Description

TECHNICAL FIELD

[0001] The present application relates to the terminal field, and in particular to a log generation method, a terminal device and a readable storage medium. BACKGROUND

[0002] A terminal device generates event records when working, which are referred to as logs. The logs record time information, user and related operation descriptions, such as application logs, security logs or system logs, etc. In the development and operation process, logs are needed to help developers troubleshoot problems. With the development of communication systems, the complexity of terminal devices is increasing, and thus the number of logs generated by terminal devices when working is increasing. However, the memory capacity of terminal devices is limited, so the more logs generated by terminal devices per unit time, the higher the possibility that the logs are overwritten in the memory of the terminal device in a short time. In this case, key logs may be lost in a short time, which is not conducive to people positioning terminal device problems or performing other processing according to the key logs. SUMMARY

[0003] The present application provides a log generation method, a terminal device and a readable storage medium. The scheme provided by the present application can save memory resources in the process of storing logs, and avoid the logs being overwritten in the memory of the terminal device in a short time, that is, the problem that the logs needed for positioning terminal device problems or performing other processing are overwritten in a short time can be avoided.

[0004] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0005] In a first aspect, a log generation method is provided, which is applied to a terminal device. The terminal device includes a first processing module, a second processing module and a storage module. The method includes: the first processing module generates a first log record based on first time information from the second processing module, the first log record including the first time information, the first time information being used to determine an absolute time for generating a second log record in combination with second time information, the second log record being generated by the first processing module and stored in the storage module, the second log record including the second time information; and the storage module stores the first log record.

[0006] The log record generated by the terminal device is indispensable when positioning problems of the terminal device, and the absolute time for generating the log record needs to be recorded in the log record, for example, the year / month / day / hour / minute / second information for generating the log record. The log record with the absolute time often occupies a large amount of memory resources.

[0007] Based on this, the scheme provided in the application records the second time information in the generation of a certain log record (for example, the second log record), for example, the second time information can be the time information generated by the local clock, and records the first time information for determining the absolute time of generating the second log record in another log record (for example, the first log record), for example, the first time information can include information for determining the year / month / day of generating the second log record. Since the first time information can determine the absolute time of generating the multiple second log records corresponding to the same first time information in combination with the multiple second time information, the scheme provided in the application can store the multiple second log records recording the second time information and the first log record when storing the log subsequently. Compared with storing the multiple second log records, each of which records the absolute time of generating the second log record, the scheme provided in the application can save more memory resources in the process of storing the log.

[0008] In some possible implementation manners, the method further includes: periodically sending, by the second processing module, the first time information to the first processing module.

[0009] Based on the above scheme, the first processing module can periodically generate the first log record according to the first time information, so as to avoid that the absolute time of generating the second log record that has not been covered cannot be determined after the first log record generated earlier is covered in the memory.

[0010] In some possible implementation manners, the sending period of the first time information is determined based on pre-configuration.

[0011] In some possible implementation manners, the terminal device further includes a third processing module, and the method further includes: obtaining, by the third processing module, the first log record and the second log record from the storage module; and generating, by the third processing module, a third log record based on the first log record and the second log record, the third log record including the absolute time of generating the second log record and all or part of the content of the second log record except the second time information.

[0012] Based on the above scheme, if the third processing module needs the second log record when positioning the problem, the third processing module can generate the third log record based on the first log record and the second log record in the storage module, the third log record including the absolute time of generating the second log record and all or part of the information of the second log record except the time information. That is, after generating the third log record, the third processing module can directly position or troubleshoot the problem according to the third log record.

[0013] In some possible implementation manners, the storage module stores the third log record, and a log file in which the third log record is located does not contain the first log record and the second log record.

[0014] Based on the above scheme, the log file in which the third log record is located is different from the log file in which the first log record and / or the second log record is located. The first log record and the second log record can be in the same log file or in different log files, which is not limited in the present application.

