Technical Field

[0001] This application relates to the field of performance testing, and more particularly to a performance comparison method and apparatus, and a storage medium. Background Technology

[0002] Taking Wi-Fi systems as an example, the current method for comparing the performance of multiple mobile phones is as follows: multiple mobile phones are connected to the router via wired or wireless connections, then the multiple mobile phones communicate with the router, and the performance of the multiple mobile phones is compared based on the signal strength and transmission performance measured during the communication process.

[0003] However, in real-world communication scenarios, mobile phones are all wireless, and the aforementioned wired connection methods do not closely reflect actual communication scenarios, leading to low comparison accuracy. For wireless connection methods, the different environments in which different mobile phones operate can affect the performance measurement of the mobile phones, resulting in low comparison accuracy in subsequent comparisons. Summary of the Invention

[0006] Secondly, embodiments of this application propose a performance comparison method applied to the aforementioned performance comparison device, the method comprising: The signal strength and transmission performance of the multiple devices under test were measured during the communication process, respectively. The signal strengths of the multiple signals are compared to obtain a signal strength comparison result; the transmission performance of the multiple signals is compared to obtain a transmission performance comparison result.

Detailed Implementation

[0010] In order to gain a more detailed understanding of the features and technical content of the embodiments of this application, the implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference and illustration only and are not intended to limit the embodiments of this application.

[0011] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0012] In the following description, references to "some embodiments" refer to a subset of all possible embodiments. It is understood that "some embodiments" may be the same or different subsets of all possible embodiments and may be combined with each other without conflict. It should also be noted that the terms "first, second, third" used in the embodiments of this application are merely for distinguishing similar objects and do not represent a specific ordering of objects. It is understood that "first, second, third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0013] This application provides a performance comparison device 1, such as... Figure 1 As shown, the device 1 may include: multiple radio frequency cables 10, a combiner 11, an antenna 12, and a communication device 13; wherein, the antenna 12 is wirelessly connected to the communication device 13, the antenna 12 is connected to one side of the combiner 11, and the other side of the combiner 11 is connected to the communication interfaces of multiple devices under test 2 through the multiple radio frequency cables 10; the communication interfaces of the multiple devices under test 2 correspond to the same communication type; The communication device 13 communicates with the multiple devices under test 2 sequentially through the antenna 12, the combiner 11 and the multiple radio frequency cables 10 to achieve performance comparison among the multiple devices under test 2.

[0014] The performance comparison device proposed in this application is suitable for scenarios where the performance of multiple devices under test is compared.

[0015] In this embodiment, the networking method between the performance comparison device and the multiple devices under test is as follows: the communication interfaces of the multiple devices under test are respectively connected to one side of the combiner through multiple RF cables, the other side of the combiner is connected to an antenna, and the antenna is wirelessly connected to the communication device. The connection relationship between the performance comparison device and the multiple devices under test in this embodiment is a combination of wired and wireless connections.

[0016] In this embodiment of the application, the device under test can be a tablet computer, mobile phone, personal computer (PC), laptop computer, wearable device, etc. The specific device can be selected according to the actual situation, and this embodiment of the application does not make specific limitations.

[0017] In this embodiment of the application, the loss between multiple radio frequency cables is the same. Only in this way can it be guaranteed that the loss from multiple devices under test to the communication device is consistent.

[0018] For example, if the loss from phone A to the combiner is a dB, the loss from phone B to the combiner is a' dB, the gain of the combiner is b dB, the antenna gain is c dB, and the air interface loss from the antenna to the communication device is d dB, then the loss from phone A to the communication device is ab - c + d, and the loss from phone B to the communication device is a' - b - c + d. When a = a', the loss from phone A to the communication device is the same as the loss from phone B to the communication device. This eliminates the differences caused by different phone antenna gains and phone structures, thus ensuring the fairness of the performance comparison.

[0019] In this embodiment of the application, the communication device is the peer device corresponding to the device under test under the communication type corresponding to the communication interface.

[0020] Optionally, the communication type can be Wi-Fi communication, Bluetooth communication, cellular communication, etc., and the specific type can be selected according to the actual situation. This application embodiment does not impose specific limitations. Accordingly, for Wi-Fi communication, the communication device is a router; for Bluetooth communication, the communication device is a Bluetooth peer device; and for cellular communication, the communication device is a base station device. The specific type can be selected according to the actual situation. This application embodiment does not impose specific limitations.

