Optionally, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect the user's touch operation on or near it (such as the user's operation on the touch panel 1071 or near the touch panel 1071 using any suitable object or accessory such as a finger, stylus, etc.), and drive the corresponding connection device according to a pre-set program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into the touch point coordinates, and then sends it to the processor 110, and can receive and execute the command sent by the processor 110. In addition, the touch panel 1071 can be implemented in various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may also include other input devices 1072.

[0040] Optionally, the touch panel 1071 may cover the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. Then, the processor 110 provides corresponding visual output on the display panel 1061 according to the type of touch event. Figure 1 In the figure, the touch panel 1071 and the display panel 1061 are used as two independent components to realize the input and output functions of the smart terminal. However, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to realize the input and output functions of the smart terminal, which is not limited here.

[0042] The memory 109 can be used to store software programs and various data. The memory 109 can mainly include a program storage area and a data storage area. Optionally, the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the mobile phone (such as audio data, a phone book, etc.), etc. In addition, the memory 109 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0043] The processor 110 is the control center of the smart terminal. It uses various interfaces and lines to connect various parts of the entire smart terminal. It executes various functions of the smart terminal and processes data by running or executing software programs and / or modules stored in the memory 109, and calling data stored in the memory 109, so as to monitor the smart terminal as a whole. The processor 110 may include one or more processing units; preferably, the processor 110 may integrate an application processor and a modem processor. Optionally, the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 110.

[0044] The intelligent terminal 100 may further include a power supply 111 (such as a battery) for supplying power to various components. Preferably, the power supply 111 may be logically connected to the processor 110 via a power management system, thereby implementing functions such as charging, discharging, and power consumption management through the power management system.

[0045] although Figure 1 Not shown, the smart terminal 100 may also include a Bluetooth module, etc., which will not be described in detail here.

[0046] To facilitate understanding of the embodiments of the present application, the communication network system on which the smart terminal of the present application is based is described below.

[0047] See also Figure 2 , Figure 2 A communication network system architecture diagram is provided for an embodiment of the present application. The communication network system is an LTE system of universal mobile communication technology. The LTE system includes a user equipment (UE) 201, an evolved UMTS terrestrial radio access network (Evolved UMTS Terrestrial Radio Access Network, E-UTRAN) 202, an evolved packet core network (Evolved Packet Core, EPC) 203 and an operator's IP service 204 that are connected in communication in sequence.

[0048] Optionally, the user equipment 201 may be the above-mentioned terminal 100, which will not be described in detail here.

[0049] The evolved UMTS terrestrial radio access network 202 includes an eNodeB 2021 and other eNodeBs 2022. Optionally, the eNodeB 2021 may be connected to other eNodeBs 2022 via a backhaul (e.g., an X2 interface), and the eNodeB 2021 is connected to the evolved packet core network 203, and the eNodeB 2021 may provide access from the user equipment 201 to the evolved packet core network 203.

[0051] The IP service 204 may include the Internet, an intranet, an IMS (IP Multimedia Subsystem) or other IP services.

[0052] Although the above introduction takes the LTE system as an example, those skilled in the art should know that the present application is not only applicable to the LTE system, but also to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, 5G and future new network systems (such as 6G), etc., without limitation here.

[0053] Based on the above-mentioned smart terminal hardware structure and communication network system, various embodiments of the present application are proposed.

[0054] First embodiment See also Figure 3 , is a data management method provided in an embodiment of the present application. The method can be executed by a data management device provided in an embodiment of the present application. The data management device can be implemented in software and / or hardware. Optionally, the data management device can be a smart terminal or a host in a smart terminal, etc.

[0055] Optionally, the intelligent terminal may be the mobile terminal in the above embodiment, and the data management method comprises the following steps: S10: In response to triggering a data reading operation, acquiring target data; Optionally, the intelligent terminal establishes a communication connection with at least one storage area through a device or component for data processing (such as a processor), so as to trigger a data reading operation in real time or at a preset time interval, and obtains target data from at least one storage area. The target data can be any data stored in any storage area. When the data reading operation is triggered, the target data and its logical address are determined.

[0056] S20: In response to a preset condition being met, performing a preset erasing operation on the storage area of ​​the target data.

[0057] Optionally, after the smart terminal or the host in the smart terminal triggers a data reading operation, the target data is acquired, and the target data is detected to detect whether the target data meets a preset condition. When the preset condition is met, the storage area of ​​the target data is erased.

[0058] Optionally, the target data in the storage area is erased.

[0059] Optionally, the preset conditions are met, including at least one of the following: Belongs to the exchange area data; There is no universal data format; The storage requirements of multiple preset storage areas cannot be met simultaneously.

[0060] Optionally, the preset erasing operation includes one of the following: TRIM erasure; Discard.

[0061] Optionally, the TRIM erase operation uses a TRIM function, and after the host in the smart terminal identifies data that is no longer needed, it outputs a TRIM command so that the storage area erases data according to the TRIM command. Depending on different types of storage technologies, the write block content of the TRIM function is configured as '0' or '1'.

[0062] Optionally, the Discard erasure uses a Discard function, and the host in the smart terminal uses a longer time to identify data that is no longer needed, and then outputs a Discard command so that the storage area erases the data according to the Discard command. The host in the smart terminal can partially or completely access the original data, so that the data portion that the host in the smart terminal can no longer access is deleted or unmapped, and the Discard function performs an erasure operation by discarding the data.

[0063] Optionally, acquiring the target data further includes: acquiring a preset identifier of the target data and / or a logical address of the storage area to which it belongs.

[0064] Optionally, a preset identifier and / or a logical address is used to detect whether the target data meets a preset condition. If the target data meets the preset condition, it is determined that the target data is no longer needed and needs to be cleared, and the storage area is reclaimed.

