Digital Enhanced Cordless Telecommunications (DECT); Global System for Mobile communications (GSM); DECT/GSM integration based on dual-mode terminals
To secify radio and network aspects related to dual-mode terminals. This EN will, in conjuction with other standards and TBRs, form the basis for the second edition of TBR 39 (converted to Harmonized EN 301 439 v1.2.x), i.e. basic dual-mode terminals that only consist of a DECT art and a GSM part and that may automatically switch between DECT and GSM modes. (Advanced dual-mode terminals, where the DECT and GSM parts are further integrated, will be considered in a TR (DTR/DECT-010096). The same considerations apply for dual-mode DECT/DCS1800 terminals and for DECT/GSM/DCS1800 dual mode/dual band terminals. The term GSM is considered to cover all the frequency bands, and combinations of frequency bands allowed for GSM type equipment, i.e. P-GSM, E-GSM, R-GSM, DCS1800 or dual band GSM/DCS.

The DMT is ineither GSM or DECT mode or it can have both modes activated at the same time. In each mode, the DMT shall operateas the corresponding single mode terminal and shall fully comply with the relevant standards for that single modeterminal (for GSM see references in ETS 300 607-1 [4]; for DECT see EN 300 175 parts 1 to 8 [8] to [15] andEN 300 444 [2], EN 300 824 [5] or ETS 300 434-2 [1]), unless specified in the present document.The DMT shall give an indication to the user of the mode(s) currently in use.When one mode is being activated the DMT shall operate like a single mode terminal that is switching on. When onemode is being deactivated the DMT shall operate like a single mode terminal that is switching off.Location registration within each mode shall be performed according to the relevant standards for single-mode terminals(for GSM see references in ETS 300 607-1 [4]; for DECT see EN 300 175 parts 1 to 8 [8] to [15] and EN 300 444 [2],EN 300 824 [5] or ETS 300 434-2 [1]) and the behaviour when switching modes is the same as when one single-modeterminal is switched-off and the second is switched-on:-when deactivating one mode, the applicable behaviour shall be the one specified in the relevant standards for theswitch off (e.g. detach procedure, if applicable), for GSM see references in ETS 300 607-1 [4]; for DECT seeEN 300 175 parts 1 to 8 [8] to [15] and EN 300 444 [2], EN 300 824 [5] or ETS 300 434-2 [1];-when activating one mode, the applicable behaviour shall be the one specified in the relevant standards for theswitch on (e.g. attach procedure, if applicable), for GSM see references in ETS 300 607-1 [4]; for DECT seeEN 300 175 parts 1 to 8 [8] to [15] and EN 300 444 [2], EN 300 824 [5] or ETS 300 434-2 [1].4.2Dual mode operationThe following ways of operation are possible for a DMT:-Manually switched operation (the DMT behaves as a GSM MS or as a DECT PP):-GSM-only mode;-DECT-only mode.-Automatically switched operation (the DMT behaves as a GSM MS or as a DECT PP and can switchautomatically between GSM and DECT modes):-old mode is switched off before new mode is switched on.-Parallel operation (both DECT and GSM modes are activated and the DMT is location registered both in aGSM PLMN and with a DECT FP):-active communication is only possible in one mode at the time; or-active communication is possible in both modes at the same time.Manually switched operation shall always be implemented in a DMT. In addition, automatically switched operationand/or parallel operation can be implemented.SIST EN 301 242:2000
ETSIETSI EN 301 242 V1.2.2 (1999-09)10NOTE:Here, and in the following, referring to manually switched operation means both GSM-only andDECT-only while referring to parallel operation means either single active mode or double active modes.It shall be possible for the user to select any of the implemented ways of operation. When changing way of operation,the relevant DECT and GSM switch-on and switch-off procedures shall be performed if necessary.The DMT should use the last way of operation, as the default way of operation, at every switch-on.4.2.1General on manually switched operationWhen in manually switched operation, the DMT can only be switched manually between GSM mode and DECT mode.The decision of the user to switch mode may be based on the result of a background scan.4.2.1.1GSM-only modeAfter a manual switch to GSM mode, the DMT shall behave as a GSM MS.4.2.1.2DECT-only