[0021] For example, such as Figure 2 As shown, for Wi-Fi communication, the communication device is a router; the Wi-Fi communication interfaces of mobile phone A and mobile phone B are respectively connected to the combiner via RF cables, the combiner is connected to the antenna, and a wireless connection is established between the antenna and the router.

[0022] Optionally, each device under test (DUT) includes multiple communication interfaces, each of which corresponds to transmitting one signal. The number of combiners is at least two, and the number of antennas is the same as the number of combiners. Multiple communication interfaces of the same communication type among the multiple DUTs are connected to one combiner via multiple RF cables. Each of the multiple DUTs corresponds one-to-one with the multiple communication interfaces of the same communication type. The transmission of at least two signals from each device under test is achieved simultaneously using at least two combiners and at least two antennas.

[0023] It should be noted that for a single device under test (DUT), different communication interfaces corresponding to different communication types can be configured internally. When comparing performance, the transmission performance of different communication types can be compared. For a specific communication type, a communication interface of that communication type is determined from each DUT, and the communication interfaces of multiple DUTs are connected to a combiner. In this case, the communication interfaces of the multiple DUTs connected to a combiner correspond to the same communication type.

[0024] For example, mobile phone A includes two Wi-Fi signals, and mobile phone B includes two Wi-Fi signals. Mobile phone A and mobile phone B each connect one of their Wi-Fi signals to a combiner. If both Wi-Fi signals of mobile phone A are connected to a combiner, the output will only be a single-input single-output (SISO) signal, resulting in multiple-input multiple-output (MIMO) signal distortion.

[0025] It should be noted that, regarding the communication type of Wi-Fi communication, the current device under test (DUT) may include one Wi-Fi communication interface, or it may include two Wi-Fi communication interfaces, and even more recently, it may include three or four Wi-Fi communication interfaces. The specific communication type of the communication interface of the DUT can be selected according to the actual configuration, and this application embodiment does not limit it.

[0026] In the embodiments of this application, the performance comparison device may include one combiner, two combiners or more combiners, depending on the actual situation. The embodiments of this application do not make specific limitations.

[0027] For example, in a scenario where the performance comparison device includes two combiners, the communication line corresponding to combiner 1 can be used to transmit Wi-Fi signals, and the communication line corresponding to combiner 2 can be used to transmit cellular signals; or the communication line corresponding to combiner 1 can be used to transmit cellular signals, and the communication line corresponding to combiner 2 can be used to transmit Bluetooth signals; or the communication line corresponding to combiner 1 can be used to transmit one Wi-Fi signal, and the communication line corresponding to combiner 2 can be used to transmit another Wi-Fi signal. The specific choice can be made according to the actual situation, and this application embodiment does not make specific limitations.

[0028] For example, such as Figure 3As shown, this is another networking method between the performance comparison device and the device under test. Specifically, the communication line corresponding to combiner 1 can be used to transmit one Wi-Fi signal, and the communication line corresponding to combiner 2 can be used to transmit another Wi-Fi signal. At this time, the router acts as a communication device to wirelessly connect with combiner 1 and combiner 2 respectively.

[0029] It should be noted that due to the spectrum overlap between Bluetooth signals and 2.4G Wi-Fi signals, which can cause mutual interference, Bluetooth communication and 2.4G Wi-Fi communication will not be configured to be transmitted simultaneously when configuring multiple communication types for simultaneous transmission.

[0030] Optional, such as Figure 4 As shown, the performance comparison device 1 further includes an attenuator 14; wherein one side of the attenuator 14 is connected to one side of the combiner 11, and the other side of the attenuator 14 is connected to the antenna 12. The attenuator 14 is used to simulate a communication scenario in which the multiple devices under test 2 are located at a preset distance from the communication device 13 by adjusting the transmission signal strength of the multiple devices under test 2.

[0031] In this embodiment, the attenuator can adjust the transmission signal strength of multiple devices under test (DUTs) during communication, thereby simulating communication scenarios where the DUTs are located at different distances from the communication device, such as simulating the DUTs being in the far field of the communication device or simulating the DUTs being in the near field of the communication device. The transmission signal strength can include both the received signal strength and the transmitted signal strength.

[0032] It should be noted that by using an attenuator to simulate the device under test (DUT) being in the far field or near field of the communication device, an attenuation curve of the DUT during the communication process can be obtained. The horizontal axis of the attenuation curve represents the transmitted signal strength of the DUT, and the total axis represents the transmission performance measured under different transmitted signal strengths. Users can intuitively and scientifically compare the performance of different DUTs during the communication process based on the attenuation curve.

