No guarantee can be given as to the existence of any IPRs which are, or may be, or maybecome, essential to the present document.ForewordThis Technical Report (TR) has been produced by ETSI Project Digital Enhanced Cordless Telecommunications(DECT).IntroductionThe primary objective of this document is to examine the technical issues relating to dual mode (combined DigitalEnhanced Cordless Telecommunications/Global System for Mobile communications (DECT/GSM)) terminals in orderto guide future work in this area.The substantive clauses of this document are as follows:Clause 5 examines the various configurations and scenarios foreseen for Dual Mode Terminals (DMTs). The followingaspects are considered:-the constraints resulting from the radio system architecture employed;-the different combinations of subscription types that may be used;-the possible network configurations which may be used to support a dual mode service;-the different service packages that an operator may provide to its customers.Clauses 6, 7, 8 and 9 attempt to identify the technical areas that has to be addressed by the TBR for DMTs.Clause 6 addresses the requirements for protection of the spectrum.Clause 7 addresses the requirements for protection of the network.Clause 8 examines general protocol issues which need consideration in order to ensure interoperability.Clause 9 considers the telephony requirements which have to be met.Clause 10 concludes on type approval aspects basic DMTs.PSIST TR 101 072:2000



TR 101 072 V1.1.1 (1997-06)61ScopeTo investigate radio and network aspects and clarifying the possibilities as well as the problems related to dual-modeterminals. This document focuses on possible early implementations and will form the basis for the first edition ofTBR 39 [28] in the sense that it identifies how basic Dual Mode Terminals (DMTs) can be type approved using existingTBRs. For Global System for Mobile communications (GSM), both phase 1 and phase 2 specifications are considered.Basic DMTs are considered to comprise of both Digital Enhanced Cordless Telecommunications (DECT) and GSMparts of which only one at the time is to be active. Advanced dual-mode terminals, where the DECT and GSM parts arefurther integrated or where the DECT and GSM parts can be active at the same time, will be considered inDTR/DECT-010096 [35].The same considerations apply for dual-mode DECT/DCS1800 terminals and for DECT/GSM/DCS1800 dualmode/dual band terminals. The term GSM is considered to cover all the frequency bands, and combinations offrequency bands allowed for GSM type equipment, i.e. P-GSM, E-GSM, R-GSM, DCS1800 or dual band GSM/DCS.NOTE:A terminal comprising multiple GSM parts operating on different frequency bands is considered as a dualband terminal. A terminal comprising both DECT and GSM parts is referred to as a DMT. A dualmode/dual band terminal is a terminal comprising a DECT part and a GSM/DCS1800 dual band part.This document states the assumptions to be made for the first edition of TBR 39 [28] and attempts to identify if furtherdual mode standardization is needed.2ReferencesReferences may be made to:a)specific versions of publications (identified by date of publication, edition number, version number, etc.), inwhich case, subsequent revisions to the referenced document do not apply; orb)all versions up to and including the identified version (identified by "up to and including" before the versionidentity); orc)all versions subsequent to and including the identified version (identified by "onwards" following the versionidentity); ord)publications without mention of a specific version, in which case the latest version applies.A non-specific reference to an ETS shall also be taken to refer to later versions published as an EN with the samenumber.[1]ETS 300 175-1: "Digital Enhanced Cordless Telecommunications (DECT); Common Interface(CI); Part 1: Overview".[2]ETS 300 175-2: "Digital Enhanced Cordless Telecommunications (DECT); Common Interface(CI); Part 2: Physical layer (PHL)".[3]ETS 300 175-3: "Digital Enhanced Cordless Telecommunications (DECT); Common Interface(CI); Part 3: Medium Access Control (MAC) layer".[4]ETS 300 175-4: "Digital Enhanced Cordless Telecommunications (DECT); Common Interface(CI); Part 4: Data Link Control (DLC) layer".[5]ETS 300 175-5: "Digital Enhanced Cordless Telecommunications (DECT); Common Interface(CI); Part 5: Network (NWK) layer".[6]ETS 300 175-6: "Digital Enhanced Cordless Telecommunications (DECT); Common Interface(CI); Part 6: Identities and addressing".[7]ETS 300 175-7: "Digital Enhanced Cordless Telecommunications (DECT); Common Interface(CI); Part 7: Security features".PSIST TR 101 072:2000