modeAfter a manual switch to DECT mode, the DMT shall behave as a DECT PP.4.2.2General on automatically switched operationIn automatically switched operation the DMT is registered in only one network at the time using either DECT or GSMmode. The DMT switches automatically between GSM and DECT mode either due to loss of coverage / service orbecause preferred coverage has been identified (during background scanning) in the mode other than the one it iscurrently in. The frequency of mode switching based on background scanning is restricted.When in automatically switched operation, the DMT can be switched manually between GSM mode and DECT modeonly by changing to manually switched operation.When switching mode, the DMT switches the first mode off before the second mode is switched on.The requirements on the active mode shall be met also when the DMT is background scanning for coverage in the othermode.4.2.3General on parallel operationIn parallel operation the DMT is normally registered in two networks at the time using both DECT and GSM mode. TheDMT shall not switch between GSM and DECT modes unless it can meet the requirements on automatically switchedoperation. In case of loss of coverage in one mode, the DMT shall operate according to the idle mode procedures forthat mode.When in parallel operation, the DMT can be forced into DECT or GSM mode only by changing to manually switchedoperation.4.2.3.1Single active modeIn parallel operation with a single active mode the DMT shall simultaneously meet idle mode requirements of bothDECT and GSM. When the DMT is in active communication in one mode, it shall not transmit in the other mode andshall behave as if it was out of coverage in that mode.NOTE:E.g. when the DMT is active in a GSM call, it does not respond to DECT pagings.The normal requirements which apply to a GSM MS shall apply to the DMT also when the DECT receiver is active.The normal requirements which apply to a DECT PP shall apply to the DMT also when the GSM receiver is active.SIST EN 301 242:2000
ETSIETSI EN 301 242 V1.2.2 (1999-09)114.2.3.2Double active modesWhen in parallel operation with double active modes, the DMT behaves simultaneously both as a GSM MS and a DECTPP except for cases where some physical units (e.g. microphone and loudspeaker) are shared.The DMT shall simultaneously meet idle mode and active mode requirements of both DECT and GSM. When the DMTis in active communication in one mode, it can transmit in the other mode and shall be capable of handling simultaneouscommunication in both modes.The normal requirements which apply to a GSM MS shall apply to the DMT also when the DECT transceiver is active.The normal requirements which apply to a DECT PP shall apply to the DMT also when the GSM transceiver is active.If parallel operation with double active modes is implemented then functionality to handle a second incoming callshould be implemented.4.3Service accessA DMT with valid International Mobile Subscriber Identity (IMSI) and/or Access Rights Identity / Portable AccessRights Key (ARI/PARK) pairs may access service in the areas authorized by the entitlement of the subscriptions.NOTE 1:DECT ARI class D is not covered in the present document.Entry of the Personal Identification Number (PIN) shall be done according to GSM 02.30 (ETS 300 511 [3]) at switchon of the DMT with a Subscriber Identity Module (SIM) in or at insertion of the SIM when the DMT is switched on. Atthe time of entering the PIN the DMT may be in DECT or GSM mode.NOTE 2:In GSM mode a SIM card is mandatory except for emergency calls. In DECT mode SIM access is needed,e.g. for the SIM phone book.Switching of modes may be done without entering the PIN again. Unblocking PIN or PIN2 need not be supported inDECT mode.4.4DECT profilesIf the voice telephony service is implemented in the DECT part of the DMT it shall be based on at least one of theDECT profiles: Generic Access Profile (GAP) (EN 300 444 [2]); Cordless Terminal Mobility (CTM) Access Profile(CAP) (EN 300 824 [5]) or ISDN Access Profile (IAP) (ETS 300 434-2 [1]).The DECT/GSM IWP (ETR 341 [6]) is not covered by the present document. Scenarios for DMTs with DECT/GSMIWP are given in TR 101 176 [26].5Requirements on manually switched operationWhen in manually switched operation, the DMT is in either GSM or DECT mode. When in either mode, the DMT shalloperate as the corresponding single