0.2 Abbreviations
Abbreviations used in this ETS are listed in GSM 01.04 [1].
0.3 Definitions
Directory Number: a string consisting of one or more of the characters from the set {0, 1, 2, 3, 4, 5, 6, 7,
8, 9, *, #, a, b, c} associated with a nature of address indicator and number plan indicator. When using the
public MMI for the control of supplementary services however, * and # cannot be part of any SC or SI field.
NOTE 1: No such restriction on the SC and SI fields exists when using other (e.g. menu-driven)
MMI for the control of supplementary services.
NOTE 2: When using the public MMI, certain limitations on the use of one and two digit directory
numbers may apply. The use of other MMI can remove these restrictions.
NOTE 3: This definition is not intended to require the support of all these characters in the MMI
itself.
1 General
1.1 Basic philosophy
The basic idea behind this ETS is that it should give a minimum level of requirements, with emphasis on
items which are seen as important from a pan-European usage point of view. This means, that the
requirements are mainly dealing with standardized control procedures of access to services i.e. call
establishment, invocation of supplementary services and so on. This also includes standardized network
information to the users such as tones and announcements.
Page 9
ETS 300 907 (GSM 02.30 version 5.7.1 Release 1996): August 1999
The requirements on the physical layout of input and output features are kept to a minimum to allow for
differentiated types of MSs and to ease the introduction of future developments in the area of MMI. The
standardized control procedures describe the sequence of real actions to be taken by the users. However,
since the requirements on the physical input features are minimal the control procedures may differ
between MSs depending on the solution of the manufacturers. The "bridge" between these requirements
is however that the same logical actions have to be taken by the user. That is, the user has to provide the
same information for the call control and signalling no matter what the method is. This is also valid if an
automatic device is used for carrying out the same actions. The logical procedures are therefore defined
and standardized in this specification.
The drawback of this approach is that the users of GSM Mobile Stations may face a lot of different types
of physical MMI which they have to learn. However, to deal with this problem the specification gives a
definition of a basic public MMI. The basic public MMI allows non-experienced, casual users to make and
receive a telephony call. This definition is directed to manufacturers of public mobile telephones.
Optionally, the user may set the ME to disable some or all of the MMI functions defined in this
specification. This setting shall only apply when the same SIM is in use (see GSM 02.17 [5] for security
policy), otherwise the ME shall enable the standard MMI.
1.2 Structure of the specification
The ETS is divided into sections describing respectively the control procedures, the input features and the
output features. The final section defines the basic public MMI. For a lot of items for which no particular
MMI specification is necessary there is a reference to the specifications where the basic requirements are
to be found (i.e. MS features specified in GSM 02.07 [3] and language of announcements specified in
GSM 02.40 [7]).
2 Physical user input features
2.1 General
This section gives the requirements or guidelines for the MMI of the input related MS features. Basic
requirements on these features are given in GSM 02.07 [3] and GSM 02.40 [7].
2.2 MMI related to MS access
No requirements additional to those in other GSM specifications (Reference GSM 02.17 [5], 11.10 [20]).
2.3 MMI related to MS features
The three first issues are covered in GSM 02.07 [3]:
* Country / PLMN selection:
The method is manufacturer optional.
* International Access Function ("+" key):
and
* Keypad:
The physical means of entering the characters 0-9, +, * and # (i.e. the SELECT function) may be
keypad, voice input device, DTE or other, but there must be means to enter this information.
The relationship on the keypad between the numbers and letters (where used) is important when
mnemonic dialling may be used. The following relationship is therefore preferred though optional.
1 6 MNO
2 ABC 7 PQRS
3 DEF 8 TUV
4 GHI 9 WXYZ
5 JKL 0
See also subclause 5.2.1.
Page 10
ETS 300 907 (GSM 02.30 version 5.7.1 Release 1996): August 1999
* ACCEPT, SEND and END functions:
The physical means to perform these functions may be keypad, voice input device, DTE or other,
but there must be means to perform these functions. ACCEPT and SEND may use the same
means.
* Setting of called Number Fields (Type of Number), use of the "+" key function:
Users may enter a called number in two formats, called here International or Open. The Type of
Number (TON) may be set to other values if required, but the procedure for this is not defined here.
