Embodiment Construction

[0034] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] see figure 1 , figure 1 It is a schematic diagram of the system scene of the present invention. The model consists of three parts, namely infrastructure providers (infrastructure providers, InP), mobile virtual network operators (mobile virtual network operator, MVNO) and service providers (service provider, SP). The infrastructure provider InP owns the infrastructure resources (for example, data center, wireless access network, and backhaul network), and the MVNO rents network resources from the InP, creates virtual resources according to the request of the service provider SP, and allocates the running virtual resources to SP, and finally the service provider releases virtual resources to provide users with specific end-to-end services (such as video, voice, games). After virtualization, resources in the InP (such as base statio...

Abstract

The invention relates to a network utility maximization virtual resource allocation method based on Lyapunov, and belongs to the technical field of mobile communication. The method comprises the following steps: calculating the frequency spectrum, computing resources and cache resources of a base station occupied by each user by using Lagrange coupling and KKT conditions; updating the queue stateinformation of the user within each time slot; and performing joint optimization on the virtual resource allocation and system stability so as to achieve the objective of network utility maximization.In view of the virtual resource allocation problem in a wireless network, and in order to ensure the system stability, the joint optimization is performed on the virtual resource allocation and system stability. The wireless frequency spectrum resource is used as the benefit, the backhaul link resources, the computing resources and the cache resources are taken as expenses. At the same time, thestability of the system queue and the difference of the users of different virtual service providers are considered at the same time, and the objective of network utility maximization is achieved at last. By adoption of the method, the average total benefit of the wireless virtual network can be maximized while guaranteeing the stability of the system queue.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and relates to a virtual resource allocation method for network utility maximization based on Lyapunov. Background technique [0002] At present, the research and development of 5G technical standards is in full swing. The general consensus reached by all parties on 5G is that after entering 5G, the communication scenarios will become diversified and complicated, and the communication between things will develop rapidly, greatly surpassing human Communication needs between people. It is obvious that the traditional cellular network and the "one size fits all" model can no longer meet the different needs of all walks of life for the network in the 5G era. In the future 5G system, the network will be further abstracted into "network slicing" to support the use of thousands of application cases, many user types and various applications. To meet the needs of widely varying use cases, t...
