1. A data transmission method, comprising:
- receiving a create or update message of a PDP context or a bearer sent by a sending end, wherein the create or update message carries a quality of service parameter; and
determining, according to the quality of service parameter, whether user plane tunnel data of a bearer corresponding to the PDP context or a user plane tunnel data of the bearer can be encapsulated through a UDP-Lite protocol, and returning, to the sending end, a response message carrying determination result information, so that when the determination result information indicates that encapsulation can be performed through the UDP-Lite protocol, the user plane tunnel data of the bearer corresponding to the PDP context or the user plane tunnel data of the bearer will be encapsulated through the UDP-Lite protocol by the sending end.

Abstract
Embodiments of the present invention provide a data transmission method, a network element device and a communication system. The technical solutions provided in the embodiments of the present invention can encapsulate some services having a high packet error resilient into UDP-Lite protocol packets, which, compared with the prior art, omits check on loads of the messages, thereby significantly improving data transmission efficiency.
