Abstract
Description
Technical Field
[0001] The present invention relates to the field of radio frequency technology, and in particular to a terminal radio frequency path testing method and system. Background Art
[0002] Signaling test refers to simulating the call connection of the real network. The signal connection is completed through the handshake message interaction between AP and Station. The instrument plays the role of Station or AP to complete the wireless connection with the device under test and test the wireless performance indicators of the device under test.
[0003] Non-signaling testing refers to entering the factory test mode, where the forced transmission tool directly controls the RF transceiver of the device under test to send RF signals of specified power / specified frequency or forcibly controls the RF transceiver to receive specified RF signals. The comprehensive test instrument directly measures the physical layer RF indicators of the device under test, and there is no protocol interaction above the MAC layer.
[0004] At present, in the process of mobile phone development, when the signaling test method is used to test the RF path of the mobile phone, there are cases of inaccurate testing. This is because the mobile phone and the comprehensive test instrument have the function of automatically addressing signals, so that a certain RF path may still transmit / receive RF signals normally through other RF paths when the logical configuration is wrong, resulting in the inability to identify the logical configuration error of the RF path. Therefore, the "correct" results of the signaling test often mislead engineers' research and development work.
[0005] Since the mobile phone and the comprehensive test instrument do not have the automatic addressing function in the non-signaling state, the non-signaling test can identify the problem of incorrect logical configuration of the RF path itself, but there are still the following defects:
[0006] The forced transmission / reception tools provided by various mobile phone platforms (the tools are used to force the mobile phone to transmit RF signals of preset power / frequency band or receive specified RF signals) can only perform non-signaling tests on a single-band single channel, that is, they can only test whether there is a logical configuration error in the single-band single channel itself, and cannot open two or more channels at the same time, and cannot verify the logical conflicts between different RF channels (referring to the inconsistent logical configurations for the same device in different RF channels working at the same time). This results in that when different RF channels with conflicting logical configurations are used at the same time, the devices with conflicting logical configurations on the RF channels will work abnormally, resulting in a decrease in RF signal quality and a reduction in user experience.

[0044] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0045] For accurate detection of the logical configuration of the RF path, refer to Figure 1 The embodiment of the present invention provides a terminal radio frequency path testing method, comprising:
[0046] S1. Connect the terminal to the comprehensive testing instrument in non-signaling state.
[0047] In the non-signaling state, there is no function of automatic addressing signal between the terminal and the comprehensive test instrument. Specifically, the terminal is connected to the comprehensive test instrument via a USB cable to achieve a non-signaling state connection between the two.
[0048] In this embodiment, the terminal may be any device with a radio frequency communication function, such as a mobile phone, and the embodiment of the present invention does not specifically limit this. The terminal includes a radio frequency transceiver and at least one radio frequency antenna, and the radio frequency transceiver is connected to each radio frequency antenna to form multiple radio frequency paths. These radio frequency antennas can transmit and receive radio frequency signals of a preset frequency band, and the number of radio frequency antennas can be any number such as 2, 3, 4, 6, 8, etc., to meet the communication needs of the terminal.
[0049] S2. Select a radio frequency path from the radio frequency paths provided by the terminal as the current path under test, and perform a multi-path radio frequency test on the current path under test.
[0050] See also Figure 2 , the method of performing multi-channel RF testing on the current tested channel includes:
[0051] S21, while opening the current measured path and its corresponding at least one interference path, closing other RF paths, the interference path is a RF path provided by the terminal that can work simultaneously with the current measured path.
[0052] S22, the control terminal and the comprehensive measuring instrument as a transmitter, the other as a receiver and transmit the RF signal through the current measured path, to obtain the first transmission power and the first receiving power at both ends of the current measured path.
[0053] S23: Determine whether the logic configuration of the current tested path is correct according to a first power difference between the first transmit power and the first receive power.