[0015] In some possible implementation manners, the first processing module is a radio frequency chip for amplifying the power of the radio frequency signal, or the first processing module is a chip for controlling whether to radiate the radio frequency signal.

[0016] In some possible implementation manners, the second processing module is an application chip.

[0017] In a second aspect, a method for generating a log is provided, and the method is applied to a first device. The first device includes a processing module and a storage module. The method includes: determining, by the processing module, whether a preset condition is met before generating a fourth log record corresponding to a first time unit, the fourth log record including information representing a communication condition between the first device and a second device in the first time unit; and generating, by the processing module, the fourth log record and storing, by the storage module, the fourth log record in a case where the preset condition is met.

[0018] Based on the above scheme, the processing module needs to determine whether the preset condition is met before generating the fourth log record. The fourth log record is generated and stored only in the case where the preset condition is met, that is, the fourth log record is not generated in the case where the preset condition is not met. Therefore, the scheme provided in the present application can reduce the number of generated fourth log records by condition determination, thereby reducing the memory space of the first device occupied by the fourth log record, avoiding the problem that the log is covered in the memory of the first device in a short time, and thereby avoiding the problem that the key log record required for positioning the first device problem or other processing is covered in a short time.

[0019] In some possible implementation manners, the preset condition includes at least one of the following: a communication signal energy between the first device and the second device is less than or equal to a first threshold in the first time unit; a packet error rate SER of a communication link between the first device and the second device is less than or equal to a second threshold in the first time unit; a reference signal received power RSRP corresponding to the communication link between the first device and the second device does not jump in the first time unit; a sending module or a receiving module of the first device is in a working mode in the first time unit; the fourth log record includes only content related to uplink transmission when the first time unit is an uplink transmission resource; and the fourth log record includes only content related to downlink transmission when the first time unit is a downlink transmission resource.

[0020] In some possible implementation manners, the fourth log record is a log record related to the first device as a sender, and the preset condition is satisfied when any one of the following conditions is met: a maximum transmission power between the first device and the second device is less than or equal to a first threshold in the first time unit; a transmission module of the first device is in an operating mode in the first time unit; or the first time unit is an uplink transmission resource.

[0021] In some possible implementation manners, the fourth log record is a log record related to the first device as a receiver, and the preset condition is satisfied when any one of the following conditions is met: a received signal strength indication (RSSI) between the first device and the second device is less than or equal to a second threshold in the first time unit; a service experience rate (SER) of a packet transmitted between the first device and the second device is less than or equal to the second threshold in the first time unit; a reference signal received power (RSRP) corresponding to a communication link between the first device and the second device does not jump in the first time unit; a receiving module of the first device is in an operating mode in the first time unit; or the first time unit is a downlink transmission resource.

[0022] In some possible implementation manners, the fourth log record includes information representing: a subscriber identity module (SIM) identifier, a time slot number, a system frame number, a subcarrier spacing, a time domain symbol index, a maximum transmission power, and a target transmission power.

[0023] In some possible implementation manners, the fourth log record includes information representing: a subscriber identity module (SIM) identifier, a time slot number, a system frame number, a subcarrier spacing, a time domain symbol index, a maximum transmission power, and a target transmission power.

[0024] In some possible implementation manners, the processing module is a cellular communication baseband chip.

[0037] The technical solutions in the present application will be described below with reference to the accompanying drawings.

[0040] The method for generating a log provided by the embodiments of the present application can be applied to a mobile phone, a tablet computer, a notebook computer, a palm computer, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), a smart home, and the like, which can generate a log. The embodiments of the present application do not limit the specific type of the terminal device.

[0041] The hardware structure of the terminal device 100 for implementing the above method is described below. For example, Figure 1 A hardware structure of the terminal device 100 is shown. The terminal device 100 can include a processor 110, an external memory interface 120, an internal memory 121, a universal serial bus (USB) interface 130, a charging management module 140, a power management module 141, a battery 142, and a transceiver 150.

