Page 9ETS 300 764: May 19971ScopeThis European Telecommunication Standard (ETS) is a part of the Digital Enhanced CordlessTelecommunications/Global System for Mobile communications (DECT/GSM) Interworking Profile (IWP)and specifies the Portable Part (PP) and Fixed Part (FP) interworking requirements/mappings necessaryto ensure that the GSM short message services point-to-point and cell broadcast can be provided overDECT, as specified in ETS 300 466 [12]. To enable DECT terminals to interwork with DECT systemswhich are connected to the GSM infrastructure, from the DECT side this ETS is based onETS 300 757 [27].NOTE:For information, the DECT Data service profile is based upon the GAP,ETS 300 444 [11] and on the DECT common interface specification, ETS 300 175,Parts 1 to 8 [1] to [8].Interworking functions/mappings are specified for Mobile Switching Centre (MSC) attachment for theDECT FP as the FP is using the A-interface towards the GSM MSC in the respect that the FP emulates aGSM Base Station Controller (BSC) with regards to the GSM messages which are relevant to this ETS.The complete interface used between the DECT FP and the GSM MSC is specified in ETS 300 499 [13].Attachment via other interfaces to GSM networks is outside the scope of this ETS.The DECT access protocols and FP and PP interworking/mappings necessary for the support of basicvoice telephony service are specified in ETS 300 370 [10].SIST ETS 300 764:2001

The reverse process is detach, which reports the PP as inoperative.NOTE 1:An operative PP is assumed to be ready to receive calls.authentication: The process whereby a DECT subscriber is positively verified to be a legitimate user of aparticular FP.NOTE 2:Authentication is generally performed at call set-up, but may also be done at any othertime (e.g. during a call).bearer service: A type of telecommunication service that provides a defined capability for thetransmission of signals between user-network interfaces.NOTE 3:The DECT user-network interface corresponds to the top of the network layer (layer 3).C-plane: The control plane of the DECT protocol stacks, which contains all of the internal DECT protocolcontrol, but may also include some external user information.NOTE 4:The C-plane stack always contains protocol entities up to and including the networklayer.call: All of the Network (NWK) layer processes involved in one network layer peer-to-peer association.NOTE 5:Call may sometimes be used to refer to processes of all layers, since lower layerprocesses are implicitly required.DECT Network (DNW): A network that uses the DECT air interface to interconnect a local network to oneor more portable applications. The logical boundaries of the DECT network are defined to be at the top ofthe DECT network layer.NOTE 6:A DNW is a logical grouping that contains one or more fixed radio termination plustheir associated portable radio termination. The boundaries of the DECT network arenot physical boundaries.Fixed Part (FP) (DECT FP): A physical grouping that contains all of the elements in the DECT networkbetween the local network and the DECT air interface.NOTE 7:A DECT FP contains the logical elements of at least one fixed radio termination, plusadditional implementation specific elements.FP GSM PLMN Attachment (DECT FP Attached To A GSM MSC): A definition of a functionalenvironment where a DECT system (FP) is attached to an GSM MSC. The MSC in this case refers to afunctional entity providing the required MM and Call Control (CC) functionality defined in this ETS in orderto communicate with the FP.Fixed radio Termination (FT): A logical group of functions that contains all of the DECT processes andprocedures on the fixed side of the DECT air interface.NOTE 8:A FT only includes elements that are defined in the DECT CI standard. This includesradio transmission elements together with a selection of layer 2 and layer 3 elements.Generic Access Profile (GAP): A defined part of the DECT Common Interface standard (DECT CI) thatensures inter-operability between FPs and PPs for public business and residential access services.SIST ETS 300 764:2001

Page 14ETS 300 764: May 1997geographically unique identity: This term relates to FP identities, Primary Access Rights Identities(PARIs) and Radio Fixed Part Identities (RFPIs). It indicates that two systems with the same PARI, orrespectively two Radio Fixed Parts (RFPs) with the same RFPI, can not be reached or listened to at thesame geographical position.Global Network (GNW): A telecommunication network capable of offering a long distancetelecommunication service.NOTE 9:The term does not include legal or regulatory aspects, nor does it indicate if thenetwork is a public or a private network.globally unique identity: The identity is unique within DECT (without geographical or other restrictions).handover: The process of switching a call in progress from one physical channel to another physicalchannel. These processes can be internal (see internal handover) or external (see external handover).NOTE 10:There are two physical forms of handover, intra-cell handover and inter-cell handover.Intra-cell handover is always internal. Inter-cell handover can be internal or external.incoming call: A call received at a PP.inter-cell handover: The switching of a call in progress from one cell to another cell.internal handover: Handover processes that are completely internal to one Fixed radio Termination (FT).Internal handover re-connects the call at the lower layers, while maintaining the call at the NWK layer.NOTE 11:The lower layer reconnection can either be at the Data Link Control (DLC) layer(connection handover) or at the MAC layer (bearer handover).inter-operability: The capability of FPs and PPs, that enable a PP to obtain access to teleservices inmore than one location area and/or from more than one operator (more than one service provider).inter-operator roaming: Roaming between FP coverage areas of different operators (different serviceproviders).Interworking Unit (IWU): A unit that is used to interconnect sub-networks.NOTE 12:The IWU will contain the interworking functions necessary to support the required sub-network interworking.intra-cell handover: The switching of a call in progress from one physical channel of one cell to anotherphysical channel of the same cell.intra-operator roaming: Roaming between different FP coverage areas of the same operator (sameservice provider).Local Network (LNW): A telecommunication network capable of offering local telecommunicationservices.NOTE 13:The term does not include legal or regulatory aspects, nor does it indicate if thenetwork is a public network or a private network.locally unique identity: The identity is unique within one FP or location area, depending on application.location area: The domain in which a PP may receive (and/or make) calls as a result of a single locationregistration.location registration: The process whereby the position of a DECT portable termination is determined tothe level of one location area, and this position is updated in one or more databases.NOTE 14:These databases are not included within the DECT FT.SIST ETS 300 764:2001

