34、e describes the ATM used to test ETSI TS 129 274 1. 4.2 Test architecture 4.2.1 Test method The S11 interface is located between the MME and the S-GW. The test method chosen is the remote test method. Remote test method means that the test tool (the test machine + the executable test suite) shall be

35、have as an MME when the IUT is an S-GW and shall behave as an S-GW when the IUT is an MME. As the exchange between the test system and the IUT is at the GTPv2-C message level, the lower layers of the test machine shall be totally conformant with the corresponding lower layers specifications to use t

36、he remote test method.
