1 Scope
General

This European Telecommunication Standard (ETS) defines the general requirements needed for the

provisioning of Global System for Mobile communications (GSM) basic services via the Digital Enhanced

Cordless Telecommunications (DECT) air interface for the case that the DECT network elements are

interconnected with the GSM Public Land Mobile Networks (PLMNs) via Integrated Services Digital

Network (ISDN) interfaces.

To enable DECT terminals to interwork with DECT systems which are connected to the GSM

infrastructure via ISDN interfaces, this ETS specifies the requirements on the network that derive from the

fact that an ISDN interface is used rather than the standard A-interface. This ETS is based on the

DECT/GSM interworking profile specifications ETS 300 466 [1] and ETS 300 370 [2] and on the DECT

and ISDN interworking for end system configuration ETS 300 434 [3].

NOTE 1: Interconnection of GSM PLMN and DECT access network elements via interfaces

other than the ISDN interface (e.g. the A-interface) is outside the scope of this ETS.

This ETS and the corresponding stage 2 standard specify the requirements for:
- the protocols for mobility management functions across the ISDN interface; and

- the DECT access network interworking/mappings for mobility management functions across the

ISDN interface; and

- the additions to the ISDN protocols for the support of basic telephony services as specified in

ETS 300 403-1 [4].

The DECT access network interworking/mappings for DECT and ISDN interworking are specified in

ETS 300 434 [3].

The DECT access protocols and Portable Part (PP) interworking/mappings necessary for the support of

basic telephony services are specified in ETS 300 370 [2] and ETS 300 444 [5].

Interaction with services/supplementary services are outside the scope of this ETS.

Handover among DECT cells and GSM cells as well as handover among DECT cells connected to

different DECT access networks, which are individually linked to a Mobile Switching Centre (MSC), is

outside the scope of this ETS.
Definition and applicability

This ETS describes how users with DECT PPs are enabled to access to GSM services and to make calls

from and to receive calls at any location where:
a) DECT radio coverage is provided; and
b) access is allowed to the user.

The application of an ISDN interface between GSM PLMN and DECT access network elements as

opposed to the A-interface introduces the capability for GSM service providers to offer their services by

making use of the DECT radio equipment of existing DECT access networks having implemented ISDN

interfaces.

NOTE 2: The DECT access network can be owned by the GSM service provider but it could

also be a Private Automatic Branch Exchange (PABX) or private network providing
transparent access to GSM.

Provided this, the GSM user accesses his/her telecommunication services in any DECT radio covered

location where access is allowed. The DECT/GSM network keeps track of the terminals location

throughout the entire network.

Furthermore, conformance to this ETS is met by conforming to the stage 3 standards with the field of

application appropriate to the equipment being implemented. Therefore no method of testing is provided

for this ETS.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of this ETS, the following definitions apply:

DECT access network: Physical entity that contains all of the elements of a DECT Fixed Part (FP) and

that is attached to a GSM MSC.

NOTE 1: A DECT access network provides a transparent access to the services of the GSM

PLMN. This does however not exclude that it may in addition provide services and
switching capabilities to its own users.

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

additional implementation specific elements.

DECT location area: The domain in which a DECT PP may receive and/or make calls as a result of a

single location registration in the DECT access network.

GSM location area: The domain in which a DECT PP may receive and/or make calls as a result of a

single location updating in the GSM network.
NOTE 3: A GSM location area may cover more than one DECT location area.

GSM service provider: An administration which offers global mobile telecommunication services to its

subscribers.

GSM services: Services which are offered to the subscriber/user by a GSM Service Provider and which

are defined by the appropriate GSM specifications.