[0054] Considering that the TX PA output may be affected by temperature, and the RX line loss is averaged due to different insertion losses between channels, the test result will have an expected 2dB to 3dB error. Therefore, optionally, when the first power difference is less than 5dB, it is judged that the logic configuration of the current tested channel is accurate; when the first power difference exceeds 5dB, it is judged that the logic configuration of the current tested channel is inaccurate. Further, when the first power difference is greater than 20dB, it is judged that the logic of the current tested channel is not connected, or the logic configuration of the device on the tested channel is changed when the interference channel is opened; when the first power difference is between 5dB and 20dB, it is judged that some devices of the current tested channel may have logic conflicts or errors, resulting in signal coupling to the current tested channel. Of course, in actual applications, the power difference threshold used as the judgment standard can be flexibly adjusted according to the actual application scenario, and the embodiment of the present invention does not make specific limitations on this.
[0055] It can be understood that in step S2, if the current tested channel is a strong TX channel, the terminal acts as a transmitter to transmit the RF signal through the current tested channel, and the comprehensive testing instrument acts as a receiver to receive the RF signal; conversely, if the current tested channel is a strong RX channel, the comprehensive testing instrument acts as a transmitter to transmit the RF signal, and the terminal acts as a receiver to receive the RF signal through the current tested channel.
[0056] Different from the traditional single-channel test (the test method is: only open the tested channel and close other RF channels), the embodiment of the present invention adopts multi-channel RF test for the tested channel, that is, when the tested channel and its interference channel are opened at the same time, only the first power difference between the first receiving power and the first transmitting power on both sides of the tested channel is tested, and the logic configuration accuracy of the tested channel is judged according to the first power difference.
[0057] It should be noted that each RF path may include various RF devices such as power amplifiers and RF switches. Usually, during the development process, R&D personnel will perform logical configuration on all devices on each RF path in sequence. During the logical configuration of a certain RF path, it may be necessary to reconfigure a certain RF device on other RF paths at the same time. Therefore, for a device on the tested path, there may be the following four logical configuration situations: (1) The tested path's own logical configuration for the device is correct, and the interfering path's logical configuration for the device is correct; (2) The tested path's own logical configuration for the device is correct, and the interfering path's logical configuration for the device is incorrect; (3) The tested path's own logical configuration for the device is incorrect, and the interfering path's logical configuration for the device is incorrect; (4) The tested path's own logical configuration for the device is incorrect, and the interfering path's logical configuration for the device is correct.
[0058] It is understandable that, since the tested path and the interference path are opened at the same time in this embodiment, during the process of the tested path and the interference path working at the same time, if the logic configuration of the tested path and the interference path about the same device is inconsistent (one is correct and the other is incorrect) or both are incorrect, the device can be abnormally operated, and the difference in the receiving and transmitting power on both sides of the tested path obtained by the test exceeds the normal reasonable range. Therefore, the test method of the embodiment of the present invention can accurately determine the logic accuracy of the tested path, including the logic error problem of the tested path itself, and the logic configuration conflict problem between the tested path and the interference path, that is, the aforementioned types (2) to (4) of inaccurate logic configuration can all be detected.
[0059] Furthermore, the terminal RF path testing method provided by the embodiment of the present invention also includes the step of performing a single-path RF test on the current path under test, specifically including: only opening the current path under test, and closing other RF paths except the current path under test; controlling the RF transceiver to transmit RF signals between the current path under test and the comprehensive testing instrument, and obtaining the second transmission power and the second reception power at both ends of the current path under test; judging whether the logical configuration of the current path under test is incorrect based on the second power difference between the second transmission power and the second reception power.
[0060] Based on this, the method for determining whether the logic configuration of the current tested path is correct in step 102 further includes:
[0061] If the logic configuration of the current tested channel is correct and the first power difference exceeds the first threshold, it is determined that there is a conflict in the logic configuration between the interfering channel and the current tested channel; otherwise, it is determined that there is no conflict in the logic configuration between the interfering channel and the current tested channel.
[0062] In this way, by performing a single-channel RF test on the current tested channel, it can be identified whether the current tested channel's own logical configuration is incorrect; when the current tested channel's own logical configuration is correct, based on the test results of the multi-channel RF test of the current tested channel, it can be further identified whether there is a conflict in the logical configuration between the current tested channel and the interference channel.
