The present invention provides a method for reestablishing a radio resource control connection and a base station, wherein the method includes: the base station detects whether the data transmission between the base station and the user equipment is normal; when the data transmission is abnormal, the base station sends a signaling to the user equipment UE to Make the UE perform RRC connection re-establishment according to the signaling; the base station receives and processes the RRC connection re-establishment request sent by the UE. When the data transmission between the base station and the user equipment is abnormal, the present invention enables the base station to actively trigger the UE to initiate RRC connection reconstruction, avoiding data transmission interruption and reducing the impact on data transmission.

The embodiment of the present invention provides a service path protection method, controller, device, and system. The end node of the protection path receives the routing instruction sent by the SDN controller. The routing instruction includes the activation type of the service path and the protection path, and the service path. The forwarding relationship in the end node and the forwarding relationship of the protection path in the end node; the end node of the protection path activates the forwarding relationship of the service path in the end node according to the service path and the activation type of the protection path, and the protection path in the end node At least one of the forwarding relationships in the internal forwarding relationship; when it is determined that the service path fails, the end node of the protection path updates the forwarding relationship of the service path in the end node, and at least one of the forwarding relationship of the protection path in the end node Forward relationship. The embodiment of the present invention solves the problem that in the SDN technology, when the service path fails, the protection path cannot be used to protect the service path. Embodiments of the present invention relate to the technical field of communication.

An embodiment of the present application provides a method for realizing data transmission in a time-sensitive network, related equipment, and media. One of the methods includes: during the protocol data unit session management process of the user terminal, the session management function device reports to the centralized network controller Port management parameters, where the port management parameters include the identifier of the user terminal, the first port list provided by the device-side time-sensitive network converter connected to the user terminal, and the network connected to the user plane functional device The second port list provided by the time-sensitive network converter; the session management function device receives the port configuration parameters issued by the centralized network controller, and the port configuration parameters include ports associated with the protocol data unit session resource. The application can effectively solve problems such as transmission conflicts and poor configuration of ports, and ensure the smooth progress of the data transmission process of the time-sensitive network.
