Foreword
This European Telecommunication Standard (ETS) has been produced by the Special Mobile Group
(SMG) of the European Telecommunications Standards Institute (ETSI).
This ETS defines a recommended set of supplementary services to the Teleservices and Bearer services
which will be supported within the digital cellular telecommunications system (Phase 2/Phase 2+).
This ETS is a GSM Technical Specification version 5 and is part of the 1996 release of the GSM
Technical Specifications, which incorporate GSM Phase 2+ enhancements/features to the version 4
GSM Technical Specifications.
The contents of this ETS is subject to continuing work within SMG and may change following formal SMG
approval. Should SMG modify the contents of this ETS, it will be resubmitted for OAP by ETSI with an
identifying change of release date and an increase in version number as follows:
Version 5.x.y
where:
y the third digit is incremented when editorial only changes have been incorporated in the
specification;
x the second digit is incremented for all other types of changes, i.e. technical enhancements,
corrections, updates, etc.
The specification from which this ETS has been derived was originally based on CEPT documentation,
hence the presentation of this ETS may not be entirely in accordance with the ETSI rules.

1 Scope
The purpose of this European Telecommunication Standard (ETS) is to define a recommended set of
supplementary services to the Teleservices and Bearer services which will be supported by a GSM PLMN
in connection with other networks as a basis for the definition of the network capabilities required.
The descriptions of the different supplementary services are contained in the GSM 02.80 series.
Supplementary services not covered in GSM 02.04 or GSM 02.80 series cannot be introduced unilaterally
in any GSM PLMN if they require modification of the GSM signalling Specifications.
Technical realization of supplementary services is described in GSM 03.11 and 04.10.
1.1 Normative references
This ETS incorporates by dated and undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications
apply to this ETS only when incorporated in it by amendment or revision. For undated references, the

2 General
2.1 Supplementary service
A supplementary service modifies or supplements a basic Telecommunication service.
NOTE 1: Provision of supplementary services by PLMN operators may be considered as
essential (E) or additional (A). E-supplementary services shall be made available in all
GSM PLMNs. A-supplementary services may be offered by GSM PLMN operators for
national service and can be made available internationally on the basis of bilateral
agreement.
NOTE 2: Offered supplementary services may be used by subscribers/users at their discretion.
2.2 Concepts associated with supplementary services
For the purpose of this ETS the following terms are defined:
Provision
An action to make a service available to a subscriber. The provision may be:
- general: where the service is made available to all subscribers (subject to
compatibility restrictions enforced) without prior arrangements being made with the
service provider.
- pre-arranged: where the service is made available to an individual subscriber only after
the necessary arrangements have been made with the service provider.
Withdrawal
An action taken by the service provider to remove an available service from a subscriber's access.
The withdrawal may be:
- general: where the service is removed from all subscribers provided with the
service.
- specific: where the service is removed on an individual basis from subscribers
provided with the service.
Registration
The programming by the service provider or subscriber of information to enable subsequent
operation of a service. The programming action involves input of specific supplementary
information. For certain services the registration procedure may cause activation whilst for others
the service may already be in the action phase.

