3、Access and Terminals (AT). The present document is part 2 of a multi-part deliverable. Full details of the entire series can be found in part 1 SI. ETSI 6 ETSI ES 202 912-2 VI .I .I (2003-02) 1 Scope The present document provides test suite structure and test purposes for testing Data Link layer in

4、a Terminal Equipment implementing the Short Message Service (SMS) for PSTNASDN, UBS Protocol 1 according to ES 201 912 i. 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 out

5、side the scope of the present document. UBS1 terminals send and receive Data Link messages in the voice-band connection using the FSK signalling as defined in EN 300 659-2 3 and ES 200 778-2 6. Tests for the FSK signalling are also outside the scope of the present document. Terminal Equipment implem

6、enting the Short Message Service (SMS) for PSTNASDN according to UBS Protocol 1 are required to implement the Transfer Layer according to TS 100 901 7. Using the Remote Single Layer Embedded Test Method (see ISO/IEC 9646-2 lo) for the UBS Protocol 1 Data Link layer , Transfer Layer messages appear h

7、ere only as octet string parameters of Data Link layer messages. Tests for the Transfer Layer are not within the scope of the present document. Figure 1 gives an overview of the reference architecture used for the UBS Protocol1 operation. Figure 2 shows the configuration used for testing. ISO/IEC 96

8、46-1 9 and ISO/IEC 9646-2 lo are used as the basis for the test specification methodology. 2 Re fe re nces The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

18、 DL-Initiator: entity (SM-TE or SM-SC) initiating a data link connection to the peer entity by sending a DL establishing message (after the VB-connection has been established) DL-Responder: entity (SM-TE or SM-SC) having received a DL establishing message from the peer entity (after the VB-connectio

19、n has been established) incoming VB-connection: VB-connection initiated by an SM-SC inopportune behaviour (of the tester): the tester sends a message which is not expected by the IT under the current circumstances (state) invalid behaviour (of the tester): abbreviated form of “syntactically invalid

20、behaviour“, i.e. the tester sends a message where the presence or contents of one or more parameters or fields does not conform to the requirements originator (of an SM): SM-TE sending an SM to another SM-TE outgoing VB-connection: VB-connection initiated by an SM-TE peer (entities): SM-TE and SM-SC

21、 for which a voice-band connection exists or is pending SM-Call: incoming call for a SM-TE where the CLI contains the address of an SM-SC stored in the SM-TE valid behaviour (tests): tester behaves according to the protocol NOTE: Timeout tests normally belong to the valid tests. VB-connection: voice

22、-band connection between two peers NOTE 1 : A Voice-band connection is considered to be completed or established, when the basic call control procedures, performed according to the type of network access the SM-TE is connected to (i.e. PSTN or BRA ISDN or PRA ISDN), are completed and the voice-band

23、connection is ready for FSK frame transfer. NOTE 2: In order to establish an incoming VB-connection, the CLI information has to be previously provided to the terminal equipment. The way of providing CLI (e.g. by DTMF or FSK signalling and using a data transmission associated with ringing or not, etc

24、, in the case of PSTN) is out of the scope of the present document . VB-Initiator: entity (SM-TE or SM-SC) initiating a voice-band connection to the peer entity VB-Responder: entity (SM-TE or SM-SC) having received a voice-band connection attempt from the peer entity ETSI 8 SM-TE (Initiator) ETSI ES

25、 202 912-2 VI .I .I (2003-02) Network SM-SC (PSTNIISDN) (store optional, .e. not present PL lin all DLL messages The short field names in table 13, e.g. MT, are the abbreviated field names as they appear in DLL messages occurring in test behaviour descriptions, when appropriate. NOTE 1: Clause 5.3.2

26、 of ES 201 912 i specifies also the “Mark signal“ and the “Checksum“. Both message elements do not appear in the message structure definition used in the present document, but are treated in the ASPS used for DLL message transmission and reception. The following principle applies for messages to be

27、transmitted by the tester: The Message type field is not shown explicitly, because it is identified by the message name. If the Extension bit is not shown explicitly, it is understood that the bit value “1“ (no segmentation) is sent. The Message length is not shown explicitly, the contents of the Me

28、ssage length octet is the binary coding of the number of octets in the payload. If the Payload is not shown explicitly, it is omitted. If the Payload is shown explicitly, it refers to a Test Parameter (see table 14 on page 19) to be transmitted. The following principle applies for messages to be rec

