Description

Terminal and data processing method

technical field

The present invention relates to the technical field of communications, and in particular, to a terminal and a data processing method.

Background technique

The traditional dual-standby architecture is shown in Figure 1. All data of external devices is processed by one CPU, and two Modems (Modem1 and Modem2) can exchange data such as voice services and data services with one CPU, and all data are stored in the One phone memory (RAM) and one phone memory (EMMC).

Due to the traditional dual standby architecture, one CPU handles the data of all external devices, which will slow down the data processing speed. All data, including voice service data, data service data and other data, are processed by the CPU. Therefore, the data is easily confused, and the security and privacy of important data such as address books, SMS, security passwords, and bank accounts cannot be effectively guaranteed. , Seriously affecting the user's data security. And all the data are only saved by one RAM and EMMC, the increase of the amount of data will affect the stability of RAM and EMMC and cause the terminal to crash.

At present, there is no corresponding technology to solve the problems faced by related technologies.

Contents of the invention

Based on at least one of the above technical problems, the present invention proposes a new technical solution, which can filter private data and non-private data in external devices interacting with the terminal and process them respectively by different processors, avoiding It eliminates data confusion, ensures the security of private data in the terminal, and improves user experience.

In view of this, the present invention proposes a terminal, including: a monitoring unit, configured to receive data from an external device of the terminal, and judge the data, and when it is judged that the data is private data, the The private data is sent to the first processing unit, and when the data is determined to be non-private data, the non-private data is sent to the second processing unit; the first processing unit, for the private data After processing, the interaction data in the private data is sent to the first communication unit and/or the second communication unit; after the second processing unit processes the non-private data, the non-private data is The interaction data in the transmission is sent to the first communication unit and/or the second communication unit; the first communication unit is connected to the first processing unit and the second processing unit, and the private data The interaction data in the non-private data and/or the interaction data in the non-private data are sent to the outside; the second communication unit is connected to the first processing unit and the second processing unit, and the interaction data in the private data The interaction data and/or the interaction data in the non-private data are sent to the outside.

In order to improve data security, the terminal is equipped with multiple processors, and some of the processors are designated to process the user's private data, and the rest of the processors are used to process the user's non-private data, so that many data can be divided into multiple categories. Processing can not only speed up the response speed, but also ensure data security and improve system stability.

Since both the first processing unit and the second processing unit can be connected to the external device, and the data from the external device includes private data and non-private data, in order to ensure that the private data and non-private data from the external device are processed separately Therefore, a monitoring unit is set between the external device and the processing unit to judge the data type, that is, it is divided into private data and non-private data to ensure the accuracy of data classification, and different types of data are sent to the Different processing units ensure the security of data processing.

Both the first communication unit and the second communication unit can send the interaction data processed in the first processing unit and the second processing unit to the outside, that is, the first communication unit and the second communication unit can both process the private data and Non-private data is forwarded. Specifically, the communication unit that sends the interactive data can be selected according to the working state of the communication unit, for example, the communication unit in the idle state can be preferentially selected to send the real-time interactive data, so as to shorten the waiting time for data transmission and optimize the performance of the system.

Private data refers to data that belongs to personal privacy for users, such as passwords, account numbers, SMS content, email content, financial data, etc., while non-private data refers to data that does not belong to personal privacy for users. Examples include downloaded music, e-books, radio data, web news, etc.

External devices refer to other related devices of the terminal other than processors and communication units, such as screens, sensors, Bluetooth, WIFI, cameras, etc.

It should be understood that in addition to classifying data according to user privacy, other classification methods may also be used, for example, data related to contacts is processed by the first processing unit, and other data is processed by the second processing unit.

In the above technical solution, preferably, further comprising: a first storage unit, connected to the first processing unit, for storing the private data processed by the first processing unit; a second storage unit, connected to The second processing unit stores the non-private data processed by the second processing unit.

In this technical scheme, private data and non-private data are stored through different storage units, which avoids the confusion of storage between private data and non-private data and ensures the security of private data. The first storage unit and the second A storage unit may be a memory and/or a memory. On the other hand, since private data and non-private data are stored in different spaces and processed by different processors, the data processing speed is improved.

