## Abstract

Provided is a mobile terminal testing apparatus capable of executing a test for putting any pseudo base station out of service during state transition, such as during handover or during position registration. A mobile terminal testing apparatus includes a plurality of pseudo base station units 18-1, 18-2, and 18-3 that simulate a plurality of base stations, and a scenario processing unit 17 that controls the pseudo base station units 18-1, 18-2, and 18-3 in compliance with a set scenario to execute a test. The scenario processing unit 17 puts the pseudo base station units 18-1, 18-2, and 18-3 set as a base station executing an out-of-service test out of service in a case where a message set as a message to execute the out-of-service test is transmitted from the pseudo base station units 18-1, 18-2, and 18-3 set as a base station transmitting the message to execute the out-of-service test.

## Claims

### Claim 1

A mobile terminal testing apparatus that simulates a plurality of base stations of mobile communication to test a mobile terminal, the mobile terminal testing apparatus comprising:
a plurality of pseudo base station units that simulate the base stations; and
a scenario processing unit that controls the pseudo base station units in compliance with a set scenario to execute a test,
wherein the scenario processing unit puts at least one pseudo base station unit, which is set as a base station executing an out-of-service test, out of service in a case where a message set as a message to execute the out-of-service test is transmitted from one pseudo base station unit set as a base station transmitting the message to execute the out-of-service test.

### Claim 2 (depends on 1)

The mobile terminal testing apparatus according to claim 1,
wherein the scenario processing unit puts the at least one pseudo base station unit set as the base station executing the out-of-service test out of service after a set time elapses in a case where the message set as the message to execute the out-of-service test is transmitted from the one pseudo base station unit set as the base station transmitting the message to execute the out-of-service test.

### Claim 3 (depends on 2)

The mobile terminal testing apparatus according to claim 2,
wherein the scenario processing unit puts a plurality of the pseudo base station units set as the base station executing the out-of-service test cut of service after the set time elapses, respectively, in a case where the message set as the message to execute the out-of-service test is transmitted from the one pseudo base station unit set as the base station transmitting the message to execute the out-of-service test.

### Claim 4

A method of controlling an out-of-service test of a mobile terminal testing apparatus that includes a plurality of pseudo base station units simulating a plurality of base stations of mobile communication and simulates the base stations to test a mobile terminal, the method comprising:
a step of determining whether or not a message set as a message to execute the out-of-service test is transmitted from one pseudo base station unit set as a base station transmitting the message to execute the out-of-service test; and
a step of putting at least one pseudo base station unit set as a base station executing the out-of-service test out of service in a case where the message set as a message to execute the out-of-service test is transmitted from the pseudo base station unit set as the base station transmitting the message to execute the out-of-service test.

### Claim 5 (depends on 4)

The method according to claim 4,
wherein the step of putting the at least one pseudo base station unit set as the base station executing the out-of-service test out of service is a step of putting the at least one pseudo base station unit set as the base station executing the out-of-service test out of service after a set time elapses in a case where the message set as the message to execute the out-of-service test is transmitted from the one pseudo base station unit set as the base station transmitting the message to execute the out-of-service test.

### Claim 6 (depends on 5)

The method according to claim 5,
wherein the step of putting the at least one pseudo base station unit set as the base station executing the out-of-service test out of service is a step of putting a plurality of the pseudo base station units set as the base station executing the out-of-service test out of service after the set time elapses, respectively, in a case where the message set as the message to execute the out-of-service test is transmitted from the one pseudo base station unit set as the base station transmitting the message to execute the out-of-service test.
