How to apply operator determined barring for User using insert subscriber data?

Question

The HSS/HLR generates an Insert-Subscriber-Data (Stand-Alone) to the MME/SGSN including ODB parameter with the All-packet-Oriented bit.
Is that cause the deletion of the on-going PDP-context/Bearer?
Can you please indicate evidence in the 3GPP specifications.

If the "Location reporting" was request by the PGW/GGSN (into change reporting action in Create-PDP-context response/Create-Sesssion response). Does the MME/SGSN continue reporting on Cell-Id/SAI/TAI change after ODB was generated.

Answer 1

I would like to share my understanding whatever I gained by studying about this procedure.
HSS uses "Insert-Subscriber-Data-Request" message to notify MME about any update in user's subscription data.
Insert-Subscriber-Data-Request message has "Subscription-Data" AVP which in turn has sub AVP "Operating-Determined-Barring" AVP. Operator-Determined-Barring AVP is of type unsinged 32 and it contains bitmask to represent each different barring class.

bit 0 to 8 are defined and on/off of each and individual bit notify to MME that which of the feature/service is barred.
