd cell. This planning method is suitable for networks with standardized site layout and consistent cell orientations throughout the network, but for ...