[0042] It can be understood that the structure shown in the embodiments of the present application does not constitute a specific limitation on the terminal device 100. In other embodiments of the present application, the terminal device 100 can include more or fewer components than shown, or combine certain components, or split certain components, or different component arrangements. The components shown can be implemented in hardware, software, or a combination of software and hardware.

[0043] For example, when the terminal device 100 is a mobile phone or a tablet computer, it can include all the components shown in the figure, or only include some of the components shown in the figure.

[0044] The processor 110 can include one or more processing units, for example: the processor 110 can include an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural-network processing unit (NPU), etc. Different processing units can be independent devices or integrated in one or more processors.

[0045] The controller can generate operation control signals according to the instruction operation code and the timing signal, complete the control of fetching and executing instructions.

[0046] The processor 110 can also be provided with a memory for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory can save instructions or data that have just been used or are used repeatedly by the processor 110. If the processor 110 needs to use the instructions or data again, it can directly call from the memory. This avoids repeated access and reduces the waiting time of the processor 110, thereby improving the efficiency of the system.

[0047] In some embodiments, the processor 110 can include one or more interfaces. The interfaces can include an inter-integrated circuit (I2C) interface, an inter-integrated circuit sound (I2S) interface, a pulse code modulation (PCM) interface, a universal asynchronous receiver / transmitter (UART) interface, a mobile industry processor interface (MIPI), a general-purpose input / output (GPIO) interface, a subscriber identity module (SIM) interface, and / or a universal serial bus (USB) interface, etc.

[0048] It can be understood that the interface connection relationship between the modules shown in the embodiments of the present application is only illustrative and does not constitute a limitation on the structure of the terminal device 100. In some other embodiments of the present application, the terminal device 100 can also use different interface connection modes or a combination of multiple interface connection modes in the above embodiments.

[0049] The charging management module 140 is configured to receive charging input from a charger. The charger can be a wireless charger or a wired charger. In some wired charging embodiments, the charging management module 140 can receive charging input from a wired charger through the USB interface 130. In addition to charging, the USB interface can also be used to open the USB debugging switch or in other words, to open the USB debugging mode. In some wireless charging embodiments, the charging management module 140 can receive wireless charging input through the wireless charging coil of the terminal device 100. The charging management module 140 can charge the battery 142 and also supply power to the terminal device through the power management module 141.

[0050] The power management module 141 is configured to connect the battery 142, the charging management module 140 and the processor 110. The power management module 141 receives input from the battery 142 and / or the charging management module 140 to supply power to the processor 110, the internal memory 121 and the like. In some other embodiments, the power management module 141 can also be arranged in the processor 110. In some other embodiments, the power management module 141 and the charging management module 140 can also be arranged in the same device.

[0051] The transceiver 150 is configured to transmit data or signaling and the like to other devices outside the terminal device 100 or to receive data or signaling and the like from other devices outside the terminal device 100.

[0052] The external memory interface 120 can be configured to connect an external memory card, such as a micro (Micro) memory card (secured digital memory card, SD), to expand the storage capacity of the terminal device 100. The external memory card communicates with the processor 110 through the external memory interface 120 to realize data storage function.

[0053] Internal memory 121 can be used to store computer executable program code, which includes instructions. Internal memory 121 may include a program storage area and a data storage area. The program storage area may store the operating system, applications required for at least one function, etc. The data storage area may store data created during the use of terminal device 100, such as logs. In addition, internal memory 121 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, universal flash storage (UFS), etc. Processor 110 executes various functional applications and data processing of terminal device 100 by running instructions stored in internal memory 121 and / or instructions stored in memory disposed in the processor.

[0054] In practical application scenarios, the operating system of the terminal device 100 may include, but is not limited to, Symbian, Android, Windows, macOS, iOS, Blackberry, HarmonyOS, and other operating systems. This application does not impose any limitations on the operating system of the terminal device.

[0055] Before describing the solutions provided in the embodiments of this application, the terms involved in this application will be explained.

