[0060] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0061] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0062] In the 5G (New Radio, NR) system, when an uplink data transmission exception occurs, in order to accurately determine whether the error is caused by the baseband-generated data stream or the RF transmission, a feasible solution is to locate the transmission exception by analyzing the original in-phase quadrature (IQ) data of the terminal.

[0063] Specifically, in one implementation, the terminal is connected to an FPGA-based IQ data acquisition board through a third-party instrument or the terminal itself is directly connected to the IQ data acquisition board, which monitors the uplink data transmission of the terminal in real time and saves the original IQ data, so that when an uplink data transmission abnormality occurs, the cause of the transmission abnormality can be located through the saved original IQ data. However, the IQ data acquisition board is expensive and inconvenient to carry. Using the IQ data acquisition board will not only greatly increase the cost of the equipment, but also, due to the application scenarios of mobile terminals, it is impossible for mobile terminals to be connected to third-party instruments or equipped with IQ data acquisition boards at any time.

[0064] In response to the above problems, an embodiment of the present application proposes a communication data processing method, which does not use an external IQ data acquisition board, but instead monitors the sending of uplink data based on the mobile terminal's own hardware, saves the sent uplink data, and when an uplink data sending abnormality occurs, locates the cause of the sending abnormality based on the uplink data saved by the mobile terminal itself.

[0065] Specifically, the uplink data transmission rate of the mobile terminal in the NR system is as high as 375 mbps. Therefore, the mobile terminal does not have enough storage space to save the original IQ data for a long time. However, in the application scenario of locating the transmission anomaly, when the transmission anomaly occurs, locating the transmission anomaly does not require the original IQ data for a long time, but only the uplink data of the time node where the transmission anomaly occurs. Therefore, in the scheme of the embodiment of the present application, the NR system mobile terminal uses a small storage space to store the transmitted uplink data, and when there is no uplink transmission anomaly, the uplink data stored in the storage space is continuously updated with the latest uplink data; when an uplink transmission anomaly occurs, the uplink transmission anomaly is located based on all stored uplink data.

[0066] Figure 1 FIG. 1 is a schematic diagram of a mobile terminal framework according to an embodiment of the present application. Figure 1 As shown, the mobile terminal 100 includes a memory 110, a data storage module 120 and a monitoring module 130. A fixed-size uplink data storage area 111 is divided in the memory 110. The memory 110 can be any storage device on the mobile terminal 100 with available storage space, for example, the memory of the mobile terminal 100 (for example, Double Data Rate SDRAM (DDR)), the hard disk of the mobile terminal 100, or a local storage card (for example, an embedded multimedia card (EMMC)).

[0067] Specifically, considering that locating a sending anomaly only requires the uplink data of the time node where the sending anomaly occurs, when no sending anomaly occurs, the uplink data does not need to be stored for a long time; and, if the latest uplink data is written to the uplink data storage area 111, then the data write rate of the uplink data storage area 111 will be consistent with the rate at which the mobile terminal 100 sends uplink data. Therefore, in one embodiment of the present application, the memory 110 is the internal memory of the mobile terminal 100 (for example, DDR).

[0068] Further, in one embodiment, the size of the uplink data storage area 111 is determined by the amount of data required to locate the uplink transmission anomaly. Specifically, in one implementation, the size of the uplink data storage area 111 is equal to the total amount of IQ data required to locate the uplink transmission anomaly. In another embodiment, considering data redundancy, the size of the uplink data storage area 111 is greater than the total amount of IQ data required to locate the uplink transmission anomaly.

[0069] Figure 2 FIG. 1 is a flow chart of a communication data processing method according to an embodiment of the present application. In the process of uplink data transmission by the mobile terminal 100, the mobile terminal 100 executes the following Figure 2 The following steps are shown:

[0070] S200, the data storage module 120 obtains the uplink data (original uplink IQ data) currently sent by the mobile terminal 100;

[0071] S210 , the data storage module 120 stores the uplink data currently sent by the mobile terminal 100 in the uplink data storage area 111 .

