The present invention relates to a mobile terminal testing device for testing a mobile terminal.
In a case where a mobile terminal, such as a mobile phone or a data communication terminal, for performing communication while moving is developed, it is necessary to test whether or not the developed mobile terminal normally performs communication. Therefore, a test is performed to confirm the content of communication by connecting a mobile terminal to be tested to a testing device that operates as a pseudo base station that simulates functions of an actual base station and performing communication between the testing device and the mobile terminal.
Upon executing the test, there is a case where information on the mobile terminal to be tested is necessary. The information on the mobile terminal is set in User Equipment (UE) Capability Information that can be acquired through the communication with the mobile terminal.

Hereinafter, a mobile terminal testing device according to an embodiment of the present invention will be described in detail with reference to the drawings.
In
The mobile terminal testing device 1 includes a terminal information storage unit 11, an information request unit 12, a data reception unit 13, a data conversion unit 14, a data structure information storage unit 15, a character string search unit 16, a Test Case (TC) execution unit 17, and an operation display unit 18.
The terminal information storage unit 11 stores information on the mobile terminal 100 to be tested, for example, for each model of the mobile terminal 100.
The information request unit 12 transmits an RF signal requesting the mobile terminal 100 to transmit UE Capability Information.
The data reception unit 13 receives the UE Capability Information from the mobile terminal 100, and outputs the received UE Capability Information to the data conversion unit 14.
The data conversion unit 14 decodes the received UE Capability Information based on data structure information stored in the data structure information storage unit 15, and generates character string data including parameter names, setting values, and the like as character strings.
The data structure information storage unit 15 stores the data structure information that defines the data structure of the UE Capability Information. The data structure information is written in, for example, Abstract Syntax Notation One (ASN. 1).
The data conversion unit 14 decodes the UE Capability Information based on, for example, the data structure of the UE Capability Information stored in the data structure information storage unit 15 and written in ASN. 1, and generates character string data as shown in
The character string search unit 16 searches the character string data generated by the data conversion unit 14 for information necessary for the test.
The TC execution unit 17 controls the execution of a test case selected by a user. The TC execution unit 17 acquires information on the mobile terminal 100 necessary for the selected test case from the mobile terminal 100.
The operation display unit 18 includes an input unit that accepts an operation input from the user, and a display unit that displays a parameter setting screen, a test result, and the like. The input unit includes a touch pad, a keyboard, a push button, and the like. The display unit includes a liquid crystal display device or the like.
In the present embodiment, the TC execution unit 17 acquires the information on the mobile terminal 100 necessary for the test case selected by the user from the UE Capability Information received from the mobile terminal 100.
The TC execution unit 17 notifies the terminal information storage unit 11 of the information on the mobile terminal 100 necessary for the test case selected by the user and the identification information of the mobile terminal 100 to be tested, and acquires necessary information.
Based on the identification information of the mobile terminal 100, the terminal information storage unit 11 checks whether information on the model of the mobile terminal 100 is stored. In a case where the information necessary for the selected test case is not stored, the terminal information storage unit 11 transmits a signal requesting transmission of the UE Capability Information to the mobile terminal 100 using the information request unit 12. Further, the terminal information storage unit 11 notifies the character string search unit 16 of the information necessary for the selected test case.
The data conversion unit 14 decodes the UE Capability Information received from the mobile terminal 100 based on the data structure information of the UE Capability Information stored in the data structure information storage unit 15 and written in ASN. 1.
In TS38.331 of 3rd Generation Partnership Project (3GPP), which creates wireless communication standards, the data structure of the UE Capability Information is written in ASN. 1. For this reason, in a case where the ASN. 1 defined in TS38.331 is stored in the data structure information storage unit 15, the UE Capability Information is decoded using the data structure defined in TS38.331.
Furthermore, even in a case where the data structure of the UE Capability Information is changed due to a standard version upgrade or the like, it is possible to respond to a newly defined data structure without changing a program by only replacing the data structure information stored in the data structure information storage unit 15 and written in ASN.1 with ASN. 1 which is newly defined in TS38.331.
The data conversion unit 14 outputs the decoded character string data to the character string search unit 16. The character string search unit 16 searches the decoded character string data for the information necessary for the selected test case, the information being notified from the terminal information storage unit 11, and notifies the terminal information storage unit 11 of the searched information.
