Title:
DATA TRANSMISSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/159829
Kind Code:
A1
Abstract:
Disclosed are a data transmission method and apparatus. The principle of the method is: establishing two tunnels between an access network device and a user plane function network element, wherein the two tunnels may be tunnels used for downlink data transmission, or tunnels used for uplink data transmission. When an access network device and a user plane function network element are in communication, two data packets can be transmitted, such that where one data packet is lost, a receiving end can also receive the other data packet, thereby improving the reliability of data transmission.