"International format":
This is entered by starting with a "+" followed by country code, even for national calls. This method
is preferred for roaming and international calls, and highly desirable for storage of short codes or for
call-forwarding.
This sets the TON to "International" - see GSM 04.08 [17] table 10.50.
"Open format":
This is when the "+" is not entered, and the number is entered in the normal way for that network.
The number may require a prefix or escape code as normal, for example for entering the
international access code or national access code (often "0").
This sets the TON to "Unknown" - see GSM 04.08 [17] table 10.50. (This is not the "National" case,
which does not permit prefix or escape digits).
Care should be taken with this format, since the dialled number will only be correct in a given
network, and may be wrong when roaming. Caution must be applied when using stored numbers or
call-forwarding.
* Setting of Called Number Fields (Number Plan Indicator):
The default Number Plan Identification (NPI) shall be CCITT E.164 [22] if all the digits are in the
range 0-9 and the NPI shall be "unknown" if other number information is included. However, if the
user selects (or has selected) a particular NPI (procedure not defined) then that NPI shall be used.
* Entry of Bearer Capability Information Elements (BCIE):
This is required in order to indicate information such as whether it is a voice or data call, facsimile,
synchronous or asynchronous etc. The method for entering this information is of mobile
manufacturer's option. For those Mobile Stations offering only telephony (and emergency calls), the
default BCIE shall be for telephony (or emergency call). For Mobile Stations supporting non-voice
services, there shall be means to set the BCIE required, by reading the appropriate field in the SIM
and possibly otherwise. This field may be associated with or independent of the called number.
2.4 MMI related to user information
These issues are covered in GSM 02.40 [7]:
* Selection of language of announcements:
No additional requirements are defined in this specification.
2.5 Other input features
No requirements additional to those in other GSM specifications (Reference GSM 03.14 [14] 11.10 [20]).

3 Indications and output features
3.1 General
This section gives the requirements and guidelines of the MMI aspects of the outputs such as displayed
information, indications and tones. Basic requirements on these features are given in GSM 02.07 [3] and
GSM 02.40 [7].
3.2 MMI related to MS access
No requirements additional to those in other GSM specifications (ref. GSM 03.12 [13], GSM 04.08 [16],
GSM 05.08 [18]).
3.3 MMI related to MS features
Country/PLMN Indication:
* The country/PLMN Indication (see GSM 02.07 [3] for definition) should be displayed as such that
the user can uniquely identify the country and PLMN e.g. by alpha or numeric means or other.
These issues are covered in GSM 02.07 [3] . No additional requirements are defined in this specification:
* Indication of Call Progress Signals.
* Display of Called Number.
* Short Message.
* Call Charge Units Meter.
3.4 MMI related to user information
These issues are covered in GSM 02.40 [7]. No additional requirements are defined in this specification:
* Selection of language of announcements;
* Supervisory tones.
3.5 Other output features
No requirements additional to those in other GSM specifications (ref. GSM 03.01 [11], 03.09 [12],
03.12 [13], 04.08 [16] and 05.08 [18]).
4 Procedures
4.1 General
This section defines the MMI of the service access procedures, and supplementary service control
procedures. These procedures are defined as logical procedures and in general no mandatory methods
are specified. In order to make the descriptions continuous and clear requirements in GSM 02.07 [3],
02.11 [4], 02.17 [5] and 02.40 [7] have been included or are referenced. The mapping between the MMI
procedures and the call control entity is specified in GSM 04.08 [16].
4.2 MS access
The MS access procedure is comprised of the initial actions the user has to take before calls can be
established or received. This procedure includes e.g. insertion of subscriber-card and entering the PIN-
code.
As there exist different types of MS and as requirements in other GSM specifications allow different
options the MS access procedure may differ between Mobile Stations. The method for describing the MS
access procedures is by using a Mealy-graph, see annex A.
Page 12
ETS 300 907 (GSM 02.30 version 5.7.1 Release 1996): August 1999
The graph shows the MS access for simple MS e.g. hand-held and they may be different for more
complex stations. It should also be noted that the exact sequences of events are not described, these may
be chosen by the manufacturers. Nevertheless, the related requirements in the other GSM specifications
referenced in section 4.1 are applicable.
