Lets say we have a session-0 established for the UE (IPaddress1) for the default bearer. This is when the PGW send the CCRequest(cctype=initial and ccnum=0). Lets say "Policy1" is sent by PCRF in CCA. Does this initial CCRequest has the "Flowdescription" AVP in this ?

Now a dedicated bearer1 is established so CCRequest is sent with (ccrtype =modify and ccnum=1). Lets say PCRF assigns "Policy 2".

Now dedicated bearer 1 is deleted, then what does the PGW send to PCRF ?

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)
