5G virtual access network mapping method in time delay sensing condition

Abstract

The invention relates to a 5G virtual access network mapping method in the time delay sensing condition and belongs to the technical field of mobile communication. According to the method, the difference between the arrivals of virtual network requests, the dynamic occupation and release of limited physical resources, and the difference between the service capabilities of network function virtualization servers are combined, and then a queue state transfer equation is established at a network functional virtualization choreographer and each network function virtualization server. Meanwhile, atwo-stage queue dynamic scheduling method is provided. Furthermore, the queue states of all queues in the system are sensed, so that the queue dynamic scheduling is carried out to meet the time delayrequirement. Moreover, the mapping is completed by taking a minimum mapping cost as a target. According to the 5G virtual access network mapping method, the mapping cost can be minimized, and the timedelay requirement of the system can be met.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and relates to a 5G virtual access network mapping method under delay perception. Background technique [0002] Mobile communication technology has developed rapidly since the 1980s. Nowadays, with the accelerated deployment of the fourth-generation mobile communication technology, people's demand for data services is getting higher and higher, and the capacity, speed, spectrum and other aspects are gradually unable to meet people's needs for the network. Therefore, the fifth-generation mobile communication system should be used And born. For the deployment of the fifth-generation mobile communication system, it is necessary to provide a new related technology for the communication network to provide greater throughput, lower delay, and higher reliability, and through Wireless Network Virtualization (Wireless Network Virtualization, Network Slicing (NS) technology implemented by WN...

Problems solved by technology

[0005] There are still many factors that are not considered in the existing mapping methods. First of all, the existing mapping methods only consider the research on related mapping methods for one virtual network request, which only guarantees the on-demand allocation of resources in each mapping and the mapping cost. Secondly, it does not take into account the differences in the arrival of virtual network requests for a period of time, the differences in service capabilities of network function virtualization servers, the queue status of system mapping requests, and the dynamic occupancy and consumption of physical resources from an overall perspective release, and does not consider how to meet the system delay requirements when a large number of virtual network requests arrive in a short period of time, so how to meet the system delay requirements while ensuring the minimum mapping cost during the mapping process is very worthy of research content
