18、of the stage 3 requirements as described in ETSI TS 124 610 1. The stage 3 description respects the requirements to several network entities and also to requirements regarding to end devices. Therefore several interfaces (reference points) are addressed to satisfy the test of the different entities.
19、 Therefore to test the appropriate entities the configurations below are 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
