Network coverage planning method and device of evolution communication system

Abstract

The invention provides a network coverage planning method and device of an evolution communication system. The method comprises the steps of: obtaining a theoretical coverage parameter of a single base station of the evolution communication system by using a link budget; obtaining the theoretical coverage parameters of the whole network of the evolution communication system by using network analogue simulation; calculating a reception level value of the evolution communication system in a same planning area under a wireless environment of the current network communication system by means of measurement and report data of a terminal in the current network communication system corresponding to the evolution communication system and the relation between the current network communication system and the reception level of the evolution communication system so as to estimate simulated actual measurement coverage parameters of the evolution communication system; and planning the coverage parameters of the whole network of the evolution communication system according to the theoretical coverage parameter of the single base station, the theoretical coverage parameters of the whole network and the simulated actual measurement coverage parameters. With the adoption of the invention, the network coverage plan is more accurate so that the network established is closer to an expected coverage target.

Problems solved by technology

[0002] In the network coverage planning of the existing evolutionary communication system, the main means of coverage planning is theoretical estimation and planning through link budget and system simulation. Many factors will cause the actual coverage effect of the theoretical coverage planning to fall short. To the expected goal, for example: complex wireless environment (trees, buildings, shading of large vehicles, refraction, etc.) , map accuracy, etc., there are inevitably errors

Moreover, the coverage planning guided by theory is carried out before the network is built, and its accuracy cannot be verified through actual tests. After the network planning and construction are completed, it is found that the planning does not meet the expected goals and it is necessary to pay a lot of money to revise the planning and design.

[0003] Therefore, in the current coverage planning of the evolved communication system, the coverage performance after network construction often fails to meet the expected goals, especially prone to the following situations: coverage shrinkage in individual areas after network construction, and weak coverage at the edge of areas that can be continuously covered in the original plan , the user drops many calls; or the depth coverage requirement cannot be met, and the proportion of the receiving level value reported by the terminal does not meet the expected requirement

These have greatly affected KPI indicators such as cell throughput, edge rate, and call drop rate. After the construction of the communication network is completed, it is costly to change the network coverage plan by modifying and supplementing the site, which is difficult to implement and poses a threat to network operation. bring adverse effects