The terminal information storage unit 11 adds the information notified from the character string search unit 16, updates stored information on the mobile terminal 100, and repeats an information acquisition process from the mobile terminal 100 until all acquirable information is acquired. As a result of acquiring all the acquirable information, the terminal information storage unit 11 notifies the TC execution unit 17 whether or not all the information necessary for the selected test case is available.
The TC execution unit 17 executes test measurement in a case where all the information necessary for the selected test case is available, and executes a next test case without performing the test in a case where all the information necessary for the selected test case is not available.
Note that when a process of searching for the UE Capability Information is selected by a user's operation on the operation display unit 18, the character string search unit 16 may search the decoded character string data for parameters or the like input by the user and display a search result on a display unit of the operation display unit 18.
A test execution control process by the mobile terminal testing device 1 according to the present embodiment, which is configured as described above, will be described with reference to
In step S1, the TC execution unit 17 notifies the terminal information storage unit 11 of the information on the mobile terminal 100 and the identification information of the mobile terminal 100, which are necessary for the test case selected by the user, and the terminal information storage unit 11 checks the information on the model of the mobile terminal 100 from the identification information of the mobile terminal 100. After executing the process in step S1, the terminal information storage unit 11 executes a process in step S2.
In step S2, the terminal information storage unit 11 determines whether or not the information on the mobile terminal 100 is completely acquired.
In a case where it is determined that the information on the mobile terminal 100 is completely acquired, the terminal information storage unit 11 executes a process in step S10. In a case where it is determined that the information on the mobile terminal 100 is not completely acquired, the terminal information storage unit 11 executes a process in step S3.
In step S3, the terminal information storage unit 11 requests the information request unit 12 to establish a communication connection with the mobile terminal 100 (UE). After executing the process in step S3, the terminal information storage unit 11 executes a process in step S4.

After executing the process in step S4, the terminal information storage unit 11 causes the data reception unit 13 to execute a process in step S5.
In step S5, upon receiving the UE Capability Information from the mobile terminal 100, the data reception unit 13 outputs the received UE Capability Information to the data conversion unit 14. After executing the process in step S5, the data reception unit 13 causes the data conversion unit 14 to execute a process in step S6.
In step S6, the data conversion unit 14 decodes the received UE Capability Information based on ASN. 1 stored in the data structure information storage unit 15 to generate the character string data, and outputs the character string data to the character string search unit 16. After executing the process in step S6, the data conversion unit 14 causes the character string search unit 16 to execute a process in step S7.
In step S7, the character string search unit 16 searches the decoded character string data for the information necessary for the test case, and outputs search results to the terminal information storage unit 11. After executing the process in step S7, the character string search unit 16 causes the terminal information storage unit 11 to execute a process in step S8.
In step S8, the terminal information storage unit 11 updates the terminal information on the mobile terminal 100 using the searched information. After executing the process in step S8, the terminal information storage unit 11 executes a process in step S9.
In step S9, the terminal information storage unit 11 determines whether or not acquisition of the acquirable information from the mobile terminal 100 is completed.
In a case where it is determined that the acquisition of the information is completed, the terminal information storage unit 11 causes the TC execution unit 17 to execute the process in step S10. In a case where it is determined that the acquisition of the information is not completed, the terminal information storage unit 11 executes the process in step S4.
In step S10, the TC execution unit 17 determines whether or not all the information necessary for the selected test case is available.
In a case where it is determined that all the necessary information is available, the TC execution unit 17 executes a process in step S12. In a case where it is determined that all the necessary information is not available, the TC execution unit 17 executes a process in step S11.
In step S11, the TC execution unit 17 executes a test skip process of skipping the selected test case without performing the selected test case. After executing the process in step S11, the TC execution unit 17 ends the test execution control process.
In step S12, the TC execution unit 17 executes the selected test case. After executing the process in step S12, the TC execution unit 17 ends the test execution control process.
In the above-described embodiment, the data conversion unit 14 decodes the received UE Capability Information based on the data structure information stored in the data structure information storage unit 15, and generates data including parameter names, setting values, and the like as character strings.
Therefore, the UE Capability Information is decoded based on the data structure information stored in the data structure information storage unit 15, and the character string data is generated. Therefore, the processing loads can be reduced and the change in a data structure can be easily responded.
Further, the data structure information stored in the data structure information storage unit 15 is written in ASN. 1.
Therefore, the UE Capability Information is decoded based on the data structure written in ASN. 1, and the character string data is generated. Therefore, the processing loads can be reduced and the change in a data structure can be easily responded.
