Description

  The present invention relates to a mobile terminal test apparatus for testing a mobile communication terminal.

  When a mobile communication terminal such as a mobile phone or a data communication terminal is developed, it is necessary to test whether or not the developed mobile communication terminal can communicate normally. For this reason, a mobile communication terminal to be tested is connected to a test apparatus that operates as a pseudo base station that simulates the function of an actual base station, and communication is performed between the test apparatus and the mobile communication terminal. We are conducting a test to confirm the contents.

  In recent years, mobile communication terminals that support a standard called LTE (Long Term Evolution) and can perform high-speed data communication have become widespread.

  Patent Document 1 describes a test apparatus that can test a mobile communication terminal compatible with LTE.

  LTE allows high-speed data communication, but does not assume a dedicated line for voice calls. For this reason, VoLTE (Voice over Long Term Evolution), in which voice data is transmitted / received by LTE to perform a voice call, has been standardized and used.

  When using VoLTE, the mobile communication terminal establishes a communication path (Default Bearer or Dedicated Bearer) different from that for normal Internet connection, and communicates with an IMS (IP Multimedia Subsystem) that controls VoLTE.

  The mobile communication terminal requests establishment of a communication path using different APNs (Access Point Names) for the communication path for Internet connection and for VoLTE. In the base station, the connection destination is determined based on the APN transmitted from the mobile communication terminal.

  When performing such a VoLTE test, for example, the test apparatus simulates a server for Internet connection or a server for VoLTE connection, and performs a test by communicating with a mobile communication terminal.

  In such a case, the test apparatus selects a connection destination server or assigns an IP (Internet Protocol) address based on the APN transmitted from the mobile communication terminal.

  However, since an APN can be freely set by a mobile communication system operator or a mobile communication terminal user, the test apparatus cannot determine which APN is an APN for VoLTE.

  For this reason, conventionally, an APN “ims” that is frequently used in a VoLTE APN is determined to be an APN for VoLTE, or a communication path for VoLTE is determined based on the reception order of communication path establishment requests. And was processing.

  In such a process, when an APN that is not “ims” is transmitted as an APN for VoLTE, or when a communication path establishment request is transmitted in an order different from the set order, the communication path for VoLTE is correctly set. The test cannot be established, and the test fails midway due to a communication error.

  In such a case, collect the communication log and terminal information, check the APN transmitted by the mobile communication terminal, check the transmission order of communication path establishment requests, and test according to the situation. The software of the device had to be modified, and the efficiency of the test execution was poor.

  Therefore, the present invention can establish a communication path corresponding to an establishment request without collecting software logs and terminal information and correcting software, and can improve test efficiency. The purpose is to provide.

  The mobile terminal test apparatus of the present invention is a mobile terminal test apparatus that tests a mobile terminal by simulating a mobile communication base station according to a set test condition, the display unit displaying an image, When a plurality of communication path establishment requests are received from a mobile terminal during a predetermined time, a list of predetermined information set in each establishment request is displayed on the display unit, and one of the lists is selected from the list The predetermined information selected is stored in advance, and the communication path of the establishment request in which the predetermined information stored among the establishment requests of the communication path received thereafter is set is preset. And a control unit used for communication.

  With this configuration, a list of predetermined information of the communication path establishment request transmitted by the mobile terminal is displayed, one piece of information selected from the list is stored, and then the same information as the stored predetermined information is set. The communication path of the established request is used for communication set in advance. For this reason, the communication path corresponding to the establishment request can be established without collecting the communication log and terminal information and correcting the software, thereby improving the test efficiency.

  In the mobile terminal test apparatus of the present invention, the predetermined information is information indicating a use of the communication path.

  With this configuration, information indicating the usage of the communication path is displayed in a list, information indicating the usage of the selected communication path is stored, and then the communication path of the establishment request in which the information indicating the usage of the stored communication path is set. Is used for preset communications. For this reason, by selecting a communication path to be used for communication set in advance according to information indicating the application, a communication path corresponding to the establishment request can be established, and the test efficiency can be improved.

  In the mobile terminal test apparatus of the present invention, the information indicating the use of the communication path is APN.

  With this configuration, a list of APNs is displayed, the selected APN is stored, and then the communication path of the establishment request in which the stored APN is set is used for preset communication. For this reason, by selecting a communication path to be used for communication preset by the APN, a communication path corresponding to the establishment request can be established, and the test efficiency can be improved.

  In the mobile terminal test apparatus of the present invention, the preset communication is communication with an IMS server.
