A Distributed User Access Method

Abstract

The invention discloses a distributed user access method, and belongs to the technical field of wireless access networks. The distributed user access method comprises the following steps: firstly, each to-be-accessed user separately performs non-cooperative performance evaluation with accessable nodes to determine a potential user type; then, the user performs initial access, and calculates a rate gain and a necessary cost; the above information is broadcasted to F-AP nodes in the vicinity; and finally, each F-AP node calculates a utility function and an average utility function of each user according to the broadcasted information, performs iteration on the access selection of each user, and performs fine tuning switch on the communication mode. According to the distributed user access method disclosed by the invention, in view of high transmission delay, limited Fronthaul capacity and other problems of the traditional user access method, the influence of the transmission rate and the delay are comprehensively considered by making full use of the storage ability and the data processing ability of a network edge device; and the compromise between the own performance of the user and the overall performance of the network can be quickly achieved, the limited trip link capacity is greatly relieved, the data transmission delay is shortened, and the user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of wireless access networks, in particular to a distributed user access method of a wireless access network combining edge cloud computing and centralized cloud computing. Background technique [0002] In recent years, with the rapid development of wireless communication technology, mobile users' demand for many social applications and location-based communication applications of high-speed data has grown exponentially; such as wireless high-definition video, social instant messaging and online games. [0003] Under the network architecture of the existing centralized cloud computing wireless access network, these data flows need to be transmitted back to the cloud computing server for centralized processing, resulting in the connection between the baseband processing unit (BBU) pool and the remote network in the cloud computing server. The amount of data transmitted on the forward link (Fronthaul) between r...

Problems solved by technology

[0006] However, facing the large-scale deployment of network edge devices, users are faced with the problem of how to choose access methods

In addition, for different users, there are differences in the cache location information of required files, file transmission delay, and user business service quality requirements. Different access methods will make the performance of different users different. There is mutual influence, and the traditional user access technology is still lacking in research on optimizing access among multiple users
