Yes it is possible. UE can have multiple PDN connection with same APN. UE can request an IP-CAN session with only ipv4 address and similarity it can again request a ipv6 session with same APN

Hi Peeyush, have u tested this case or is it just based on your observation ?
This is a practical scenario where MME does not support the request of multiple IP in a single request message. I don't remember that flag name. Maybe you can fig deep in GTPv2 spec for reference.
Yes, I have tested this however in lab environment.

If you are talking about multiple Gx sessions, please note that Gx session is in between PGW and PCRF.
UE has EPS bearer established from UE to PGW, and of course UE can have multiple EPS bearers established with the same APN.

Consider UE has connected with multiple PDN connection each contains an different APN information, when we modify APN-AMBR value for both APNs at the same time in HSS and initiated HSS Initiated Subscribed QOS modification procedure, HSS sends Insert Subscriber data to MME with modified APN-AMBR information of both APN to MME, But MME forwards only first modified APN-AMBR information to S-GW in Modify Bearer Command message.
Please can anyone explain why MME does not forward second APN-AMBR information to S-GW ???. Whether the scenario is right either we can modify multiple APN-AMBR informations of single UE at the same time
