Description

System architecture and optimization method of self-organizing network

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a system architecture and an optimization method for an ad hoc network.

Background

With the rapid development of wireless communication technology, people continuously raise higher requirements for the capacity, transmission rate and the like of a communication system, a series of network capacity raising technologies and architectures are proposed, and most of the technologies utilize a multi-port antenna with strong spatial processing capability to realize higher capacity, such as an intelligent antenna, a large-scale array MIMO technology and the like. For a multi-port antenna to achieve high network capacity, matched antenna weights need to be configured for different network scenes, but when the number of antenna ports is too large, the weight configuration is very complex, and cannot be achieved at all based on a traditional manual weight configuration mode.

The rapid development of Self-Organized Network (SON for short) technology provides an effective method for solving the above problems, and the core idea is to reduce the traditional manual operation and reduce the operation and maintenance cost of Network operators through the automatic process at the stages of Network planning, deployment, optimization, maintenance and the like.

The prior related technologies are as follows: and storing the unit directional diagram data of the antenna as a static file in the base station, wherein the stored information comprises the name of an antenna manufacturer, the model of the antenna, the sub-frequency band of the antenna, the half-power angle of the antenna and weight information. And when the broadcast weight value needs to be configured, the controller sends the antenna information and the beam index. The base station side can read the corresponding weight information from the static file according to the received antenna index and the antenna information. However, the difference of the unit pattern data of the antennas of different antenna manufacturers is large, so that the parameter information of the antennas of different antenna manufacturers needs to be manually collected and matched, a large amount of management and maintenance work needs to be performed, and the parameter information of the antennas is difficult to accurately obtain.
