Provided is a mobile terminal test apparatus that can shorten a carrier aggregation testing time. The mobile terminal test apparatus includes a call processing units 12-0 to 12-n that transmits and receives a wireless signal between each of the call processing units 12-0 to 12-n and a mobile terminal 2, and makes a call connection suitable for testing conditions as a component carrier between each of the call processing units 12-0 to 12-n and the mobile terminal 2, and a control unit 15 that causes the mobile terminal 2 to perform a handover, and that applies parameters for a SCC that is designated, as parameters for a PCC that is a handover destination, to the call processing unit 12-0 that corresponds to a PCC, and applies parameters for the pre-handover PCC to the call processing unit 12-n that corresponds to the SCC that are designated and thus connects the SCC.
