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 ba sis for the first edition of TBR 39, i.e. basic dual-mode terminals th at only consist of a DECT art and a GSM part and that may automaticall y switch between DECT and GSM modes. (Advanced dual-mode terminals, wh ere 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-G SM, DCS1800 or dual band GSM/DCS.

The purpose of the present document is to specify the additional requirements to the existing Global System for Mobile
communications (GSM) and Digital Enhanced Cordless Telecommunication (DECT) standards needed for DECT/GSM
Dual Mode Terminals (DMTs) that can perform background scanning and switch automatically between GSM and
DECT modes, but cannot be active in both modes at the same time.
For the DECT side, the DECT/GSM Interworking Profile (IWP) is not considered.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following definitions apply:
active communication: A state, where a communication link has been established between the DMT and a fixed part in
either GSM or DECT mode.
active mode: GSM or DECT mode after being selected and switch on procedures for that mode being performed.
background scanning: The process whereby a basic DMT attempts to identify the existence of stable networks in the
mode other than the one it is in to which the terminal has access rights.
basic dual mode terminal: A DMT that can only be in one mode at the time and that can be switched either manually
or automatically between modes. The basic DMT is always in one mode.
dual mode terminal: A terminal comprising both GSM and DECT parts.
GSM coverage: The sum of all GSM Public Land Mobile Network (PLMN) coverages where the DMT has at least
limited service.
GSM: In the present document, the GSM part of a DMT can be GSM 900, Digital Cellular System 1800 (DCS 1800) or
GSM/DCS dual band.
mode selection: A DMT based procedure, whereby operating mode, GSM or DECT, is chosen.
mode: A basic DMT is in either of the two modes GSM and DECT. In GSM mode the DMT behaves as a GSM Mobile
Station (MS) and in DECT mode the DMT behaves as a DECT Portable Part (PP).

4 General on DECT/GSM DMTs
A DMT is a terminal comprising both GSM and DECT parts, see TR 101 072 [7]. The DMT is in either GSM or DECT
mode. When in either mode, the DMT shall operate as the corresponding single mode terminal (except that it may
perform background scanning) and shall fully comply with the relevant standards for that single mode terminal (for
GSM see references in ETS 300 607-1 [4]; for DECT see EN 300 175 parts 1 to 8 [8]-[15] and EN 300 444 [2],
ETS 300 824 [5] or ETS 300 434-2 [1]), unless specified in the present document.
When one mode is entered the DMT shall operate like a single mode terminal that is switched on. When one mode is left
the DMT shall operate like a single mode terminal that is switched off (except for what is specified in subclause 5.2.2.4).
When the DMT switches mode, it shall leave the first before entering the second, and shall operate as two single mode
terminals where the first is switched off before the second is switched on.
In DECT mode it shall be possible to switch to GSM mode to make an emergency call.
Switching between the two modes is done manually by the user or automatically by the terminal. The DMT shall not
switch mode when in active communication. Automatically switching of mode can be based on background scanning or
loss of coverage. In the case the switching of modes is based on background scanning there are requirements to prevent
switching too frequently, see subclause 5.2.2.3 (if the switching is done automatically, the terminal may perform
background scanning and may then change mode as a result of it).
Entry of the Personal Identification Number (PIN) shall be done according to GSM 02.30 (ETS 300 511 [3]) at switch
on of the DMT with a Subscriber Identity Module (SIM) in or at insertion of the SIM when the DMT is switched on. At
the time of entering the PIN the DMT may be in DECT or GSM mode.
NOTE: 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 in
DECT mode.
The DECT part of the DMT shall be based on at least one of the DECT profiles: Generic Access Profile (GAP)
(EN 300 444 [2]); Cordless Terminal Mobility (CTM) Access Profile (CAP) (ETS 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.
5 Provisions for providing continuity of service
5.1 General
A DMT with valid International Mobile Subscriber Identity (IMSI) and/or Access Rights Identity/Portable Access
Rights 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.
If the DMT looses the coverage of the network currently in use, an established communication will be terminated. If the
user then wants to continue, another mode and/or network providing service has to be selected and a new
communication has to be established.
NOTE 2: Seamless handover of an active communication between GSM and DECT modes is thus not supported.

9 EN 301 242 V1.1.3 (1998-06)
5.2 Mode selection
5.2.1 General requirements
The DMT shall support at least the following two mechanisms of mode selection:
- manual mode selection;
- automatic mode selection.
NOTE: Network controlled mode selection is not considered in the present document.
The user shall be given the opportunity to change mode selection mechanism at any time when the DMT is not in active
communication.
When the automatic mode selection mechanism is activated, either GSM or DECT shall be considered as the preferred
mode according to the users preference. The user shall be given the opportunity to change the preferred mode at any
time when the DMT is not in active communication.
When using the manual mode selection the user shall be given the opportunity to change the chosen mode at any time
except when in active communication. Background scanning may be implemented in the manual mode selection
mechanism, e.g. to give notification to the user on the availability of other networks.
The DMT shall give an indication to the user of the mode currently in use.
