C.5 Default handling of PUBLISH requests
34.229-13GPPInternet Protocol (IP) multimedia call control protocol based on Session Initiation Protocol (SIP) and Session Description Protocol (SDP)Part 1: Protocol conformance specificationRelease 16TSUser Equipment (UE) conformance specification
This procedure may occur within 3 seconds after a successful IMS registration.
NOTE: For sake of testability and to mitigate detrimental effect on non-IMS test cases, it is assumed that such PUBLISH request arrives at SS within 3 seconds of sending 200 OK for REGISTER.
The generic test procedure:
1 SS receives from the UE a PUBLISH request.
2 The SS responds to the PUBLISH request with a 503 Service Unavailable response carrying a Retry-after header field big enough to quench further publication traffic during test case execution.
