1  ScopeWord‑p. 6

The present document 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 (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).

3  AbbreviationsWord‑p. 7

For the purposes of the present document, the abbreviations given in TR 21.905 apply.

4  Cross-Phase compatibility

For the following supplementary services, a number of changes exist between the present document and the Phase 1 specification:
  • Barring of outgoing calls;
  • Barring of incoming calls.
The main body of the present document assumes that all network entities comply with this version of the service. In each case an additional subclause (subclauses 6.6 and 7.6) defines the additional requirements for when one or more network entities or the MS complies with the Phase 1 specifications for the supplementary service procedures.

5  Data stored in the HLR for all call barring services

The following data are stored in the HLR in common for all call barring services other than ACR:
  • The "notification to CSE flag". This flag applies for all call barring services. When the data for any Call Barring are changed, the HLR checks this flag. If the flag is set, the change is reported to the gsmSCF(s) defined by the gsmSCF address list. See TS 23.078.
  • The "gsmSCF address list", which is a list of gsmSCF addresses to which Notification on Change of Subscriber Data is to be sent. This list applies to all call barring services. See TS 23.078.
