Page 5ETS 300 792: June 1997ForewordThis European Telecommunication Standard (ETS) has been produced by the Digital Enhanced CordlessTelecommunications (DECT) Project of the European Telecommunications Standards Institute (ETSI).Transposition datesDate of adoption:6 June 1997Date of latest announcement of this ETS (doa):30 September 1997Date of latest publication of new National Standardor endorsement of this ETS (dop/e):31 March 1998Date of withdrawal of any conflicting National Standard (dow):31 March 1998IntroductionThis ETS is a part of a set of standards for the DECT/GSM Interworking Profile (IWP) concept thatincludes:-general description of service requirements, functional capabilities and information flows,(ETS 300 466 [13]);-access and mapping (protocol/procedure description for 3,1 kHz speech service),(ETS 300 370 [10]);-GSM-MSC/DECT-FP fixed interconnection (ETS 300 499 [14]);-GSM Phase 2 supplementary services implementation (ETS 300 703 [23]);-short message services, point to point and cell broadcast (ETS 300 764 [26]);-implementation of bearer services (ETS 300 756 [25]);-implementation of facsimile group 3 (this ETS).This ETS is based on Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI)specification ETS 300 175, parts 1 to 8 [1] to [8] to enable DECT terminals to interwork in the public andprivate environment with DECT systems which are connected to a Global System for Mobilecommunications (GSM) core infrastructure.In addition, this ETS is based on the DECT Generic Access Profile (GAP), ETS 300 444 [12] to enable thesame DECT/GSM terminal to interwork with a DECT Fixed Part (FP) complying to the GAP requirements,irrespective of whether this FP provides residential, business or public access services. Generalattachment requirements and speech attachment requirements are based on TBR 6 [28] and TBR 10 [29].Further details on the DECT system may be found in ETR 015 [30], ETR 043 [31], ETR 056 [32], and inETS 300 176 [9].SIST ETS 300 792:2001

Page 7ETS 300 792: June 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) interworking requirements and Fixed Part (FP) interworkingrequirements/mappings necessary to ensure that the GSM facsimile group 3 service can be provided overDECT, as specified in ETS 300 466 [13]. To enable DECT terminals to interwork with DECT systemswhich are connected to the GSM infrastructure, from the DECT side this ETS is based onETS 300 755 [24].NOTE:The DECT data service profile is based upon the Generic Access Profile (GAP)ETS 300 444 [12] 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 Fixed Part (FP) and the GSM Mobile Switching Centre(MSC) is specified in ETS 300 499 [14]. Attachment via other interfaces to GSM-networks is outside thescope 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]. Support of bearer services is specified inETS 300 756 [25].2Normative referencesThis ETS incorporates, by dated or undated reference, provisions from other publications.

Page 10ETS 300 792: June 19973Definitions, abbreviations and symbols3.1DefinitionsGSM-specific definitions may be found in ETR 100 [33]. In addition, for the purposes of this ETS, thefollowing definitions apply:attach: The process whereby a PP within the coverage area of a FP to which it has access rights, notifiesthis FP that it is operative. 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 DECT Network (DNW) is a logical grouping that contains one or more fixed radiotermination plus their associated portable radio termination. The boundaries of theDECT network are not physical boundaries.Fixed Part (DECT Fixed Part) (FP): A physical grouping that contains all of the elements in the DECTnetwork between 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.fixed part GSM PLMN attachment (DECT fixed part attached to a GSM MSC): A definition of afunctional environment where a DECT system (FP) is attached to an GSM MSC. The MSC in this caserefers to a functional entity providing the required MM and CC functionality defined in this ETS in order tocommunicate with the FP.SIST ETS 300 792:2001

Page 11ETS 300 792: June 1997Fixed 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 fixed radio termination only includes elements that are defined in the DECT CIstandard. This includes radio transmission elements together with a selection of layer2 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.geographically 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 requiredsub-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.SIST ETS 300 792:2001

Page 12ETS 300 792: June 1997locally 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.Medium 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 elementsand functionality for file/messaging service. MMS can be regarded as a DECT internal teleservice that canbe 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 that 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 (DECT Portable Part) (PP): A physical grouping that contains all elements between theuser and the DECT 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 CI standard. This includesradio transmission elements (layer 1) together with a selection of layer 2 and layer 3elements.Radio Fixed Part (RFP): One physical sub-group of an 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 F: An application profile specifically supporting teleservices such as fax, building upon theservices offered by the type A/B and C profiles, optimized for terminal simplicity, spectrum efficiency andnetwork flexibility.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 300 792:2001

Introduction

This ETS is a part of a set of standards for the DECT/GSM Interworking Profile (IWP) concept that

includes:

- general description of service requirements, functional capabilities and information flows,

(ETS 300 466 [13]);

- access and mapping (protocol/procedure description for 3,1 kHz speech service),

(ETS 300 370 [10]);
- GSM-MSC/DECT-FP fixed interconnection (ETS 300 499 [14]);
- GSM Phase 2 supplementary services implementation (ETS 300 703 [23]);
- short message services, point to point and cell broadcast (ETS 300 764 [26]);
- implementation of bearer services (ETS 300 756 [25]);
- implementation of facsimile group 3 (this ETS).