[0056] Logs can be understood in a broad sense, such as event records generated by terminal devices or chips during operation, including log records, log files, log content, log data, etc.

[0057] Log recording: A log record is generated by a terminal device or chip for each operation performed, and the log record may include one or more lines of content. One or more log records may be stored in a log file, which is stored in the terminal device's memory. Additionally, log records may also be called log content, log data, etc. This application does not limit the name of log records and uses "log record" as a unified description.

[0058] Figure 2 This is a schematic diagram of the air interface frame structure for new radio (NR) communication provided in this application embodiment.

[0059] For example, such as Figure 2 As shown, the duration T of a wireless frame f = 10 milliseconds (ms), the duration T of a time slot slot=0.5ms, one subframe consists of two time slots. When the terminal device is operating in 5G NR cellular communication mode, a maintenance log is generated in each time slot.

[0060] It should be noted that the temporal granularity of generating dimension monitoring logs can be predefined. In the example above, the temporal granularity of generating dimension monitoring logs is time slot, and this application does not impose any restrictions on this.

[0061] Logs generated by terminal devices can be divided into event logs and statistical logs. Event logs are generated only when an event occurs, such as when the terminal device and the base station complete a radio resource control (RRC) connection, or when the terminal device initiates a call. Statistical logs are generated when the terminal device periodically checks a certain function / parameter, such as when the terminal device checks the cellular communication quality.

[0062] During the Beta testing phase of terminal devices, logs were captured to identify issues. NR (Radio Frequency) monitoring logs accounted for a significant portion, reaching 20%. NR monitoring logs characterize the signal energy of cellular communication on the terminal device, and each time-domain granularity (e.g., subframe) generates an NR monitoring log. These logs, such as those characterizing signal reception or transmission energy, are crucial for pinpointing 5G signal loss issues. Since monitoring communication quality is essential, generating NR monitoring logs is unavoidable. However, the limited storage space and the problem of logs being overwritten quickly can be addressed by streamlining these logs.

[0063] In view of this, this application proposes a log generation scheme that can reduce the amount of maintenance logs generated, save more memory resources in the subsequent log storage process, and avoid logs being overwritten in the terminal device's memory in a short time, thereby avoiding the problem that critical logs required for locating terminal device problems or performing other processing are overwritten in a short time.

[0064] Figure 3 This is a flowchart illustrating a method for generating logs provided in an embodiment of this application.

[0065] like Figure 3 The method 300 shown can be used in a first device, which includes a processing module and a storage module. Method 300 includes the following steps:

[0066] S301, before generating the log record #1 corresponding to the first time unit, the processing module determines whether a preset condition is met, the log record #1 includes information representing a communication condition between the first device and the second device on the first time unit, the first device is a terminal device, and the second device is another terminal device or a network device.

[0067] The network device can manage transmission resources, provide access services for user equipment, and complete the forwarding of user equipment data between user equipment and a core network. The network device in the present application includes but is not limited to: an evolved Node B (eNB), a radio network controller (RNC), a Node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home evolved NodeB (HeNB) or a home Node B (HNB), a baseband unit (BBU), an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP) or a transmission and reception point (TRP), and the like. It can also be a gNB or a transmission point (TRP or TP) in a 5G NR system, one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node constituting a gNB or a transmission point, such as a baseband unit (BBU) or a distributed unit (DU), or a base station in a future communication system, and the like.

[0068] For example, the time domain granularity of the log record #1 (corresponding to the fourth log record in the invention) generated by the first device configured by the network device is a time slot, and before generating the log record #1 corresponding to each time slot, the first device needs to determine whether the preset condition is met. The log record #1 is, for example, the measurement log mentioned above. At this time, the above-mentioned first time unit can be a certain time slot. If the time domain granularity of the log record #1 generated by the first device configured by the network device is a subframe, the above-mentioned first time unit can be a certain subframe, and so on. The communication condition can be represented by parameters such as communication signal energy, symbol error rate (SER), reference signal receiving power (RSRP), and the like.

