Abstract

To provide a mobile terminal test device capable of efficiently testing a mobile terminal compatible with NSA while suppressing a test configuration to be small. A mobile terminal test device includes a first analysis unit 24 a and a second analysis unit 24 b that analyze a signal received from a mobile terminal, a selection unit 22 that selects ports for a first port 21 a , a second port 21 b , a first port 31 a , and a second port 31 b connected to the mobile terminal, and ports connected to the first analysis unit 24 a and the second analysis unit 24 b , and a control unit 6 that causes the selection unit 22 to select the ports to be connected to the first analysis unit 24 a and the second analysis unit 24 b , from a connection state between the port and the mobile terminal.

First claim

What is claimed is:

1. A mobile terminal test device comprising:
two or more analysis units that analyze a signal received from a mobile terminal;
a plurality of ports connected to the mobile terminal, the number of the plurality of ports being more than the number of the two or more analysis units;
a selection unit that is configured to select one of the plurality of ports to be connected to one of the two or more analysis units; and
a control unit that causes the selection unit to select which one of the plurality of ports to be connected to which one of the two or more analysis units, from a connection state between the one of the plurality of ports and the mobile terminal.

2. The mobile terminal test device according to claim 1 , wherein each of the two or more analysis units stores a correction value for correcting a signal received from each port, and corrects the received signal with the correction value corresponding to a connected port, among the plurality of ports.

3. The mobile terminal test device according to claim 1 , wherein;
each of the analysis units stores a correction values for correcting a signal received from some of the ports, and the correction value that is not stored is acquired from the other analysis unit that stores the correction values, and
corrects the received signal with the correction value corresponding to the connected port.

4. The mobile terminal test device according to claim 1 , wherein:
the plurality of ports comprises:
a plurality of first ports provided in a first slot compatible with a first communication standard, and
a plurality of second ports provided in a second slot compatible with a second communication standard,

in a normal state, the two or more analysis units are connected to the plurality of first ports provided in the first slot or the plurality of second ports provided in the second slot, and
when it is determined that one of the plurality of first ports provided in the first slot and one of the second ports provided in the second slot are simultaneously used,
the control unit instructs connection destinations to the two or more analysis units so that a connection destination of the analysis unit includes one of the plurality of first ports provided in the first slot and another connection destination of another analysis unit includes one of the plurality of second ports provided in the second slot.

5. A port connection method of a mobile terminal test device including two or more analysis units that analyze a signal received from a mobile terminal, a plurality of ports connected to the mobile terminal, the number of the plurality of ports being more than the number of the two or more analysis units, and a selection unit that selects one of the plurality of ports to be connected to one of the two or more analysis units, the method comprising:
a step of selecting the one of the plurality of ports to be connected to the one of the two or more analysis units from a connection state between the selected port and the mobile terminal; and
a step of correcting, by the connected analysis unit, a received signal with a correction value corresponding to the selected port.
