(including directly transmitting and forwarding), receiving the process after response message as shown in Figure 4, Fig. 4 is this reality
Execute normal network element in the IMS faulty network element localization method of example and process the flow chart of error response message, this stream
Journey comprises the following steps:
Step S312: normal IMS network element receives the response message of mistake.
Step S314: normal IMS network element judges self to be whether the promoter of business request information, if
It is to perform step S316；If it is not, perform step S318.
Step S316: if this normal IMS network element is the promoter of business request information, then this normal IMS
According to response message, network element determines that business request information processes mistake, to occurring at the business of mistake
Reason.
Step S318: if this normal IMS network element is not the promoter of business request information, then normal IMS
Network element direct transparent transmission instruction IMS occurs the response message of network element mistake, until being pass-through to by response message
The normal IMS network element of initiating business request message.
Receive, after each network element of IMS sends business request information, the error response message that other network elements are sent,
If this normal IMS network element is not the promoter of business request information, self element name letter need not be increased
Breath, direct transmitted response message；By that analogy, until error response message sends to business request information
Promoter.
By step S312-S318, it is achieved that each network element, in Business Processing, receives other network elements and processes
