1 Scope
The network feature Operator Determined Barring (ODB) allows a network operator or service provider to regulate
access by subscribers to services (Circuit/Packet Oriented and Interworking WLAN), by the barring of certain
categories of incoming or outgoing calls/ Packet Oriented Services or of roaming. Operator Determined Barring applies
to all bearer services and teleservices except the Emergency Call teleservice and Emergency Bearer Services; the
teleservice Short Message Point-to-Point is therefore subject to Operator Determined Barring in the same way as
circuit-switched calls.
The application of specific categories of Operator Determined Barring to a subscription is controlled by the network
operator or service provider, using administrative interaction at the HLR; this interface is not standardised.
1.1 Normative references

2 Method of realisation
The entities which control the application of Operator Determined Barring (ODB), and the methods used, are described
in this clause. Two cases are considered for each type of barring: the effect of administrative action in the HLR to
modify the application of the category to a particular subscription, and the effect of the category on the handling of calls
or other traffic involving the subscriber.
2.1 Barring of Outgoing Calls or Mobile Originated Short
Messages
Barring of outgoing calls or mobile originated short messages includes the categories "outgoing calls" and "outgoing
premium rate calls" defined in 3GPP TS 22.041 [2], and the "operator specific barring" category where this is defined
by the PLMN operator to apply to outgoing calls or mobile originated short messages.

3GPP TS 23.015 version 15.1.0 Release 15 7 ETSI TS 123 015 V15.1.0 (2019-03)
2.1.1 Application or Change of Barring in the HLR
If barring of outgoing calls or mobile originated short messages is applied to a subscription (or existing barring of
outgoing calls or mobile originated short messages is modified or removed) by administrative action in the HLR, the
HLR will update the subscription information accordingly, and transfer the updated subscription information to the
VLR and the SGSN using one or more Insert Subscriber Data operations, as shown in figure 2.1.1/1.
If operator specific barring is applied to a subscription (or existing operator specific barring is modified or removed) by
administrative action in the HLR, the HLR will update the subscription information accordingly. If the mobile
subscriber is registered in the home PLMN, the HLR will transfer the updated subscription information to the VLR and
the SGSN using one or more Insert Subscriber Data operations, as shown in figure2.1.1/ 1.
If the VPLMN does not support Operator Determined Barring of outgoing calls, the VLR and the SGSN shall indicate
this in the acknowledgement of the Insert Subscriber Data message. The HLR shall then, as an operator option, apply
the Outgoing Calls Barred supplementary service, apply barring of roaming as described in subclause 2.3 or take any
other action decided by the operator of the HPLMN.

2.1.2 Invocation of Barring
Barring of outgoing calls or mobile originated short messages is invoked in the VLR. If the VLR receives a request for
subscription information for an outgoing call or mobile originated short message which is prohibited by Operator
Determined Barring, the VLR will return a negative response to the request for subscription information, with an
appropriate error indication. The MSC may relay this error indication via the BSS/RNS to the mobile station over the
radio path, or (in the case of an outgoing call) may connect the mobile station to an address to be determined by the
network operator.
Barring of mobile originated short messages is invoked in the SGSN. If the SGSN receives a request for a mobile
originated short message which is prohibited by Operator Determined Barring, the SGSN will return a negative
response to the request with an appropriate error indication via the BSS/RNS to the mobile station over the radio path.
Barring of all international calls, barring of all international calls except those directed to the home PLMN country,
barring of all premium rate (information) calls or barring of all premium rate (entertainment) calls requires the VLR or
the SGSN to analyse the called number to determine whether the requested call is barred.
Barring of all outgoing calls when roaming outside the home PLMN country requires the HLR to determine whether a
request for location updating originates from a PLMN outside the home PLMN country. If the request does originate
from a PLMN outside the home PLMN country, the HLR will transfer subscription information to the requesting node
to indicate that the mobile station is subject to barring of all outgoing calls.
Operator Specific Barring may apply to outgoing or incoming calls, or mobile originated or mobile terminated short
messages; if it applies to outgoing calls or mobile originated short messages, it is invoked in the VLR or the SGSN, as
described above. If the barring applies to calls directed to a specific class of destination, the called number must be
analysed to determine whether the requested call is barred.
Indicative message flow diagrams for the handling of Operator Determined Barring of outgoing calls or mobile
originated short messages are given in figures 2.1.2/1 and 2.1.2/2. For the case where the mobile station is connected to
an address determined by the network operator, this address is assumed to be directly connected to the MSC, so that no
inter-MSC signalling is required.

Messages
2.2.1 Application or Change of Barring in the HLR
If barring of incoming calls or mobile terminated short messages is applied to a subscription (or existing barring of
incoming calls or mobile terminated short messages is modified or removed) by administrative action in the HLR, the
HLR will update the subscription information accordingly. It is not necessary to transfer the updated subscription
information to the VLR or the SGSN.
2.2.2 Invocation of Barring
Barring of incoming calls is invoked in the HLR. If the HLR receives a request for routing information for a call
directed to a mobile station which is subject to barring of incoming calls, the HLR will return a negative response to the
request for routing information, with an appropriate error indication. The Gateway MSC may relay this error indication
to the originating network using the appropriate telephony signalling system, or may connect the call to a recorded
announcement to be determined by the network operator.
Barring of mobile terminated short messages is invoked in the HLR. If the HLR receives a request for routing
information for a short message directed to a mobile station which is subject to barring of incoming calls, the HLR will
return a negative response to the request for routing information, with an appropriate error indication. This error
indication will be relayed to the originating Short Message service centre by the Gateway MSC using the protocol
defined in 3GPP TS 23.040.
Operator Specific Barring may apply to outgoing or incoming calls, or mobile originated or mobile terminated short
messages; if it applies to incoming calls or mobile terminated short messages, it is invoked in the HLR, as described
above.
An indicative message flow diagram for the handling of Operator Determined Barring of incoming calls is given in
figure 2.2.2/1. For the case where the call is connected to an address determined by the network operator, this address is
assumed to be directly connected to the GMSC, so that no inter-MSC signalling is required.

2.3.1 Application or Change of Barring in the HLR/HSS/UDM
If barring of roaming is applied to a subscription (or modified or removed) by administrative action in the
HLR/HSS/UDM, the HLR/HSS/UDM shall update the subscription information accordingly. If the HLR/HSS/UDM
determines from the identity of the VLR and/or the SGSN and/or MME and/or the AMF that the mobile subscriber is
currently registered in a barred PLMN, the HLR/HSS/UDM shall put the barring into effect by using a Cancel Location
operation to the VLR and/or the SGSN and /or to the MME when applied in HLR/HSS or a UECM Deregistration to
AMF when applied in UDM, as shown in figure 2.3.1/1. In the 5G Core case, barring of roaming may be stored in
UDR. Upon change of barring of roaming in UDR, UDM clears also user registration in UDR using Nudr_DM_Update
operation and unsubscribes to changes on barring of roaming data using Nudr_DM_Unsubscribe operation.
If the mobile subscriber is not currently registered in a barred PLMN, the HLR/HSS/UDM shall take no further action.