[0069] In a possible implementation, the preset condition comprises at least one of the following: a communication signal energy between the first device and the second device is less than or equal to a first threshold in a first time unit; a SER of a packet transmitted between the first device and the second device is less than or equal to a second threshold in the first time unit; a RSRP corresponding to a communication link between the first device and the second device does not jump in the first time unit; a sending module or a receiving module of the first device is in a working mode in the first time unit; when the first time unit is an uplink transmission resource, the log record #1 only includes content related to uplink transmission; when the first time unit is a downlink transmission resource, the log record #1 only includes content related to downlink transmission.

[0070] S302, in a case where the preset condition is met, the processing module generates a log record #1, and the storage module stores the log record #1.

[0071] In a possible implementation #1, the log record #1 is a log record related to the first device as a sender, that is, the log record #1 records relevant descriptions of the first device in a sending operation in the first time unit. When the first device is a sender, the receiver can be a network device or another first device, which is not limited in the application. The preset condition is met, including that any one or more of the following is met:

[0072] A maximum sending power between the first device and the second device is less than or equal to a first threshold in the first time unit; a sending module of the first device is in a working mode in the first time unit; or the first time unit is an uplink transmission resource.

[0073] When the log record #1 is a log record related to the first device as a sender, the communication signal energy is, for example, a maximum sending power, and a first threshold corresponding to the maximum sending power is the first threshold. When the log record #1 is a log record related to the first device as a receiver, the communication signal energy is, for example, a received signal strength indication (RSSI), and a first threshold corresponding to the received signal strength indication is a second threshold. The first threshold and the second threshold can be preconfigured or predefined, which is not limited in the application, and the first threshold and the second threshold are different.

[0074] For example, when the log record #1 is a log record related to the first device as a sender, the log record #1 includes information indicating the following content: a subscriber identity module (SIM) identifier, a time slot number, a system frame number, a subcarrier spacing, a symbol index, a maximum sending power, and a target sending power.

[0075] Optionally, when the log record #1 is the log record related to the first device as the sender, the log record #1 further comprises a field indicating any of the following: a timing parameter, a maximum power reduction (MPR), a number of resource blocks (RBs), a sounding reference signal (SRS) index.

[0076] For example, when the log record #1 is the log record related to the first device as the sender, some of the contents in the log record #1 can be generated according to the actual operation performed by the first device, such as a time slot number, a system frame number, a subcarrier spacing, a symbol index, a timing parameter, an RB, an SRS index, etc., some of the contents in the log record #1 can be generated according to a protocol, such as a maximum transmission power, an MPR, etc., and some of the contents in the log record #1 can be generated according to an indication from a network device, such as a target transmission power.

[0077] It should be noted that when the preset condition in the implementation manner #1 is not met, the processing module does not generate the log record #1, or the processing module generates the log record #1 but the storage module does not store the log record #1.

[0078] It can be understood that when any of the preset conditions in the implementation manner #1 is not met, the processing module can not generate the log record #1. Alternatively, when any of the preset conditions in the implementation manner #1 is not met, the processing module can generate the log record #1, but does not write the log record #1 into the buffer, so that the log record #1 will not be written to the storage module. Alternatively, when any of the preset conditions in the implementation manner #1 is not met, the processing module generates the log record #1 and writes the log record #1 into the buffer, and the log record #1 can be filtered in the process of writing from the buffer to the storage module, so that the log record #1 will not be written to the storage module. The present application does not limit the operations of the processing module and the storage module when any of the preset conditions in the implementation manner #1 is not met.

[0079] In example #1, the maximum transmission power between the first device and the second device is greater than a first threshold in a first time unit, or in other words, the maximum transmission power of the first device for transmitting a signal to the second device in the first time unit is greater than the first threshold, at this time, the preset condition is not met, the first threshold is a threshold of the configured maximum transmission power, which can be the value range of the maximum transmission power field in the test log, and the first threshold can be configured by the developer according to the experience value. The preset condition judging manner in example #1 can be in the development stage of the first device.

