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 the stage 2 of the Call Barring (CB) supplementary services for the European digital
cellular telecommunications system (Phase 2).
This ETS corresponds to GSM Technical Specification (GSM-TS) GSM 03.88 version 4.6.1.
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).
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 current GSM ETSs.

0 General
0.1 Overview
This specification gives the stage 2 description of the call barring services.
The possibility for a mobile subscriber to have certain categories of calls barred originated from or
terminated at his access:
Barring of outgoing calls (section 1):
- Barring of all outgoing calls (BAOC) (Barring program 1);
- Barring of outgoing international calls (BOIC) (Barring program 2);
- Barring of outgoing international calls EXCEPT those directed to the home PLMN country
(BOIC-exHC) (Barring program 3).
Barring of incoming calls (section 2):
- Barring of all incoming calls (BAIC) (Barring program 1);
- Barring of incoming calls when roaming outside the home PLMN country
(BIC-Roam) (Barring program 2).
NOTE: The call barring program "incoming calls when roaming outside the home PLMN
country" (section 2) is only relevant if as a general rule the called mobile subscriber
pays the charges for the forwarded part of the call from his home PLMN country to any
other country.
0.2 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.

(Phase 2); "Abbreviations and acronyms".
[2] GSM 02.82 (ETS 300 515): "European digital cellular telecommunications
system (Phase 2); Call Forwarding (CF) supplementary services - Stage 1".
[3] GSM 03.11 (ETS 300 529): "European digital cellular telecommunications
system (Phase 2); Technical realization of supplementary services".
0.3 Definitions and abbreviations
Abbreviations used in this specification are listed in GSM 01.04.
0.4 Cross-Phase compatibility
For the following supplementary services, a number of changes exist between this specification and the
Phase 1 specification:
- Barring of outgoing calls;
- Barring of incoming calls.
The main body of this specification assumes that all network entities comply with this version of the
service. In each case an additional sub-section (sections 1.6 and 2.6) defines the additional requirements
---------------------- Page: 9 ----------------------
SIST ETS 300 548 E1:2003
Page 8
ETS 300 548: March 1995 (GSM 03.88 version 4.6.1)
for when one or more network entities or the MS complies with the Phase 1 specifications for the
supplementary service procedures.
1 Barring of outgoing calls
1.1 Handling of barring of outgoing calls
1.1.1 Registration
If the served mobile subscriber at provision time has selected the subscription option "control of barring
services by subscriber using password", he has to register a password at provision time. Furthermore the
served mobile subscriber can change the password by an appropriate control procedure at any time. The
control procedure consists of three steps: first, the old password has to be provided. Secondly, the new
password has to be given, after which it has to be verified by providing it once more, see TS GSM 03.11.
If the served mobile subscriber at provision time has selected the subscription option "control of barring
services by the service provider" an attempt to register a password will be denied and the served mobile
subscriber should receive a notification.
The subscriber can register a new password, thus causing the previous registration to be overridden, see
TS GSM 03.11.
1.1.2 Activation
1.1.2.1 General
If the served mobile subscriber at provision time has selected the subscription option "control of barring
services by subscriber using password" the supplementary service is activated if the subscriber provides
the following information to the network:
1) password;
2) information as to whether the activation applies to all basic services or a specific basic service
group;
3) selected barring program.
Activation can take place with an appropriate control procedure by the subscriber.
If the served mobile subscriber at provision time has selected the subscription option "control of barring
services by the service provider", the supplementary service cannot be activated by the subscriber. The
activation has to be performed by the service provider. An attempt to activate the service will be denied
and the served mobile subscriber should receive a notification.
If the served mobile subscriber at provision time has selected the subscription option "control of barring
services by subscriber using password", and if a wrong password is entered to activate the service the
supplementary service will not be activated and the served mobile subscriber is notified.
The information flow for activation of barring of outgoing calls is shown in figure 1.4. For more details see
TS GSM 03.11.

1.1.2.2 Interactions between barring of outgoing call programs
In case the served mobile subscriber activates barring of outgoing international calls except those directed
to the home PLMN country and this service is not supported by the PLMN in which the served mobile
subscriber currently roams, the VPLMN will activate barring of outgoing international calls instead. The
SDL diagram in figure 1.1 shows the function to be performed in the VLR in order to deal with this
interaction. This function is performed upon receiving the "insert subscriber data" message from the HLR.
In case the mobile subscriber activates one of the call barring programs and another call barring program
was already activated, this program will be deactivated and the requested call barring program will be
activated. The SDL diagram in figure 1.2 shows the function to be performed in the HLR in order to deal
with this interaction between call barring programs.
1.1.2.3 Interactions with call forwarding supplementary services
For interactions with call forwarding supplementary services see TS GSM 02.82.
The SDL diagram in figure 1.3 shows the function to be performed in the HLR in order to deal with the
interactions with call forwarding supplementary services.

with the addition that a barring supplementary service, i.e. the Outgoing barring service, or All barring
services can be signalled.
The information flow for deactivation of barring of outgoing calls is shown in figure 1.5. For more details

1.3 Information stored in the HLR
For all call barring supplementary services in the HLR must be stored:
- the subscription option "control of barring services" on per subscriber basis.
This subscription option takes one of the following values:
- by subscriber using password;
- by the service provider.
If the subscription option "control of barring services" has been set to "by subscriber using password" for
barring of outgoing calls in the HLR must be stored on per subscriber basis:
- the registration parameter "call barring password"
The password is valid for all basic services to which barring of outgoing calls applies;
- the status parameter "wrong password attempts counter" associated with the password.
Note that the subscription option and the call barring password are parameters which are associated with
all call barring services.
The outgoing calls barring program may have the following logical states (refer to GSM 03.11 for an
explanation of the notation):