4.3 Definition of functions
The following functions are applicable and mandatory for the logical procedures for Mobile originated and
terminated calls and for the control of Supplementary Services:
ACCEPT: Acceptance of a mobile terminated call.
SELECT: Entry of information.
SEND: Transmission of the entered information to the network.
INDICATION: Requirements in GSM 02.40 [7] are applicable. Other indications may be given
in addition throughout the procedure.
END: Termination of or disconnection from the call. The execution of the END-function
may be caused by either party involved in the call by e.g. termination, loss of
coverage, invalidation of payment.
4.4 Call Control
4.4.1 General
Voice calls to and from a Mobile Station shall be controlled in accordance with the procedures described
below. "Data calls" are expected to be controlled in a similar way but are not here specified.
4.4.2 Voice calls
The voice call is either a normal telephony call or an emergency call.
4.4.2.1 Mobile originated calls
The following sequence of functions shall be used:
SELECT: Entry of called address information.
SEND: Transmission of the called address.
INDICATION: See section 4.3.
END: Termination of the call.
4.4.2.2 Emergency calls
With Mobile Stations supporting Telephony, it shall be possible to place an emergency call by entering 112
followed by SEND in the manner specified in section 4.4.2.1. It may also be possible for a user to enter a
preferred emergency MMI code of up to six digits (such as 999) followed by SEND to invoke an
emergency call. In this latter case, the preferred code shall be stored in the SIM and the ME recognizes
any dialled instance of this code to set up the emergency call. Additional means to place such a call are
also allowed, e.g. provision of a dedicated button.
The MS must support the initiation of an emergency call to "112" without a SIM present in the MS,
regardless of the call being accepted or not by the network (national option to require IMSI).
Page 13
ETS 300 907 (GSM 02.30 version 5.7.1 Release 1996): August 1999
NOTE: In addition to the above procedure, calls to national emergency services may be made
in the way standard for the country of the serving PLMN. However, with the exception
of code "112", these are not treated within the PLMN as "Teleservice Emergency call"
unless the ME recognizes the code as an emergency code as described above, and
would require a valid IMSI.
4.4.2.3 Mobile terminated calls
The following sequence of functions shall be used:
INDICATION: Alert to the user that she is being called.
ACCEPT: Acceptance of the incoming call by the user.
INDICATION: See section 4.3.
END: Termination of the call.
User Determined User Busy (UDUB): If, on being alerted by an incoming call, the called user
enters "0 SEND", this shall set UDUB for that call, which
shall either invoke call forwarding on busy, if active and
operative, or else present BUSY to the calling party.
4.5 Supplementary Services Control
4.5.1 General
The supplementary services shall be controlled in accordance with the procedures described below. All
Mobile Stations with MMI shall be able to be controlled in this way, to minimize the confusion of users
using different types of Mobile Station (quite likely, due to the use of the SIM IC card) and to permit the
introduction by a PLMN operator of new supplementary services, not defined at the time of the design of a
Mobile Station. These procedures are based on those recommended by CEPT/SF and CCITT
Recommendation E.131.
The specified MMI shall be supported by the L3 signalling between the MS and the MSC, see
GSM 04.80 [17].
In addition to these specified MMI procedures the MS may be equipped with additional enhanced MMI
procedures (e.g. dedicated keys, menu procedures.), left to the discretion of the manufacturer. These
procedures shall also be converted in accordance with GSM 04.80 [17].
4.5.2 Structure of the MMI
The following sequence of functions shall be used for the control of Supplementary Services:
SELECT: Entry of the procedure information (may be a digit or a sequence of characters).
SEND: Transmission of the information to the network.
INDICATION: See section 4.3.
The MS shall support the MMI procedure specified as:
Activation : *SC*SI#
Deactivation : #SC*SI#
Interrogation : *#SC*SI#
Registration : *SC*SI# and **SC*SI#
Erasure : ##SC*SI#
This structure consists of the following parts:
- Service Code, SC( (2 or 3 digits);
- Supplementary Information, SI (variable length).
Page 14
ETS 300 907 (GSM 02.30 version 5.7.1 Release 1996): August 1999
The procedure always starts with *, #, **, ## or *# and is finished by #. Each part within the procedure is
separated by *.
