In Gx interface, a user can be identified using one of the following identifier:
1. MSISDN - END_USER_E164 format
2. IMSI - END_USER_IMSI
3. SIP URI - END_USER_SIP_URI
4. Network Access Identifier (bob@example.com) - END_USER_NAI
5. END_USER_PRIVATE - It can be derived from IMSI

I used and seen mainly top three UE identifiers from the above list for Gx interface.

Can PCEF initiate back to back CCR messages towards PCRF for IP-CAN session modification for same UE ?

There is one use case here. PCEF has sent CCR (due to IP-CAN session modify) to PCRF and it again sends CCR to (due to another update) without receiving previous CCA. What should be the behavior ?

How sessions between PGW and PCRF is maintained in LTE network?

This regarding the sessions b/w the PGW and PCRF.

Lets say we have 2 default bearers(DEF1, ad DEF2) for UE1, and 2 dediicated bearers for each of these Default bearers. And for UE2 assume 2 def bearers, DEF3, and DEF4.

Now a CCR is sent for initial default bearer DEF1 creation for UE1. Lets say session(session1) is created for this. with CCRequest number=0.
For Ded bearer1 creation, will it use the same session Id ? and increment the CCRNumber ?
What about the UE2?

I am new to Diameter and earlier, these things were internal and didnot need diameter interface. So the questions are arising.
