Problems solved by technology

But now the CU and DU jointly manage the cells belonging to the base station. It is impossible to directly know which cells belong to which DUs and which DUs are managed by the CU, which affects the communication between the distributed base station and the terminal.
[0004] Aiming at the technical problem in the related art that affects the communication between the distributed base station and the terminal due to the inability to identify CU and DU in the distributed base station, no effective solution has been proposed yet

Embodiment 1

[0150] A method of communication such as figure 2 shown, including:

[0151] Step 201, the CU obtains the global cell ID of the designated cell;

[0152] Step 202, the CU queries the global DUID to which the global cell ID belongs in the locally saved first global ID list;

[0153] Step 203, the CU sends a first message to the corresponding DU according to the global DU ID, and the first message carries the global cell ID;

[0154] Wherein, the first global ID list includes the global CU ID of the current CU, the global DU ID of the DU belonging to the current CU, and the global cell IDs of all the cells belonging to the DU, and the global CU ID is used for global A CU is uniquely identified within a range, the global DU ID is used to uniquely identify a DU globally, and the global cell ID is used to uniquely identify a cell globally.

[0155] Through this embodiment, CU and DU can communicate with each other through the predefined global CU ID, global DU ID and global cel...

Abstract

The invention discloses a communication method and device, and the method comprises the steps that a CU acquires a global cell ID of a specified cell; the CU queries a global DU ID to which the globalcell ID belongs in a locally stored first global ID list; the CU sends a first message to a corresponding distributed processing network element DU according to the global DU ID, wherein the first message carries the global cell ID, and the first global ID list includes the global CU ID of the local CU, a global DU ID which belongs to the local CU, and global cell IDs of all cells belonging to the DU. The global CU ID is used to uniquely identify one CU globally, the global DU ID is used to uniquely identify one DU in a global scope, and the global cell ID is used to uniquely identify a cellglobally.

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication method and device. Background technique [0002] The 5G network architecture is innovative and flexible in networking. like figure 1 As shown, in the 5G network, the base station on the radio access network side is separated into two functional entities: a centralized processing unit (CU, Centralized Unit) and a distributed processing unit (DU, Distributed Unit). By controlling multiple DUs through the CU, the baseband centralized processing of the cloud architecture and remote distributed services for users can be realized. In the CU-DU separation architecture, the delay-insensitive network functions are placed in the CU, and the delay-sensitive network functions are placed in the DU, and the transmission and communication between the CU and the DU are performed through ideal / or non-ideal fronthaul. Connect to realize multi-point collaboration function, and c...
