Industrial park 5G communication signal optimization method based on ultra-dense networking Technical Field The invention belongs to the technical field of communication and ultra-dense networking, and particularly relates to an industrial park 5G communication signal optimization method based on ultra-dense networking. Background With the deep deployment of 5G communication technology in industrial internet, intelligent manufacturing, intelligent park, etc., ultra Dense Networking (UDN) has become an important means for improving network capacity and coverage quality in industrial park. Ultra-dense networking enhances spectrum multiplexing efficiency and user access capability by densely deploying a large number of small base stations in a limited geographic area. The high-density network architecture has higher requirements on flexibility of base station deployment, reliability of a return link and instantaneity of resource scheduling, and the traditional static networking mode is difficult to respond quickly when the requirements of sudden business such as temporary large-scale activities or dynamic recombination of production lines are faced. Dynamic deployment mechanisms based on mobile base stations are an important research direction to address the above challenges. The dynamic deployment mechanism aims at reconstructing the local wireless coverage structure by a movable small base station in a short time to adapt to the changed traffic hotspot distribution. The introduction of the mobile base station not only involves frequent adjustment of the physical location, but also needs to solve the problem of dynamic backhaul with the core network synchronously. The existing scheme generally depends on a preset return path or a fixed relay node, and lacks the joint optimization capability of the coupling relation between the quality of the return link and the coverage benefits, so that the return link is easy to be blocked and the coverage efficiency is difficult to guarantee in a high-interference and multi-shielding industrial environment. In the prior art, when the problems of deployment and backhaul resource allocation of a mobile base station are processed, the problems that the base station position selection is based on experience rules or static simulation, the environment change cannot be sensed on line and the self-adaptive adjustment cannot be realized, the backhaul link allocation and the spectrum resource scheduling are often subjected to splitting treatment, the strong coupling characteristics among the three are not considered, the resource waste and the performance bottleneck are caused, an efficient on-line learning mechanism is lacking, the balance exploration and the utilization in a complex dynamic environment are difficult, and the cooperative maximization of the coverage gain and the backhaul stability is realized. Under the conditions of severe requirements on communication continuity, low time delay and high reliability of an industrial park, the problems restrict agile deployment capability and service quality of a 5G ultra-dense network, and a signal optimization method capable of integrating intelligent learning and joint optimization is needed.
