4G network program and optimization method based on cycle flower arrangement algorithm

Abstract

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 (PhysicsCellIdentifier) ​​of the mobile 4G network (TD-LTE) is the abbreviation of the physical cell identifier, also known as the physical cell ID. The TD-LTE network system has a total of 504 physical cell IDs. A number in between will do. 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 networks with irr...