In the above technical solution, preferably, it further includes: an update unit, which updates the judgment conditions for filtering the data according to the received update instruction, so that the monitoring unit performs private data and non-private data according to the updated judgment conditions. Judgment on private data.

In this technical solution, with the increase of terminal services, the types of user's private data will also change. For example, in communication services, SMS, address book, etc. belong to the user's private data; in the terminal system, the switch password, Application protection passwords, terminal anti-theft passwords, and screen unlock passwords also belong to the user's private data. By updating the judgment conditions for data screening, the data screening is made more accurate, thereby ensuring the security of the user's private data.

In the above technical solution, preferably, the determination condition includes classifying all applications on the terminal into protected applications and unprotected applications, the private data belongs to the data under the protected applications, and the non-protected applications Private data belongs to the data under the unprotected application.

In this technical solution, the user or manufacturer can set the conditions for determining the type of data. Specifically, all applications in the terminal can be divided into protected applications and unprotected applications, so that when the monitoring unit receives data, The attribute of the data is judged by judging the type of the application to which the data belongs. If the data belongs to a protected application, the data is private data, otherwise, it is non-private data. For example, a chat tool can be regarded as a protected application, and a music player can be regarded as an unprotected application, and then it can be determined that the data generated by the chat tool belongs to private data, while the data generated by the music player belongs to non-private data. Certainly, the user or the manufacturer may also set other determination conditions as required, such as the data related to the contact is private data, other data is non-private data, and so on.

In the above technical solution, preferably, the monitoring unit is further configured to send an interrupt signal to the second processing unit when the first processing unit needs to interact with the external device according to the private data, and interrupt The non-private data interaction between the second processing unit and the external device, and when the first processing unit finishes processing the private data, send a feedback signal to the second processing unit to notify The second processing unit continues to interact with the external device with non-private data; the monitoring unit is also configured to interact with the external device according to the non-private data when the second processing unit needs to interact with the external device , sending an interrupt signal to the first processing unit, interrupting the private data interaction between the first processing unit and the external device, and when the second processing unit finishes processing the non-private data , sending a feedback signal to the first processing unit, notifying the first processing unit to continue the private data interaction with the external device.

In order to coordinate the interaction process and sequence between multiple processors and external devices, this technical solution provides When the first data processing unit needs to urgently process real-time business data, the monitoring unit sends an interrupt signal to the second processing unit for processing non-private data to interrupt the business data being processed by the second processing unit and wait state, when the first processing unit completes the interaction with the external device, the monitoring unit notifies the second processing unit to continue the unfinished data interaction. Through such a processing mechanism, it can ensure that the user's relatively important and urgent business data is prioritized. And it will not affect the processing of other business data. Specifically, a flag can be set in the monitoring unit. When the flag is at a low level, the first processing unit works, and when the flag is at a high level, the second processing unit works. For example, when the user is listening to music ( It belongs to non-private data, which uses the external device speaker and is processed by the second processing unit), and the mobile phone calls suddenly (it belongs to private data, which should be processed by the first processing unit and also needs to use the external device speaker), then the monitoring unit will The flag position is low level, and the incoming call data is handed over to the first processing unit for processing. After the first processing unit has processed the incoming call, the monitoring unit will set the flag position to high level, and the second processing unit will continue to control the external device speaker to play music.

Similarly, when the second processing unit needs to interact with external devices, it also needs to send an interrupt signal to the first processing unit to ensure that the most urgent and recent business data can be processed first.

For example, a chat tool can be regarded as a protected application, and a music player can be regarded as an unprotected application, and then it can be determined that the data generated by the chat tool belongs to private data, while the data generated by the music player belongs to non-private data. Certainly, the user or the manufacturer may also set other determination conditions as required, such as the data related to the contact is private data, other data is non-private data, and so on.

In the above technical solution, preferably, further comprising: when the first processing unit needs to interact with the external device according to the private data, the monitoring unit sends an interrupt signal to the second processing unit, interrupting The non-private data interaction between the second processing unit and the external device, and when the first processing unit finishes processing the private data, the monitoring unit sends Feedback signal to notify the second processing unit to continue the non-private data interaction with the external device; when the second processing unit needs to interact with the external device according to the non-private data, the The monitoring unit sends an interrupt signal to the first processing unit, interrupting the non-private data interaction between the first processing unit and the external device, and completing the processing of the private data at the second processing unit , sending a feedback signal to the first processing unit to notify the first processing unit to continue the private data interaction with the external device.

