Embodiment Construction

[0033] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] 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, radio 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 stations)...

Abstract

The invention relates to a Lyapunov-based virtual resource allocation method for network utility maximization, which belongs to the technical field of mobile communication. This method uses Lagrangian duality and KKT conditions to calculate the frequency spectrum, computing resources, and buffer resources of the base station occupied by each user; in each time slot, update the queue status information of the user; perform virtual resource allocation and system stability Joint optimization to achieve the purpose of maximizing network utility. The invention aims at the allocation of virtual resources in the wireless network, and simultaneously optimizes the allocation of virtual resources and the stability of the system in order to ensure the stability of the system. Taking wireless spectrum resources as income, and backhaul link resources, computing resources, and cache resources as expenses, and considering the stability of system queues and the differences of users of different virtual service providers, the purpose of maximizing utility is finally achieved. This method can maximize the average total revenue of the wireless virtual network while ensuring 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 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 the human-to-human communication. 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 ...
