A virtualized wireless network function orchestration policy

Abstract

The invention provides a virtualized wireless network function arrangement strategy which is helpful for reducing the rejection rate of an Internet of Things access service and improving the utilization rate of network system resources, and comprises the following steps: S1, establishing a virtualized wireless network resource arrangement chemical reaction optimization mathematical model; and S2,solving the mathematical model established in the step S1, which comprises improving the local optimization capability of the CRO based on Gaussian disturbance, balancing the global and local search capability based on a random walk method, and improving the search capability and search speed of the global approximate optimal solution of the CRO based on reinforcement learning. The method has thebeneficial effects that the rejection rate of the Internet of Things access service is reduced, the utilization rate of network system resources is improved, the solving speed of the global approximate optimal solution is increased, the approximation degree of the approximate optimal solution is improved, and finally, the automation and intellectualization process of the virtualized network is accelerated.

Description

technical field [0001] The invention belongs to the field of mobile communication, in particular to a resource arrangement method for a virtualized network slice of a wireless mobile communication network. Background technique [0002] With the development of network technology, the communication network no longer only satisfies the communication between people, but extends to the communication between people and things, and between things. However, the performance indicators of network requirements for different communication methods vary greatly. All kinds of businesses hope to have a vertical proprietary network to provide services. For example, the Internet of Vehicles for autonomous driving needs to provide real-time and highly reliable services, while monitoring the Internet of Things requires low-bandwidth and ultra-massive connections. With the emergence of ever-changing applications and the increasing demand for the Internet of Everything, access methods and networ...
