Transmission method, transmission system and service gateway for error indication parameters in response message

Abstract

The invention discloses a transmission method, a transmission system and a service gateway for error indication parameters in a response message. The method comprises the following steps that: an intermediate node receives a first response message fed back by a lower layer node; the intermediate node marks the error indication parameters and generation nodes of the error indication parameters in a second response message fed back to an upper layer node when determining that the error indication parameters are carried in the first response message; and the intermediate node feeds back the second response message to the upper layer node. The use of the invention, if processing error is indicated in the response message, can ensure that a final node can know on which nodes finally received errors occur after receiving the corresponding response message, thereby solving the problem that no similar solving mechanism exists in the prior protocols of core networks, and ensuring that network nodes can correctly execute error processing.

Description

technical field [0001] The invention relates to the field of communication, in particular to a transmission method, system and service gateway of an error indication parameter in a response message. Background technique [0002] In the current EPS (Evolved Data Network System) system, messages processed by the same protocol may be processed by multiple nodes before reaching the final destination. These intermediate nodes do not simply forward messages, but need to save and understand the parameters in the messages. In this case, both the intermediate node and the final destination node may cause a processing error due to a problem in processing the message. However, in the current core network, in the response received by the node that sent the initial message, there are only the error cause parameters of the intermediate processing node that directly sends the response back. [0003] For example, the tunnel management message of GTP (GPRS Tunneling Protocol, GPRS Tunnelin...

AI Technical Summary

Problems solved by technology

[0011] The present invention provides a transmission method, system and service gateway for error indication parameters in a response message to solve all, two or two problems in the core network. When more than one interface uses the same protocol and completes the message forwarding process through the intermediate node, it can correctly indicate the error occurred and the node where the error occurred.
