20、November 1996 Blank page Page 7 GSM 01.48 Version 5.0.1 : November 1996 1 Scope This Global System for Mobile communications Technical Specification (GTS) provides a study which proves the feasibility of ISDN-based DECT/GSM interworking to support roaming of users of cordless DECT terminals between
21、public GSM networks and private DECT networks via an ISDN-based interface. The study is aiming at teleservice speech and supplementary services. 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 reason
22、able timeframe, this feasibility study considers very complex functionality, e.g. inter-network handover, to be out of scope. Commercial viability and demand has to be considered by GSM MOU Association. 2 References This GSM technical specification incorporates by dated and undated reference, provis

34、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 systems. GSM operators may w
35、ant 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 whom the public roaming
36、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 private business system. Al
37、so, 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 comparison to wired systems,
38、 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. Dual mode handsets comprising DECT and GSM in one handset allow the service a
39、rea 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. DECT access to GSM was specified by RES3/SMG3 based on an A-lnterface 2. An additional interface betwee
40、n 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 available in all PINXs. The A-interface as specified for DECT/GSM interworking need not to be changed. Various s
41、cenarios 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 Page 9 GSM 01.48 Version 5.0.1 : November 1996 PISN, and the PISN to GSM network. Since ISDN-based interfaces are ava
42、ilable 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 Support of cordless terminal mobility“ l. This report provides
43、 an outline of technical solutions requiring standards to enable users of cordless terminals to roam between public (ISDNIPSTN, GSM) and private networks. A Joint Management Group has been formed on Cordless Terminal Mobility (JMG CTM) to support cordless terminal mobility in fixed ISDN/PSTN network
44、s, however, excluding GSM. This report reusesl 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, SI), or by aspects felt necessary in addition. To decide on the feasibi
45、lity 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 Section 6 on Scenarios and associated figure (RES on DECT side, SMG on GSM network side, SPS5/ECMA TC32 TG14 for
46、 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. 1) DECT equipment attached to GSM/MSC: As already recognized, DECT systems could be used to complement GSM in traffic “hot spots“ requiring increased ca
47、pacity. In this scenario, only GSM databases are involved, and no databases at the periphery are required. 1 a) DECT equipment attached to GSM/MSC NOTE: This scenario is included here to give an overall view, but is not further addressed in this document, since it uses the A intedace. Reference is m
48、ade to RES3 standards on “DECT/GSM interworking profile“ 2, 7, 8. Ib) DECT equipment attached to GSM/MSC via PINX equipment providing DECT Cluster Control Functions GSM core services are provided to the users of cordless DECT terminals with GSM subscription, via co-operating GSM and DECT network ele
49、ments which are interconnected by means of an ISDN interface. In this scenario, the DECT network elements consist of PINX equipment, that is able to control DECT specific mobility and DECT intra-cell and intra-cluster handover. The DECT network elements may or may not be under the authority of a GSM network provider. NOTE: For this scenario reference is made to the current work within RES3 on ETSs “DECT access to GSM via ISDN“ (3 (stable draft, 4 (fairly stable draft). Interaction with supplementary services and charging principles are out of their scope. Based
