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.
