Embodiment Construction

[0091] First, several concepts involved in 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, Lightweight User Datagram Protocol. The check range of the checksum field of the UDP-Lite protocol can be changed, which is applicable to voice or video services whose bit error rate is greater than the threshold.

[0094] GTP: GPRSTunnellingProtocolGPRS tunnel 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) protocol, allowing datagrams of multiple protocols between SGSN on UMTS or GPRS backbone network, ...

Abstract

The embodiment of the invention provides a data transmission method, network element equipment and a communication system. The method comprises the steps that a PDP context creating or updating message transmitted by a transmitting end is received, and the creating or updating message carries PDP context service quality parameters of a PDP context; and whether a bearing user plane tunnel corresponding to the PDP context can be packaged through a UDP-Lite protocol is judged according to the service quality parameters, and a response message carrying judgment result information is returned to the transmitting end so that the bearing user plane tunnel corresponding to the PDP context is packaged through the UDP-Lite protocol when the transmitting end receives the judgment result information indicating that packaging through the UDP-Lite protocol can be performed. According to the technical scheme, business of high wrong packet tolerance can be packaged into messages of the UDP-Lite protocol so that verification of the load of the messages can be reduced and data transmission efficiency can be substantially enhanced in comparison with the methods in the prior art.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a data transmission method, network element equipment and a communication system. Background technique [0002] IPv6 (InternetProtocolVersion6, the sixth edition of the Internet Protocol) technology has matured day by day, and there are 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] After the PS (PacketSwitch, 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, serving gateway) , the data transmission interface between MME (MobilityManagementEntity, mobility management...
