Access and Terminals (AT); Short Message Service (SMS) for PSTN/ISDN; Test Suites for SMS User Based Solution; Part 10: Abstract Test Suite (ATS) user side for functional tests Protocol 2 (V1.1.1)
"The present document specifies the functional tests in TTCN for the Transfer Layer in a Terminal Equipement implementing the Short Message Service (SMS) for PSTN/ISDN@ UBS Protocol 2@ according to ES 201 912 [1] at the user etwork 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. UBS2 terminals send and receive TL messages in the voice-band connection using the FSK signalling as defined in EN 300 659-2 [2] and ES 200 778-2 [3] and DLL services defined in clause 6 and annex B of ES 201 912 [1]. Tests for the Physical Layer of the FSK signalling are outside the scope of the present document. Tests for the DLL of USB 2 terminal have been defined in ES 202 912-5 [5]. Terminal Equipment implementing the Short Message Service (SMS) for PSTN/ISDN according to USB Protocol 2 are required to implement the Transfer Layer according to clause 6 and annex B of ES 201 912 [1]. Transfer Layer messages used in this test specification are structed accordingly. As the term 'functional tests"" indicates@ the present document is no conformance test specifiation: a comprehensive coverage of functions and TL protocol features is not attempted. Only the main functions and TL procedures related to outgoing SM-calls (from the SM-TE) and incoming SM-calls (to the SM-TE) are tested. The Abstract TestSuite designed in the document is based on the testcases specified in tabular form combined with prose in ES 202 912-9 [6]. TheRemote Single Layer Embedded Test Method (see ISO/IEC 9646-2 [8]) is applied for the UBS Protocol 2 functional tests. - The overall test suite structure. - The testing architecture. -The test methods and PCO definitions. - The testconfiguration. - TTCN styles and conventions. - The design principles@ assumptions@ and used interfaces to the TTCNtester (e.g. ASPs). - Information about the services assumed from the Data Link Layer and the Physical Layer. -Interrlationships and dependencies between timeout values. - The partial PIXIT proforma. - The TTCN.MP and TTCN.GR forms for the mentioned protocols tests. While ISO/IEC 9646-1 [7] and ISO/IEC 9646-2 [8] have beenused as the basis for thetest specificationmethodology@ the ATS contained in the present document has been specified using TTCN-2++9TR 101 666 [9]). Two forms of the ATS are provided (see annex A): - The TTCN Graphical form (TTCN.GR)@ - The TTCN Machine Processable form (TTCN.MP)."