Page 15ETS 300 764: May 1997Medium Access Control (MAC) connection: An association between one source MAC Multi-BearerControl (MBC) entity and one destination MAC MBC entity. This provides a set of related MAC services (aset of logical channels), and it can involve one or more underlying MAC bearers.Multimedia Messaging Service (MMS): The MMS is a generic set of commands, information elementsproviding a functionality for file/messaging service. MMS can be regarded as a DECT internal teleservicethat can be interworked to the similar services in external networks.Multimedia Messaging Service Protocol (MMSP): A protocol that is used for the provision of MMSservices and functionality. It is a stateless protocol which defines a set of messages, framing rules andinformation elements each containing optional and mandatory information fields.outgoing call: A call originating from a PP.Portable Application (PA): A logical grouping that contains all the elements that lie beyond the DECTnetwork boundary on the portable side.NOTE 15:The functions contained in the portable application may be physically distributed, butany such distribution is invisible to the DECT network.Portable Part (PP) (DECT PP): A physical grouping that contains all elements between the user and theDECT air interface. PP is a generic term that may describe one or several physical pieces.NOTE 16:A DECT PP is logically divided into one portable termination plus one or more portableapplications.Portable radio Termination (PT): A logical group of functions that contains all of the DECT processesand procedures on the portable side of the DECT air interface.NOTE 17:A PT only includes elements that are defined in the DECT Common Interface (CI)standard. This includes radio transmission elements (layer 1) together with a selectionof layer 2 and layer 3 elements.Radio Fixed Part (RFP): One physical sub-group of a FP that contains all the radio end points (one ormore) that are connected to a single system of antennas.registration: An ambiguous term, that should always be qualified. See either location registration orsubscription registration.roaming: The movement of a PP from one FP coverage area to another FP coverage area, where thecapabilities of the FPs enable the PP to make or receive calls in both areas.NOTE 18:Roaming requires the relevant FPs and PP to be inter-operable.service type E: A DECT short message transfer or paging service which may be unacknowledged oracknowledged, optimized for small Service Data Units (SDUs), low PP complexity and ultra-low powerconsumption.subscription registration: The infrequent process whereby a subscriber obtains access rights to one ormore FPs.NOTE 19:Subscription registration is usually required before a user can make or receive calls.SIST ETS 300 764:2001

Page 18ETS 300 764: May 19974GeneralThis ETS specifies how the GSM point to point Short Message Services (SMSs) (GSM teleservices 21and 22) and cell broadcast service (GSM teleservice 23) are provided over the DECT air interface.One of the main objectives is to describe how the SMSs are mapped over the DECT air interface in aformal way, so that inter-operability of different manufacturer's equipment can be achieved. This is doneby describing the interworking unit procedures and mappings loosely following CCITT RecommendationsQ.601 to Q.699 and by describing an air interface profile following ISO 9646-6 [34]. ISO 9646-6 [34]enables the subsequent generation of tests cases, if required.This ETS is made up of 3 main clauses:Clause 5: Interworking requirements - includes reference configurations and the protocol architecturemodels. Also describes the main service requirements. The context of the interworking profile is alsorequired.Clauses 6: Interworking Unit (IWU) mappings for SMSs shows the C plane mappings for the FP GSMPublic Land Mobile Network (PLMN) attachment. Two IWUs are considered; the FP IWU and the PPIWU, although the FP IWU is expected to be the largest. The signalling mappings are described in termsof IWU procedures with informative data flow diagrams. Detailed descriptions follow using tables of whatis mapped, what is ignored, and what is transferred transparently. These clauses also include other profilespecific information.Clause 7: Connection types - this clause identifies the main DECT connection types (C plane) at the airinterface supporting optimized groups of services, from the IWU mappings for differentconfigurations/models.5Interworking requirements5.1GeneralThis ETS defines the mandatory requirements for the FP in terms of interworking functions between theair interface and the external network as well as minimum requirements at the DECT air interface. It alsodefines the mandatory requirements for the PP in terms of interworking functions between the air interfaceand the PA as well as the minimum requirements for the PP at the DECT air interface.If not stated otherwise the ETS 300 370 [10] requirements are the basis for this ETS.The interworking mappings shall be based on the Phase 2 GSM Standards.The basis for interworking shall be the protocols defined in ETS 300 557 [18], in ETS 300 590 [22] inETS 300 536 [15], in ETS 300 537 [16], ETS 300 559 [19], ETS 300 560 [20] and in ETS 300 628 [24].The minimum requirement defined in ETS 300 757 [27] shall be fulfilled in the PT and FT.NOTE:This means that the support of Low Rate Messaging Service Point-To-Point(LRMS PTP) service is required.The procedures which are used depend on which Access Rights Identifier (ARI) type is chosen by the PP;either according to the minimum requirements of ETS 300 757 [27] or the procedures as described in thisETS, i.e. the PPs, which are based on this ETS shall always be capable of interworking with FP which fulfilthe minimum requirements of LRMS PTP service. The FPs, which fulfil the requirements of this ETS, andwhich support also non-GSM ARIs (classes A, B or C) shall also support the minimum requirements of theData service profile E, class 2.This ETS defines interworking environments for the FP and the PP in the case when DECT FPs arefunctionally attached to the GSM MSC i.e. broadcast attribute a39 "SIM services available" set to '1'B in allenvironments (public, business and residential). The PP shall be in alignment with the requirements asdefined in this ETS.SIST ETS 300 764:2001

