Question: During an E-UTRAN to cdma2000 1xRTT handover (except for 1xRTT CS Fallback), what is included in the RRC Handover FROM E-UTRA PREPARATION REQUEST message sent by the eNB to the UE?
Option 1: Only the target RAT type
Option 2: Only cdma2000 specific 1xRTT access parameters
Option 3: Both the specified target RAT type and cdma2000 specific 1xRTT access parameters needed by the UE
Option 4: Neither, as these details are handled by the MME
Explanation: This is correct because, according to the handover procedure from E-UTRAN to cdma2000 1xRTT, the eNB's RRC Handover FROM E-UTRA PREPARATION REQUEST message must include both the target RAT type and necessary cdma2000 specific 1xRTT access parameters, enabling the UE to properly prepare for handover by creating an appropriate 1xRTT Origination Request message.
