Detailed ways

For ease of understanding, terms involved in this application are first introduced.

1. Double data rate synchronous dynamic random access memory (double data rate SDRAM, DDR)

DDR is a double-rate synchronous dynamic random access memory (SDRAM), that is, the data transfer rate of DDR is twice as high as that of SDRAM. This doubling rate is not simply doubling the clock cycle, but DDR can transfer data twice in the clock cycle that SDRAM transfers data once. Therefore, DDR has the characteristics of fast access and easy to read and write.

2. Non-volatile memory (Flash EEPROM Memory, Flash)

Flash can also be called "flash memory" or "flash memory", which is essentially an electrically erasable programmable read-only memory (EEPROM), which combines random access memory (Random access memory, The advantages of RAM) and read only memory (ROM) are not only large capacity, but also high access speed, easy to erase and rewrite, and low power consumption. Flash is often used in the internal storage space of terminal equipment because it can maintain stored information for a long time without powering on.

Please refer to FIG. 1. FIG. 1 is a flowchart of a method for saving logs according to an embodiment of the present application. The log saving method can be implemented by a terminal device or by a chip in the terminal device.

The terminal device is an entity on the user side for receiving or transmitting signals, such as a mobile phone. A terminal device may also be called a terminal (terminal), a user equipment (UE), a mobile station (mobile station, MS), a mobile terminal (mobile terminal, MT), and the like. The terminal device can be a mobile phone (mobile phone), a wearable device, a tablet computer (Pad), a computer with a wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, industrial Wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical surgery, wireless terminals in smart grid, transportation security safety), wireless terminals in smart cities, wireless terminals in smart homes, to support enhanced Machine-Type communication (eMTC) and/or to support general purpose Terminal equipment of long term evolution (LTE) of mobile communication technology, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal device.

As shown in FIG. 1 , the log saving method includes but is not limited to the following S101 to S103 , and the method shown in FIG. 1 is described by taking the application to the above-mentioned terminal device as an example.

S101, the terminal device detects whether the system is abnormal.

It should be noted that the terminal device can always detect whether there is an abnormality in the system; if there is an abnormality, the terminal device can take timely measures (for example, restart the system) to avoid more serious problems such as system crash, which affects the user experience.

In an implementation manner, the terminal device can detect whether there is an abnormality in the system by means of hardware or software. For example: configure a timer circuit in the terminal device, you can regularly check the internal situation of the chip in the system, and send a signal once an error occurs, such as a restart signal.

S102, in the case that the terminal device detects an abnormality, save the log information corresponding to the abnormality in the DDR.

The log information corresponding to the above abnormality can be understood as log information of the corresponding system during the period from the moment when the terminal device detects the abnormality to the time when the terminal device takes measures to recover the abnormality. In the embodiment of the present application, the log information corresponding to the exception is stored separately. On the one hand, the log information corresponding to the exception is less than all the log information, which can save the storage time; on the other hand, it is stored in a targeted manner. , the log information corresponding to the exception can be stored centrally, which is convenient for subsequent analysis of the abnormal situation and the abnormal solution.

In an implementation manner, saving the log information corresponding to the above exception in the DDR includes: the terminal device saves the above log information in a preset storage space in the DDR, where the preset storage space is reserved by the DDR for storage Storage space for exception log information.

It should be noted that the preset storage space is a dedicated storage space in the DDR and cannot be occupied by other information. In other words, the storage space can only be used to store log information corresponding to the abnormal state, but cannot be used to store other types of information.

When a system abnormality is detected, in order not to affect the user experience, the sooner measures are taken to repair the abnormality, the better to avoid more serious situations. Therefore, it is necessary to control the time for saving the log information corresponding to the abnormality to be shorter. the better. It can be seen from the foregoing that the DDR has the characteristics of fast access and easy read and write. Therefore, if a dedicated storage space is reserved in the DDR for use when an abnormality is detected, the corresponding log information can be stored more quickly.

S103, the terminal device restarts the above system.

In an implementation manner, the above-mentioned terminal equipment detecting whether the system is abnormal includes: the above-mentioned terminal equipment detecting whether the subsystem is abnormal; and the above-mentioned terminal equipment restarting the system includes: the terminal equipment restarting the above-mentioned subsystem.

It should be noted that, if the terminal device detects that the subsystem is abnormal, the terminal device may choose to repair the abnormality by restarting the subsystem. In this way, the above exceptions can be fixed without affecting the user experience as much as possible. Optionally, when the terminal device detects that the subsystem is abnormal, it can also choose to restart the system to repair the abnormality. For example, after the terminal device restarts the subsystem, if the above exception is not repaired, you can choose to restart the system.

In an implementation manner, after the above-mentioned terminal device restarts the above-mentioned system, the method further includes: the terminal device uploads the log information stored in the above-mentioned DDR to the server.

It should be noted that, after the above exception is repaired, the log information corresponding to the above exception is uploaded to the server, so that the abnormality can be reported as soon as possible, so that the cause of the abnormality can be determined as soon as possible. On the other hand, since DDR cannot store information for a long time, uploading directly from DDR to the server can more effectively ensure the upload of log information and avoid the loss of logs in the middle.

