History..........................................................................................................................................................21

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 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+).

The ETS on which this Phase 2+ is based is Phase 2 GSM ETS 300 503 Edition 3 (GSM 02.04

The contents of this ETS is subject to continuing work within TC-SMG and may change following formal

TC-SMG approval. Should TC-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:

y the third digit is incremented when editorial only changes have been incorporated in the

x the second digit is incremented for all other types of changes, i.e. technical enhancements,

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.

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.

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

A supplementary service modifies or supplements a basic Telecommunication service.

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.

These operations provide capabilities that can either be used as part of operator specified services,

do not fully cover the textual needs. Generally the term "subscriber" is used, even if

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

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

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

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

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

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

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

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.

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

(e.g. call forwarding services). When a call is established between an MS and a PDN,

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.

Table 4.1/GSM 02.04 lists the categories for all supported supplementary services. Below the
