Resource optimized distribution method for wireless power private network based on virtualization technology

Abstract

The invention relates to a resource optimized distribution method for the wireless power private network based on a virtualization technology, and belongs to the technical field of electric communication. The method comprises the following steps that 1) the virtualized wireless power private network which comprises a base station model, a user model and a channel model is established; 2) a Tabu algorithm is used to optimize the virtualized wireless power private network; and 3) an objective function is optimized according to different constrained conditions, and a result of the objective function is obtained. According to the invention, the wireless resource is made abstract according to the power service type and present resource condition on the basis of the network virtualized technology; an optimal problem model of resource distribution is obtained by abstracting factors including the integrated network cost, profit, service isolation constraint, backhaul capacity constraint and QoS constraint, a combined optimization problem is solved by Tabu search, and problems in resource distribution of the wireless power access network are solved under the condition that the service isolation and service quality are ensured.

Description

technical field [0001] The invention relates to a wireless power private network-oriented resource optimization allocation method based on virtualization technology, which belongs to the technical field of electric communication. Background technique [0002] The power distribution business has the characteristics of wide distribution, many communication points, poor working environment of communication equipment, various business types, large data upload volume, and high reliability and security requirements. The / 3G data channel bears the power business and is converted to the power private network. Use the existing optical fiber resources of the power grid to build a power core network, and establish a TD-LTE-based wireless access network to realize the access of power terminal equipment. Among them, the access network is a wireless private network working in the 230MHz frequency band. TD-LTE base stations are established, and Orthogonal Frequency Division Multiplexing (...

AI Technical Summary

Problems solved by technology

However, there are still the following problems in the current power grid: 1. A large amount of wireless resources are wasted; 2. Interference between different services; 3. Lack of providing differentiated services for services with different QoS requirements

Although the invention patent application is in a multicast system wireless resource optimal allocation method based on the active antenna array model, the invention patent application does not consider the particularity of the power wireless private network (the power wireless private network must not be interfered, It should also not interfere with other networks, and at the same time have confidentiality), this algorithm is not suitable for power wireless private network

[0006] To sum up, the wireless power private network at the present stage only achieves the purpose of maintaining communication, and there is no effective method for resource control allocation, and the existing methods have various problems and cannot serve the purpose well. The wireless power private network performs resource allocation work, so there is an urgent need for a feasible method to integrate and redistribute resources for the wireless power private network
