A mobile network simulator section has a function as least one mobile network simulator which forms a communication line between a test terminal and a connection destination in response to a connection request and which disconnects the communication line in response to a disconnection request. A sequence state display control section displays on a sequence display section of a display device any one of sequences indicating communication procedures and communication transition states between at least the test terminal and the mobile network simulator section with respect to a series of communication tests between the test terminal and the connection destination connected via the communication line. A connection state display control section associates the connection state between the test terminal and the connection destination via the mobile network simulator section with the communication transition state, and displays on a connection state display section of the display device the associated connection state to be linked with a display of the sequences by the sequence state display control section.
