0i  Introductionp. 5

The present document includes references to features which are not part of the Phase 2+ Release 96 of the GSM Technical specifications. All subclauses which were changed as a result of these features contain a marker (see table below) relevant to the particular feature. GSM 10.01 defines the correspondence between these features and GSM yearly releases.
The following table lists all features that were introduced after Release 96.

0  Scopep. 6

This Technical Specification (TS) specifies the procedures used at the radio interface (reference point Um as defined in TS 24.002) for normal operation, registration, erasure, activation, deactivation, invocation and interrogation of call barring supplementary services. Provision and withdrawal of supplementary services is an administrative matter between the mobile subscriber and the service provider and cause no signalling on the radio interface.
In TS 24.010 the general aspects of the specification of supplementary services at the layer 3 radio interface are given.
3GPP TS 24.080 specifies the formats and coding for the supplementary services.
Definitions and descriptions of supplementary services are given in TS 22.004, GSM 02.8x and GSM 02.9x-series.
Technical realization of supplementary services is described in TS 23.011, GSM 03.8x and GSM 03.9x-series.
The procedures for Call Control, Mobility Management and Radio Resource management at the layer 3 radio interface are defined in TS 24.007 and TS 24.008.
The following supplementary services belong to the call restriction supplementary services and are described in this specification:
  • Barring of outgoing calls (clause 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 (clause 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);
  • Anonymous Call Rejection (ACR) (Barring program 3).

The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
  • References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific.
  • For a specific reference, subsequent revisions do not apply.
  • For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.

0.2  Abbreviationsp. 7

Abbreviations used in this specification are listed in TR 21.905.

0.3  Cross phase compatibilityp. 7

For the following supplementary services, a number of changes exist between this specification and the protocol version 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 subclause 1.7 and subclause 2.7 defines the additional requirements for when one or more network entities or the MS complies with the protocol version 1 specifications for the supplementary service procedures.