SIST ETS 300 918 E2:2005
Page 9
ETS 300 918 (GSM 02.04 version 5.5.1): August 1997
Erasure
The deletion by the service provider, the subscriber or the system of information stored against a
particular service by a previous registration(s).
Activation
An action taken by either the service provider, the subscriber or the system to enable a process to
run as and when required by the service concerned, resulting in the active phase. Some services
can be either "operative" or "quiescent" (not operative) during the active phase according to whether
or not the system would be able to invoke or use the service.
Deactivation
An action taken by either the service provider, the subscriber or the system to terminate the process
started at the activation.
Invocation
An action to invoke the service required, taken by the subscriber (e.g. pressing a specific button) or
automatically by the network or terminal as a result of a particular condition (e.g. calling number
identification for each incoming call).
Normal operation with successful outcome
Description of the normal operation of the service, the normal served subscriber's actions and the
system response. Decision points, timing and call progress signals would be some of the aspects
defined for the service if they can be perceived by the subscriber.
Interrogation
The request by the subscriber to the PLMN to provide information about a specific supplementary
service. This information can be requested by a:
- status check;
The following values can be returned by the PLMN:
- not supported
- active and operative
- active and quiescent
- not active
Not all values are applicable to all supplementary services.
- data check;
This interrogation function compares the data input by the subscriber during an interrogation
procedure with the information stored in the PLMN. The PLMN signals an appropriate
indication (e.g. "check is positive" or "check is negative").
- data request;
This interrogation function enables the subscriber to obtain confirmation of her input data.
The PLMN signals an appropriate indication (e.g. "the forwarded-to number is etc."). The
response to a data request may comprise the status of the service (e.g. not active).
Exceptional operation or unsuccessful outcome
Abnormal situations not described in "normal operation with successful outcome". Procedures on
time-out, unexpected signalling response and other such events would be defined.
Interaction with other supplementary services
When more than one supplementary service is active, new logical situations, decisions, priorities,
etc., may arise. This section would identify and define the resolution of such situations as they affect
subscriber perception of the service. Special procedures may therefore be required, e.g. to allow,
where possible, the simultaneous use of different supplementary services by one mobile subscriber.
Interworking considerations
Identification of subscriber perceptions when a call exits from an ISDN/PLMN to another network or
enters an ISDN/PLMN from another network (e.g. PSTN).

Unstructured SS Operations
These operations are characterized by:
- In the mobile to network direction the transparent transport of MMI strings entered by the
user to the network.
- In the network to mobile direction the transparent transport of text strings that are displayed
by the mobile for user information.
These operations provide capabilities that can either be used as part of operator specified services,
or to facilitate the early introduction of GSM specified services.
NOTE: This Specification does not distinguish between subscriber, user and customer, since
all three do not fully cover the textual needs. Generally the term "subscriber" is used,
even if this person is not having the subscription.
3 Categories and framework of supplementary services
3.1 Framework for the description of supplementary services
GSM 02.01 describes the principles of the Telecommunication services provided in a GSM PLMN. It also
defines the concepts of Telecommunication services and describes their characterization by appropriate
attributes. Bearer services and Teleservices, which are offered by a GSM PLMN in connection with other
networks, are respectively defined in GSM 02.02 and 02.03. Besides these basic Telecommunication
services, their enhancement or modification by supplementary services need also to be offered.
A supplementary service modifies or enhances a basic Telecommunication service and, hence, cannot be
offered to a subscriber on a stand alone basis. It must be offered together with or in association with a
basic Telecommunication service. The same supplementary service may be offered with a number of
different Telecommunication services. For applicability of a Supplementary Service to a
Telecommunication service refer to annex A.
Table 3.1/GSM 02.04 (identical to table 1/GSM 02.01 and to table 1 of CCITT Recommendation I.210)
illustrates the description of Telecommunication services.
Table 3.1/GSM 02.04: Categorisation of Telecommunication services
TELECOMMUNICATION SERVICE
BEARER SERVICE TELESERVICE
Basic Bearer Basic Bearer service + Basic Teleservice Basic Teleservice +
Service supplementary services supplementary service
Provision and withdrawal of a supplementary service, with the exception of Closed User Group, shall apply
to all basic services the subscriber subscribes to.
Registration, erasure, activation and deactivation of a supplementary service shall apply to one or more
group of basic services. The groups of basic services are defined to avoid handling of many basic service
codes.
An operation is effective on the basic services, within the basic service group, which have been
provisioned and for which the supplementary service is applicable. The fact that a basic service is
provisioned but is not supplied by the network shall not lead to reject the request. The request shall be
accepted since there is one basic service within the group(s) which is provisioned and for which the
supplementary service is applicable. For applicability of a Supplementary Service to a basic service or
service group refer to annex A.
Note that Supplementary Service operations on "alternate" and "followed by" Bearer Services (BS61 and
BS81) are managed on the basis of the Bearer Service BS2x or BS3x corresponding to the data part of
the "alternate" and "followed by" Bearer Services. This means that subscribers with a subscription to basic
services BS61 or BS81 can perform call independent supplementary service operations against the

groups "all data circuit asynchronous" and "all data circuit synchronous" regardless of whether or not they
have a subscription to any of the basic services in the set BS2x or BS3x.
This is also required for the invocation of a supplementary service related to the "alternate" and "followed
by" Bearer Services.
The basic service groups are defined in table 3.2/GSM 02.04.

