5.1 Circuit Oriented Services

As described in the following categories, the Service Provider may at any time activate this feature and this shall terminate any relevant calls in progress, including forwarded calls, and bar future calls covered by the barring category:

Independently, one of:

1.1 Barring outgoing calls;

or: 1.2 Barring outgoing international calls;

or: 1.3 Barring outgoing international calls except those directed to the home PLMN country;

or: 1.4 Barring of outgoing calls when roaming outside the home PLMN country;

or: 1.5 Barring of outgoing inter-zonal calls;

or: 1.6 Barring of outgoing inter-zonal calls except those directed to the home PLMN country;

or: 1.7 Barring of outgoing international calls except those directed to the home PLMN country AND barring of outgoing inter-zonal calls.

And/or one of:

2.1 Barring incoming calls;

or: 2.2 Barring incoming calls when roaming outside the home PLMN country;

or: 2.3 Barring incoming calls when roaming outside the zone of the home PLMN country.

And/or one of:

3.1 Barring of Roaming outside the home PLMN;

or: 3.2 Barring of Roaming outside the home PLMN country.

And/or one or more of:

4.1 Barring of outgoing Premium Rate Calls (Information);

4.2 Barring of outgoing Premium Rate Calls (Entertainment);

4.3 Barring of outgoing Premium Rate Calls (Information) when roaming outside the home PLMN country;

4.4 Barring of outgoing Premium Rate Calls (Entertainment) when roaming outside the home PLMN country.

And/or one or more of:

5.1 When registered in the HPLMN, Operator Specific Barring (Type 1);

or: 5.2 When registered in the HPLMN, Operator Specific Barring (Type 2);

or: 5.3 When registered in the HPLMN, Operator Specific Barring (Type 3);

or: 5.4 When registered in the HPLMN, Operator Specific Barring (Type 4).

And/or

6.1 Barring of Supplementary Services Management, which prevents user control of any supplementary service (registration, erasure, activation, deactivation, user invocation, interrogation, password registration and mobile initiated USSD). However, this does not prevent invocation by other action – e.g. an existing call forwarding or barring state will remain.

And/or one of:

7.1 Barring of registration of any call forwarded-to number;

or: 7.2 Barring of registration of any international call forwarded-to number;

or: 7.3 Barring or registration of any international call forwarded-to number except to a number within the HPLMN country;

or: 7.4 Barring of registration of any inter-zone call forwarded-to number.

Or: 7.5 Barring of registration of any inter-zone call forwarded-to number except to a number within the HPLMN country;

Note: The definition of an international call is based on the equivalent definition of an international call in TS 22.088 [2]. The principles for deciding whether a forwarded-to number is international or inter-zonal are the same as those given in TS 22.082 [4] to determine the interactions between call forwarding and call barring.

And/or one of:

8.1 Barring of invocation of call transfer;

or: 8.2 Barring of invocation of call transfer where at least one of the two calls is a call charged to the served subscriber; i.e. the call is either an outgoing call or an incoming call when the served
subscriber roams outside the HPLMN;

or: 8.3 Barring of invocation of call transfer where at least one of the two calls is a call charged to the served subscriber at international rates, i.e. the call is either an outgoing international call or an incoming call when the served subscriber roams outside the HPLMN country;

or: 8.4 Barring of invocation of call transfer where at least one of the two calls is a call charged to the served subscriber at inter-zonal rates, i.e. the call is either an outgoing inter-zonal call or an incoming call when the served subscriber roams to a VPLMN in a different zone from the HPLMN.

And/or:

9 Barring of invocation of call transfer where both calls are calls charged to the served subscriber, i.e. both calls are either outgoing calls or incoming calls when the served subscriber roams outside the HPLMN;

and/or:

10 Barring of further invocation of call transfer if there is already one ongoing transferred call for the served subscriber in the serving MSC/VLR.

"User invocation", as it relates to ODB, consists of the following action:

– invocation of the call hold supplementary service.

"Zone" is as based on the first digit of their international dialing code as defined in ITU-T Recommendation E.164 [3].

Note: For the purposes of this TS, zone 3 and zone 4 are treated as one zone.

Note: If control of Supplementary Services Management is barred, then the control of call forward will be barred as a consequence, so explicit barring of call forward activation is not necessary.

If a mobile subscriber attempts to use a mobile initiated service which is barred as described above (categories 1, 4, 5, 6, 7, 8, 9, and 10), an appropriate message shall be returned to the Mobile Station or alternatively (categories 1, 4, and 5), if located in the HPLMN, the mobile subscriber can be automatically connected to a destination address determined by the HPLMN operator. It is necessary for the message to indicate that the barring is due to Operator Determined Barring. It is not necessary to indicate the categories which are barred. For ongoing, or transferred calls, that are terminated due to ODB, the network operator may give an appropriate indication to the barred party.

A notification (announcement or ITU-T#7 cause value) may be returned to callers attempting to call a mobile subscriber who is appropriately barred incoming calls. It is not necessary to indicate to the called mobile station that an incoming call has been barred.