This ETS is based on Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI)

specification ETS 300 175, parts 1 to 8 [1] to [8] to enable DECT terminals to interwork in the public and

private environment with DECT systems which are connected to a Global System for Mobile

communications (GSM) core infrastructure.

In addition, this ETS is based on the DECT Generic Access Profile (GAP), ETS 300 444 [12] to enable the

same DECT/GSM terminal to interwork with a DECT Fixed Part (FP) complying to the GAP requirements,

irrespective of whether this FP provides residential, business or public access services. General

attachment requirements and speech attachment requirements are based on TBR 6 [28] and TBR 10 [29].

Further details on the DECT system may be found in ETR 015 [30], ETR 043 [31], ETR 056 [32], and in

ETS 300 176 [9].

1 Scope

This European Telecommunication Standard (ETS) is a part of the Digital Enhanced Cordless

Telecommunications / Global System for Mobile communications (DECT/GSM) Interworking Profile (IWP)

and specifies the Portable Part (PP) interworking requirements and Fixed Part (FP) interworking

requirements/mappings necessary to ensure that the GSM facsimile group 3 service can be provided over

DECT, as specified in ETS 300 466 [13]. To enable DECT terminals to interwork with DECT systems

which are connected to the GSM infrastructure, from the DECT side this ETS is based on

ETS 300 755 [24].

NOTE: The DECT data service profile is based upon the Generic Access Profile (GAP)

ETS 300 444 [12] 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 the

DECT FP as the FP is using the A-interface towards the GSM MSC in the respect that the FP emulates a

GSM Base Station Controller (BSC) with regards to the GSM messages which are relevant to this ETS.

The complete interface used between the DECT Fixed Part (FP) and the GSM Mobile Switching Centre

(MSC) is specified in ETS 300 499 [14]. 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 basic

voice telephony service are specified in ETS 300 370 [10]. Support of bearer services is specified in

ETS 300 756 [25].

3 Definitions, abbreviations and symbols
3.1 Definitions

GSM-specific definitions may be found in ETR 100 [33]. In addition, for the purposes of this ETS, the

following definitions apply:

attach: The process whereby a PP within the coverage area of a FP to which it has access rights, notifies

this FP that it is operative. 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 a

particular FP.

NOTE 2: Authentication is generally performed at call set-up, but may also be done at any other

time (e.g. during a call).

bearer service: A type of telecommunication service that provides a defined capability for the

transmission 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 protocol

control, but may also include some external user information.

NOTE 4: The C-Plane stack always contains protocol entities up to and including the network

layer.

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 layer

processes are implicitly required.

DECT Network (DNW): A network that uses the DECT air interface to interconnect a local network to one

or more portable applications. The logical boundaries of the DECT network are defined to be at the top of

the DECT network layer.

NOTE 6: A DECT Network (DNW) is a logical grouping that contains one or more fixed radio

termination plus their associated portable radio termination. The boundaries of the

DECT network are not physical boundaries.

Fixed Part (DECT Fixed Part) (FP): A physical grouping that contains all of the elements in the DECT

network between the local network and the DECT air interface.

NOTE 7: A DECT FP contains the logical elements of at least one fixed radio termination, plus

additional implementation specific elements.

fixed part GSM PLMN attachment (DECT fixed part attached to a GSM MSC): A definition of a

functional environment where a DECT system (FP) is attached to an GSM MSC. The MSC in this case

refers to a functional entity providing the required MM and CC functionality defined in this ETS in order to

communicate with the FP.
---------------------- Page: 12 ----------------------
SIST ETS 300 792:2001
Page 11
ETS 300 792: June 1997

Fixed radio Termination (FT): A logical group of functions that contains all of the DECT processes and

procedures on the fixed side of the DECT air interface.

NOTE 8: A fixed radio termination only includes elements that are defined in the DECT CI

standard. This includes radio 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) that

ensures inter-operability between FPs and PPs for public business and residential access services.

geographically 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, or

respectively two Radio Fixed Parts (RFPs) with the same RFPI, can not be reached or listened to at the

same geographical position.

Global Network (GNW): A telecommunication network capable of offering a long distance

telecommunication service.

NOTE 9: The term does not include legal or regulatory aspects, nor does it indicate if the

network 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 physical

channel. 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 in

more 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 service

providers).
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 another

physical channel of the same cell.

intra-operator roaming: Roaming between different FP coverage areas of the same operator (same

service provider).

Local Network (LNW): A telecommunication network capable of offering local telecommunication

services.

NOTE 13: The term does not include legal or regulatory aspects, nor does it indicate if the

network is a public network or a private network.
---------------------- Page: 13 ----------------------
SIST ETS 300 792:2001
Page 12
ETS 300 792: June 1997

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 location

registration.

location registration: The process whereby the position of a DECT portable termination is determined to

the 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.

Medium Access Control (MAC) connection: An association between one source MAC Multi-Bearer

Control (MBC) entity and one destination MAC MBC entity. This provides a set of related MAC services (a

set 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 elements

and functionality for file/messaging service. MMS can be regarded as a DECT internal teleservice that can

be interworked to the similar services in external networks.

Multimedia Messaging Service Protocol (MMSP): A protocol that is used for the provision of MMS

services and functionality that is a stateless protocol which defines a set of messages, framing rules and

information 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 DECT

network boundary on the portable side.

NOTE 15: The functions contained in the portable application may be physically distributed, but

any such distribution is invisible to the DECT network.
