In still other embodiments, audio output interface 280 includes speakers, external audio output electronics, and the like.
In some embodiments, user interface 290 is an interface that can be used to receive control inputs (e.g., physical keys on the body of the display device, or the like).
In specific implementation, the terminal 30 to be tested may be a mobile phone, a tablet computer, a handheld computer, a Personal Computer (PC), a cellular phone, a Personal Digital Assistant (PDA), a wearable device (such as a smart watch), a smart home device (such as a television), a vehicle-mounted computer, a game machine, and an Augmented Reality (AR) \ Virtual Reality (VR) device, and the like, and this embodiment does not specially limit the specific device form of the terminal 30 to be tested.
Based on the test system in fig. 1, an embodiment of the present invention provides a flowchart of a method for automatically testing a modem, as shown in fig. 3, the method may be executed by the test host 10, and the method includes the following steps:
and S301, acquiring whether the currently configured bandwidth of the meter is the bandwidth supported by the modem in the tested terminal from the base station analog meter.
The measured terminal 30 is preset with a second configuration file, where the second configuration file includes bandwidth information supported by a modem of the measured terminal. Therefore, in this step, the test host 10 may first obtain the second configuration file from the terminal under test, and the test host 10 obtains the bandwidth information supported by the modem of the terminal under test from the second configuration file, and then, determine whether the currently configured bandwidth is the bandwidth supported by the modem in the terminal under test according to the bandwidth information supported by the modem of the terminal under test 30. If yes, the following step S302 is continued, otherwise, the bandwidth reconfiguration is returned. Therefore, after the bandwidth configuration of the base station simulation instrument is changed every time, only a tester needs to click an execution button in the adaptation software to execute the following actions for adaptation. In the method, the correct test bandwidth configuration ensures that the terminal to be tested can be successfully synchronized to the target cell, and the reliability of test execution is ensured.
S302, if yes, acquiring port configuration information from a first configuration file of the program-controlled combiner; and configuring the program-controlled combiner according to the configuration information.
The port configuration information comprises information of an input antenna port of the program-controlled combiner corresponding to the currently configured bandwidth, information of an antenna port of the base station simulation instrument corresponding to the currently configured bandwidth, information of an output antenna port of the program-controlled combiner corresponding to the currently configured bandwidth, and information of an antenna port of the tested terminal corresponding to the currently configured bandwidth.
S303, sending a control command to the tested terminal through the data line; the control command triggers the tested terminal to start up and search for the network, and sends a measurement report to the base station simulation instrument after the network is successfully searched.
Illustratively, when the control command is a cell handover command, the test host 10 receives the cell handover control command, accesses the target cell by using the configuration parameters of the candidate target cell included in the control command when the handover condition is satisfied, synchronizes with the target cell, initiates a random access procedure in the target cell, and generates a measurement report of the target cell.
That is to say, the test host 10 may integrate a script file or a program plug-in advance, when the test host 10 runs the script file or the program plug-in, the software may be used to automatically implement that the base station analog instrument antenna port and the modem antenna port corresponding to the current test bandwidth maintain a path, and may also detect whether the current test bandwidth is the bandwidth supported by the terminal under test, and this method may improve the problems of low efficiency, easy mismatch and missing configuration, etc. existing in the existing manual configuration, and improve the reliability of the test result of the modem instrument and the test execution efficiency.
In a possible implementation, after sending the measurement report to the base station analog meter, the method further includes S304:
and acquiring the actual transmitting power of the target cell from the base station simulation instrument and the transmitting power of the target cell from the measurement report, determining a path loss value according to the actual transmitting power and the transmitting power of the target cell, and calibrating the base station simulation instrument according to the path loss value, so that the actual transmitting power of the target cell after calibration is consistent with the transmitting power of the target cell in the measurement report.
In one possible embodiment, calibrating the base station analog meter according to the path loss value includes:
when the sum of the actual transmitting power of the target cell and the path loss value is larger than or equal to the maximum transmitting power of the base station simulation instrument, the cell actual transmitting power of the base station simulation instrument is reduced, and the sum of the adjusted actual transmitting power and the path loss value is smaller than the maximum transmitting power of the base station simulation instrument.
In other words, when the test host 10 runs the script file or the program plug-in, the software may issue an at (attention) command through the data line to start the modem, and the modem sends a measurement report to the base station analog instrument after being on the network; software can be used for interactively acquiring the configuration transmitting power of the currently opened cell and the transmitting power of the cell in a measurement report of a modem through a base station simulation instrument, and the difference value of the configuration transmitting power of the currently opened cell and the transmitting power of the cell in the measurement report of the modem is the path loss; if the sum of the cell configuration transmitting power and the path loss exceeds the maximum transmitting power of the instrument, the cell configuration transmitting power is interactively reduced through the base station simulation instrument to enable the sum of the cell configuration transmitting power and the path loss not to exceed the maximum transmitting power of the instrument, and if the sum of the cell configuration transmitting power and the path loss does not exceed the maximum transmitting power of the instrument, the next step is continuously executed; the adaptation software fills the calculated path loss serving as path loss compensation into a path loss compensation configuration file of the base station analog instrument through interaction of the base station analog instrument, so that the consistency of the actual power of the cell and the cell power in a measurement report of the modem can be ensured. Therefore, the method can realize the compensation and calibration of the measurement path loss under different bandwidths.
To more systematically describe the above-described testing method, the following description is made with reference to an interaction flow chart shown in fig. 4.