[0080] Example #2, the transmitting module of the first device is in a turn-off mode (tx off) in the first time unit, or in other words, the transmitting module of the first device does not work in the first time unit, at this time the preset condition is not met. For example, the network device does not schedule the first device to transmit a packet in the first time unit, or the first device is in a frequency measurement process in the first time unit, at this time the transmitting module is in a turn-off mode.

[0081] Example #3, the first time unit is a downlink transmission resource, at this time the preset condition is not met, for example, according to the time division duplexing (TDD) band standard of the 3rd generation partnership project (3GPP), the first time unit is a downlink time slot D. That is, when the first time unit is a downlink time slot D, the first device corresponding to the first time unit is not generated as a sender-related log record.

[0082] Possible implementation #2, the log record #1 is a first device as a receiver-related log record, that is, the log record #1 records the relevant description of the first device when it performs a receiving operation in the first time unit, when the terminal device is a receiver, the sender can be a network device or another terminal device, which is not limited by the present application. The preset condition is met including any one or more of the following:

[0083] The received signal strength indication (RSSI) between the first device and the second device is less than or equal to a second threshold in the first time unit; the SER of the packet transmitted between the first device and the second device is less than or equal to the second threshold in the first time unit; the RSRP of the communication link corresponding to the first device and the second device does not jump in the first time unit; the receiving module of the first device is in a working mode in the first time unit; or, the first time unit is a downlink transmission resource.

[0084] For example, when the log record #1 is a first device as a receiver-related log, the log record #1 includes information indicating the following: SIM card identifier, time slot number, system frame number, subframe number, RSSI.

[0085] Optionally, when the log record #1 is a first device as a receiver-related log record, the log record #1 further includes information indicating the following: timing parameter, carrier index, receiving antenna index, low noise amplifier (LNA) receiving gain (gain) position.

[0086] Exemplarily, when the log record #1 is a log record related to the first device as a receiver, the content in the log record #1 can be generated according to an operation actually performed by the first device, can be generated according to a protocol, or can be generated according to an indication of a network device, and the application does not make any limitation in this regard.

[0087] Exemplarily, the processing module for generating the log record #1 is a cellular communication baseband chip.

[0088] It should be noted that when the preset condition is not met in the implementation manner #2, the processing module does not generate the log record #1, or the processing module generates the log record #1 but the storage module does not store the log record #1.

[0089] The specific implementation when the preset condition is not met can refer to the related description in the implementation manner #1, which will not be described herein again.

[0090] In example #4, the RSSI between the first device and the second device is greater than a second threshold in the first time unit, or in other words, the RSSI of the signal received by the first device in the first time unit is greater than the second threshold, at this time, the preset condition is not met, and the second threshold is a configured threshold of the RSSI, which can be a value range of the RSSI field in the measurement log, and the second threshold can be configured by the developer according to the experience value. The preset condition judging manner in example #4 can be in the development stage of the first device.

[0091] In example #5, the SER of the message transmitted between the first device and the second device is greater than a second threshold in the first time unit, at this time, the preset condition is not met. Based on the service scenarios such as call, voice and video, the SER of the message received by the communication receiver is high, for example, the signal quality is poor, the call is not clear, the call is interrupted, the sound is interrupted, and so on. The preset condition judging manner in example #5 can be in the stage of using the first device by the user.

[0092] In example #6, the receiving module of the first device is in a closed mode (rx off) in the first time unit, at this time, the preset condition is not met, for example, the network device or other terminal device does not transmit the message to the first device in the first time unit, or the first device is in the inter-frequency measurement process in the first time unit.

[0093] In example #7, the first time unit is an uplink transmission resource, at this time, the preset condition is not met, for example, according to the 3GPP TDD frequency band standard, the first time unit is an uplink (uplink) time slot U. That is, when the first time unit is the uplink time slot U, the log record #1 corresponding to the first device as a receiver is not generated.

