19、 Test configurations 4.1 Introduction Test purposes of the present document address the VoLTE functional entity MME that is accessible via the standardized S1-MME interface. 4.2 Test configuration using the S1-MME interface The S1-MME interface is located between the eNB and the MME. The NAS message
20、s are transparent for the eNB, therefore only the MME is considered a System Under test (SUT).

26、cit requirements for testing, the TPs were generated as a result of an analysis of the base standard and the PICS specification ETSI TS 103 530-1 2. 5.1.3 TP structure Each TP has been written in a manner which is consistent with all other TPs. The intention of this is to make the TPs more readable
27、and checkable. A particular structure has been used which is illustrated in table 2. Table 2 should be read in conjunction with any TP, i.e. please use a TP as an example to facilitate the full comprehension of table 2.

DOWNLINK_NAS_TRANSPORT) written with underscore character and NAS messages (ex. ATTACH REQUETS) with space character. NOTE 3: An IE can be embedded into another IE. This i
