Title:
DATA TRANSMISSION METHOD AND DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/166284
Kind Code:
A1
Abstract:
The present invention provides a data transmission method and device, and a storage medium. The method comprises: encapsulating, at a GTP-U layer, data transferred between a CU and a DU into a GTP-U data packet; generating a User Datagram Protocol (UDP) header of the GTP-U data packet, and encapsulating the GTP-U data packet and the UDP header at a UDP layer to form a UDP data packet; and generating an IP header of the UDP data packet, encapsulating the UDP data packet and the IP header at an IP layer to form an IP data packet, and transmitting the IP data packet. By transmitting the data between the CU and the DU using the solution above, the occurrence of out-of-order and packet loss of the data is reduced, call drop during conversation of a mobile client is reduced, and the communication quality is improved.
