Foreword
This European Telecommunication Standard (ETS) has been produced by the Radio Equipment and
Systems (RES) Technical Committee of the European Telecommunications Standards Institute (ETSI).
Proposed transposition dates
Date of latest announcement of this ETS (doa): 31 Octobre 1995
Date of latest publication of new National Standard
or endorsement of this ETS (dop/e): 30 April 1996
Date of withdrawal of any conflicting National Standard (dow): 30 April 1996
Introduction
This ETS is a part of a set of standards for the DECT/GSM IWP concept that includes:
- General description of service requirements, functional capabilities and information flows;
- Access and mapping (protocol/procedure description for 3,1 kHz speech service), (this ETS);
- Support of GSM Phase 2 supplementary services (for further study);
- Fixed Interconnection (for further study).
This ETS is based on Digital European Cordless Telecommunications (DECT) Common Interface
specification ETS 300 175 [1] to [8] to enable DECT terminals to inter-work 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) [9] to enable the same
DECT/GSM terminal to inter-work with a DECT Fixed Part (FP) complying to the GAP requirements,
irrespective of whether this FP provides residential, business or public access services.
This ETS utilises in addition to the only GAP related features and procedures the following:
- GSM authentication;
- derivation of the DECT ciphering key from the respective GSM cipher key;
- the GSM International Mobile Subscriber Identity (IMSI) and Temporary Mobile Subscriber Identity
(TMSI); and
- the GSM Location Area Identity (LAI).
This ETS defines a general purpose, but strict, mobility profile in terms of features, procedures, data
structures, information elements and fields within the information elements at the DECT air interface in
order to achieve full inter-operability between equipment i.e. DECT systems and terminals, which fulfil the
requirements of this ETS. This ETS also fulfils the minimum requirements of the GAP enabling backwards
compatibility with the respective equipment.

1 Scope
This ETS specifies the DECT access protocols and FP and Portable Part (PP) inter-working/mappings
necessary to ensure that the Global System for Mobile communications (GSM) basic voice telephony
service can be provided over DECT. To enable DECT terminals to inter-work with DECT systems which
are connected to the GSM infrastructure, from the DECT side this ETS is based on the GAP [9] and on
the DECT Common Interface specification ETS 300 175 [1] to [8] (for the cases not covered by GAP),
from GSM side this ETS assumes inter-working with GSM Public Land Mobile Network (PLMN) phase 2.
An air-interface profile is specified for a particular set of GSM services so that inter-operability of DECT
equipment for these services can be achieved. Inter-working 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. Inter-working functions/mappings for the PP are specified for
MSC environment.
The provision of the GSM Subscriber Identity Module (SIM) and DECT Authentication Module (DAM) with
the GSM Application (GA) within the DECT portable are also considered.
Mobility Management (MM) and circuit-switched Call Control (CC) functionality are covered.
The RR-Management and other GSM specific functionality at the GSM A-interface, interfaces to non
GSM-networks, supplementary services, and other GSM data services are outside the scope of this ETS.
A PP conforming to this ETS should be capable of distinguishing a FP conforming to this ETS from a FP
conforming to the GAP and to access and to react upon accordingly.
