Title:
USER DATA TRANSMISSION METHOD, NETWORK DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/017568
Kind Code:
A1
Abstract:
Provided in the present application are a user data transmission method, a network device and a storage medium. The user data transmission method comprises: receiving a first message sent by a second network device, wherein the first message comprises: downlink data transmission state information of a user plane interface; and managing at least one of the redundant data transmission function and the user plane interface according to packet loss information of uplink data of the user plane interface and/or the downlink data transmission state information of the user plane interface included in the first message; wherein the redundant data transmission function is a function of transmitting the same data copy on multiple user plane interfaces.