The service code uniquely specifies the Supplementary Service, either as a defined GSM Supplementary
Service or as a spare service code. All spare service codes shall be reserved for future use.
The MS shall determine from the context whether, an entry of a single *, activation or registration was
intended.
For example, a call forwarding request with a single * would be interpreted as registration if containing a
forwarded-to number, or an activation if not.
The supplementary information (SI) may comprise e.g. a PIN code or Directory Number. Where a
particular service request does not require any SI, "*SI" is not entered, e.g. Activation becomes
*SC#SEND. Where further supplementary information is required this is again entered as *SI, e.g.
*SC*SIA*SIB#SEND. SIB may be used to specify the tele or bearer service expressed as a Basic Service
Group to which this supplementary service request applies, SIC may be used to specify the value of the
"No Reply Condition Timer".
Use of SIA, SIB, SIC for a particular procedure is optional. The procedure to be adopted where these are
not all used is as follows:
*SI# shall be entered in any of the following formats:
* SIA * SIB * SIC #
* SIA * SIB #
* SIA * * SIC #
* SIA #
* * SIb * SIC #
* * SIB #
* * * SIC #
#
The denotation of the Supplementary Information and the order of entry are specified in annex B.
Supplementary Information Codes for the Teleservices and Bearer Services are given in annex C.
The following procedures shall be used for application of supplementary services to the call set-up
procedure:
*SCn*SI#DN SEND;
where SC is the service code defined in annex B and *SI is an optional field which may be applicable to
service SC. The "n" is a single digit used to indicate the numbering plan, profile, priority, etc. according to
the service being applied. For simplicity of presentation, the leading * is shown on the assumption that the
action is to activate (switch on) the required service. However, for a deactivation (or switch off), this would
become:
#SCn*SI#DN SEND;
It is assumed that the *# (interrogation) will not apply to call set-up.
Where more than one supplementary service is applicable to the call set-up, these shall be concatenated
with any applicable supplementary information immediately following the applicable service code.
For example, if SCn and SI refer to one applicable supplementary service and scn and si to another, then
the generic procedure becomes:
*SCn*SI#scn*si#DN SEND.
NOTE: The order of entry of SC and sc is a user option, provided that any supplementary
information follows immediately after the relevant SC.

ETS 300 907 (GSM 02.30 version 5.7.1 Release 1996): August 1999
Where SI is not applicable according to the definition of the supplementary service, then *SI is omitted.
Where its use is optional, but not selected for a particular call set-up, it may be omitted or entered as an
extra * if this is necessary to avoid ambiguity of interpretation.
NOTE: By using the # as a separator, most cases are expected to be unambiguous.
4.5.3 Handling of supplementary services
4.5.3.1 Handling of defined GSM supplementary services
The MMI procedure for the defined GSM Supplementary Services shall be converted to the mobile radio
interface Layer 3, as specified in GSM 04.80 [17]. An appropriate message should be given/displayed to
the user in accordance with the "return result/error" from the network.
The service codes for the defined GSM Supplementary Services are given in annex B.
4.5.3.2 Handling of not-implemented supplementary services
The MS shall act in accordance with figure 4.5.3.2 when digits are entered to the MS to determine whether
to interpret these as call set-up requests or supplementary service control procedures etc. This may
involve a mechanism, referred to as Unstructured SS Data, which allows the support of GSM SS services
which are not implemented by means of the GSM specified functional signalling. See also
GSM 02.90 [10].

Figure 4.5.3.2
The following definitions are applicable to the interpretation of figure 4.5.3.2:
1) In a call:
A MS is "in a call" from the time that signalling related to the establishment or attempted
establishment of a MO or MT call commences and before the call or call attempt ends, and (if
applicable) the ME has stopped generating tones related to this call to the user.
Page 17
ETS 300 907 (GSM 02.30 version 5.7.1 Release 1996): August 1999
2) MS manufacturer defined procedure:
The term "MS manufacturer defined procedure" shall not include the following two cases:
(i) input which can be interpreted as being of the following form, whether or not in a
call:
CX [string]# followed by SEND;
where
string is any combination of numeric digits, *, #;
and
C comprises 1, 2 or 3 digits from the set (*,#);
and
X comprises 1, 2 or 3 numeric digits or the fourth numeric digit is non-zero;
(ii) input of the following form in a call (as defined above):
"Entry of 1 or 2 characters defined in the GSM 03.38 [15] Default Alphabet followed by
SEND".
