All published ETSI deliverables shall include information which directs the reader to the above source of information. Foreword This ETSI Standard (ES) has been produced

19、by ETSI Technical Committee Access and Terminals (AT). The present document is part 3 of a multi-part deliverable. Full details of the entire series can be found in part 1 5. I n t rod uct ion The present document is the third part of a multi-part conformance test specification for SM-TE. The presen

20、t document contains a TTCN design frame work and the detailed test specifications in TTCN for SM-TE at the userhetwork interface. The reader of the present document should be aware of the fact that much of the ATS information is contained in ES 202 912-2 6 and is therefore only referred to here, ind

21、icating the relevant clauses in ES 202 912-2 6. ETSI 6 ETSI ES 202 912-3 VI .I .I (2003-02) 1 Scope The present document specifies the protocol conformance testing in TTCN for the Data Link layer in a Terminal Equipment implementing the Short Message Service (SMS) for PSTNASDN, UBS Protocol 1, accor

22、ding to ES 201 912 i at the userhetwork interface. Basic ISDN or PSTN call procedures apply in order to establish a circuit-switched band connection between such Terminal Equipment and an SM-SC. Tests for these procedures are outside the scope of the present document. UBS1 terminals send and receive

23、 Data Link messages in the voice-band connection using the FSK signalling as defined in EN 300 659-2 2 and ES 200 778-2 3. Tests for the Physical Layer of the FSK signalling are also outside the scope of the present document. Terminal Equipment implementing the Short Message Service (SMS) for PSTNAS

24、DN according to UBS Protocol 1 are required to implement the Transfer Layer according to TS 100 901 4. Using the Remote Single Layer Embedded Test Method (see ISO/IEC 9646-2 SI) for the UBS Protocol 1 Data Link layer, Transfer Layer messages appear here only as octet string parameters of Data Link l

25、ayer messages. Tests for the Transfer Layer are not within the scope of the present document. The Abstract Test Suite designed in the document is based on the test cases specified in tabular form combined with prose in ES 202 912-2 6. The following information can be found in this part, directly or

26、by reference (mostly to ES 202 912-2 6): - - The testing architecture; - The overall test suite structure; The test methods and PCO definitions; - The test configuration; - TTCN styles and conventions, - - - - The partial PIXIT proforma; - The design principles, assumptions, and used interfaces to t

27、he TTCN tester (e.g. ASPS); Information about the assumed services of the Physical Layer; Interrelationships and dependencies between timeout values; The TTCN.MP and TTCN.GR forms for the mentioned protocols tests. While ISO/IEC 9646-1 7 and ISO/IEC 9646-2 SI have been used as the basis for the test

28、 specification methodology, the ATS contained in the present document has been specified using TTCN-2+ (TR 101 666 lo). Two forms of the ATS are provided (see annex A): - - The TTCN Graphical form (TTCN.GR), The TTCN Machine Processable form (TTCN.MP). ETSI 7 ETSI ES 202 912-3 VI .I .I (2003-02) 2 R

42、 development A number of requirements are identified for the development and production of the TTCN test specifications for ES 201 912 i: A unique testing architecture and test method for testing all protocol layers and protocol variants. Uniform TTCN style and naming conventions, to improve TTCN re

43、adability. Using TTCN-2+ (TR 101 666 lo). This TTCN specification is feasible, implementable and compilable. Test cases shall be designed in a way for easily adaptable, upwards compatible with the evolution of the specifications and the future Releases. The test declarations, data structures and dat

44、a values shall be largely reusable. Minimizing the requirements of intelligence on the simulators and transfer capabilities of the lower testers, giving enough design freedom to the test equipment manufacturers. Considering that the TS Structure and Test Purposes in ES 202 912-2 6 have been designed

45、 and formulated in way that supports an easy and direct transition to TTCN: follow the constructions and namings in a tight and direct way. In order to fulfil these requirements and to ensure the investment of the test equipment manufacturers having a stable testing architecture for a relatively lon

46、g period, a unique testing architecture and test method are applied to the “SMS over fixed network“ protocol tests.
