Does this initial CCRequest has the "Flowdescription" AVP in this ?
A. No, there will not be any Flow in CCR-I as through NAS it is not possible for UE to request flow during attach
During UE's request to create a dedicated bearer to update default or dedicated bearer Flows will go in Packet-Filter-Information towards PCRF. PCRF will then take qos and flows requested in Packet-Filter-Information and send CCA with Charging-Rule-Install
Now dedicated bearer 1 is deleted, then what does the PGW send to PCRF ?
A. Hoping this request to delete the filters/bearer is from UE side
PGW will send the packet filter ids to PCRF in Packet-Filter-Information and Packet-Filter-Operation as DELETION. Now PCRF will send Charging-Rule-Remove for all the rules mapped to those filters.
PGW on analyzing that all the rules mapped to Ded1 are removed will trigger a Delete Bearer Request to SGW
Another question: As of now I am storing the list of PolicyRules in PCRF, based on IMSI (IPAddress)..i.e c++ map of IPAddress and PolicyRules. But when the dedicated bearer is removed how do i access the map ? (to find which Policy is deleted)
A. I am not in develop so could not help much here. Can you rephrase it in simple terms. I'll try to sort something out