Since the terminal is equipped with multiple processors, the interaction between the processors and external devices becomes relatively complicated. In order to coordinate the interaction process and sequence between multiple processors and external devices, this technical solution provides When the first data processing unit needs to urgently process real-time business data, the monitoring unit sends an interrupt signal to the second processing unit for processing non-private data to interrupt the business data being processed by the second processing unit and wait state, when the first processing unit completes the interaction with the external device, the monitoring unit notifies the second processing unit to continue the unfinished data interaction. Through such a processing mechanism, it can ensure that the user's relatively important and urgent business data is prioritized. And it will not affect the processing of other business data. Specifically, a flag can be set in the monitoring unit. When the flag is at a low level, the first processing unit works, and when the flag is at a high level, the second processing unit works. For example, when the user is listening to music ( It belongs to non-private data, which uses the external device speaker and is processed by the second processing unit), and the mobile phone calls suddenly (it belongs to private data, which should be processed by the first processing unit and also needs to use the external device speaker), then the monitoring unit will The flag position is low level, and the incoming call data is handed over to the first processing unit for processing. After the first processing unit has processed the incoming call, the monitoring unit will set the flag position to high level, and the second processing unit will continue to control the external device speaker to play music.

Similarly, when the second processing unit needs to interact with external devices, it also needs to send an interrupt signal to the first processing unit to ensure that the most urgent and recent business data can be processed first.

Fig. 4 shows a schematic diagram of a terminal according to an embodiment of the present invention.

As shown in Figure 4, the present invention has increased a CPU, RAM and EMMC on the basis of related technology, processes different data by different CPU like this, and different RAM and EMMC store different data.

For example, it is defined that CPU1 only processes personal private information data (data of protected applications), and the data of protected applications is screened out by setting the monitoring unit (wherein, protected applications include contacts, information, password protection, etc.), and processed by dedicated CPU1 , and stored in the dedicated memory RAM1 and EMMC1, so as to ensure the security of the user's personal private information data; define CPU2 to only process public information data facing the society (data of unprotected applications), and filter out unprotected applications by setting the monitoring unit The data (wherein, unprotected applications include browser, display, camera, simple music and video broadcast, radio, etc.) are processed by dedicated CPU2 and stored in dedicated memory RAM2 and EMMC2. In this way, the data of the protected application and the data of the unprotected application are processed and stored separately, avoiding the mixing of data of different security levels, which can ensure the security of the user's private data, and can greatly improve the processing time of different data. Improve user experience.

The memory corresponding to each processing unit may not only be EMMC, but also may be a storage medium such as nand flash.

Fig. 5 shows a flowchart of a processing method of a first processing unit according to an embodiment of the present invention.

As shown in Figure 5, the flow of the processing method of the first processing unit is as follows:

Step 502, the first processing unit CPU1 processes the private information from the external device screened out by the monitoring unit. It is defined that the first processing unit only processes personal private information data, and applications such as contacts, information, and password protection are set as protected applications, and the first processing unit only processes data of protected applications.

Step 504, storing the private information in the first storage unit (RAM1 and EMMC1), wherein the first storage unit includes a memory and a memory. All data of the protected application is stored in the first storage unit.

Step 506, hand over the private information to the protected application for processing. Thereby ensuring the data security of storing and processing personal private information.

Of course, a second processing unit may also be defined to process private information.

Fig. 6 shows a flowchart of a processing method of the second processing unit according to an embodiment of the present invention.

As shown in Figure 6, the flow of the processing method of the second processing unit CPU2 is as follows:

Step 602, the second processing unit processes the non-private information from the external device filtered by the monitoring unit. It is defined that the second processing unit only processes non-private information data (that is, public information data facing the society), and applications such as taking photos, displaying, and browsing web pages are set as unprotected applications, and the second processing unit only processes data of unprotected applications.