[0065] Optionally, the preset flag can be set according to actual needs, such as "0" or "1", and the preset flag can be set in the data reading operation. During the data reading operation, the host in the intelligent terminal sends a read instruction to the storage area, so that the preset flag is included in the read instruction. For example, assuming that the size of the read instruction is 2 bytes, that is, 16 bits, the 16th bit can be used as an identification bit. If the identification bit is "1", it means that the read instruction includes a preset identification. If the identification bit is not "1", it means that the data read request does not include a preset identification.

[0066] Optionally, the storage area of ​​the target data may be a virtual memory or the like.

[0067] In this way, it is possible to quickly and accurately determine whether the target data is exchange area data, does not have a common data format or cannot simultaneously meet the storage requirements of multiple preset storage areas, further improving the smoothness of the operation of the smart terminal.

[0068] Optionally, the method further includes (preferably, before step S10): writing the target data and its preset identifier into the storage area.

[0069] The smart terminal or the host in the smart terminal writes the target data into the storage area. Based on the write operation, the preset identifier of the target data is written into the storage area. By writing the target data into the storage area in advance, the target data can be obtained from the storage area during subsequent data reading operations, and the operation is convenient.

[0070] Optionally, the preset erasing operation includes: marking the state of the target data as invalid; determining the storage area of ​​the target data according to the logical address and / or the preset identifier, and erasing the storage area.

[0071] Optionally, after the target data meets the preset conditions, the target data is marked as invalid. When the invalid space is reclaimed by the garbage collection process, the target data is not moved, thereby reducing write amplification. At the same time, due to the reduction in the amount of valid data moved, the frequency of garbage collection is also reduced, thereby improving the smoothness of the operation of the smart terminal.

[0072] Optionally, the preset erasing operation further includes: deleting a mapping relationship corresponding to the target data in the data mapping table.

[0073] Optionally, the content stored in the data mapping table is the mapping relationship between the logical address and the physical address. The data mapping table is queried using the logical address (relative address used in the user program) to find the corresponding physical address (absolute address of the actual storage unit), and then the actual storage unit is read and written to obtain the corresponding data. After deleting the mapping relationship corresponding to the target data in the data mapping table, the mapping from the logical address of the target data to the corresponding physical address will be disconnected, so that the target data can no longer be read, thereby ensuring that the target data cannot be moved when the invalid space is recovered during the garbage collection process. Optionally, deleting the mapping relationship corresponding to the data can be understood as disconnecting the mapping from the logical address of the data to the physical address. For example, the physical address of the data recorded in the data mapping table can be replaced with an undefined symbol.

[0074] For example, assuming that the target data "DATA.doc" is written in the logical address A, if the specified target data is written to the virtual memory a, and the address B of the target data in the virtual memory a is written at the Ath position in the data mapping table, that is, the physical address of the target data, and after the data read operation is triggered, "DATA.doc" is obtained. Since the virtual memory a belongs to the swap area, after reading the target data "DATA.doc", the data in the Ath position in the data mapping table can be changed to invalid data, such as undefined symbols, etc., thereby deleting the mapping relationship corresponding to the target data "DATA.doc" in the data mapping table.

[0075] Optionally, the method further includes (preferably, before step S10): enabling a data management function so as to detect whether the target data meets a preset condition when a data reading operation is triggered.

[0076] Optionally, the user sets whether to enable the data management function on the smart terminal. After the user determines to enable the data management function, the smart terminal or the host in the smart terminal detects whether the acquired target data meets preset conditions when triggering a data reading operation.

[0077] Optionally, the data management function can be regarded as marking the target data as invalid after reading the target data when the target data to be read meets the preset conditions, and then deleting the mapping relationship corresponding to the target data in the data mapping table based on the invalid target data to erase the corresponding storage area, thereby further improving the smoothness of the operation of the smart terminal and / or extending its service life.

[0078] In summary, in the data management method provided in the embodiments of the present application, the smart terminal or the host in the smart terminal, during a data reading operation, determines that the target data meets the preset conditions, and then performs a preset erasing operation on the storage area of ​​the target data without considering the data format requirements or storage requirements of the storage area, thereby improving the versatility of data management, and / or improving the smoothness of the operation of the smart terminal and / or extending its service life.

[0079] Second embodiment Based on the same inventive concept as the above embodiment, a specific example is used to explain in detail. In this example, the intelligent terminal or the host in the intelligent terminal is HOST, the storage area is Device, the target data is A, the exchange area data is ROD area data, and marking the state of the target data as invalid is marking the state of the target data as an invalid block as an example.

[0080] In the existing data management method, after the HOST writes data A and B into the ROD area in the Device by sending a data write request to the Device for writing data A and B into the ROD area, if a data read request is sent to the Device for reading data A, since the Device reads data A from the ROD area in response to the data read request, data A is still valid data, so the Device needs to move data A and B during subsequent garbage collection (GC, Garbage Collector), and there are invalid data blocks when rewriting data A, which not only causes a waste of resources, but also affects the smoothness of terminal operation.

[0081] The data management method provided by the embodiment of the present application, during the data management process, when the HOST triggers a data write operation, data A and B are written to the ROD area specified in the Device, and when the HOST triggers a data read operation, data A is read from the ROD area, and it is detected that data A belongs to the ROD area, and data A is marked as an invalid block, that is, the physical address of data A recorded in the data mapping table is replaced with an undefined symbol to disconnect the mapping of the logical address of data A to the physical address, and the data A stored in the ROD area is erased, so that only data B needs to be moved during subsequent garbage collection, and data B does not need to be moved, thereby reducing the amount of valid data moved and the frequency of garbage collection, and there are no invalid data blocks when rewriting data A, which can save storage space.