29、eived from the IUT: The Message type field is not shown explicitly, because it is identified by the message name. If the Extension bit is not shown explicitly, it is understood that the bit value “1“ (no segmentation) has to be received. The Message length is not shown explicitly. The contents of th

30、e received Message length octet has to be the binary coding of the number of octets in the payload (otherwise the message is not passed to the LT by the LTS). If the Payload is not shown explicitly, it is assumed that no Payload has to be received in this message. If the Payload is shown explicitly,

31、 it either refers to a Test Parameter (see table 14 on page 19), or it explicitly indicates “OMIT“, or it indicates one of the wildcards Any (?) or AnyOrOmit (*). NOTE 2: The wildcards Any and AnyOrOmit and their symbols ? and * have been borrowed from TTCN and have the same semantics: ? means that

32、any non-empty value compatible with the type of the referred field is received, * means that either nothing is received, or any non-empty value compatible with the type of the referred field is received. ETSI 19 EXAMPLES : ! DLL-SMS-E ST ETSI ES 202 912-2 VI .I .I (2003-02) 6.5 A correct DLL-SMS-EST

33、 message is sent, without payload !DLL-SMS-DATA (PL=TSPX-SMS-DELIVER-S 1) A syntactically correct DLL-SMS-DATA message is sent, with the Payload represented by Test Parameter TSPX-SMS-DELIVER-S l, which contains a default TL SMS-DELIVERY message. ?DLL-SMS-DATA (E=l, PL=?) A syntactically correct DLL

34、-SMS-DATA message is received, where the extension bit is set to “1“ (i.e. “no segmentation“), and the Payload is any octet string of length up to 176 octets. Behaviour notation This clause describes the principles used when filling the “Test description“ entry of the TP tables (see sample in clause

35、 5.7) and the behaviour notation of preambles and postambles. The notation used to describe the trees containing the required operations and signalling control primitives, is a TTCN- like notation, showing what is sent (character !) and received (character ?) by the tester (playing the role of the S

36、M-SC). ASPs are sent as shown in the following TTCN-like form: O!OUTGOING-CALL-req where O denotes the PCO used with the ASP, ! denotes “transmission“ and the ASP name follows. Since default values have been defined for the ASP parameters, parameter values are only indicated when they differ from th

37、e default value. EXAMPLE 1: In this case 2 SMs are requested to be transmitted by the SM-TE during the VB connection (instead of default 1 SM to be transmitted). The same principle applies for received ASPs, the symbol ! being replaced by ?. EXAMPLE 2: CC?OUTG-CALL-ind In this case the LT receives a

38、n indication from the LTS that there is an incoming call from the SM-TE (being requested at the SM-TE as in example 1). There is one important exception for the presentation of ASPs: To increase the readability, ASP names TRANSFER-req and TRANSFER-ind are not shown, except when a DLL message is to b

39、e transmitted with an error in the “Mark signal“ or the “Checksum“. DLL message names are directly used instead for transmission and reception. For examples see clause 6.4.2. When the tester expects a reaction from the IUT following the transmission of a PDU or ASP, the start of an “acknowledgement

40、timer“ is assumed, but normally not indicated in the test description. Notes are put into the behaviour descriptions whenever it appears to be necessary. Preambles and Postambles: The description of Preambles and Postamble starts with an Objective definition. ETSI 20 ETSI ES 202 912-2 VI .I .I (2003

41、-02) Test Parameter name The behaviour description ends with the preamble or postamble name. Between start and end the notation is as described above for “Test description“. Each preamble shows the state from where it starts (idle or a different state reached by the execution of another preamble), t

42、hen it shows the operations executed in this preamble and fially the state or configuration reached, using the notation described above. Type Description Each test purpose description shows the state from where it starts by identiSling a preamble. TSPX-SMS-DELIVER-S3 TSPX-S MS-SU B MIT-REP-ACK TSPX-

Test Parameter names starting with “TSPX“ are used for

44、 test parametrization and will correspond to PIXIT items, TS Parameter names starting with “TSPC“ are used for selection and normally correspond to PICS items. Only Test Parameters referred to in the TP description tables appear here. It is assumed that the Test Parameters defied here will be transf

45、ormed into TTCN “Test Suite Parameters“ in an ATS basing on this TSS&TP, presumably in a one-to-one fashion. Table 14 shows the Test Parameters that are necessary to parameterize the test descriptions to the necessary extent. They will normally appear as ASP parameter values or PDU field contents. I

46、t is also possible that they appear in I brackets as qualifiers for different branches of behaviour (see clause 6.5).