For example aterminal comprising of GSM and DCS1800 parts.Dual Mode Terminal (DMT): A terminal comprising both DECT and GSM parts.dual mode/dual band terminal: A terminal comprising both DECT and multiple GSM parts operating on differentfrequency bands. It is considered as a terminal comprising both DECT and dual band (e.g. GSM/DCS1800) parts.Fixed Part (DECT Fixed Part) (FP): A physical grouping that contains all of the elements in the DECT networkbetween the local network and the DECT air interface.location registration: The process by which the terminal informs the network of its presence within a particularlocation area.Network Termination Point (NTP): Is the point that defines the border between the equipment provided by thenetwork operator and the customer premises equipment.Portable Part (DECT Portable Part) (PP): A physical grouping that contains all elements between the user and theDECT air interface. PP is a generic term that may describe one or several physical pieces.Radio Fixed Part (RFP): One physical sub-group of a FP that contains all the radio end points (one or more) that areconnected to a single system of antennas.PSIST TR 101 072:2000



TR 101 072 V1.1.1 (1997-06)10subscription registration: The infrequent process whereby a subscriber obtains access rights to one or more FPs.NOTE 4:Subscription registration is usually required before a user can make or receive calls.subscription load/modify: A procedure of loading subscription registration data in a PP or CTA in real-time over theair interface.Wireless Relay Station (WRS): a physical grouping that combines elements of both Portable radio Terminations (PTs)and Fixed radio Terminations (FTs) to relay information on a physical channel from one DECT termination to a physicalchannel to another DECT termination.NOTE 5:The DECT termination can be a PT or an FT or another WRS.3.3GSM abbreviations and definitionsDefinition and specific GSM abbreviations may be found in ETR 100 [29].4Terminology used in this documentDECT and GSM standards often use different terminology for equivalent functions. Since this document will be read byboth experts in GSM and experts in DECT, this clause tries to clarify some of the vocabulary used. Similar DECT andGSM definitions are not necessarily strictly equivalent, it has been chosen sometimes to use general formulations. If dualmode standards are to be produced, a common terminology needs to be defined.Exact GSM terminology can be found in GSM 03.22 (ETS 300 535 [13]). The DECT terminology can be found in theDECT CI specifications (ETS 300 175, parts 1 to 8 [1] - [8]).Table 1: Comparison of DECT and GSM terminology as used with respect to DMTsDECT termGSM termExplanationPPMobile stationThe combination of mobile termination equipment, subscription identityequipment and any required terminal equipment.Often through this document the word "terminal" is used for those terms.RFPBase stationThe physical equipment providing the elementary part of coverage.The word "cell" is not used in DECT, but often through this document theword "cell" is used for the coverage area of a RFP/base station.Active unlockedscanNetwork searchThe process by which a terminal scans all possible frequencies foravailable networks (Public Land Mobile Networks (PLMNs) in GSM).Often through this document the word "scanning" is used for those terms.Network selectionThe process by which a terminal chooses a network.In GSM a Mobile Station manually or automatically chooses a network(PLMN in GSM) from a list of those detected during Network search.In DECT this process is implementation dependant and uses the activeunlocked scan.Often through this document the words "network selection".Location areaLocation areaA group of cells all of whose broadcast location identities are the same.Location registrationLocation updateThe process by which the terminal informs the network of its presencewithin a particular location area.Both terms are used through the document.Attach/DetachAttach/detachAttach is the process whereby a terminal within coverage area of a systemto which it has access rights, notifies the system that it is operative.The reverse process is detach, which reports the terminal as inoperative(note).Idle lockedIdle modeThe state a terminal is in when it is operational but is not in any transactionwith the network (call, location update, etc.).Active lockedDedicated modeThe state a terminal is in when it has started a transaction with the network.NOTE:There is no procedure over the air interface for detach indication in Generic Access Profile (GAP).PSIST TR 101 072:2000



TR 101 072 V1.1.1 (1997-06)114.1Distinguishing access technology from network typeThe intention of this subclause is to clearly distinguish between the air interface used and the core network providingmobility.The word DECT is used to refer to the DECT air interface or the access network related to the DECT air interface.The word GSM is used to refer to the GSM or DCS1800 air interface and the related access network.The term Access Rights Identifier (ARI) A/B/C is used to refer to a network subscription that can be accessed using theDECT air interface only. It is also used to refer to a system or network requiring only basic GAP protocols or a closelyrelated protocol such as the Cordless Terminal Mobility (CTM) Access Profile (CAP). An ARI A/B/C subscriptioncannot be used to access a PLMN.NOTE 1:The ARI is used by the PT to determine if it has permission to access a FT. Types A, B, C are intended forresidential, business and public access applications respectively. ARI D is specifically intended to be usedin conjunction with DECT/GSM interworking applications.NOTE 2:An ARI A