[0072] Since the size of the uplink data storage area 111 is fixed, the uplink data storage area 111 will soon be filled with uplink data when the data storage module 120 saves the uplink data currently sent by the mobile terminal 100 to the uplink data storage area 111. Since locating the uplink transmission anomaly does not require long-term original IQ data, only the uplink data of the time node where the transmission anomaly occurs is required, therefore, in S210, when there is no storage space in the uplink data storage area 111, the data storage module 120 overwrites the latest uplink data with the old uplink data, thereby ensuring that the latest uplink data can always be saved.

[0073] Specifically, in one implementation, the uplink data storage area 111 is divided into a plurality of cache blocks (e.g., cache block 1 to cache block N). After the mobile terminal 100 starts to send uplink data, the data storage module 120 writes the uplink data sent by the mobile terminal 100 into cache blocks 1 to cache blocks N in sequence according to the order of numbers 1-N. When the writing of a cache block is completed (e.g., the data on the cache block is cleared before writing, and when the cache block is full, the writing of the cache block is completed), the latest uplink data is written into the next cache block. When the writing of cache block N is completed, the data storage module 120 writes the latest uplink data into cache block 1, and then continues to save the uplink data sent by the mobile terminal 100 into cache blocks 1 to cache blocks N in sequence according to the data numbered 1-n. Thus, the cycle of cache blocks 1 to cache blocks N is continuously repeated to ensure that the latest uplink data can always be saved into the uplink data storage area 111.

[0074] Furthermore, in order to quickly and accurately locate the uplink transmission anomaly in the future, in one implementation of S210, the data storage module 120 saves the latest uplink data to the uplink data storage area 111, and also saves the relevant device parameters for sending the uplink data (for example, the various input parameters of accelerators such as the system bus (Advanced High performance Bus, AHB) control registers that are ultimately configured, including the code block size of the uplink physical shared channel (Physical Uplink Shared Channel, PUSCH), the modulation order, the number of Inverse Fast Fourier Transform (IFFT) points, the initial concentration (CINIT) parameters related to the production of the demodulation reference signal (DMRS) sequence, etc.) to the uplink data storage area 111.

[0075] For example, in an implementation of S210 , the data storage module 120 packages the uplink data and the accelerator parameters into an uplink data packet (the data packet structure is shown in Table 1), and stores the uplink data packet in the uplink data storage area 111 .

[0076] Packet Header Accelerator parameters IQ Data Check code

[0077] Table 1

[0078] In Table 1, the data packet header is used to identify that this data packet is an uplink data packet used to locate uplink transmission anomalies; the accelerator parameters are parameters of related devices used by the mobile terminal 100 to send uplink data; the IQ data is the uplink data sent by the mobile terminal 100; the check code is the check code of the uplink data packet, for example, a cyclic redundancy check (CRC).

[0079] Furthermore, in order to facilitate storage of uplink data, in one embodiment, the size of a cache block in the uplink data storage area 111 is the size of an uplink data packet.

[0080] Figure 3 FIG. 1 is a partial flow chart of a communication data processing method according to an embodiment of the present application. The uplink data storage area 111 includes N cache blocks numbered 1 to N. In an implementation of S200 and S210, the data storage module 120 executes the following steps: Figure 3 The following steps are shown.

[0081] S300, obtaining uplink data (original uplink IQ data) currently sent by the mobile terminal 100;

[0082] S311, packing the uplink data and accelerator parameters into an uplink data packet;

[0083] S312, writing the uplink data packet into the cache block numbered n, where the initial value of n is 1;

[0084] S313, determine whether the current value of n is N, and determine whether n == N?;

[0085] If not equal, S314, let the value of n be incremented by 1, and let n=n+1;

[0086] If they are equal, S315, set the value of n to 1, set n = 1;

[0087] Return to S300.

[0088] Based on the execution of S200 and S210, when an uplink transmission anomaly occurs in the mobile terminal 100, the uplink transmission anomaly can be located according to the uplink data stored in the uplink data storage area 111. However, in some application scenarios, when an uplink transmission anomaly occurs, the transmission of the uplink data does not stop. In this case, if the latest uplink data continues to be stored in the uplink data storage area 111, the new uplink data will overwrite the uplink data when the uplink transmission anomaly occurs, resulting in the inability to locate the uplink transmission anomaly. If the uplink transmission anomaly occurs, the storage of the uplink data is suspended, and the latest uplink data is continued to be stored in the uplink data storage area 111 after the uplink transmission anomaly is located, which will result in the omission of the uplink data. At this time, if a new uplink transmission anomaly occurs during the process of locating the uplink transmission anomaly, the new uplink transmission anomaly cannot be located.

