Embodiment Construction

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

[0092] UDP: UserDatagramProtocol, 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: UserDatagramProtocolLite, 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 the threshold.

[0094] GTP: GPRSTunnellingProtocolGPRS tunneling protocol, which 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 (abbreviated as GTP-C) and data transmission (abbreviated as GTP-U) protocol, allowing datagrams of multiple protocols to be between UMTS or GPRS backbone...

Abstract

Embodiments of the present invention provide a data transmission method, network element equipment, and a communication system. The method includes: receiving a creation or update message of a PDP context sent by a sending end, the creation or update message carrying a quality of service parameter of the PDP context; judging according to the quality of service parameter whether the user plane tunnel corresponding to the PDP context can pass The UDP-Lite protocol performs encapsulation, and returns a response message carrying the judgment result information to the sender, so that when the sender receives the judgment result information that can be encapsulated through the UDP-Lite protocol, the PDP context is updated through the UDP-Lite protocol. The corresponding bearer user plane tunnel is encapsulated. The technical solution provided by the embodiment of the present invention can encapsulate some services with high fault tolerance into UDP-Lite protocol messages, which reduces the verification of the message load and significantly improves the efficiency of data transmission compared with the prior art. efficiency.

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 edition 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, 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, the data transmission interface between SGSN (ServingGPRSSupportNode, service general packet radio service technical support node) and S-GW (ServingGateway) , Data transmission interface between MME (Mobility Management Entity, mobility management entity) and SGSN, data tra...
