11、 GSM 03.47 version 4.3.0 1.1 Scope No mandatory 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. This report specifies three approaches to the specification of pro

12、tocol stacks of communication protocols for the purpose of relaying short messages and alerts between Short Message Service Centres and Gateway/lnterworking MSCs (GMSC) for the Short Message Service (SMS). One approach is based upon use of the complete OS1 reference model (see X.200), another approa

13、ch is based upon the use of only 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.1 encoding rules (see X.208 and X.2091. These alternative protocol stacks are examples for the imple

14、mentation of the Short Message Relay Layer (SM- RL). The requirements placed upon the Short Message Relay Layer are briefly described in Section 9 of GSM 03.40. Specifications are based upon individual contributions. Any judgement concerning functionality, completeness and advantages/disadvantages o

15、f implementation is intentionally omitted. 1.2 References This ETR incorporates by dated and undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent a

27、otocols in terms of the OS1 Reference Model (see X.200) 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 to the Presentation Layer via ACSE (see X.217 and

28、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). ETSI GSM+03.47 74 3400855 0004312 912 Page 9 GSM 03.47 version 4.3.0 2.1 Service elements on the appl

29、ication 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 Section 9 of GSM 03.40. This results into a asynchronous symmetric situation where both (the application entity in) the SC and

30、 (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.l notation in section 2.2. SMRSE definition This service element defines the following services: SMR-BIND This operation must be in

31、voked 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). SMR-MO-DATA This operation may be invoked by the application entity in the MSC; it is used to relay one SMS

32、 transfer layer PDU from the IWMSC to the SC. This operation reports either success or failure. SM R-MT-DATA SMR-ALERT This operation may be invoked by the application entity in the SC; it is used to relay one SMS transfer layer PDU from the SC to the GMSC, to be further relayed to the MS addressed.

33、 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 fact that an MS which was previously unattainable has recovered operation. This operation does

34、 not report any outcome. SMR-UNBIND This operation must be invoked by that party which invoked the SMR-BIND operation, as the last SMRSE operation before releasing the application association. This operation reports success only. Of the services defined above, SMR-MO-DATA and SMR-MT-DATA semanticall

35、y 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., and in order to negotiate the usage of the other services. The SMR-UNBIND service prepares for the releas

36、e of the application association.
