23、incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. y the third digit is incremented when editorial only changes have been incorporated in the specification. ETSI (GSM 01.48 version 6.0.1 Release 1997) 6 ETSI TS 1 O1 623 V6.0.1 (2001-02) 1 Scope The pres
24、ent document provides a study, which proves the feasibility of ISDN-based DECT/GSM interworking to support roaming of users of cordless DECT terminals between public GSM networks and private DECT networks via an ISDN-based interface. The study is aiming at teleservice speech and supplementary servic
25、es. Data, fax and other teleservices are out of scope. In order to limit the amount of work for subsequent specifications to what is achievable within a reasonable timeframe, this feasibility study considers very complex functionality, e.g. inter-network handover, to be out of scope. Commercial viab
26、ility and demand has to be considered by GSM MOU Association. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present documen t.

38、egrated Services Network Private Integrated Network Exchange Subscriber Identity Module 5 Introduction The sophisticated business user is seen as the most promising group of users. DECT systems initially serve business users with on-site PBX systems, but those users will also want to roam to GSM sys
39、tems. GSM operators may want to provide roaming service to business DECT users within islands of coverage, progressing to ubiquitous coverage with full mobility in pedestrian locations. The vast majority of public users will not be for public use only, but will be users from business environment for
40、 whom the public roaming is a key benefit of their DECT equipment. In large business applications, mobility must provide not only full roaming capability within a campus with multiple buildings, but also roaming from public systems to provide call originating and terminating capability within any pr
41、ivate business system. Also, typically, the business user will want to use his DECT terminal while attending a meeting at a hotel, having lunch with business associates, etc. These full levels of mobility require full interworking between public and private systems for user convenience. Also, in com
42、parison to wired systems, the business user will require speech quality at least as good as known from wired systems, which is a key capability of DECT, and security of the conversation. Therefore, encryption will be a frequently demanded feature. ETSI (GSM 01.48 version 6.0.1 Release 1997) 8 ETSI T
43、S 1 O1 623 V6.0.1 (2001-02) Dual mode handsets comprising DECT and GSM in one handset allow the service area to be global, and at the same time in-door coverage could be provided at appropriate costs. The DECT standard defines cordless access to various networks, public and private ISDN and non-ISDN
44、. DECT access to GSM was specified by RES3/SMG3 based on an A-Interface 2. An additional interface between GSM and DECT systems based on an ISDN-interface would allow attachment of not only public access systems, but in addition of small and big DECT wireless PINXs. ISDN-based interfaces are availab
45、le in all PINXs. The A-interface as specified for DECT/GSM interworking need not to be changed. Various scenarios could be supported, such as attachment of DECT equipment to GSM/MSC via PINX equipment which provides DECT Cluster Control Functions (3, 4), and DECT equipment attached to a PISN, and th
46、e PISN to GSM network. Since ISDN-based interfaces are available in all PINXs, an ISDN-based interface between DECT and GSM systems should be supported. Based on market requirements and a request from the Strategic Review Committee, a TCR-TR has been produced by ETSI NA (TCR-TR 013) on Network Suppo
47、rt of cordless terminal mobility i. This report provides an outline of technical solutions requiring standards to enable users of cordless terminals to roam between public (ISDNPSTN, GSM) and private networks. A Joint Management Group has been formed on Cordless Terminal Mobility (JMG CTM) to suppor
48、t cordless terminal mobility in fixed ISDNPSTN networks, however, excluding GSM. This report reuses i as much as possible, limiting the issue to DECT equipment / private DECT networks and GSM, extending the considered aspects by work done since then in other ETSI STCs, e.g. BTC1 (5, 6), or by aspect
49、s felt necessary in addition. To decide on the feasibility of the complete scope of the Work Item it is also required to address network aspects which may have to be reviewed by SMG3. Responsibility of standardization groups are indicated in Clause 6 on Scenarios and associated figure (RES on DECT side, SMG on GSM network side, SPSSECMA TC32 TG14 for the ISDN-based interface (see also 8.2.3). 6 Scenarios 6.1 Basic DECT / GSM scenarios The scenarios described are depicted in the attached figure.
