The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a system for testing a screen trip point of a mobile terminal according to an embodiment of the present invention. The system 10 for testing screen jumping points of a mobile terminal comprises a control terminal 11 and a comprehensive tester 12, wherein the control terminal 11 is coupled to the comprehensive tester 12 and is also coupled to the mobile terminal 20, and the comprehensive tester 12 establishes a communication connection with the mobile terminal 20. In addition, the system 10 may further include a shielding box 13, wherein the integrated tester 12 is coupled to the shielding box 13, and the mobile terminal 20 is disposed in the shielding box 13, so that when the integrated tester 12 establishes a communication connection with the mobile terminal 20, interference of other external signals can be shielded by the shielding box 13, and accuracy of the test can be ensured.
Specifically, please refer to fig. 2, wherein fig. 2 is a flowchart illustrating a method for testing a screen jump point of a mobile terminal according to a first embodiment of the present invention, which can be performed by using the system 10 shown in fig. 1. The method for testing the screen jumping point of the mobile terminal comprises the following steps:
step 101: and enabling the comprehensive tester to work under the current test channel in the selected current test frequency band.
In a specific implementation scenario, the control terminal 11 is connected to the comprehensive tester 12 through a GPIB (General-Purpose Interface Bus) line. The control terminal 11 selects one channel in one test frequency band as a current channel in the current test frequency band, and sends the current channel in the current test frequency band to the comprehensive tester 12, so that the comprehensive tester 12 works under the channel in the test frequency band selected by the control terminal 11.
The control end 11 may be a computer or a controller, and related testing software is installed therein, so that a user can set the comprehensive tester 12 by operating the testing software.
In other implementation scenarios, the control end 11 may also be connected to the comprehensive tester 12 in other manners, such as a USB cable or other interface bus, or may be wirelessly connected through bluetooth, WIFI, or the like.
Step 102: and establishing communication connection between the mobile terminal and the comprehensive tester under the current test channel in the selected current test frequency band so that the mobile terminal works under the current test channel in the selected current test frequency band.
In a specific implementation scenario, the mobile terminal 20 establishes a communication connection with the integrated tester 12, the integrated tester 12 is equivalent to a virtual base station, the mobile terminal 20 receives a radio frequency signal sent by a base station (BCH broadcast channel) during operation, and starts to search for a signal in the channel, and once a strongest broadcast channel is found, the internal frequency timing is adjusted to synchronize the mobile terminal with the strongest broadcast channel. This process is a synchronization process of the mobile terminal and the base station, and the synchronization process of the mobile terminal 20 and the integrated tester 12 is the same principle. Since the integrated tester 12 operates under the current test channel in the selected current test frequency band, the mobile terminal 20 also operates under the current test channel in the selected current test frequency band.
In another specific implementation scenario, the mobile terminal 20 is disposed in the shielding box 13, and the integrated instrument 12 is coupled to the shielding box 13, so that when the integrated instrument 12 establishes a communication connection with the mobile terminal 20, interference of other external signals can be shielded by the shielding box 13, and accuracy of the test is ensured.
In another specific implementation scenario, the integrated tester 12 may control the transmission power of the mobile terminal 20 to operate at the highest power, in addition to controlling the mobile terminal 20 to operate at the current test channel in the selected current test frequency band. Since the probability of the screen jump of the mobile terminal 20 is proportional to the operating power of the mobile terminal 20, the higher the operating power, the higher the probability of the screen jump occurring.
Step 103: and sending a screen jumping point test instruction to the mobile terminal through the control terminal.
In a specific implementation scenario, the control end 11 is coupled to the mobile terminal 20, and the control end 11 sends a screen trip point test instruction to the mobile terminal 20 when detecting that the mobile terminal 20 has operated at the highest power in the current test channel in the selected current test frequency band.
Step 104: and the mobile terminal performs the screen jumping point test under the current test channel in the selected current test frequency band according to the screen jumping point test instruction, detects whether the own screen has a jumping point problem and generates a corresponding detection result.
