Description

technical field [0001] The invention relates to the communication field, in particular to a PCI planning method for an LTE network. Background technique [0002] In the construction and optimization maintenance of LTE network, interference is one of the key factors affecting network quality. It is an important part of whether it can be fully utilized, and it is also one of the important tasks of network planning and optimization. Since the low-frequency band is occupied by 2 / 3G, domestic LTE (LongTerm Evolution) currently uses high-band networking, and the higher the frequency of radio waves, the shorter the wavelength, the weaker the diffraction (diffraction effect) capability, and the greater the signal penetration loss , so in urban areas with dense buildings, to achieve full coverage, the base station density is higher than that of low-frequency bands. Taking China Mobile as an example, the base station density of its TD-LTE network is at least 1.5 times greater than th...

Problems solved by technology

[0003] The traditional PCI planning method mainly uses manual and auxiliary tools, or the planning data only relies on map data, the accuracy is not satisfactory, and it is easy to cause unsatisfactory results due to manual defects or lack of experience. The present invention is under such a background. Combining prior knowledge in the field of communication with knowledge in the computer field to achieve efficient and accurate PCI planning

[0004] In the process of research and practice of the existing technology, the inventor found that there are at least the following problems in the existing technical solution: only compatible with some equipment manufacturer data, single planning data source, complex data format requirements, and multiple data cannot be jointly analyzed and corrected At the same time, the planning method and process are relatively complicated, not easy to operate, and are insufficient for high-intensity network and regional planning and response speed. The above reasons limit the application range of existing technical products, and the effect of planning is also limited. influence, and the present invention just well solves the above problems
