Access and Terminals (AT); Short Message Service (SMS) for PSTN/ISDN; Test Suites for SMS User Based Solution; Part 7: Test Suite Structure and Test Purposes (TSS&TP) user side for functional tests using Protocol 1 (V1.1.1)
The present document provides test suite structure and test purposes for Functional tests for a Terminal Equipment implementing the Short Message Service (SMS) for PSTNASDN@ UBS Protocol 1 according to ES 201 912 [1]. 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@ although some parameters related to these procedures are used (e.g. SME subaddressing). UBS1 terminals send and receive Data Link messages in the voice-band connection using the FSK signalling as defined in EN 300 659-2 [5] and ES 200 778-2 [8]. Tests for the FSK signalling are outside the scope of the present document. Tests for Data Link Layer have been treated in ES 202 912-2 [10]. Terminal Equipment implementing the Short Message Service (SMS) for PSTNASDN according to UBS Protocol 1 are required to implement the Transfer Layer according to ES 201 912 [1]. The Remote Single Layer Embedded Test Method (see ISO/IEC 9646-2 [13]) is used for the UBS Protocol 1 Transfer layer. Figure 1 gives an overview of the reference architecture used for the UBS Protocol 1 operation. Figure 2 shows the configuration used for testing. ISO/IEC 9646-1 [12] and ISO/IEC 9646-2 [13] are used as the basis for the test specification methodology.
