3 This GTS is a TC-SMG approved GSM technical specification Version 5, which contains GSM Phase 2+enhancements/features to the Version 4 GSM technical specification. The European TelecommunicationsStandard from which this Phase 2+ GTS has evolved is Phase 2 GSM ETS 300 628 (GSM Version ).GTS are produced by TC-SMG to enable the GSM Phase 2+ specifications to become publicly available,prior to submission for the formal ETSI standards approval procedure to become EuropeanTelecommunications Standards (ETS). This ensures the earliest possible access to GSM Phase 2+specifications for all Manufacturers, Network operators and implementors of the Global System for contents of this GTS are subject to continuing work within TC-SMG and may change following formalTC-SMG approval. Should TC-SMG modify the contents of this GTS it will then be republished by ETSI with an identifying change of release date and an increase in Version number as follows: Version :ythe third digit is incremented when editorial only changes have been incorporated in thespecification;xthe second digit is incremented for all other types of changes, technical enhancements,corrections, updates, is made within this TS to GSM-TSs (note).

4 NOTE:TC-SMG has produced documents which give the technical specifications for theimplementation of the Digital cellular telecommunications system. Historically, thesedocuments have been identified as GSM Technical Specifications (GSM-TSs). TheseTSs may have subsequently become I-ETSs (Phase 1), or ETSs/ETSI TechnicalReports (ETRs) (Phase 2). TC-SMG has also produced ETSI GSM TSs which give thetechnical specifications for the implementation of Phase 2+ enhancements of thedigital cellular telecommunications system. These Version GSM TechnicalSpecifications may be referred to as 6 GSM Version : December 1995 Blank pagePage 7 GSM Version : December 19951 ScopeThis Global System for Mobile communications Technical Specification (GTS) defines the language-specific requirements for GSM. These are specific codepoints required by the Short Message Service(SMS) specifications which in turn are used not only for SMS (GSM , ) but also forUnstructured Data (GSM ) and may additionally be used for Man Machine Interface (MMI)(GSM ).

5 The specification for the Data Circuit terminating Equipment/Data Terminal Equipment (DCE/DTE)interface (GSM ) will also use the codes specified herein for the transfer of SMS data to an referencesThis GTS incorporates by dated and undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listedhereafter.

7 3 Abbreviations Definitions used in this specification are listed in GSM 8 GSM Version : December 19954 SMS Data Coding SchemeThe TP-Data-Coding-Scheme field, defined in GSM , indicates the data coding scheme of theTP-UD field, and may indicate a message class. The octet is used according to a coding group which isindicated in bits The octet is then coded as follows:Coding Group BitsUse of bits indicationUnspecified message handling at the indicate the alphabet as follows:0000 Default coding groups1100 Message Waiting Indication Group: Discard MessageBits are coded exactly the same as Group 1101, however with bits set to 1100 the mobilemay discard the contents of the message, and only present the indication to the Waiting Indication Group: Store MessageThis Group allows an indication to be provided to the user about the status of types of messagewaiting on systems connected to the GSM PLMN. The mobile may present this indication as anicon on the screen, or other MMI indication.

8 The mobile may take note of the Origination Addressfor messages in this group and group 1100. For each indication supported, the mobile may providestorage for the Origination Address which is to control the mobile indicatorText included in the user data is coded in the Default a message is received with bits set to 1101, the mobile shall store the text of the SMSmessage in addition to setting the 3 indicates Indication Sense:Bit 30 Set Indication Inactive1 Set Indication ActiveBit 2 is reserved, and set to 0 Bit 1 Bit 0 Indication Type:00 Voicemail Message Waiting01 Fax Message Waiting10 Electronic Mail Message Waiting11 Other Message Waiting** Mobile manufacturers may implement the Other Message Waiting indication as an additionalindication without specifying the meaning. The meaning of this indication is intended to bestandardised in the future, so Operators should not make use of this indication until the standardfor this indication is Coding Group1111 Data coding/message classBit 3 is reserved, set to 2 Message coding:0 Default alphabet18-bit dataBit 1 Bit 0 Message Class:00 Class 001 Class 1default meaning: 2 SIM-specific 3default meaning: TE specific (see GSM TS )Page 9 GSM Version : December 1995 Default alphabet indicates that the TP-UD is coded from the 7-bit alphabet given in subclause Whenthis alphabet is used, the characters of the message are packed in octets as shown in , and the message can consist of up to 160 characters.

9 The default alphabet shall be supportedby all MSs and SCs offering the data indicates that the TP-UD has user-defined coding, and the message can consist of up to a mobile terminated message is class 0 and the MS has the capability of displaying shortmessages, the MS shall display the message immediately and send an acknowledgement to the SC whenthe message has successfully reached the MS irrespective of whether there is memory available in theSIM or ME. The message shall not be automatically stored in the SIM or ME may make provision through MMI for the user to selectively prevent the message from beingdisplayed the ME is incapable of displaying short messages or if the immediate display of the message has beendisabled through MMI then the ME shall treat the short message as though there was no message class, it will ignore bits 0 and 1 in the TP-DCS and normal rules for memory capacity exceeded shall a mobile terminated message is Class 1, the MS shall send an acknowledgement to the SC whenthe message has successfully reached the MS and can be stored.

10 The MS shall normally store themessage in the ME by default, if that is possible, but otherwise the message may be stored elsewhere, in the SIM. The user may be able to override the default meaning and select their own a mobile terminated message is Class 2 (SIM-specific), a phase 2 (or later) MS shall ensure thatthe message has been transferred to the SMS data field in the SIM before sending an acknowledgementto the SC. The MS shall return a "protocol error, unspecified" error message (see GSM TS ) if theshort message cannot be stored in the SIM and there is other short message storage available at the all the short message storage at the MS is already in use, the MS shall return "memory capacityexceeded".When a mobile terminated message is Class 3, the MS shall send an acknowledgement to the SC whenthe message has successfully reached the MS and can be stored, irrespectively of whether the MSsupports an SMS interface to a TE, and without waiting for the message to be transferred to the TE.
