`
`Foreword
`
`This Global System for Mobile communications Technical Specification (GTS) has been produced by the
`Special Mobile Group (SMG) Technical Committee (TC) of the European Telecommunications Standards
`Institute (ETSI).
`
`This GTS defines the Short Message Service (SMS) support on mobile radio interface within the digital
`cellular telecommunications system (Phase 2/Phase 2+).
`
`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 ETS from which this Phase 2+
`GTS has evolved is Phase 2 GSM ETS 300 559 edition 3 (GSM 04.11 version 4.10.0).
`
`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 European
`Telecommunications 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 Mobile
`communications.
`
`The contents of this GTS are subject to continuing work within TC-SMG and may change following formal
`TC-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 5.x.y
`
`where:
`
`y
`
`x
`
`the third digit is incremented when editorial only changes have been incorporated in the
`specification;
`
`the second digit is incremented for all other types of changes, i.e. technical enhancements,
`corrections, updates, etc.
`
`The specification from which this GTS has been derived was originally based on CEPT documentation,
`hence the presentation of this GTS may not be entirely in accordance with the ETSl rules.
`
`Reference is made within this GTS to GSM-TSs (note).
`
`NOTE:
`
`TC—SMG has produced documents which give the technical specifications for the
`implementation of the digital cellular telecommunications system. Historically,
`these
`documents have been identified as GSM Technical Specifications (GSM-TSs). These
`TSs may have subsequently become l-ETSs (Phase 1), or ETSs/ETSI Technical
`Reports (ETRs) (Phase 2). TC-SMG has also produced ETSI GSM TSs which give the
`technical specifications for the implementation of Phase 2+ enhancements of the digital
`cellular telecommunications system. These version 5.x.x GSM Technical Specifications
`may be referred to as GTSs.

`
`Overview of Short Message Service (SMS) support
`
`The purpose of the Short Message Service is to provide the means to transfer messages between a GSM
`PLMN Mobile Station and a Short Message Entity via
`a Service Centre, as described in
`T8 GSM 03.40. The terms "MO" - Mobile Originating — and "MT" - Mobile Terminating — are used to
`indicate the direction in which the short message is sent.
`
`This Technical Specification describes the procedures necessary to support the Short Message Service
`between the MS and the MSC and vice versa, as described in TS GSM 03.40.
`
`The procedures are based on services provided by the Mobility Management sublayer as described in TS
`GSM 04.07/04.08.
`

`
`The CM-sublayer, in terms of the Short Message Service Support, provides services to the Short Message
`Relay Layer.
`
`On the MS—side the Short Message Relay Layer provides services to the Short Message Transfer Layer.
`The Short Message Relay Layer is the upper layer on the network side (MSC), and the SM-user
`information elements are mapped to TCAP/MAP.
`
`The peer protocol between two SMC entities is denoted SM-CP, and between two SMR entities, SM—RP.

`
`Use of channels
`
`The short message service will be supported by an SDCCH or SACCH, depending on the use of a TCH;
`
`—
`
`-
`
`-
`
`-
`
`When a TCH is not allocated, the short message service will use an SDCCH;
`
`If a TCH is allocated during a short message transaction on an SDCCH,
`transaction will stop and continue on the SACCH associated with the TCH;

`the short message

`If a TCH is allocated for the short message service.

`
`the short message service will use the
`
`When an entity using a TCH finishes its transaction, the RR-sublayer may choose to continue an
`ongoing short message transfer on the SACCH, or optionally transfer it to an SDCCH.
`
`Table 2.1IGSM 04.11 summarizes the use of channels for the short message service. Arrows indicate
`changes of channel.