[0089] In view of the above problems, in the solution of the embodiment of the present application, during the process of the mobile terminal 100 sending uplink data, the latest uplink data is always saved synchronously (S200 and S210 are always executed in a loop); at the same time, during the process of the mobile terminal 100 sending uplink data, it is monitored whether an uplink transmission anomaly occurs. When an uplink transmission anomaly occurs, the saving of the latest uplink data is not interrupted / paused (the loop execution of S200 and S210 is maintained), but the uplink data in the current uplink data storage area 111 is output, so that the uplink transmission anomaly that has occurred can be located based on the output data later. Before and after the uplink data in the uplink data storage area 111 is output, the uplink data in the uplink data storage area 111 is always kept in synchronization with the uplink data sent by the mobile terminal 100.

[0090] Furthermore, in one implementation, the acquisition and storage of uplink data and the detection of uplink transmission anomalies are performed in a loop. Figure 2As shown, in a data storage cycle, uplink data is acquired (S200) and stored (S210) in sequence, and after S210, S220 is executed, and the monitoring module 130 determines whether an uplink transmission abnormality occurs.

[0091] If no uplink transmission abnormality occurs, the process returns to S200 and executes the next data saving cycle to continue saving the latest uplink data.

[0092] If an uplink transmission anomaly occurs, S230 is executed, and the monitoring module 130 outputs the uplink data in the uplink data storage area 111. After S230, the process returns to S200, and the next data storage cycle is executed to continue to store the latest uplink data.

[0093] Further, in another implementation, the acquisition and storage of uplink data are executed cyclically, and the cycle is executed in parallel with the detection step of uplink transmission anomaly. That is, in one data storage cycle, the acquisition of uplink data (S200) and the storage of uplink data (S210) are performed in sequence. The data storage cycle is executed cyclically, and, during the cycle of the data storage cycle, S220 and S230 are executed synchronously.

[0094] Further, in one implementation, in S230 , all data in the uplink data storage area 111 are output.

[0095] In another implementation, in S230, the amount of uplink data output is determined by the need to locate the uplink transmission anomaly. For example, locating the uplink transmission anomaly requires 4 uplink data packets, assuming that the current uplink data storage area 111 is configured with 4 cache blocks, each cache block is used to store 1 uplink data packet. Then in S230, all data in the uplink data storage area 111 are output. For another example, locating the uplink transmission anomaly requires 4 uplink data packets, assuming that the current uplink data storage area 111 is configured with 6 cache blocks in consideration of data redundancy, then in S230, the data in the 4 cache blocks of the most recently written data in the uplink data storage area 111 are output.

[0096] According to the method of the embodiment of the present application, the uplink data can be saved when sending the uplink data and the uplink data that can effectively locate the anomaly can be output when an uplink sending anomaly occurs; the implementation of the method of the embodiment of the present application requires less storage capacity, consumes less processor computing power, has low hardware cost, and is easy to carry and operate.

[0097] Further, in one embodiment, in S230, the uplink data in the uplink data storage area 111 is sent to a positioning device, and the positioning device is used to locate the uplink transmission anomaly according to the uplink data. For example, in S230, the uplink data in the uplink data storage area 111 is sent to a terminal device (e.g., a personal computer (PC)) installed with uplink transmission anomaly positioning software, and the uplink transmission anomaly is located by a data processing device.

[0098] Specifically, in one embodiment, the mobile terminal includes an application processor (AP) for processing application data and implementing application functions, and a communication processor (CP) for processing communication data and implementing communication functions (e.g., 5G wireless communication). The data storage module and the monitoring module of the mobile terminal are constructed based on the AP and CP of the mobile terminal.

[0099] Figure 4a FIG. 1 is a schematic diagram of a mobile terminal framework according to an embodiment of the present application. Figure 4a As shown, the mobile terminal 400 includes a memory (DDR410), an application processor (AP420) and a communication processor (CP430). The DDR410 is divided into an uplink data storage area 411 of a fixed size.

