2.6 Barring of Network initiated PDP context activation |R4| p. 20

Barring of Network initiated PDP context activation shall be performed based on the Operator Determined Barring for Packet Oriented Services defined in 3G TS 22.041.

2.6.1 Application or Change of Barring in the HLR p. 20

If barring of Packet Oriented Services is applied to a subscription (or existing barring of Packet Oriented Services 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 SGSN.

2.6.2 Invocation of Barring p. 20

Barring of Network initiated PDP context activation is invoked in the HLR. If the HLR receives a request for routing information for a PDP context activation directed to a mobile station which is subject to barring of Packet Oriented Services, the HLR will return a negative response to the request for routing information, with an appropriate error indication. The GGSN may relay this error indication to the PDP PDU incoming network using the appropriate interworking.

An indicative message flow diagram for the handling of Operator Determined Barring of Network initiated PDP context activation is given in Figure 2.6.2-1.

2.6A Barring of existing PDP contexts |R6| p. 21

Barring of existing PDP contexts shall be performed based on the Operator Determined Barring for Packet Oriented Services defined in 3G TS 22.041.

2.6A.1 Application or Change of Barring in the HLR p. 21

If barring of Packet Oriented Services is applied to a subscription (or existing barring of Packet Oriented Services 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 SGSN using one or more Insert Subscriber Data operations, as shown in Figure 2.6A.1-1.

If the VPLMN does not support Operator Determined Barring of Packet Oriented Services, the SGSN shall indicate this in the acknowledgement of the Insert Subscriber Data message. The HLR shall then, as an operator option, apply barring of roaming as described in clause 2.3 or take any other action decided by the operator of the HPLMN.

2.6A.2 Invocation of Barring p. 22

Barring of existing PDP contexts is invoked in the SGSN. If the SGSN receives Insert Subsciber Data message due to barring of Packet Oriented Services is applied to a subscription (or existing barring of Packet Oriented Services is modified or removed) by administrative action in the HLR, the SGSN shall take the following action depending on barring category when one or more PDP contexts exist in SGSN.

For "bar subscribers completely from the Packet Oriented Services", SGSN shall deactivate all existing PDP contexts.
For "bar a subscriber from requesting Packet Oriented Services from access points that are within the HPLMN whilst the subscriber is roaming in a VPLMN", SGSN shall check whether or not the subscriber is located in the HPLMN. If it is not and the GGSN being accessed is located in HPLMN, then all associated PDP contexts with this path shall be deactivated..
For "bar a subscriber from requesting Packet Oriented Services from access points that are within the roamed to VPLMN", SGSN shall check whether or not the subscriber is located in the HPLMN. If it is not and the GGSN being accessed is located in VPLMN, then all associated PDP contexts with this path shall be deactivated.

2.6B Barring of existing EPS Bearer contexts |R8| p. 22

Barring of existing EPS Bearer contexts shall be performed based on the Operator Determined Barring for Packet Oriented Services defined in TS 22.041.

2.6B.1 Application or Change of Barring in the HSS p. 22

If barring of Packet Oriented Services is applied to a subscription (or existing barring of Packet Oriented Services is modified or removed) by administrative action in the HSS, the HSS shall update the subscription information accordingly, and transfer the updated subscription information to the MME using one or more Insert Subscriber Data operations, as shown in Figure 2.6B.1-1.

If the VPLMN does not support Operator Determined Barring of Packet Oriented Services, the MME shall indicate this in the acknowledgement of the Insert Subscriber Data message. The HSS shall then, as an operator option, apply barring of roaming as described in clause 2.3 or take any other action decided by the operator of the HPLMN.

2.6B.2 Invocation of Barring p. 22

Barring of existing EPS Bearer contexts is invoked in the MME. If the MME receives Insert Subscriber Data message due to barring of Packet Oriented Services being applied to a subscription (or existing barring of Packet Oriented Services is modified) by administrative action in the HSS, the MME shall take the following action depending on barring category when one or more EPS Bearer contexts exist in MME.

For "bar subscribers completely from the Packet Oriented Services", MME shall deactivate all existing EPS Bearer contexts.
For "bar a subscriber from requesting Packet Oriented Services from access points that are within the HPLMN whilst the subscriber is roaming in a VPLMN", MME shall check whether or not the subscriber is located in the HPLMN. If it is not and the PDN-GW being accessed is located in HPLMN, then all associated EPS Bearer contexts with this path shall be deactivated.
For "bar a subscriber from requesting Packet Oriented Services from access points that are within the roamed to VPLMN", MME shall check whether or not the subscriber is located in the HPLMN. If it is not and the PDN-GW being accessed is located in VPLMN, then all associated EPS Bearer contexts with this path shall be deactivated.

2.6C Barring of existing PDU Sessions |R15| p. 23

Barring of existing PDU Sessions shall be performed based on the Operator Determined Barring for Packet Oriented Services defined in TS 22.041.

2.6C.1 Application or Change of Barring in the UDM p. 23

If barring of Packet Oriented Services is applied to a subscription (or existing barring of Packet Oriented Services is modified or removed) by administrative action in the UDM, the UDM shall update the subscription information accordingly, and transfer the updated subscription information to the AMF using Nudm_SDM Notification operation, as shown in Figure 2.6C.1-1.

(⇒ copy of original 3GPP image)

2.6C.2 Invocation of Barring p. 23

Barring of existing PDU Sessions is invoked in the AMF. If the AMF receives Nudm_SDM Notification message due to barring of Packet Oriented Services being applied to a subscription (or existing barring of Packet Oriented Services is modified) by administrative action in the UDM, or if the new AMF received the barring of Packet Oriented Services from the UDM during a mobility registration procedure, the AMF shall take the following action depending on barring category when one or more PDU Sessions exist in AMF.

For "bar subscribers completely from the Packet Oriented Services", AMF shall request SMF to release all existing PDU Sessions.
For "bar a subscriber from requesting Packet Oriented Services from access points that are within the HPLMN whilst the subscriber is roaming in a VPLMN", AMF shall check whether or not the subscriber is located in the HPLMN. If it is not and the SMF being accessed is located in HPLMN, then all associated PDU Sessions with this path shall be released by the SMF on request of the AMF.
For "bar a subscriber from requesting Packet Oriented Services from access points that are within the roamed to VPLMN", AMF shall check whether or not the subscriber is located in the HPLMN. If it is not and the SMF being accessed is located in VPLMN, then all associated PDU sessions with this path shall be released by the SMF on request of the AMF.
