Transmission method and network device
摘要
說明書
S241. The first network node sends a fifth message to the first system based on the first message, where the fifth message is used to instruct the first system to retrieve the context information of the terminal device that is stored at the first system.
For example, the DU sends the fifth message to a CU via an F1 interface. After the CU receives the fifth message from the F1 interface, if the CU can find context information of the terminal device that is stored at the CU and can successfully resume the RRC connection of the terminal device based on the context information, and information carried in the fifth message, the CU resumes the corresponding configuration and the corresponding transmission resource of the terminal device.
Optionally, the fifth message may carry indication information used to indicate that the first network node has not completely retrieved a context of the terminal device. Further, optionally, the first system carries configuration information of the terminal device in first indication information based on the indication information. The configuration information is used by the first network node to re-establish a context of the terminal device.
S250. The first system retrieves, based on the fifth message, the context information of the terminal device that is stored at the first system.
S260. The first system sends first indication information to the first network node, where the first indication information is used to indicate that the RRC connection of the terminal device is successfully resumed or fails to be resumed.