mode terminal and shall fully comply with the relevant standards for that singlemode terminal (for GSM see references in ETS 300 607-1 [4]; for DECT see EN 300 175 parts 1 to 8 [8] to [15] andEN 300 444 [2], EN 300 824 [5] or ETS 300 434-2 [1]).5.1Manual mode selectionWhen in manually switched operation the user shall be given the opportunity to change the chosen mode at any timeexcept when in active communication. Background scanning may be implemented, e.g. to give notification to the user onthe availability of other networks. A background scan may be initiated manually or automatically. If backgroundscanning is implemented then it shall be implemented according to subclause 6.2.2.2.SIST EN 301 242:2000
ETSIETSI EN 301 242 V1.2.2 (1999-09)12When the DMT switches mode it shall operate as two single mode terminals where the first is switched off before thesecond is switched on, i.e. it shall deactivate the first mode before activating the second mode. When one mode isactivated the DMT shall operate like a single mode terminal that is switched on. When one mode is deactivated theDMT shall operate like a single mode terminal that is switched off.5.2Procedures5.2.1At switch-onIf the DMT was in manually switched operation when switched-off it shall go active (at switch-on) in the same mode itwas active in when switched-off.5.2.2User re-selection of modeThe user may, at any time when not in active communication, initiate re-selection of mode. When the re-selection ofmode is initiated, the DMT could initiate a background scan if implemented but can go directly to the other mode. If asuitable network is identified during the background scan, the user can initiate a switch to the other mode.6Requirements on automatically switched operationThis clause covers the requirements on DMTs with the automatic switched operation implemented, i.e. DMTs whereonly one mode (DECT or GSM) is activated at the time.6.1GeneralThe DMT is in either GSM or DECT mode. When in either mode, the DMT shall operate as the corresponding singlemode terminal (except that it may perform background scanning) and shall fully comply with the relevant standards forthat single mode terminal (for GSM see references in ETS 300 607-1 [4]; for DECT see EN 300 175 parts 1 to 8 [8]to [15] and EN 300 444 [2], EN 300 824 [5] or ETS 300 434-2 [1]), unless specified in this subclause.When one mode is activated the DMT shall operate like a single mode terminal that is switched on. When one mode isdeactivated the DMT shall operate like a single mode terminal that is switched off. When the DMT switches mode, itshall deactivate the first before activating the second, and shall operate a

The DMT is ineither GSM or DECT mode or it can have both modes activated at the same time. In each mode, the DMT shall operateas the corresponding single mode terminal and shall fully comply with the relevant standards for that single modeterminal (for GSM see references in ETS 300 607-1 [4]; for DECT see EN 300 175 parts 1 to 8 [8] to [15] andEN 300 444 [2], EN 300 824 [5] or ETS 300 434-2 [1]), unless specified in the present document.The DMT shall give an indication to the user of the mode(s) currently in use.When one mode is being activated the DMT shall operate like a single mode terminal that is switching on. When onemode is being deactivated the DMT shall operate like a single mode terminal that is switching off.Location registration within each mode shall be performed according to the relevant standards for single-mode terminals(for GSM see references in ETS 300 607-1 [4]; for DECT see EN 300 175 parts 1 to 8 [8] to [15] and EN 300 444 [2],EN 300 824 [5] or ETS 300 434-2 [1]) and the behaviour when switching modes is the same as when one single-modeterminal is switched-off and the second is switched-on:-when deactivating one mode, the applicable behaviour shall be the one specified in the relevant standards for theswitch off (e.g. detach procedure, if applicable), for GSM see references in ETS 300 607-1 [4]; for DECT seeEN 300 175 parts 1 to 8 [8] to [15] and EN 300 444 [2], EN 300 824 [5] or ETS 300 434-2 [1];-when activating one mode, the applicable behaviour shall be the one specified in the relevant standards for theswitch on (e.g. attach procedure, if applicable), for GSM see references in ETS 300 607-1 [4]; for DECT seeEN 300 175 parts 1 to 8 [8] to [15] and EN 300 444 [2], EN 300 824 [5] or ETS 300 434-2 [1].4.2Dual mode operationThe following ways of operation are possible for a DMT:-Manually switched operation (the DMT behaves as a GSM MS or as a DECT PP):-GSM-only mode;-DECT-only mode.