Question: Under what condition can a UE in RRC_CONNECTED initiate the UL information transfer procedure to transfer NAS or non-3GPP dedicated information, excluding initial setup or resume scenarios?
Option 1: Whenever SRB1 is established, regardless of the type of information.
Option 2: Only when explicitly requested by the eNodeB via a dedicated signaling message.
Option 3: At any time, without specific radio bearer requirements for NAS or non-3GPP info.
Option 4: Specifically for NAS or non-3GPP dedicated info, no specific SRB condition is mentioned, but for CDMA2000 info, SRB2 must be established.
Explanation: The correct answer highlights the nuanced distinction based on information types. For NAS and non-3GPP dedicated information (excluding setup/resume), no particular SRB requirement is specified, unlike the condition for CDMA2000 info, which necessitates SRB2.