3) #-string:
Input of the form.
"Entry of any characters defined in the GSM 03.38 [15] Default Alphabet (up to the maximum
defined in GSM 04.80 [17]), followed by #SEND".
4) Short string:
"Entry of 1 or 2 characters defined in the GSM 03.38 [15] Default Alphabet followed by
SEND".
5) Call setup string:
MMI input in accordance with the call set-up procedures as defined in GSM 04.08 [16] and
terminated by SEND.
If the network has initiated an operation which explicitly (in the signalling) requires a response from the
user, then the user shall be able to enter a response in the form of any string of characters followed by
SEND. The mobile shall also provide an MMI command to terminate the dialogue with a NULL response.
The use of END shall release all calls in progress (see also section 4.5.5.2), terminate any outstanding
unstructured SS operations, and release any connection used for unstructured SS operations.
4.5.4 Registration of new password
The following procedure permits the user to change the password relating to use of Supplementary
Services. The only control procedure supported is Registration of a new password, which replaces any
previous password for the same service. The password may not be Erased or Interrogated.
Procedure:
* 03 * ZZ * OLD_PASSWORD * NEW_PASSWORD * NEW_PASSWORD #
The MS shall also support the alternative procedure:
** 03 * ZZ * OLD_PASSWORD * NEW_PASSWORD * NEW_PASSWORD #
where, for Barring Services, ZZ = 330;
Page 18
ETS 300 907 (GSM 02.30 version 5.7.1 Release 1996): August 1999
for a common password for all appropriate services, delete the ZZ, entering:
* 03 ** OLD_PASSWORD * NEW_PASSWORD * NEW_PASSWORD #
The MS shall also support the alternative procedure:
** 03 ** OLD_PASSWORD * NEW_PASSWORD * NEW_PASSWORD #
the MS will then indicate to the user whether the new password request has been successful or not. If the
new password request is rejected (e.g. due to entry of incorrect old password) the old password remains
unchanged, until it is successfully changed by correctly repeating the procedure. Refer to GSM 02.04 [2]
regarding repeated entry of incorrect password.
NOTE: The procedures shall be followed by SEND as described in section 4.5.2.
4.5.5 Handling of supplementary services within a call
4.5.5.1 Call Deflection, Call Waiting, Call Hold, MultiParty Services, Explicit Call Transfer
and Completion of Calls to Busy Subscriber general principles
During a call, the following general procedures shall be available, where applicable, for the subscriber to
control the operation of
- Call Deflection
- Call Waiting
- Call Hold
- MultiParty Services
- Explicit Call Transfer
- $(CCBS)$: Completion of Calls to Busy Subscriber
including their interactions. It should be noted that not all control procedures described in GSM 02.72,
02.83, 02.84, 02.91, and 02.93 are specified in this section.
Procedures:
Entering 0 followed by SEND - Releases all held calls or sets User Determined User Busy
(UDUB) for a waiting call.
Entering 1 followed by SEND - Releases all active calls (if any exist) and accepts the other
(held or waiting) call.
Entering 1X followed by SEND - Releases a specific active call X.
Entering 2 followed by SEND - Places all active calls (if any exist) on hold and accepts the
other (held or waiting) call.
Entering 2X followed by SEND - Places all active calls on hold except call X with which
communication shall be supported.
Entering 3 followed by SEND - Adds a held call to the conversation.
Entering 4 followed by SEND - Connects the two calls and disconnects the subscriber
from both calls (ECT).
Entering 4 * "Directory Number" - Redirect an incoming or a waiting call to the specified
followed by SEND directory number.
Entering 5 followed by SEND - $(CCBS)$: Activates the Completion of Calls to Busy
Subscriber Request.
Entering "Directory Number" - Places all active calls (if any exist) on hold and sets up a
followed by SEND new call to the specified Directory
Number.
Entering END - Releases the subscriber from all calls (except a possible
waiting call).