`
`Layer 2 SAPI 3 handling
`
`General rule:
`
`The Radio Resource Management (RR ref. TS. GSM 04.08) in the Mobile Station and on the network side
`(i.e.
`in the BSC) shall establish the acknowledged mode of operation on SAPI 3 whenever needed,
`i.e.
`when a message requiring SAPl 3 transfer shall be transmitted.
`
`RR shall control the layer 2 also for SAPI 3, and keep knowledge of the mode.
`
`The network side may initiate release of the acknowledged mode for SAPI 3 either explicitly (by the use of
`0180- and UA—frames, ref., TS GSM 04.06) or indirectly by Channel release (ref. TS GSM 04.08).
`
`This means:
`
`-
`
`-
`
`-
`
`initiate establishment of SAPI 3 acknowledged mode in the case of
`the Mobile Station side will
`mobile originating short message transfer;
`
`initiate establishment of SAPI 3 acknowledged mode in the case of mobile
`the network side will
`terminating short message transfer;
`
`the network side may choose to keep the channel and the acknowledged mode of operation to
`facilitate transfer of several short messages for or from the same Mobile Station. The queuing and
`scheduling function for this should reside in the MSC.

`The layer service is described as a set of service primitives. These seNioe primitives are abstractions and
`attempt to capture only those details of the interaction between the entities that are aspects of the layer
`service itself. A service primitive neither specifies nor constrains the implementation of entities or the
`interface between them.
`
`The general syntax of a primitive and the initials of them are in line with the 04-series of GSM Technical
`Specifications.
`
`NOTE:
`
`In order to limit the number of primitives and state definitions to a reasonable amount, a
`description method has been chosen which does not claim to be totally in line with the
`formal description method of the layered ISO reference model (ISO 7498) for Open
`Systems lnterconnection.
`
`3.2
`
`Service provided by the CM-sublayer
`
`In order to support the Short Message Service, the CM—sublayer provides services to the Short Message
`Relay Layer.
`
`The CM-sublayer services are provided using layer specific functions and lower layer services offered to
`the CM-sublayer, controlled by short message service control entities called SMCs.
`
`An SMC entity in the MS communicates with an SMC entity in the MSC by means of a peer protocol, SM-
`CP (Short Message Service Control Protocol). The arrow diagrams in annex A give an overview of the
`messaging on the CM—sublayer during a short message transfer.
`
`A mobile station supporting the short message service shall have a minimum of two SMC entities. This
`enables the MS to receive MT messages during an M0 message transfer.
`
`To ensure that an MS having the minimum of two SMC entities is able to receive MT messages during an
`M0 message transfer. and to send MO messages during MT message transfer, parallel message transfer
`in the same direction is prohibited. This means that the SMC entities shall not simultaneously perform
`messaging in the same direction. The rules for concatenation of message transfers are described in
`section 5.4.
`
`The MSC shall have a minimum of two SMC entities available during an MT message transfer to a mobile
`station, one being reserved for M0 message transfer.
`In an M0 message transfer, the MSC shall have
`one SMC entity reserved for handling of an MT message.

`
`Definition of primitives on the MS side
`
`This section defines the service primitives used on the MS side. Table 3.1/GSM 04.11 gives an overview
`of the service primitives and main parameter linked to the primitives. All necessary control parameters to
`be used in the short message service are defined in section 7. All MNSMS service primitives defined in this
`section are passed to an SMC-entity.

`
`Service provided by SM-RL
`
`In order to support the Short Message Service, the Short Message Relay Layer provides services to the
`Short Message Transfer Layer.
`
`The Short Message Relay Layer services are provided using layer specific functions and lower layer
`services offered to the Short Message Relay Layer, controlled by short message control entities called
`SMRs.
`
`An SMR entity in the MS communicates with an SMR entity in the MSC by means of a peer protocol, SM-
`RP (Short Message Relay Protocol). The arrow diagrams in annex C give an overview of the messaging
`on the Short Message Relay Layer used for the short message service. The diagrams in annex C indicate
`a layer RL. This is not a layer, but the functional interface to the fixed network. The SM-RL is the upper
`layer in the MSC. Consequently the service primitives passed between