In an implementation manner, uploading the log information stored in the DDR by the terminal device to the server includes: uploading the log information stored in the DDR to the server when the terminal device is connected to a wireless network.

Wherein, connecting to a wireless network can be understood as when the terminal device is in a Wi-Fi state. It should be noted that, when the terminal device is connected to the wireless network, the information in the DDR is uploaded to the server, which can save the user's traffic while ensuring the upload rate. Optionally, the terminal device can upload the information in the DDR to the server at any other time; for example, when the user's own traffic is sufficient, the user can choose the upload time by himself.

In an implementation manner, after the terminal device restarts the system, the method further includes: the terminal device saves the log information in the Flash.

Among them, Flash is the internal storage space of the terminal device. As can be seen from the foregoing content, although the time for writing to the DDR is much shorter than the time for writing the Flash, the Flash has a larger capacity and can store more information. Therefore, after the terminal device takes restarting measures to repair the abnormality, the log information corresponding to the above abnormality can be saved in the Flash.

It should be noted that, as can be seen from the foregoing, log information cannot be stored in DDR for a long time. For example, if an abnormality is detected in the system after the terminal device is restarted, the log information corresponding to the last abnormality in the DDR may be displayed. It is overwritten by the log information corresponding to the new exception; therefore, in order to ensure that the log information of the exception can be completely preserved, the log information stored in the DDR can be saved to the Flash as soon as possible.

In an implementation manner, the terminal device saves the above log information in the Flash, which includes: when the terminal device is in an idle state, save the above log information in the Flash.

The idle state can be understood as a state in which the terminal device is not running any background programs. When the terminal device is in an idle state, the log information saved in the DDR is saved in the Flash, which can effectively avoid occupying the background running space, thereby ensuring the user experience.

It should be noted that, since the DDR itself cannot store the log information persistently, the log information in the DDR can be transferred to the Flash as soon as possible. After the Flash receives the above log information, it can delete the log information in the DDR for use when an exception occurs next time.

In an implementation manner, the above method further includes: uploading the log information saved in the above Flash to the server by the terminal device.

It should be noted that, in addition to storing log information corresponding to exceptions in the DDR, the above-mentioned Flash can also be used to store daily log information of the system and information other than log information. Although the capacity of Flash is larger than that of DDR, if too much information is stored, its performance will still be affected to a certain extent. Therefore, Flash can upload the stored information to the server within a certain period, so that it can be easily searched or used when needed later. The period for uploading log information may be set to T1, and the period for uploading other information may be set to T2. The above-mentioned T1 and T2 are both adjustable parameters, which are not limited in this application.

In an implementation manner, uploading the log information stored in the Flash to the server by the terminal device includes: uploading the log information stored in the Flash to the server when the terminal device is connected to a wireless network.

As can be seen from the foregoing, when the terminal device is connected to the wireless network, the information in the Flash is uploaded to the server, which can save the user's traffic while ensuring the upload rate. Optionally, the terminal device can also upload the information in the Flash to the server at any other time; for example, when the user's own traffic is sufficient, the user can choose the upload time by himself.

It should be noted that, after the information in the Flash is backed up in the server, in order to ensure that the Flash can continue to store new information, the previously stored information may be deleted. Specifically, you can set timed deletion according to time, for example, set to delete information older than 6 months; or you can set quantitative deletion according to memory capacity, for example: when the information storage capacity reaches 50%, set to delete all information. The above contents are only used for examples and do not limit the application.

Through the above log saving method, the log information corresponding to the exception can be quickly saved, and the log information can be effectively ensured to be uploaded to the server, so that the exception can be reported as soon as possible.

Please refer to FIG. 2 , which is a flowchart of another log saving method provided by an embodiment of the present application. The log saving method can be implemented by a terminal device or by a chip in the terminal device. As shown in FIG. 2 , the log saving method includes, but is not limited to, the following S201 to S206 , and the method shown in FIG. 2 is described by taking the application to the above-mentioned terminal device as an example.

S201, the terminal device reserves a dedicated storage space in the DDR;

S202, the terminal device detects whether the system is abnormal;

Optionally, whether the above-mentioned terminal device detection system is abnormal includes: whether the terminal device detects whether the subsystem is abnormal.

S204, the terminal device restarts the system;

Optionally, restarting the system by the terminal device includes: restarting the subsystem by the terminal device.

S205, the terminal device uploads the log information stored in the DDR to the server;

S206, the terminal device saves the log information stored in the DDR to the Flash;

It should be noted that the above steps of S205 and S206 are in no particular order, and S205 may be implemented first, or S206 may be implemented first.

Optionally, after implementing S205, the terminal device may save the log information stored in the DDR to the Flash. The user can set the subsequent operations of this mode according to requirements, which is not limited in this application. After S205 in FIG. 2 , other steps that can be taken are not shown, which does not limit the embodiment of the present application.

S207, the terminal device uploads the log information stored in the Flash to the server.
