Question: In which RRC state does a UE initiate the UL information transfer procedure to transfer dedicated inter-RAT information?
Option 1: RRC_CONNECTED
Option 2: RRC_IDLE
Option 3: RRC_INACTIVE
Option 4: RRC_SUSPENDED
Explanation: According to the 3GPP specification, a UE in RRC_CONNECTED state initiates the UL information transfer procedure whenever there is a need to transfer dedicated inter-RAT information. This highlights the importance of the RRC_CONNECTED state in facilitating the exchange of dedicated inter-RAT information between the UE and the network.
