Full Description
ETSI TS 122 088 describes the supplementary services belonging to the group Call Restriction Supplementary Services.The general aspects - including definitions and recommended provision - of the description of the supplementary services are given in 3GPP TS 22.004 [2].
The Call Restriction supplementary services allow the possibility for a mobile subscriber to have barring of certain categories of outgoing or incoming calls at the mobile subscribers access.
The group of Call Restriction Services includes two supplementary services:barring of outgoing calls;barring of incoming calls.By use of subscription options, the mobile subscriber can at provision time select a set of one or more barring programs to determine the categories of calls to be barred. The following categories are defined:all outgoing calls;outgoing international calls;outgoing international calls except those directed to the home PLMN country;all incoming calls;incoming calls when roaming outside the home PLMN country.
NOTE 1: Each category (barring program) is handled as a single supplementary service.
NOTE 2: The call barring program "incoming calls when roaming outside the home PLMN country" 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.
The barring services can be offered to a mobile subscriber with a password option allowing the activation and deactivation by the subscriber. One password per mobile subscriber is supported by the network for all barring services. For the definition of the password, the description of its use and its management, see 3GPP TS 22.004 [2].