[0063] In summary, by combining the single-channel RF test results and multi-channel RF test results of the current tested channel, it is possible to accurately distinguish whether the problem is with the "logical configuration of the current tested channel itself" or the "logical configuration of some devices in the interference channel regarding the current tested channel". This can help engineers quickly analyze, locate and solve the problem.
[0064] Considering that in the transmission path, a power amplifier is needed to amplify the power of the RF signal, and the power amplifier is not stable enough, when the terminal is used as a transmitter and the comprehensive test instrument is used as a receiver to transmit the RF signal through the current tested path, the transmission power fed back by the terminal through the coupler CPL is used as the first transmission power or the second transmission power. This can prevent the instability of the power amplifier from affecting the final RF power test results.
[0065] It should be clear that logical conflicts only exist between different RF channels that can work at the same time. For example, multiple TXs and TDD (time division duplex) TRXs cannot work at the same time, so there is no need to verify logical conflicts. When the current tested channel and its interference channel are opened at the same time, the RF transceiver needs to be switched to a single-master single-sub state, that is, the RF transceiver only receives RF signals on the current tested channel or only transmits RF signals through the current tested channel, and does not receive or send RF signals on the interference channel.
[0066] In actual applications, the specific combination of the current tested path and its interference path is different in different scenarios to meet different test requirements. The following will provide three specific application examples based on the above test method:
[0067] (1) Logical conflict test between TRXs. The test method includes:
[0068] Select at least one transmitting path TX and at least one receiving path RX that can work simultaneously from the radio frequency paths provided by the terminal to form a path set;
[0069] Each radio frequency path in the path set is sequentially used as a current tested path to perform a multi-path test, and in each multi-path test, the remaining radio frequency paths in the path set except the current tested path are used as interference paths;
[0070] According to the multi-path test results of each RF path in the path set, it is determined whether there is a conflict in the logical configuration between the TRXs.
[0071] (2) Logical conflict test between MIMOs. The test method includes:
[0072] Select at least two radio frequency paths based on MIMO technology that can work simultaneously from the radio frequency paths provided by the terminal to form a path set;
[0073] Each radio frequency path in the path set is sequentially used as a current tested path to perform a multi-path test, and in each multi-path test, the remaining radio frequency paths in the path set except the current tested path are used as interference paths;
[0074] According to the multi-path test results of each radio frequency path in the path set, it is determined whether there is a conflict in the logical configuration between MIMOs.
[0075] (3) Logical conflict test between channels (BAND), the test method includes:
[0076] Select at least two radio frequency paths that can simultaneously work on different channels (such as B1 and B41) from the radio frequency paths provided by the terminal to form a path set;
[0077] Each radio frequency path in the path set is sequentially used as a current tested path to perform a multi-path test, and in each multi-path test, the remaining radio frequency paths in the path set except the current tested path are used as interference paths;
[0078] According to the multi-path test results of each radio frequency path in the path set, it is determined whether there is a conflict in the logical configurations between the channels.
[0079] In summary, based on the aforementioned multi-channel RF testing method, the embodiment of the present invention can further realize logical conflict detection between TRXs, between MIMOs, and between channels, is suitable for various application scenarios, ensures the accuracy of the RF path logical configuration in each scenario, and improves the user experience.
[0080] To make it easier to understand, an example is provided below. Figure 3 It is a conventional RF system inside a mobile phone, which includes a RF transceiver and four RF antennas (ANT0, ANT1, ANT2, ANT3), forming multiple RF paths. Figure 2 As shown in the example, the RF path test method includes:
[0081] Single channel test of each RF channel: Open each RF channel such as B1TX, B1PRX, B41DRXMIMO separately to verify whether the logical configuration of each RF channel is correct;
[0082] Logical conflict test between TRX: You can open the three channels of B1TX, B1PRX and B1DRX at the same time. After connecting the mobile phone to the comprehensive test instrument, keep the three channels open and test them three times. If the results are all as expected, there is no logical conflict between B1 TX / RX.
