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

The test cases are expected to be executed through the 3GPP radio interface. Details of the radio interfaces are outside the scope of this specification. The reference environments used by tests are specified in the test.

5.1 Generic setup procedures

A set of basic generic procedures for PDP Context Activation, P-CSCF Discovery and Registration are described in Annex C. These procedures are used in numerous test cases throughout the present document.

5.2 Transport protocols applied

For simplicity, UDP (User Datagram Protocol) is applied to the IMS test as default DL transport protocol.

NOTE: Which UL transport protocol is used in the test is decided by the UE.
