Radio Equipment and Systems (RES);Digital European Cordless Telecommunications/Global System for Mobile communications (DECT/GSM) inter-working profile; Access and mapping (Protocol/procedure description for 3,1 kHz speech service)

Based on the GAP, develop a DECT air interface profile to achieve interoperability between PPs & FPs where the FT is attached to the GSM infrastructure (e.g. GSM A-interface). The minimum service to be supported is speech.

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.
