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):