Only the HPLMN Operator can activate, change or deactivate application of this network feature.

In order to provide this feature securely when a subscriber roams to another network, the visited network needs to support the feature to ensure that the roaming subscriber cannot use a service which has been barred to him.

5.2 Packet Oriented Services

Packet Oriented Services, particularly data services, are different in nature to Circuit Oriented Services, and therefore have different requirements for Operator Determined Barring.

As described in the following categories, the Service Provider may at any time activate this feature and this shall terminate any relevant services in progress, and bar future requests for service covered by the barring category:

 It shall be possible to bar subscribers completely from the Packet Oriented Services.

 Network shall be able to allow a subscriber to access some specific APNs while barring the subscriber from the other Packet Oriented Services.

 It shall be possible to bar a subscriber from requesting Packet Oriented Services from access points that are within the HPLMN whilst the subscriber is roaming in a VPLMN.

 It shall be possible to bar a subscriber from requesting Packet Oriented Services from access points that are within the roamed to VPLMN.

The term ‘access point’ is used to indicate the GGSN or part of the GGSN that is specified by a particular APN.

5.3 Interworking WLAN

Aspects of ODB related to interworking WLAN are addressed in TS 22.234 [6].

5.4 IMS Oriented Services

5.4.1 IMS Multimedia Telephony Services

As described in the following categories, the Service Provider may at any time activate this feature and this shall terminate any relevant communications in progress, including diverted communications, and bar future communications covered by the barring category:

Independently, one of:

1.1 Barring outgoing communication;

or: 1.2 Barring outgoing international communications;

or: 1.3 Barring outgoing international communications except those directed to the home PLMN country;

or: 1.4 Barring of outgoing communications when roaming outside the home PLMN country;

and/or one of:

2.1 Barring incoming communications;

or: 2.2 Barring incoming communications when roaming outside the home PLMN country;

and/or one of:

3.1 Barring of Roaming outside the home PLMN;

or: 3.2 Barring of Roaming outside the home PLMN country.

and/or one or more of:

4.1 Barring of outgoing Premium Rate Communications (Information) for E.164 international premium numbers and for premium numbers located within the home PLMN;

4.2 Barring of outgoing Premium Rate Communications (Entertainment) for E.164 international premium numbers and for premium numbers located within the home PLMN;

Note 1: outgoing communications to non E.164 international premium numbers located outside the home PLMN are barred at interconnection between networks based on bilateral agreements.

and/or one or more of:

5.1 When registered in the HPLMN, Operator Specific Barring (Type 1);

or: 5.2 When registered in the HPLMN, Operator Specific Barring (Type 2);

or: 5.3 When registered in the HPLMN, Operator Specific Barring (Type 3);

or: 5.4 When registered in the HPLMN, Operator Specific Barring (Type 4).

and/or

6 Barring of Supplementary Services Management, which prevents user control of any supplementary service (registration, erasure, activation, deactivation, user invocation, interrogation and password registration). However, this does not prevent invocation by other action – e.g. an existing communication diversion or barring state will remain.

and/or one of:

7.1 Barring of registration of any communication diverted-to address;

or: 7.2 Barring of registration of any international communication diverted-to address;

or: 7.3 Barring of registration of any international communication diverted-to address except to an address within the HPLMN country;

and/or one of:

8.1 Barring of invocation of communication transfer;

or: 8.2 Barring of invocation of communication transfer where at least one of the two communications is a communication charged to the served subscriber; i.e. the communication is either an outgoing communication or an incoming communication when the served subscriber roams outside the HPLMN;

or: 8.3 Barring of invocation of communication transfer where at least one of the two communications is a communication charged to the served subscriber at international rates, i.e. the communication is either an outgoing international communication or an incoming communication when the served subscriber roams outside the HPLMN country;

and/or:

9 Barring of invocation of communication transfer where both communications are communications charged to the served subscriber, i.e. both communications are either outgoing communications or incoming communications when the served subscriber roams outside the HPLMN;

and/or:

10 Barring of further invocation of communication transfer if there is already one ongoing transferred communication for the served subscriber.

If a mobile subscriber attempts to use a mobile initiated service which is barred as described above (categories 1, 4, 5, 6, 7, 8, 9 and 10), an appropriate message shall be returned to the Mobile Station or alternatively (categories 1,4 and 5), if located in the HPLMN, the mobile subscriber can be automatically connected to a destination address determined by the HPLMN operator. It is necessary for the message to indicate that the barring is due to Operator Determined Barring. It is not necessary to indicate the categories which are barred. For ongoing, or transferred communications, that are terminated due to ODB, the network operator may give an appropriate indication to the barred party.

A notification (announcement or appropriate SIP response) may be returned to callers attempting to communicate with a mobile subscriber who is appropriately barred for incoming communications. No indication is provided to the called mobile station that an incoming communication has been barred.

Only the HPLMN Operator can activate, change or deactivate application of this network feature.