In a specific implementation scenario, when the mobile terminal 20 starts testing according to the screen jump point test instruction, the mobile terminal 20 is already operating in the current test channel in the selected current test frequency band. In this implementation scenario, the screen jumping point test command includes a scan signal, which sequentially scans each point on the screen of the mobile terminal and simultaneously monitors whether other points on the screen of the mobile terminal 20, except for the currently scanned point, also respond to the scan signal. If a situation occurs in which other points on the screen of the mobile terminal 20 than the currently scanned point also respond to the scan signal, the point of this response is a skip point. At this time, the control end 11 saves the position of the responding point and the current test channel in the current test frequency band. The screen jump test continues until all points on the screen of the mobile terminal 20 have been tested.
Referring to fig. 3, fig. 3 is a flowchart illustrating a second embodiment of a method for testing a screen trip point of a mobile terminal according to the present invention, wherein the method for testing a screen trip point of a mobile terminal according to the present invention includes the following steps:
step 201: and after the mobile terminal completes the screen jumping point test under the current test channel in the selected current test frequency band, controlling the integrated tester to be switched to the next test channel in the current test frequency band, wherein the next test signal in the switched current test frequency band is used as the current test channel in the selected current test frequency band.
In a specific implementation scenario, after the mobile terminal 20 completes the jumping point test on all the points on the screen under the current test channel in the current test frequency band, the control end 11 controls the integrated tester 12 to switch to the next test channel in the current test frequency band, in this implementation scenario, every two adjacent test channels in the current test frequency band are separated by 5 channels, and the next test signal in the switched current test frequency band is used as the current test channel. In other implementation scenarios, any number of channels may be separated by 3, 7, 10, etc., and it is only necessary to keep the number of channels separated between two adjacent channels constant.
Step 202: and under the current test channel in the selected current test frequency band, continuing to enable the mobile terminal to establish communication connection with the comprehensive tester, and enabling the mobile terminal to continue to perform screen jumping point detection.
In a specific implementation scenario, the integrated tester 12 operates in the next test channel in the current test frequency band, and continues to establish a communication connection between the mobile terminal 20 and the integrated tester 12, so that the mobile terminal 20 also operates in the next test channel in the current test frequency band, and in other implementation scenarios, the integrated tester 12 may further control the transmission power of the mobile terminal 20, so that the next test channel in the current test frequency band operates at the maximum power and maintains the maximum power to complete a new round of screen jumping point test.
Step 203: and after the screen jumping point test is finished under all the test channels in the selected current test frequency band, the mobile terminal controls the comprehensive tester to switch to a test channel in another test frequency band, wherein the test channel in the other switched test frequency band is used as the current test channel in the selected current test frequency band.
In a specific implementation scenario, the mobile terminal 20 has completed the screen jump test under all the selected test channels of the selected current test frequency band, and the control terminal 11 controls the integrated tester 12 to switch to a test channel in another test frequency band to start the test at this time, and the test channel in the another test frequency band after the switch is used as the current test channel in the selected current test frequency band. In this implementation scenario, the test channel switched to another test frequency band is the test channel with the lowest frequency of the frequency band, a fixed number of channels are sequentially spaced, and the next test channel in the current test frequency band is selected until the end of the channel with the highest frequency of the current test frequency band. In other implementation scenarios, the testing may also be started from the channel with the highest frequency in the current testing frequency band, a fixed number of channels are sequentially spaced, and the next testing channel in the current testing frequency band is selected until the end of the channel with the lowest frequency in the current testing frequency band. Or may be any other rule for selecting a test channel.
The frequency bands tested in this implementation scenario include: GSM850, GSM900, DCS and PCS bands, in any order. In other implementation scenarios, the communication system may further include various communication frequency bands such as CDMA2000, WCDMA, TD-SCDMA, LTE, NR, and the like.
Step 204: and under the current test channel in the selected current test frequency band, continuing to enable the mobile terminal to establish communication connection with the comprehensive tester, and enabling the mobile terminal to continue to perform screen jumping point detection.
Similar to step 202, the step is that the control terminal 11 controls the integrated tester 12 to operate under the current test channel in the selected current test frequency band, so that the mobile terminal 20 also operates under the current test channel in the selected current test frequency band, and in other implementation scenarios, the integrated tester can control the transmitting power of the mobile terminal, so that the next test channel in the current test frequency band operates at the maximum power and maintains the maximum power to complete a new round of screen jumping point test.
