  • Patent number: 9313682
    Abstract: To provide a test device and a test method which enable a tester to easily check the allocation of physical channels when testing a mobile communication terminal which performs communication using a time division duplex system and a code division multiple access system. An allocation status display control unit of a test device generates an allocation status display screen 46 indicating the correspondence of the physical channels to a time slot and a channelization code for each connection status on the basis of allocation setting information which is acquired and specified by a setting information acquisition unit. Therefore, the operator can easily check an allocation status for each connection status.