Page 19ETS 300 764: May 19975.2Reference configurationsReference configurations describe the functional groupings of DECT and GSM and their relationships viareference points. In general, reference points may or may not correspond to a physical interface. Thefunctional groupings and reference points for GSM access are described in ETS 300 551 [17]. The GSMnetwork entities and physical interfaces are described in ETS 300 522 [14]. The functional (logical)groupings and reference points for DECT are described below.5.2.1FP functional attachment to the GSM PLMNReference point "a" in figure 1 is the interface which supports the functional structure of the GSMA-interface at the network layer reflecting the associated ISDN User Part (ISUP)/Telephony User Part(TUP) and GSM Mobile Application Part (MAP) functions.PPFPReference pointaMSCOther GSMnetworkelementsGSM SMSservicecentreFigure 1: Attachment to the GSM PLMN in the case of point to point SMSReference point "b" in figure 2 is the interface which supports the functional structure of the respectiveinterface defined in subclause 9.1 of ETS 300 537 [16] as a message transfer link 2 to support the SMSscell broadcast protocols at this reference point. The management function as described inETS 300 537 [16] clause 6 is outside of the FP interworking function. However, this specification does notlimit the implementation of the GSM BSC cell broadcast related application features and functions whichare outside the FP IWU and between the GSM Cell Broadcast Centre (CBC) and DECT FP IWU. Thisspecification defines only the DECT air interface functions for the provision of the Cell Broadcast Service(CBS) information over the DECT air interface.PPFPReference pointbGSMSMSCBCFigure 2: Attachment to the GSM PLMN in the case of Cell broadcast SMSIn this ETS, GSM or DECT procedures are considered only where mapping is required, i.e.:-GSM CM sublayer is covered in this ETS as far as short message point-to-point services areconcerned;-the sublayers required by SMS Cell Broadcast (SMSCB) are concerned;-mapping aspects for ciphering, paging and handover are covered in ETS 300 370 [10]. Furtherdetails of these procedures are described in ETS 300 499 [13]. ETS 300 499 [13] also providesdescriptions for handling of other A-interface functionality (of ETS 300 590 [22]) which are out ofscope of this ETS, but which may occur during the procedures described in this ETS (e.g. channelassignment).5.3Service requirementsGeneral description of service requirements, functional capabilities and information flows are specified inETS 300 466 [12]. The detailed information regarding the supported service and service types is asfollows. Table 1 defines the GSM SMS as described in ETS 300 501 [19] supported by this ETS.SIST ETS 300 764:2001

The MAC layer shall use the Cs channel for the service provision.NOTE 1:The requirements of the CC and MM for this ETS are listed in ETS 300 757 [27] withconditions to "LRMS PTP supported" and "GAP call control supported" and inETS 300 370 [10] for those requirements set in this ETS.NOTE 2:The additional requirements over the basic GAP CC entity is the support of the MMSP(Multimedia Messaging Service Protocol).The data service profile E, class 2 (see ETS 300 757 [27]) MMSP protocol layer in conjunction with theDECT CC entity shall be used as a transportation mechanism for the GSM SMS SM-RP layer messages.If external handover is supported then the MMSP acknowledgements shall be used for mapping of theSMS Control Layer Protocol (SM-CP) acknowledgements. Thus the PP has GSM SM-TP and SM-RPprotocol layers.If both SM MO and SM MT are supported, they shall be supported simultaneously by independent CCinstances. The SM MO and SM MT shall be supported simultaneously and independently from possibleother CC instances. This implies that all simultaneously ongoing CC instances (e.g. voice, SM MO, andSM MT) use different transaction identifiers.If the SMS cell broadcast (GSM teleservice 23) interworking is supported the requirements of the CLMSFIXED service as specified in ETS 300 175-5 [5] shall apply. This means the usage of ConnectionlessMessage Service (CLMS) entity on the DECT network layer.The MM entity in the FT and PT shall fulfil the r
