Wireless communication networking method

Abstract

The invention discloses a wireless communication networking method. The method includes the steps of distributing HPNs in an area providing service, arranging at least two fog remote radio heads (F-RRHs), conducting communication through a mode of directly having access to the HPNs when the movement speed of a user terminal is larger than a preset threshold value M1 or real-time voice service communication needs to be conducted, conducting communication through a local F-RRH mode when the movement speed of the user terminal is smaller than or equal to the preset threshold value M1 and the distance between the user terminal and a user terminal to be in communication with the user terminal is larger than a preset threshold value D1 and is smaller than or equal to a preset threshold value D2, and conducting communication through a global BBU pool mode when the movement speed of the user terminal is smaller than or equal to the preset threshold value M1 and the distance between the user terminal and the user terminal to be in communication with the user terminal exceeds the preset threshold value D2. By means of the method, the requirement for the capacity of fronthauls can be lowered, the signal processing pressure on a BBU pool in a cloud computing service can be lowered, and the transmission delay can be prolonged.

Description

technical field [0001] The present application relates to the field of access network technology of wireless communication technology, and in particular to a wireless communication networking method. Background technique [0002] At present, with the increase in the number of mobile user terminals around the world and the improvement of the quality of service requirements of user terminals, the mobile user terminals are required for many intelligent and multimedia applications of high-speed data (such as: wireless high-definition video, social networking and point-to-point instant messaging, etc.) Demand is growing exponentially. According to statistics, in the next five years, the average daily total data volume of mobile services will increase from 186 terabytes (TB) in 2010 to 12,540 TB, which means that the average area capacity of the mobile communication system needs to be increased by at least 1000 TB compared with the existing mobile communication system. times. At...

Problems solved by technology

These data flows need to be transmitted to the cloud computing server in a detour, resulting in a surge in the amount of data transmitted on the forward link (Fronthaul) connecting the BBU pool in the cloud computing server and the RRH, and a large amount of redundant business and control information that does not need to be transmitted leads to The limited capacity of the forward link also increases the signal processing burden of the BBU pool in the cloud computing server. The longer transmission delay and processing delay lead to the limitation of large-scale centralized collaborative signal processing gain, which seriously affects H-CRAN. network performance

[0007] In addition, for H-CRAN, the user terminal access and handover technology in the prior art also has defects. Since the HPN and LPN exist at the same time, the mobile user terminal faces the problem of whethe
