Document Type and Number:
WIPO Patent Application WO/2018/126812
Kind Code:
A1
Abstract:
Provided in an embodiment of the present invention are a data transmission method and device. The method comprises: receiving data transmitted by a terminal in an inactive state, the data comprising data to be transmitted by the terminal and identifier information of the terminal; determining, according to the identifier information, an anchor base station of the terminal; transmitting the data to the anchor base station; transmitting the data to a core network apparatus by means of the anchor base station; and employing interaction between the anchor base station and a serving base station currently providing the terminal with an air interface resource to forward, by means of the serving base station, uplink data of the terminal to the anchor base station and to upload the same to a core network without requiring a context transfer, a switch between the core network and a base station, signaling and interface overheads, thereby enhancing data transmission efficiency.
