9、 Q.3619 v.1 and IETF RFC 3264 in compliance with the relevant requirements and in accordance with the relevant guidance given in ITU-T X.296. This Recommendation can be used for compliance testing against ITU-T Q.3619 v.1 “Communication HOLD using IP multimedia core network subsystem Protocol specif

19、 this Recommendation is to test the signalling and procedural aspects of the stage 3 requirements as described in ITU-T Q.3619 v.1. Stage 3 describes the requirements for several network entities and also the requirements for terminal devices. Therefore several interfaces (reference points) are addr
20、essed to satisfy the test of the different entities. Therefore to test the appropriate entities the configurations below are applicable. 4.1.2 Testing of the UE There are special clauses in the protocol standard describing the procedures that apply at the originating and terminating user equipment (
21、UE). Therefore the test configuration below has been chosen. Figure 2 Applicable configuration to test UE functionalities Rec.