3.2 Categories of supplementary services
Below follows a list of the possible categories of supplementary services related to provision, withdrawal,
registration, erasure, activation, deactivation, invocation and interrogation.

---------------------- Page: 13 ----------------------

SIST ETS 300 918 E2:2005
Page 12
ETS 300 918 (GSM 02.04 version 5.5.1): August 1997
Provision of a supplementary service can be made on a subscription basis, i.e. after pre-arrangement with
the service provider, or the supplementary service can be made generally available to all mobile
subscribers having access to GSM PLMNs.
Withdrawal of a supplementary service can be as a result of a subscriber's request or for administrative
reasons. Both withdrawal actions are performed by the service provider.
Registration of a supplementary service is only applicable to those supplementary services in which
specific data is required to enable subsequent operation of the service. This registration can be the result
of provision or it can be a subscriber controlled procedure. Registration of a supplementary service may
mean simultaneous activation of that service.
Erasure of a supplementary service is only applicable to those supplementary services for which
registration is necessary. It can be the result of withdrawal, it can be the result of a new registration
overruling, and thus effectively erasing the previous registration, or it can be a subscriber controlled
procedure. Erasure of a Supplementary Service may mean simultaneous deactivation of that service.
Activation of a supplementary service can be the result of provision. In some cases the supplementary
service is only activated if the conditions in the subscription options are met. A supplementary service can
also be activated by means of a procedure controlled either by the mobile subscriber or the service
provider. Some supplementary services may also be activated as a result of registration.
Deactivation of a supplementary service can be the result of withdrawal or erasure of the service. In some
cases the supplementary service is deactivated if the conditions in the subscription options are not met. A
supplementary service can also be deactivated by means of a procedure controlled either by the mobile
subscriber or the service provider. A supplementary service can be automatically deactivated at the end of
a call if the supplementary service was specifically activated for that call. Finally, a supplementary service
may be automatically deactivated by the network as a consequence of activation of another
supplementary service if it conflicts with the other activated supplementary service.
Invocation of a supplementary service can take place by means of a subscriber controlled procedure or
automatically by the network as a result of a particular condition.
Interrogation of a supplementary service is only applicable for a few supplementary services for which it is
useful to get information from the network about the status or relevant data concerning the supplementary
service.
4 Supported supplementary services
Table 4.1/GSM 02.04 gives a list of possible supplementary services implemented in the GSM PLMN, the
definitions of which are given in the GSM 02.80 and 02.90 series of specifications.
For the recommended provision of services classified as Additional or Essential (A, E1, E2, or E3), see
relevant GSM/PCN MoU documents.
The availability of the detailed technical specifications of the Supplementary Services listed in GSM 02.04,
i.e. the possibility of implementing them, is to be found in the GSM Action Plan/Release List.
NOTE: All supplementary services in this table are implemented in the PLMN. Subscribers can
use these supplementary services for calls within the PLMN, but also in interworking
situations with the PSTN (if supported) and the ISDN. In interworking situations with
CSPDN and PSPDN these supplementary services can only be used during call set up
(e.g. call forwarding services). When a call is established between an MS and a PDN,
the MS acts as a data network terminal and can consequently only use the
supplementary services that are supported by the relevant PDN. The PDN
supplementary services are not described in this Specification; they can be found in
the relevant PDN Specifications. However, the interworking situations with PDNs still
require further study.
It has been identified as a requirement that the man-machine interface in GSM PLMNs regarding
supplementary services should be compatible as much as possible with the man-machine interface in the
fixed networks as defined in CEPT groups, e.g. the same use of keypad information or function keys.
