What happens if the QCI=1 bearer setup request for VoLTE is rejected due to weak LTE coverage in originating session?
option 1: UE performs UL asynchronous HARQ transmission
option 2: UE performs SRVCC
option 3: UE performs HARQ
option 4: UE performs MU-MIMO
option 5: UE performs CSFB
### Response:
option 5: UE performs CSFB
explanation :If the QCI=1 bearer setup request for VoLTE is rejected due to weak LTE coverage in originating session, the UE performs Circuit Switched FallBack (CSFB).

What is included in the final SIP response for tracking applications generating charging information?
option 1: P-GW address and EPC Charging ID
option 2: MSC address and Call Reference Number
option 3: Address or specific NE identifier of each IMS NE
option 4: Address or identifier of the hosting AS and its application identifier
option 5: IOI identities received in the session signalling
### Response:
option 4: Address or identifier of the hosting AS and its application identifier
explanation :Based on operator policy, each application for which the hosting AS CTF is generating charging events includes the address or identifier of the AS and its application identifier into the initial SIP request. The final SIP response contains the list of addresses, application identifiers, and identifiers received within the initial SIP request.
