Digital cellular telecommunications system (Phase 2) (GSM); General on supplementary services (GSM 02.04)

REASON: The CLIR interrogation result informs the user only if the service is provided to her. With the introduction of the second temporary mode, this information is no longer sufficient. The user can no longer derive from the provisioning of the service whether her number is shown to the called user or not. CONSEQUENCE OF NON-ACCEPTANCE: The user gets only information about the provisioning of the service, but no information whether the number will be shown to the called user or not.

Foreword
This European Telecommunication Standard (ETS) has been produced by the Special Mobile Group
(SMG) Technical Committee (TC) of the European Telecommunications Standards Institute (ETSI).
This ETS defines a set of supplementary services to the teleservices and bearer services supported by a
PLMN within the Digital cellular telecommunications system (Phase 2).
This ETS corresponds to GSM technical specification GSM 02.04 version 4.9.0.
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/PNE rules.
Reference is made within this ETS to GSM-TSs (NOTE).
Reference is also made within this ETS to GSM 02.80. series. The specifications in the series can be
identified, with their full title, within the normative reference Clause of this ETS by the first three digits of
their GSM reference number e.g. GSM 02.80 series, refers to GSM 02.81, GSM 02.82 etc.
NOTE: TC-SMG has produced documents which give the technical specifications for the
implementation of the European digital cellular telecommunications system.
Historically, these documents have been identified as GSM Technical Specifications
(GSM-TSs). These TSs may have subsequently become I-ETSs (Phase 1), or ETSs
(Phase 2), whilst others may become ETSI Technical Reports (ETRs). GSM-TSs are,
for editorial reasons, still referred to in GSM ETSs.
Transposition dates
Date of adoption of this ETS: 31 January 1996
Date of latest announcement of this ETS (doa): 30 April 1996
Date of latest publication of new National Standard

1 Introduction
1.1 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 specifications 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 Specifications GSM 03.11 and 04.10.
1.2 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
latest edition of the publication referred to applies.

1.3 Definitions and abbreviations
Abbreviations and acronyms used in this specification are listed in GSM 01.04.
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 Specification 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.
Erasure
The deletion by the service provider, the subscriber or the system of information stored against a
particular service by a previous registration(s).

SIST ETS 300 503 E2:2003
Page 9
ETS 300 503: January 1996 (GSM 02.04 version 4.9.0)
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 characterised 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.

ETS 300 503: January 1996 (GSM 02.04 version 4.9.0)
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 1: 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.
NOTE 2: The terms "she" and "her" are used as abbreviation of "she/he" and "her/his, her/him"
respectively.
3 Categories and framework of supplementary services
3.1 Framework for the description of supplementary services
Specification 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 Specification 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.
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.
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.
