Foreword
This second edition European Telecommunication Standard (ETS) has been produced by the Digital
Enhanced Cordless Telecommunications (DECT) Project of the European Telecommunications
Standards Institute (ETSI).
Transposition dates
Date of adoption of this ETS: 23 January 1998
Date of latest announcement of this ETS (doa): 31 May 1998
Date of latest publication of new National Standard
or endorsement of this ETS (dop/e): 30 November 1998

Introduction
This ETS is a part of a set of standards for the Digital Enhanced Cordless Telecommunications / Global
System for Mobile communications (DECT/GSM) Interworking Profile (IWP) concept that includes:
- general description of service requirements, functional capabilities and information flows,
ETS 300 466 [12];
- access and mapping (protocol/procedure description for 3,1 kHz speech service), (this ETS);
- GSM Phase 2 supplementary services implementation, ETS 300 703 [21];
- GSM Mobile Switching Centre (MSC) – DECT Fixed Part (FP), Fixed Interconnection,
ETS 300 499 [13];
- implementation of bearer services, ETS 300 756 [22];
- implementation of short message services, point to point and cell broadcast, ETS 300 764 [23];
- implementation of facsimile group 3, (ETS 300 792 [24]).
This ETS is based on 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 GSM core infrastructure.
In addition, this ETS is based on the DECT Generic Access Profile (GAP), EN 300 444 [10] to enable the
same DECT/GSM terminal to interwork with a DECT 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 [26] and TBR 10 [27].
This ETS utilizes, in addition to the GAP only 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);
- the GSM Location Area Identity (LAI);
- subscription management by use of Subscriber Identity Module (SIM); and
- adding/deleting a Public Land Mobile Network (PLMN) in the SIM forbidden PLMN list.
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.
Information on DECT access to the GSM PLMN may be found in ETR 159 [33]. Further details on the
DECT system may be found in ETR 015 [29], ETR 043 [30], and ETR 056 [31], and in ETS 300 176 [9].
