Embodiment Construction

[0091] First, several concepts related to the embodiments of the present invention are explained.

[0092] UDP: User Datagram Protocol, user datagram protocol. UDP is a transport layer protocol, generally used in packet networks, and user data is transmitted based on a single UDP packet.

[0093] UDP-Lite: User Datagram Protocol Lite, a lightweight user datagram protocol. The check range of the checksum field of the UDP-Lite protocol can be changed, and it is suitable for voice or video services with a bit error rate greater than a threshold.

[0094] GTP: GPRS Tunnelling Protocol GPRS tunneling protocol provides a tunnel for the transmission of user data and signaling information between GSNs. The GTP protocol is defined for the Gn and Gp interfaces of the GPRS network and is a GPRS tunnel protocol. Including GTP control plane (GTP-C for short) and data transmission (GTP-U for short) protocols, allowing datagrams of multiple protocols between UMTS or GPRS backbone network SGSN, S...

Abstract

The embodiment of the invention provides a data transmission method, network element equipment and a communication system. Said method comprises: receiving a PDP context creation or update messages sent by a sending end, said creation or update messages carrying a service quality parameter of the PDP context; determining if the beared user plane tunnel corresponding to the PDP context can pass through UDP-Lite protocol for packaging, according to the service quality parameter, and returning a response message which carries the determination result to the sending end, so enabling the sending end to package the beared user plane tunnel corresponding to the PDP context through the UDP-Lite protocol, when the determination result information received being the user plane tunnel can pass through UDP-Lite protocol for packaging. technical solutions from embodiments of the present invention can package some business of high mispackage tolarence to be UDP-Lite protocol packets, reducing the message load calibration, significantly improving data transmission efficiency compared to the prior art.

Description

Technical field [0001] The present invention relates to wireless communication technology, in particular to a data transmission method, network element equipment and communication system. Background technique [0002] IPv6 (Internet Protocol Version 6, the sixth version of the Internet Protocol) technology has matured day by day, and more and more applications. At the same time, due to the increasing shortage of allocatable IPv4 (Internet Protocol Version 4) addresses, it is imperative for mobile broadband networks to support the evolution to IPv6. [0003] When the PS (Packet Switch, packet switching) domain core network of the mobile broadband network evolves to IPv6, for example, between SGSN (Serving GPRS Support Node, Service General Packet Radio Service Technology Support Node) and S-GW (Serving Gateway, Serving Gateway) Data transmission interface between MME (Mobility Management Entity) and SGSN, data transmission interface between S-GW and RNC (Radio Network Controller), ...
