20、the stage 3 requirements as described in ITU-T Q.3619 v.1. The stage 3 description respects the requirements to several network entities and also to requirements regarding end devices. Therefore several interfaces (reference points) are addressed to satisfy the test of the different entities. Theref

21、ore to test the appropriate entities the configurations below is applicable: Testing of the network: This entity is responsible to perform the service. In case only the Gm interface is accessible this shall be used instead. In this case, be aware that the verification of several requirements is impe