[0100] Figure 4b FIG. 4 is a flow chart of a communication data processing method according to an embodiment of the present application. When the mobile terminal 400 sends uplink data based on the CP 430, the mobile terminal 400 executes the following Figure 4b The following steps are shown.

[0101] S400, CP430 obtains the currently transmitted uplink data (IQ data); specifically, CP430 is integrated with a data capture module capable of capturing communication data. When the mobile terminal 400 transmits uplink data based on CP430, CP430 captures the currently transmitted uplink data (IQ data) through the data capture module.

[0102] S410, CP430 packages the captured uplink data and accelerator parameters into an uplink data packet (refer to S210).

[0103] S411, CP430 saves the uplink data packet to the uplink data storage area 411 (refer to S210).

[0104] S420 and CP430 detect whether an abnormality occurs in uplink transmission.

[0105] When CP430 does not detect an abnormality in uplink transmission, it returns to S400.

[0106] When CP430 detects an abnormality in uplink transmission, S421, CP430 triggers an abnormality assertion (Assert).

[0107] S430, when the AP 420 detects that the abnormal Assert is triggered, all the data in the uplink data storage area 411 are sent to the personal computer (PC 401) (for example, the data is sent to the PC 401 via a USB or wireless connection).

[0108] After S430, PC401 executes S440 to parse the uplink data packet and obtain accelerator parameters and IQ data;

[0109] S450 and PC401 analyze accelerator parameters and IQ data to locate uplink transmission anomalies.

[0110] In the above process, since CP430 can only generate an uplink data packet after capturing the IQ data required for an uplink data packet, there is a time interval between the generation of two adjacent uplink data packets. Therefore, after executing S411 (after saving an uplink data packet), S420, S421 and S430 are executed. When the total execution time of S420, S421 and S430 is less than the time interval between the generation of two adjacent uplink data packets, the uplink data can be captured and saved uninterruptedly. Therefore, if Figure 4b As shown, in one implementation, after S430 , CP 430 returns to continue executing S400 .

[0111] Alternatively, in another implementation, after S421, CP430 returns to continue executing S400. Since there is a time interval between the generation of two adjacent uplink data packets, there is a time interval between after S421 and the next execution of S411. When S430 is executed within this time interval, the next execution of S411 after S421 will not affect the execution of S430 after S421.

[0112] Furthermore, in one embodiment, the mobile terminal 100 locates the uplink transmission anomaly that occurs in itself. Specifically, in S230, all uplink data in the uplink data storage area 111 are sent to the uplink transmission anomaly locating module of the mobile terminal 100 for locating.

[0113] Specifically, in one embodiment, the mobile terminal includes an application processor (AP) for processing application data and implementing application functions, and a communication processor (CP) for processing communication data and implementing communication functions (e.g., 5G wireless communication). The data storage module, monitoring module, and uplink transmission abnormality positioning module of the mobile terminal are constructed based on the AP and CP of the mobile terminal.

[0114] Figure 5a FIG. 1 is a schematic diagram of a mobile terminal framework according to an embodiment of the present application. Figure 5a As shown, the mobile terminal 500 includes a memory (DDR510), an application processor (AP520) and a communication processor (CP530). The DDR510 is divided into an uplink data storage area 511 of a fixed size.

[0115] Figure 5b FIG. 5 is a flow chart of a communication data processing method according to an embodiment of the present application. When the mobile terminal 500 sends uplink data based on CP530, the mobile terminal 500 executes the following Figure 5b The following steps are shown.

[0116] S500, CP530 obtains the uplink data (IQ data) currently being sent; refer to S400.

[0117] S510, CP530 packages the captured uplink data and accelerator parameters into an uplink data packet (refer to S410).

[0118] S511, CP530 saves the uplink data packet to the uplink data storage area 411 (refer to S411).

[0119] S520 and CP530 detect whether an abnormality occurs in uplink transmission.

[0120] When CP530 does not detect an abnormality in uplink transmission, it returns to S500.

[0121] When CP530 detects an abnormality in uplink transmission, S521, CP530 triggers an abnormality assertion (Assert).

[0122] S530 , when the AP 520 detects that the abnormal Assert is triggered, it reads all data in the uplink data storage area 411 .
