  In order to solve the above problems, the present inventors have studied from various aspects. As described above, with the method of measuring communication quality from the mobile communication network side, it is difficult to target a plurality of mobile devices. Therefore, it was studied that dozens of measurers each operate two to three mobile devices and perform communication quality measurement by performing operations such as calling at a timing determined by each. However, in this method, it is difficult to measure by increasing the number of mobile devices, and it is difficult to change the measurement sequence in consideration of the communication state in each mobile device. The present invention has been made based on these findings.

In this case, the sequence selection output means preferably selects and outputs sequence information that suppresses a predetermined communication operation performed with the mobile communication network for a plurality of mobile devices. Since the sequence information that suppresses the communication operation of the mobile device is output when the call origination / termination completion rate falls below a predetermined value, it is possible to avoid performing a test with an excessive load on the mobile communication network.

In the communication quality analysis system of the present invention, the information acquisition means acquires information including success or failure of transmission to the mobile communication network as communication quality information, and the quality analysis means transmits information to the mobile communication network in each of a plurality of mobile devices.

Since the transmission completion rate and the unit call volume are calculated and displayed on the result display means, the result of analyzing the communication quality can be easily confirmed.

  In the communication quality analysis system of the present invention, based on the communication quality analyzed by the quality analysis means, information indicating the communication quality analyzed at predetermined time intervals is stored, and the stored communication quality is displayed as information. It is also preferable to provide a result creation means for creating a based graph. Since the graph based on the communication quality can be created, the result of analyzing the communication quality can be visually confirmed.

  The communication quality analysis system of the present invention preferably further includes a result transmission unit that transmits information indicating a communication quality stored by the result generation unit and a graph to a predetermined transmission destination device via a network. Since information and a graph indicating communication quality can be transmitted to a predetermined communication destination device, for example, information transmitted from a plurality of communication quality analysis systems can be collected and analyzed.
