A resource allocation method in wireless network virtualization

Abstract

The embodiment of the invention provides a resource allocation method in wireless network virtualization, which comprises the following steps of: issuing a plurality of contracts to user equipment (UE) according to request information aiming at target contents, so that a user can select the target contracts; constructing an optimization problem model according to the target contract; and solving the optimal solution of the optimization problem model, obtaining a caching strategy of the MVNO equipment for the target content and spectrum resources and computing resources distributed to the UE, and providing the target content for the UE according to the distributed spectrum resources and computing resources. The embodiment of the invention provides a resource allocation method in wireless network virtualization. An effective contract is designed for network nodes with selfish and information asymmetry. The contract is established between the MVNO and the user, the user expectation time delay is used as hidden information for measuring the service quality of the user, multi-dimensional resources are effectively distributed, reasonable and efficient utilization of the resources can beensured, and the MVNO and the user can obtain the maximum effectiveness.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technologies, and in particular to a resource allocation method in wireless network virtualization. Background technique [0002] The 5G network has the following three main application scenarios: Enhanced Mobile Broadband (Enhanced MobileBroadband, eMBB), Ultra-Reliable and Low Latency Communication (Ultra-Reliable and Low Latency Communication, URLLC) and Massive Machine Type Communication (Massive Machine Type Communication, mMTC). To meet the needs of different application scenarios and diversified business types of 5G, highly scalable, highly flexible, and programmable Network Virtualization (Network Virtualization) technology has emerged as the times require. Software Defined Network (SDN) is an implementation of network virtualization. Its core technology, OpenFlow, realizes flexible control of network traffic by separating the control plane and data plane of network...

[0004] However, as a self-interested entity, users may have deceitful behaviors in order to obtain greater benefits. In the prior art, the resource scheduling mechanism designed on the premise of knowing the actual wishes of users has the problem of information asymmetry between the two sides of the interaction caused by the selfishness of users. Thus affecting the reasonable scheduling of resources and the overall performance of the network
