Network planning and optimizing method based on bandwidth reservation and device

Abstract

The invention discloses a network planning and optimizing method based on bandwidth reservation and a device. The network planning and optimizing method based on bandwidth reservation comprises the steps of obtaining the bandwidth required by a service of each pixel area within the covering area of each base station of a network to be planned, wherein each pixel area is a small area planned for each base station of the network to be planned; calculating the reserved bandwidth of each base station, wherein the reserved bandwidth of each base station is obtained by equivalent calculation of the bandwidth required by the service of each pixel area within the covering area of a neighbor base station of the base station in proportion; using the calculated reserved bandwidth as a disturbing influence index of a corresponding base station, and carrying out network planning calculation according to the disturbing influence index, a preset planning algorithm and a constraint algorithm to accomplish the planning of base stations in the network to be planned. According to the network planning and optimizing method based on bandwidth reservation and the device, due to the fact that the reserved bandwidth is calculated to simulate the disturbing influence, network planning and optimization can be achieved accurately.

Description

technical field [0001] The invention relates to the field of communication network planning and optimization, in particular to a network planning method, optimization method and device based on bandwidth reservation. Background technique [0002] With the continuous expansion of the scale of mobile communication networks and the development trend of miniaturization of base stations, the number of network elements to be maintained by operators is increasing rapidly, and the required maintenance costs are also increasing. The self-organization network (self-organization network, SON) proposed in December 2006 hopes to achieve the purpose of saving operating costs by realizing as much automation as possible in the planning, deployment, and operation and maintenance stages of the mobile communication network. [0003] The self-optimization of SON is based on the analysis of the impact of network interference and the optimization goal of network performance, that is, the network ...

AI Technical Summary

Problems solved by technology

[0004] However, for network planning, since the actual communication network has not yet been deployed, it is difficult to obtain the SINR of the network as an indicator of interference impact. Usually, some statistics or rough estimates are used, and the accuracy is difficult to guarantee

For network optimization, because the communication system is very complex, the interference relationship between network elements is also relatively complicated, which also makes it difficult for existing network optimization methods that rely on interference management to accurately obtain optimized configurations for optimization.
