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).

NOTE: The call barring program "incoming calls when roaming outside the home PLMN country" (clause 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.
