19、ndatory protocol between the Service Centre (SC) and the Mobile Switching Centre (MSC) below the transfer layer is specified by GSM; this is a matter of agreement between SC and PLMN operators. The present document specifies three approaches to the specification of protocol stacks of communication p

20、rotocols for the purpose of relaying short messages and alerts between Short Message Service Centres and Gatewayhterworking MSCs (GMSC) for the Short Message Service (SMS). One approach is based upon use of the complete OS1 reference model (see X.200), another approach is based upon the use of only

21、the lower three OS1 layers, and another approach is based upon the use of CCITT Signalling System No. 7 (see Q.700). Alternative protocol stacks are specified via ASN.l encoding rules (see X.208 and X.209). These alternative protocol stacks are examples for the implementation of the Short Message Re

22、lay Layer (SM-RL). The requirements placed upon the Short Message Relay Layer are briefly described in clause 9 of GSM 03.40. Specifications are based upon individual contributions. Any judgement concerning functionality, completeness and advantageddisadvantages of implementation is intentionally om

35、 This clause specifies a stack of communication protocols in terms of the OS1 Reference Model (see X.20) and therefore makes use of all seven layers for the purpose of relaying short messages and alerts between SC and MSC for the Short Message Service. The SMS application layer (layer 7) is mapped t

36、o the Presentation Layer via ACSE (see X.217 and X.227) and ROSE (see X.219 and X.229). Only the Kernel functional unit of the Presentation Layer is used. Only Kernel and Duplex functional units are used in the Session Layer (see X.215 and X.225). STD-ETSI TR 303 b35-ENGL 1999 = 3400855 O440368 5Lb

37、(GSM 03.47 version 7.0.0 Release 1998) 7 ETSI TR 1 O1 635 V7.0.0 (1999-08) 2.1 Service elements on the application layer An association (class 3) between SMRSEs is formed via ACSE and ROSE operations (class 2 and 5) are used to implement the Short Message Relay Layer described in clause 9 of GSM 03.

38、40. This results into a asynchronous symmetric situation where both (the application entity in) the SC and (the application entity in) the MSC can invoke a SMRSE operation at any time. The new SMRSE service element is first defined in this section, and then specified in ASN. 1 notation in section 2.

39、2. SMRSE definition This service element defines the following services: SMR-BIND This operation must be invoked by that party which established the application association; only after that may the remaining SMRSE services be used. This operation reports either success or failure (result or error).

40、SMR-MO-DATA This operation may be invoked by the application entity in the MSC; it is used to relay one SMS transfer layer PDU from the IWMSC to the SC. This operation reports either success or failure. SMR-MT-DATAThis operation may be invoked by the application entity in the SC; it is used to relay

41、 one SMS transfer layer PDU from the SC to the GMSC, to be further relayed to the MS addressed. This operation reports either success or failure, after the full relay attempt to the MS. This operation may be invoked by the application entity in the MSC. It is used as the GMSC-to-SC indication of the

42、 fact that an MS which was previously unattainable has recovered operation. This operation does not report any outcome. SMR-UNBIND Thi operation must be invoked by that party which invoked the SMR-BIND operation, as the last SMR-ALERT SM x SE operation before releasing the application association. T

43、his operation reports success only. Of the services defined above, SMR-MO-DATA and SMR-MT-DATA semantically mean the relay of short messages across the SC-MSC-connection; SMR-ALERT similarly implements the alerting operation. The SMR-BIND service is used to exchange identifications, passwords, etc.,

44、 and in order to negotiate the usage of the other services. The SMR- UNBIND service prepares for the release of the application association. 2.2 Detailed specification of the SMRSE services On the following pages, the new SMRSE service element is specified with the ASN. 1 notation, together with the

45、 entire SM-RL protocol. The Abstract Syntax Notation of the Short Message Relay Service Element SMRSE NOTE: The first two arcs of the object identifier are arbitrarily allocated, the name “etsi“ is adopted from GSM 12.20 but the value 040 is arbitrary, and the last three arcs are allocated in this m