Briefly, in the system and method for testing screen jumping point of a mobile terminal of the present invention, when operating, the control terminal 11 selects one of GSM850, GSM900, DCS and PCS frequency bands as a current testing frequency band, for example, GSM850 is selected as the current testing frequency band, GSM850 includes 124 channels of channel numbers 128-251, and among the 124 channels, channel number 128 with the lowest frequency is selected as the current testing channel of the current testing frequency band. The control end 11 controls the integrated tester 12 to work under the channel number 128 of the GSM 850. The mobile terminal 20 establishing communication connection with the integrated instrument 12 also operates under the channel number 128 of the GSM850, and the integrated instrument 12 can also control the transmitting power of the mobile terminal 20, so that the integrated instrument 12 can control the mobile terminal 20 to maintain maximum power operation under the channel number 128 of the GSM 850. At this time, the control terminal 11 sends a screen jumping point test command to the mobile terminal 20. In this implementation scenario, the screen jumping point test instruction includes a scan signal, which sequentially scans each point on the screen of the mobile terminal 20, and the control terminal 11 monitors whether other points on the screen of the mobile terminal 20 except the currently scanned point also respond to the scan signal. If it appears that other points on the screen of the mobile terminal 20 than the currently scanned point also respond to the scan signal, the point of this response is a skip point. At this time, the control end 11 stores the position of the responding point, the current test frequency band and the current test channel, for example, the channel No. 128 of GSM850 in this implementation scenario. The screen jump test continues until all points on the screen of the mobile terminal 20 have been tested.
After testing all the points on the screen of the mobile terminal 20 in the channel number 128 of the GSM850, the control terminal 11 controls the integrated instrument 12 to switch to operate in the channel number 133 of the GSM850, and the mobile terminal 20 establishing a communication connection with the integrated instrument 12 also switches to operate in the channel number 133 of the GSM850, and meanwhile, the integrated instrument 12 can also control the transmission power of the mobile terminal, so that the integrated instrument 12 can control the mobile terminal 20 to maintain maximum power operation in the channel number 133 of the GSM 850. At this time, the control terminal 11 sends a screen jumping point test command to the mobile terminal 20. The contents of the screen jump test are similar to those in channel number 128 of GSM850, and are not described here again.
By analogy, after the test is completed under the current channel, the control end 11 controls the integrated tester 12 to switch to the next channel which is separated from the current channel by 5. Until the test is completed under all channels of the GSM850 frequency band. In other implementation scenarios, the interval between the current channel and the next channel may also be 3, 7, or 10, and it is only necessary to note that the number of channels between the current channel and the next channel is fixed.
After all channels of the GSM850 frequency band are tested, the control end 11 controls the integrated tester 12 to switch the current test frequency band to the GSM900, and the screen jumping point test under all channels of the GSM900 frequency band is sequentially completed with 5 channels as intervals from the 1 st channel with the lowest frequency in the GSM900 frequency band. In other implementation scenarios, the test channel may be selected from the channel with the highest frequency until the test is completed on all channels of the current test frequency band, or may be selected in other sequences.
By analogy, after the test is completed under all channels of the GSM900 frequency band, the control end 11 controls the integrated tester 12 to switch to the next frequency band to be tested, for example, the DCS frequency band. After switching to the DCS band, the screen jumping point test under all channels of the current band is sequentially completed at intervals of 5 channels from the band with the lowest frequency, as with other bands. And switching to the next frequency band to be tested, wherein the frequency bands to be tested have no fixed arrangement sequence and only need to comprise GSM850, GSM900, DCS and PCS, and in other implementation scenes, the frequency bands can also comprise various communication frequency bands such as CDMA2000, WCDMA, TD-SCDMA, LTE, NR and the like.
According to the invention, the working frequency band and channel of the integrated tester are controlled by the control end, so that the working frequency band and channel of the mobile terminal which is in communication connection with the integrated tester are switched, the mobile terminal can be controlled by the integrated tester to work at the highest power under the test channel of the current test frequency band, the probability of finding the jumping point problem is improved, each test frequency band is started from the channel with the lowest frequency, and the screen jumping point test is completed under all the channels of each test frequency band at intervals of a fixed number of channels. The test coverage rate is high, and the reliability is high.
Different from the prior art, the invention can ensure that the mobile terminal works at the highest power under the current test channel in the selected current test frequency band, a preset number of communication channels are arranged between every two adjacent test channels at intervals, all selected test channels of the selected test frequency band are measured in sequence, the test coverage is wide, and the test reliability is high.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
