Title: DATA TRANSMISSION METHOD, NETWORK DEVICE AND TERMINAL DEVICE
Abstract:
The present application relates to the technical field of communications, and particularly relates to a data transmission method and a network device. The method of the present application comprises: a first network device determining that a terminal device has entered an RRC deactivation state; the first network device sending a first message to a second network device, the first message being used for configuring the second network device to make the second network device transmit data for the terminal device in an RRC deactivation state; and the first network device receiving an acknowledgement message of the first message sent by the second network device. In the present application, the second network device transmits the data of the terminal device to the first network device to make the first network device send the data to a core network and a path does not need to be established between the second network device and the core network to enable the second network device to send data to the core network, thus reducing signalling overheads in the whole process of the terminal device sending data to the core network.