[0033] In an alternative embodiment, the attenuator can also be used in a performance comparison device that includes two combiners, such as... Figure 5 As shown, this is another networking method between the performance comparison device and the device under test. Specifically, the Wi-Fi communication interface 1 of mobile phone A and the Wi-Fi communication interface 1 of mobile phone B are connected to combiner 1, the Wi-Fi communication interface 2 of mobile phone A and the Wi-Fi communication interface 2 of mobile phone B are connected to combiner 2, combiner 1 and combiner 2 are connected to one end of the attenuator, the other end of the attenuator is connected to antenna 1 and antenna 2, and antenna 1 and antenna 2 are wirelessly connected to the router.

[0034] Optionally, the performance comparison device further includes: an external measurement terminal connected to the communication device; the external measurement terminal includes a measurement tool; The external measurement terminal uses the measurement tool to measure multiple signal strengths and multiple transmission performances of the multiple devices under test during the communication process; and compares the performance of the multiple devices under test based on the multiple signal strengths and multiple transmission performances.

[0035] In this embodiment of the application, the external measurement terminal is a PC.

[0036] In this embodiment of the application, the signal strength is the Received Signal Strength Indication (RSSI).

[0037] For example, in a Wi-Fi communication scenario, comparing device performance, the RSSI and transmission performance of phones A and B as receivers when the router sends packets can reflect the chip's capabilities. If the RSSI received by phone B is lower than that received by phone A, and phone B's receiving performance is lower than phone A's, then phone B's chip receiving capability is inferior to phone A's. Conversely, when phones send packets, if the router, as the receiver, receives a signal strength from phone B that is weaker than that from phone A (signal strength can be viewed through the router's log information), then phone B's transmitting signal strength and performance are inferior to phone A's, indicating that phone B's chip transmitting capability is inferior to phone A's. Here, chip transmitting capability and chip receiving capability characterize the phone's device performance.

[0038] Understandably, multiple devices under test (DUTs) are connected to a combiner via multiple RF cables, and the combiner is then wired to an antenna. This eliminates environmental interference between the multiple DUTs, thereby improving the accuracy of performance comparison. Furthermore, the wireless communication between the communication equipment and the antenna closely matches real-world communication scenarios, further enhancing the accuracy of performance comparison.

[0039] Based on the above embodiments, this application proposes a performance comparison method, applied to the aforementioned performance comparison device, such as... Figure 6 As shown, the method may include: S101. Measure multiple signal strengths and multiple transmission performances of multiple devices under test during the communication process.

[0040] S102. Compare multiple signal strengths to obtain signal strength comparison results; compare multiple transmission performances to obtain transmission performance comparison results.

[0041] S103. Based on the signal strength comparison results and transmission performance comparison results, determine the equipment performance comparison results among multiple devices under test.

[0042] It should be noted that if the performance of each device under test is under multiple communication types, before performing the performance comparison, it is necessary to configure multiple communication types for simultaneous transmission and the corresponding communication device for each communication type. This is to enable the connection between the corresponding communication interface and the corresponding combiner, as well as between the corresponding combiner and the corresponding communication device, based on the multiple communication types for simultaneous transmission.

[0043] For example, for simultaneous Wi-Fi communication and cellular communication, the corresponding communication devices are configured as a router and a base station, respectively. The Wi-Fi communication interface of the mobile phone is connected to a combiner and an antenna and wirelessly connected to the router, while the cellular communication interface of the mobile phone is connected to a combiner and an antenna and wirelessly connected to the base station.

[0044] It should be noted that during the communication process, the air interface signal between the antenna and the communication equipment can also be captured; based on the equipment performance comparison results, the first device under test with lower performance than the other devices under test can be identified from multiple devices under test; and the equipment performance of the first device under test can be analyzed using the air interface signal.

[0045] It should be noted that other descriptions of the performance comparison method can be found in the description of the performance comparison device, and will not be repeated here.

[0046] Understandably, multiple devices under test (DUTs) are connected to a combiner via multiple RF cables, and the combiner is then wired to an antenna. This eliminates environmental interference between the multiple DUTs, thereby improving the accuracy of performance comparison. Furthermore, the wireless communication between the communication equipment and the antenna closely matches real-world communication scenarios, further enhancing the accuracy of performance comparison.