[0094] Example #8: The RSRP corresponding to the communication link between the first and second devices changes abruptly within the first time unit, at which point the preset conditions are not met. For example, the RSRP experiences a cliff-like change within the first time unit.

[0095] If the preset conditions are met, and log record #1 has been generated, the storage module will store log record #1.

[0096] For example, the processing module is a cellular communication baseband chip. When the preset conditions are met, the cellular communication baseband chip generates log record #1 and writes the generated log record #1 into the log buffer. The AP chip writes the log record #1 in the buffer into the disk / hard disk space of the first device from time to time according to the disk writing rules.

[0097] For example, Figure 4 As shown, when the cellular communication baseband chip is in working mode, it continuously generates cellular communication maintenance logs according to the time-domain resource granularity and cyclically writes the generated maintenance logs to a log buffer, such as random access memory (RAM). The AP chip writes the logs in the buffer to the disk / hard disk space of the first device at irregular intervals according to the disk writing rules. However, the disk / hard disk space is fixed, and if the cellular communication baseband chip generates logs too quickly, the logs stored on the disk / hard disk will be overwritten more quickly. The method 300 provided in this application can reduce the number of cellular communication maintenance logs generated by preset conditions. This reduces the memory space occupied by maintenance logs, such as log record #1, in the first device, avoiding the possibility that the logs in the memory of the first device will be overwritten in a short time, thus avoiding the problem that critical logs required for locating problems in the first device or performing other processing will be overwritten in a short time.

[0098] Figure 5 This is a flowchart illustrating another method for generating logs provided in an embodiment of this application.

[0099] like Figure 5 The method 500 shown can be used in a terminal device, which includes a first processing module, a second processing module, and a storage module. The method 500 includes the following steps:

[0100] S501, the first processing module generates log record #2 based on the first time information from the second processing module. Log record #2 includes the first time information. The first time information is used to determine the absolute time of generating log record #3 by combining with the second time information. Log record #3 is generated by the first processing module and stored in the storage module. Log record #3 includes the second time information.

[0101] For example, the first processing module cannot obtain absolute time, when generating the log record #3 (corresponding to the second log record in the invention), the log record #3 includes time, for example, x hour x minute x second, which can be generated based on the local clock of the first processing module, at this time, the specific date of generating the log record #3 cannot be determined. The second processing module can obtain absolute time and send it to the first processing module, that is, the first time information is absolute time, the first processing module generates the log record #2 (corresponding to the first log record in the invention) based on the absolute time, the log record #2 includes the absolute time, for example, x year x month x day x hour x minute x second, the log record #2 and the log record #3 are sequentially stored in the storage module, and when the problem is located by subsequently capturing the log, the absolute time of generating the log record #3 can be recovered according to the log record #2 and the log record #3.

[0102] The log record #2 and the log record #3 can be understood as log records generated by the first processing module and used for different purposes, the log record #2 is used to determine the absolute time of generating the log record #3, and the log record #3 records specific operations or matters performed by the terminal device in the absolute time, and is used to provide specific content executed by the terminal device in the absolute time when the problem is subsequently located. The absolute time of generating the log record #3 can be understood as the absolute time at which the operation recorded in the log record #3 is actually performed by the terminal device. Optionally, the method 500 further includes:

[0103] The second processing module periodically sends the first time information to the first processing module.

[0104] In a possible implementation, the second processing module sends the first time information to the first processing module according to a preconfigured period.

[0105] For example, the first time information is x year x month x day, the second time information included in the log record #3 is x hour x minute x second, and the preconfigured period can be one day; or the first time information is x year x month, the second time information included in the log record #3 is x day x hour x minute x second, and the preconfigured period can be one month; or the first time information is x year x month x day x hour, the second time information included in the log record #3 is x minute x second, and the preconfigured period can be one hour, and so on.

