Transmission method and network device
摘要
說明書
It should be further understood that a difference from the processing performed when the terminal device resumes from the inactive mode in
S132. The first system sends a second message to the first network node based on the first message, where the second message is used to instruct the first network node to re-establish the context information of the terminal device, and the second message includes identification information of the terminal device.
Optionally, the first system includes at least one of a Packet Data Convergence Protocol layer function, a Service DataAdaptation Protocol layer function, and a Radio Resource Control layer function.
For example, after receiving a first message carried in the F1 interface message, a CU parses out content of the message, so as to determine that the first message is a message used by the terminal device to request to resume an RRC connection, and further resume the RRC connection for the terminal device. If the RRC connection of the terminal device can be successfully resumed, an F1 interface control plane message is sent to a DU, to instruct the DU to resume a context configuration for the terminal device, where the context configuration includes SRB and DRB protocol stack configurations, and establish SRB and DRB control plane and user plane transmission channels of an F1 interface connection.