-Automatically switched operation (the DMT behaves as a GSM MS or as a DECT PP and can switchautomatically between GSM and DECT modes):-old mode is switched off before new mode is switched on.-Parallel operation (both DECT and GSM modes are activated and the DMT is location registered both in aGSM PLMN and with a DECT FP):-active communication is only possible in one mode at the time; or-active communication is possible in both modes at the same time.Manually switched operation shall always be implemented in a DMT. In addition, automatically switched operationand/or parallel operation can be implemented.SIST EN 301 242:2000
ETSIETSI EN 301 242 V1.2.2 (1999-09)10NOTE:Here, and in the following, referring to manually switched operation means both GSM-only andDECT-only while referring to parallel operation means either single active mode or double active modes.It shall be possible for the user to select any of the implemented ways of operation. When changing way of operation,the relevant DECT and GSM switch-on and switch-off procedures shall be performed if necessary.The DMT should use the last way of operation, as the default way of operation, at every switch-on.4.2.1General on manually switched operationWhen in manually switched operation, the DMT can only be switched manually between GSM mode and DECT mode.The decision of the user to switch mode may be based on the result of a background scan.4.2.1.1GSM-only modeAfter a manual switch to GSM mode, the DMT shall behave as a GSM MS.4.2.1.2DECT-only modeAfter a manual switch to DECT mode, the DMT shall behave as a DECT PP.4.2.2General on automatically switched operationIn automatically switched operation the DMT is registered in only one network at the time using either DECT or GSMmode. The DMT switches automatically between GSM and DECT mode either due to loss of coverage / service orbecause preferred coverage has been identified (during background scanning) in the mode other than the one it iscurrently in. The frequency of mode switching based on background scanning is restricted.When in automatically switched operation, the DMT can be switched manually between GSM mode and DECT modeonly by changing to manually switched operation.When switching mode, the DMT switches the first mode off before the second mode is switched on.The requirements on the active mode shall be met also when the DMT is background scanning for coverage in the othermode.4.2.3General on parallel operationIn parallel operation the DMT is normally registered in two networks at the time using both DECT and GSM mode. TheDMT shall not switch between GSM and DECT modes unless it can meet the requirements on automatically switchedoperation. In case of loss of coverage in one mode, the DMT shall operate according to the idle mode procedures forthat mode.When in parallel operation, the DMT can be forced into DECT or GSM mode only by changing to manually switchedoperation.4.2.3.1Single active modeIn parallel operation with a single active mode the DMT shall simultaneously meet idle mode requirements of bothDECT and GSM. When the DMT is in active communication in one mode, it shall not transmit in the other mode andshall behave as if it was out of coverage in that mode.NOTE:E.g. when the DMT is active in a GSM call, it does not respond to DECT pagings.The normal requirements which apply to a GSM MS shall apply to the DMT also when the DECT receiver is active.The normal requirements which apply to a DECT PP shall apply to the DMT also when the GSM receiver is active.SIST EN 301 242:2000
