Abstract

The embodiment of the invention provides a communication method and a network device. A CU (Centralized Unit) sends data transmission state report indication information to a DU1 (Distributed Unit), thereby indicating the DU1 to report data transmission state information with UE (User Equipment). The CU sends configuration information of the UE and the report data transmission state information with the UE reported by the DU1 to a DU2, so the DU2 obtains the configuration information of the UE the same as that of the DU1 and the report data transmission state information between the DU1 and the UE. The DU2 carries out data transmission with the UE according to the configuration information of the UE and the report data transmission state information between the DU1 and the UE. The UE is switched from the DU1 to the DU2, or a bearer of the UE under the DU1 is migrated to the DU2, and in the process, the UE is senseless, so the data transmission continuity is improved.

Description

technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular, to a communication method and network equipment. Background technique [0002] With the rapid development of wireless communication technologies, a new radio access technology (New Radio Access Technology, NR for short) appears after the Long Term Evolution (LTE for short) technology. [0003] In the NR system, the NR cell includes a distributed architecture and a centralized architecture. The distributed architecture includes a centralized entity unit (Centralized Unit, referred to as: CU) and multiple distributed entity units (Distributed Unit, referred to as: DU). , the CU can manage multiple DUs, and when the UE moves in the NR cell, it may need to switch from one DU to another DU in order to obtain better data transmission services; the centralized architecture is similar to the traditional LTE network architecture, and the NR base station management ...
