The network feature Operator Determined Barring (ODB) as specified TS 22.041
and in this specification allows a network operator or service provider to regulate access to IM CN subsystem services, by the barring of certain categories of incoming or outgoing communications, the barring of certain categories of roaming and the barring of certain categories of supplementary services configuration and invocation. When barring of an incoming or outgoing category of communications is configured all in progress communications belonging to that category are released.
The SIP related procedures for support of ODB of Communication Barring are realized in an Application Server (AS) as defined in TS 24.229
, which depending on the use case, is to be provided on the originating side or the terminating side.
The SIP related procedures for support of ODB of the SIP based configuration of a supplementary service, as defined in TS 24.238
, are realized by the AS which provides the function of SIP based configuration for that supplementary service.
The XCAP related procedures for support of ODB of the XCAP based configuration of a supplementary service, as defined in TS 24.623
, are realized by the AS which provides the function of XCAP based configuration for that supplementary service.
ODB based barring is applied to a subscription by administrative action in the HSS. In order to get the information about the ODB settings for a subscriber an AS can subscribe to notification on such changes via Sh interface as specified in TS 29.329
. The HSS contains the ODB categories that apply to the subscriber. The URIs for premium numbers for entertainment, the URIs for premium numbers for information and the conditions for operator specific categories are locally configured in the AS providing the ODB services. It shall be possible for the operator to use patterns and regular expression to configure the URIs for premium numbers in the AS.
ODB categories cannot be configured by the user.