[0106] Exemplarily, the first processing module is a radio frequency chip for amplifying power of a radio frequency signal, or the first processing module is a chip for controlling whether to radiate the radio frequency signal, and the first processing module controls whether to radiate the radio frequency signal in two cases, one control is that the first processing module feeds the radio frequency signal to an antenna to radiate out, and the other control is that the first processing module shields the radio frequency signal, that is, controls not to feed the radio frequency signal to the antenna, that is, controls not to radiate the radio frequency signal out. For example, the first processing module is a radio frequency enhancement chip. The first processing module cannot know absolute time, and can only perceive running time of itself, for example, the first processing module has a sleep time, and the local clock of the first processing module does not count during the sleep time, or the local clock of the first processing module is out of synchronization for a long time to cause time error.

[0107] Exemplarily, the second processing module is an AP chip, and the AP chip can communicate, that is, can perform time synchronization, and can obtain accurate absolute time, for example, x years, x months, x days, x hours, x minutes and x seconds.

[0108] S502, the storage module stores the log record #2.

[0109] Exemplarily, the radio frequency enhancement chip writes the generated log record #2 into a log buffer, and the AP chip writes the log record #2 in the buffer into a disk / hard disk space of the terminal device at irregular time according to a disk writing rule.

[0110] The storage module can store the log record #2 and the log record #3, and when a problem occurs subsequently and log grabbing and analysis are needed, for example, the log record #3 needs to be grabbed, but the time included in the log record #3 is not the absolute time of generating the log record #3, at this time, the log record #2 also needs to be grabbed to restore the absolute time of generating the log record #3, so as to locate the problem.

[0111] Optionally, the terminal device further includes a third processing module, and the method 500 further includes:

[0112] The third processing module obtains the log record #2 and the log record #3 from the storage module; the third processing module generates a log record #4 based on the log record #2 and the log record #3, and the log record #4 includes the absolute time of generating the log record #3 and all or part of information in the log record #3 except time information.

[0113] If the third processing module needs log record #3 when locating the problem, the third processing module can generate log record #4 (corresponding to the third log record in the invention) based on log record #2 and log record #3 in the storage module, and log record #4 includes the absolute time of generating log record #3 and all or part of the information in log record #3 except the time information. That is, after generating log record #4, the third processing module can directly locate or troubleshoot the problem according to log record #4.

[0114] Optionally, the method 500 further includes:

[0115] The storage module stores log record #4, and the log file where log record #4 is located does not contain log record #2 and log record #3.

[0116] For example, the log file where log record #4 is located is different from the log file where log record #2 and / or log record #3 are located. Log record #2 and log record #3 can be in the same log file or in different log files, which is not limited in the present application.

[0117] It should be noted that generating log record #2 can be before generating log record #3, and generating log record #2 can be after generating log record #3, which is not limited in the present application. Therefore, storing log record #2 can be before storing log record #3, and storing log record #2 can be after storing log record #3, which is not limited in the present application.

[0118] As shown in Figure 6 The radio frequency enhancement chip continuously generates log record #3 when in the working mode, and periodically generates log record #2. The generated logs are cyclically written into the log buffer, such as RAM. The AP chip writes the logs in the buffer into the disk / hard disk space of the terminal device at irregular time according to the disk writing rule.

[0119] The method 500 provided in the application records the second time information in the generation of a certain log record #3, for example, the second time information can be the time information generated by the local clock, records the first time information for determining the absolute time of generating the log record #3 in the log record #2, for example, the first time information can include the information for determining the year / month / day of generating the second log record, and since the first time information can determine the absolute time of generating a plurality of log records #3 corresponding to the same first time information in combination with a plurality of second time information. Therefore, the method 500 provided in the application can store a plurality of log records #3 recording the second time information and the log record #2 when storing the log subsequently. Relative to storing a plurality of log records #3, each log record #3 records the absolute time of generating the log record #3, the scheme provided in the application can save more memory resources in the process of storing the log, and thus can avoid the problem that the log is covered in the memory of the terminal device for a short time, thereby avoiding the problem that the key log required for positioning the terminal device problem or other processing is covered in a short time.
