Abstract

The embodiment of the invention provides a communication method and device. The method comprises the steps: enabling a user terminal to determine that two pieces of uplink user plane data need to be sent through a first PDU session, and user plane security end points of the two pieces of uplink user plane data are located at a main base station and an auxiliary base station respectively; accordingto a first user plane security protection method between the user terminal and the auxiliary base station, performing security protection on uplink user plane data needing to be sent through the auxiliary base station to obtain first uplink user plane data; according to a second user plane security protection method between the user terminal and the main base station, performing security protection on uplink user plane data needing to be sent through the main base station; sending the first uplink user plane data to the auxiliary base station, and sending the second uplink user plane data tothe main base station. By adopting the embodiment of the invention, the user plane security between the user terminal and the main base station and between the user terminal and the auxiliary base station can be ensured, thereby ensuring the confidentiality and integrity of user plane data transmission.

Description

technical field [0001] The embodiment of the present application relates to the technical field of communication, and relates to a communication method and device thereof. Background technique [0002] With the development of communication technology, the fifth generation mobile communication (5 th -generation, 5G) came into being, the third generation partnership project (3 rd -generation partnership project, 3GPP) defines three main application scenarios of 5G, namely massive machine type communication (mMTC), ultra reliable & low latency communication (uRLLC) And enhanced mobile bandwidth (enhance mobile broadband, eMBB). Among them, the URLLC scenario can save time, improve efficiency, and save resources, and can meet low-latency, high-reliability connection services such as unmanned driving and industrial automation. [0003] In the URLLC scenario, see figure 1 The schematic diagram of the network architecture in the uRLLC scenario is shown. The user equipment (user...
