Page 7ETS 300 392-13: May 19971ScopeThis European Telecommunication Standard (ETS) defines the Specification and Description Language(SDL) model of the TETRA Voice plus Data (V+D) Air Interface (AI).2Normative referencesThis ETS 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. For dated references, subsequent amendments to or revisions of any of these publicationsapply to this ETS only when incorporated in it by amendment or revision. For undated references the latestedition of the publication referred to applies.[1]ETS 300 392-2: "Radio Equipment and Systems (RES); Trans-EuropeanTrunked RAdio (TETRA); Voice plus Data (V+D); Part 2: Air Interface".[2]ITU-T Recommendation Z.100 (1993): "Specification and Description Language(SDL)".[3]ISO/IEC 8878: "Use of X.25 to provide the OSI connection mode networkservice".3Definitions and abbreviations3.1DefinitionsFor the purposes of this ETS, the following definitions apply:acknowledged data transfer: A service provided by the layer below which gives an acknowledgementback over the air interface from the lower layer peer entity. This service is used by the layer 3 entities toacquire a secure transmission including re-transmissions.Advanced Link (AL): An AL is a bi-directional connection between one Mobile Station (MS) and a BaseStation (BS) with provision of acknowledged and unacknowledged services including windowing,segmentation, extended error protection and choice among several throughputs. The data transfer via theAL requires a set-up phase.announced cell re-selection: Cell re-selection where MS Mobile Link Entity (MLE) informs the Switchingand Management Infrastructure (SwMI) both in the serving cell and in the new cell that cell change isperformed. There can be three types of announced cell re-selection:-type 1: The MS-MLE knows the new cell and the traffic channel allocations on the cell beforedeciding to leave its serving cell;-type 2: The MS-MLE knows the new cell before changing to it, but does not know the channelallocation on the new cell in advance;-type 3: The MS-MLE need not to know the new cell before changing to it. The serving cell is onlyinformed by the MS-MLE that it wants to change cell.TETRA V+D may support all three types of announced cell re-selection.attached: An MS is said to be attached to a cell when the MS is camped and registered on the cell. TheMS may be in idle mode (i.e. not actively processing a transaction) or in traffic mode (i.e. activelyprocessing a transaction in reception and/or in transmission). It is the Mobility Management (MM) whichdecides when an MS is said to be attached.Basic Link (BL): A bi-directional connectionless path between one or several MSs and a BS, with aprovision of both unacknowledged and acknowledged services on a single message basis.SIST ETS 300 392-13:1999



Page 8ETS 300 392-13: May 1997call transaction: All of the functions associated with a complete unidirectional transmission of informationduring a call. A call can be made up of one or more call transactions. In a semi-duplex call these calltransactions are sequential.camped: An MS is said to be camped on a cell when the MS is synchronized on the cell BS and hasdecoded the Broadcast Network CHannel (BNCH) of the cell. The synchronization procedure is performedby the Medium Access Control (MAC) entity and the interpretation of the Network information from theBNCH is performed by a procedure in the MLE. It is the MLE which decides when an MS is said to becamped on a cell.cell re-selection: The act of changing the serving cell from an old cell to a new cell. The cell re-selectionis performed by procedures located in MLE and in the MAC. When the re-selection is made and possibleregistration is performed, the MS is said to be attached to the cell.cell-id: Characterized as the channel number of the main carrier on the cell.confirmed service: A service provided by the layer below which ensures that a message is responded toby the peer entity before new messages are allowed. The service may be used for synchronization of peerentities or for provision of sequential behaviour.current serving BS: The BS on one of whose channels the MS is currently operating.direct set-up signalling: A signalling procedure where immediate communication can take placebetween the calling and the called users without the alerting process and without an explicit response fromthe called user that he has answered.initial cell selection: The act of choosing a first serving cell to register in. The initial cell selection isperformed by procedures located in MLE and in the MAC. When the cell selection is made and possibleregistration is performed, the MS is said to be attached to the cell.migration: The act of changing to a new location area in a network (either with different Mobile NetworkCode (MNC) and/or Mobile Country Code (MCC)) where the user does not have subscription, anIndividual TETRA Subscriber Identity (ITSI) for that network.monitoring: The act of measuring the power of neighbour cells and calculate the path loss parameter C2based upon information on neighbour cells broadcasted by the serving cell.on/off hook signalling: A signalling procedure which includes an alerting process to the called user. Thecalling user waits for an explicit response from the called user that he has answered before the call can beset-up.received segment sequence number: The number of the currently received segment.roaming: The act of changing location area within a network of same MNC/MCC, and for which the userhas a valid registration (ITSI).scanning: The act of measuring the power of neighbour cells and calculate the path loss parameter C1based upon the information on the neighbour cells broadcasted by the neighbour cells themselves.segment: A Logical Link Control (LLC) segment is the AL unit of transmission and re-transmission. Asegment is the numbered piece of a TL-SDU fitting into one MAC layer Protocol Data Unit (PDU) (MACblock). A segment is a synonym to a PDU.Service Data Unit (SDU) number: A number on the LLC entity to keep TL-SDUs in order.serving cell: The cell that is currently providing services to the MS.subscriber class: A subscriber class has no other defined usage than offering a population subdivision.The operator defines the values and meaning of each class.surveillance: The process of monitoring the quality of the radio link to the serving cell.SIST ETS 300 392-13:1999



Page 9ETS 300 392-13: May 1997timebase: A device which determines the timing state of signals transmitted by a BS or MS.timeslot number: The timing of timeslots within a Time Division Multiple Access (TDMA) frame.TLC-SAP: The management Service Access Point (SAP) is a way of modelling layer-to-layercommunication for management and control purpose.un-acknowledged data transfer: A service which does not give any acknowledgement back to theservice user.unannounced cell re-selection: Cell re-selection where the MS-MLE does not inform the serving cellthat it intend to change to a new cell. Only the new cell is informed about the MS-MLE.unconfirmed service: A service which does not ensure response from peer entities before allowing newmessages. This implies that messages to be transported may arrive in different order at the peer entity.undeclared cell re-selection: Cell re-selection where the MS-MLE does not inform the serving cell northe new cell that cell change is performed.validation model: A model for the protocol specified with a formal description technique in this case,SDL.3.2AbbreviationsFor the purposes of this ETS, the following abbreviations apply:AIAir InterfaceALAdvanced LinkBLBasic LinkBNCHBroadcast Network CHannelBSBase StationCCCall ControlCMCECircuit Mode Control EntityCONPConnection Oriented Network ProtocolFCSFrame Check SequenceITSIIndividual TETRA Subscriber IdentityLLCLogical Link ControlLSLine StationMACMedium Access ControlMCCMobile Country CodeMLEMobile Link EntityMMMobility ManagementMNCMobile Network CodeMSMobile StationPCProtocol ControlPDUProtocol Data UnitPSPostScriptQoSQuality of ServiceSAPService Access PointSCLNPSpecific ConnectionLess Network ProtocolSDLSpecification and Description LanguageSDUService Data UnitSPService PrimitiveSSSupplementary ServiceSwMISwitching and Management InfrastructureTDMATime Division Multiple AccessTETRATerrestrial Trunked RAdioTL-SDUSDU from the service user (i.e. MLE)TLAA layer 2 service access point (TLA-SAP)TLBA layer 2 service access point (TLB-SAP)TLCA layer 2 service access point (TLC-SAP)TM-SDUSDU from the layer above MAC (i.e. LLC)V+DVoice plus DataSIST ETS 300 392-13:1999