[0083] Logical conflict test between MIMOs: You can open four channels, B41PRX, B41PRXMIMO, B41DRX and B41DRXMIMO, to test logical conflicts at the same time, and then open B41TX and two MIMO channels. If the test results are in line with expectations, there is no logical conflict between the MIMO channels.
[0084] The conflict test between each BAND is mainly to verify whether the inter-band CA and dual-SIM dual-standby are connected normally. For example, B1+41CA opens all receiving paths of B1 and B41 at the same time, and the tests are carried out in turn to analyze the results. If the test results of all bands are PASS, it proves that there is no logical conflict in the dual-SIM dual-standby.
[0085] Among them, CA, or carrier aggregation, supports multiple LTE carriers at the same time, so that a higher transmission rate can be achieved to meet the user's requirements for speed. Inter-band CA refers to when two or more different carriers are in different frequency bands, that is, a combination of different bands. Dual-SIM dual standby means that the two SIM cards installed in the mobile phone can be used at the same time, and the two cards do not interfere with each other. The two cards work in different frequency bands.
[0086] To ensure the accuracy of all logic, you can follow the product manual and traverse the above four situations in turn according to the band information supported by the mobile phone.
[0087] In summary, the terminal radio frequency path testing method provided by the embodiment of the present invention has the following advantages:
[0088] The non-signaling test of this embodiment can be realized automatically, which optimizes the test process and is easy to promote;
[0089] It supplements the current gaps in the industry's non-signaling test of logical conflict testing between TRXs, between MIMO channels, and between channels, ensures the accuracy of the logical configuration of the RF channel, and improves user experience;
[0090] This method is applicable to multiple platforms because each platform supports the forced sending / receiving function. This method uses non-signaling to test the channel logic supported by the signaling standard, and only needs to call the MIPI and GPIO logic of the signaling multi-channel.
[0091] See also Figure 4 The embodiment of the present invention further provides a terminal radio frequency path testing system, including:
[0092] The terminal includes a radio frequency transceiver and at least one radio frequency antenna, wherein the radio frequency transceiver is connected with each radio frequency antenna to form a plurality of radio frequency paths;
[0093] The comprehensive measuring instrument is connected to the RF antenna by radio frequency and is used to switch to the transmitter state or the receiver state according to the instruction;
[0094] The radio frequency path test device is connected to the terminal through a USB cable and to the comprehensive testing instrument through a network cable, and is used to control the terminal and the comprehensive testing instrument to perform a multi-path radio frequency test on the current tested path selected from multiple radio frequency paths: first, the terminal is controlled to simultaneously open the current tested path and at least one corresponding interference path, and other radio frequency paths are closed; one of the terminal and the comprehensive testing instrument is controlled to act as a transmitter and the other as a receiver to transmit radio frequency signals through the current tested path, a first transmission power and a first reception power at both ends of the current tested path are obtained from the comprehensive testing instrument and the terminal, and whether the logic configuration of the current tested path is accurate is judged according to the first power difference between the first transmission power and the first reception power.
[0095] In addition, the RF path test device is also used to perform a single-path RF test on the current path under test: only the current path under test is opened, and other RF paths except the current path under test are closed; the RF transceiver is controlled to transmit RF signals between the current path under test and the comprehensive testing instrument to obtain the second transmission power and the second reception power at both ends of the current path under test; and according to the second power difference between the second transmission power and the second reception power, it is determined whether the logical configuration of the current path under test is incorrect.
[0096] The radio frequency path test device, when judging whether the logic configuration of the current tested path is accurate, is specifically used to: if the logic configuration of the current tested path itself is correct and the first power difference exceeds the first threshold, it is determined that there is a conflict in the logic configuration between the interference path and the current tested path; otherwise, it is determined that there is no conflict in the logic configuration between the interference path and the current tested path.
[0097] In fact, each RF antenna of the terminal can be directly connected to its corresponding comprehensive testing instrument separately, but in order to save testing costs, multiple RF antennas can be optionally connected to the same comprehensive testing instrument through an octa-power device.