ETSIETSI EN 301 242 V1.2.2 (1999-09)114.2.3.2Double active modesWhen in parallel operation with double active modes, the DMT behaves simultaneously both as a GSM MS and a DECTPP except for cases where some physical units (e.g. microphone and loudspeaker) are shared.The DMT shall simultaneously meet idle mode and active mode requirements of both DECT and GSM. When the DMTis in active communication in one mode, it can transmit in the other mode and shall be capable of handling simultaneouscommunication in both modes.The normal requirements which apply to a GSM MS shall apply to the DMT also when the DECT transceiver is active.The normal requirements which apply to a DECT PP shall apply to the DMT also when the GSM transceiver is active.If parallel operation with double active modes is implemented then functionality to handle a second incoming callshould be implemented.4.3Service accessA DMT with valid International Mobile Subscriber Identity (IMSI) and/or Access Rights Identity / Portable AccessRights Key (ARI/PARK) pairs may access service in the areas authorized by the entitlement of the subscriptions.NOTE 1:DECT ARI class D is not covered in the present document.Entry of the Personal Identification Number (PIN) shall be done according to GSM 02.30 (ETS 300 511 [3]) at switchon of the DMT with a Subscriber Identity Module (SIM) in or at insertion of the SIM when the DMT is switched on. Atthe time of entering the PIN the DMT may be in DECT or GSM mode.NOTE 2:In GSM mode a SIM card is mandatory except for emergency calls. In DECT mode SIM access is needed,e.g. for the SIM phone book.Switching of modes may be done without entering the PIN again. Unblocking PIN or PIN2 need not be supported inDECT mode.4.4DECT profilesIf the voice telephony service is implemented in the DECT part of the DMT it shall be based on at least one of theDECT profiles: Generic Access Profile (GAP) (EN 300 444 [2]); Cordless Terminal Mobility (CTM) Access Profile(CAP) (EN 300 824 [5]) or ISDN Access Profile (IAP) (ETS 300 434-2 [1]).The DECT/GSM IWP (ETR 341 [6]) is not covered by the present document. Scenarios for DMTs with DECT/GSMIWP are given in TR 101 176 [26].5Requirements on manually switched operationWhen in manually switched operation, the DMT is in either GSM or DECT mode. When in either mode, the DMT shalloperate as the corresponding single mode terminal and shall fully comply with the relevant standards for that singlemode terminal (for GSM see references in ETS 300 607-1 [4]; for DECT see EN 300 175 parts 1 to 8 [8] to [15] andEN 300 444 [2], EN 300 824 [5] or ETS 300 434-2 [1]).5.1Manual mode selectionWhen in manually switched operation the user shall be given the opportunity to change the chosen mode at any timeexcept when in active communication. Background scanning may be implemented, e.g. to give notification to the user onthe availability of other networks. A background scan may be initiated manually or automatically. If backgroundscanning is implemented then it shall be implemented according to subclause 6.2.2.2.SIST EN 301 242:2000
ETSIETSI EN 301 242 V1.2.2 (1999-09)12When the DMT switches mode it shall operate as two single mode terminals where the first is switched off before thesecond is switched on, i.e. it shall deactivate the first mode before activating the second mode. When one mode isactivated the DMT shall operate like a single mode terminal that is switched on. When one mode is deactivated theDMT shall operate like a single mode terminal that is switched off.5.2Procedures5.2.1At switch-onIf the DMT was in manually switched operation when switched-off it shall go active (at switch-on) in the same mode itwas active in when switched-off.5.2.2User re-selection of modeThe user may, at any time when not in active communication, initiate re-selection of mode. When the re-selection ofmode is initiated, the DMT could initiate a background scan if implemented but can go directly to the other mode. If asuitable network is identified during the background scan, the user can initiate a switch to the other mode.6Requirements on automatically switched operationThis clause covers the requirements on DMTs with the automatic switched operation implemented, i.e. DMTs whereonly one mode (DECT or GSM) is activated at the time.6.1GeneralThe DMT is in either GSM or DECT mode. When in either mode, the DMT shall operate as the corresponding singlemode terminal (except that it may perform background scanning) and shall fully comply with the relevant standards forthat single mode terminal (for GSM see references in ETS 300 607-1 [4]; for DECT see EN 300 175 parts 1 to 8 [8]to [15] and EN 300 444 [2], EN 300 824 [5] or ETS 300 434-2 [1]), unless specified in this subclause.When one mode is activated the DMT shall operate like a single mode terminal that is switched on. When one mode isdeactivated the DMT shall operate like a single mode terminal that is switched off. When the DMT switches mode, itshall deactivate the first before activating the second, and shall op
