Communication method, equipment and system

Abstract

An embodiment of the invention discloses a communication method. The communication method is used for defining the signaling interaction flow between a central unit and a distribution unit. The method includes: the distribution unit receives a wireless link building request transmitted by the central unit, wherein the wireless link building request comprises resource information for building a wireless link; the distribution unit builds the wireless link according to the resource information; the distribution unit transmits the wireless link building response to the central unit.

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication method, device and system. Background technique [0002] Traditional telecommunication networks, especially wireless communication networks, such as Global System for Mobile Communication (GSM) and Universal Mobile Telecommunications System (UMTS), have the advantages of rich business types and strong network control capabilities. However, due to factors such as limited frequency resources and harsh transmission environments, wireless communication systems cannot provide high access rates, and emerging broadband wireless access technologies make up for these shortcomings. Broadband wireless access technologies represented by Wireless Local Area Networks (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX) can provide high-speed broadband wireless access services and support nomadic and mobile application, greatly improving the access capability of ...

Problems solved by technology

[0005] The evolution of Radio Access Network (RAN) can be divided into central unit (Central Unit, CU) and distributed unit (Distributed Unit, DU); users access the core network through CU and DU to perform service access; however, specific What functions are included in the CU / DU, and the interface protocol stack and process are not defined

The disadvantages of the existing technology are that the network architecture of the next-generation network is not clear, and the functions of CU and DU are not clear.