Step 604, storing the non-private information on the second storage unit (RAM2 and EMMC2), wherein the second storage unit includes a memory and a memory. Data of unprotected applications are all stored in the second storage unit.

Step 606, hand over the non-private information to the non-protected application for processing. Thereby ensuring the data security of storing and processing personal private information.

Fig. 7 shows a flowchart of a processing method of a monitoring unit according to an embodiment of the present invention.

As shown in FIG. 7, the process of the processing method of the monitoring unit according to the embodiment of the present invention is as follows:

Step 702, the monitoring unit screens the data from the external device. When the external device interacts with the user, not only the user's private information data, such as wireless network password and other data, but also public data, such as playing music and other data, will be generated. Therefore, a monitoring unit is set between the external device and the terminal processing unit, and the monitoring unit screens out protected data and unprotected data from one or more external devices.

Step 704, the monitoring unit judges whether the data from the external device is private data or non-private data.

Step 706, when the monitoring unit determines that the data from the external device is private data, the private data is handed over to CPU1, RAM1 and EMMC1 for processing and storage, and these data interact with the external device through CPU1.

Step 708, when the monitoring unit determines that the data from the external device is non-private data, hand over the non-private data to CPU2, RAM2 and EMMC2 for processing and storage.

Therefore, in this embodiment, data screening rules are preset in the monitoring unit, and all application data are classified into core applications and non-core applications. Core applications are protected applications, and non-core applications are protected applications. Protected applications, core applications can be applications that contain user privacy data, such as voice service data (address book, call records, information), email in data service data, account information saved, recording in multimedia applications, downloading through payment Audio and video, power on and off passwords in the system, mobile phone anti-theft passwords, screen unlock passwords, data information encryption in file managers, backup applications, notepads, non-core applications are applications that do not involve user privacy data, such as data business data browsers, webcams, simple display applications, radios. The monitoring unit judges the data in the external device according to the preset filtering rules, and judges whether the data is private data, and if the data is private data, sends the private data to a processor dedicated to processing private data for processing.

Since the screening rules are the basis for distinguishing private data from non-private data, and the accuracy of the basis will affect the accuracy of data distinction, in order to ensure that the basis can be updated according to the development of applications and businesses, when new applications are found, or new services, whether to update the screening rules can be determined according to whether the new applications and new services involve personal privacy, that is, new applications and new services that involve private data will be classified into data categories that involve private data, and those that do not involve private data New applications and new services are classified into data categories involving non-private data. For example, after the terminal newly downloads a psychological FM application, it is determined that the application does not involve private data, then the application can be classified into non-core application categories, and the division can be manually selected by the user, or it can be based on other terminal Judging the application to automatically determine whether the application is an application that does not involve private data.

In addition, the monitoring unit is also used to send an interrupt signal to the CPU2 used to process non-private data, to interrupt the CPU2 processing The business data is in a waiting state. When CPU1 completes the interaction with external devices, the monitoring unit notifies CPU2 to continue the unfinished data interaction. Through such a processing mechanism, it can ensure that the relatively important and urgent business data of the user is processed first. And it will not affect the processing of other business data. Specifically, a flag bit can be set in the monitoring unit. When the flag bit is low level, CPU1 works, and when the flag bit is high level, CPU2 works.

The technical solution according to the present invention will be further described below with reference to FIG. 8A and FIG. 8B .

As shown in Figure 8A, in step 802, it is judged whether the current service requires CPU1 to interact with the external equipment of the terminal. Suppose the current user terminal receives an incoming call, which belongs to the user's private data, so it is handed over to CPU1 for processing, and it is determined that CPU1 is processing the call. Incoming data needs to interact with audio processing equipment such as speakers. If the current service does not require the CPU1 to interact with the external device of the terminal, the process ends.

Step 804, judge whether CPU1 is currently connected to the audio processing device, if not connected to the audio processing device (indicating that the audio processing device is currently connected to CPU2), go to step 806, otherwise, end the process.

Step 806, CPU1 sends an interrupt signal to CPU2, so that CPU2 disconnects from the audio processing device.

Step 808, CPU1 connects with the audio processing device.

Therefore, when CPU2 is processing the non-private data of the player application data and is connected with the audio processing device, if an incoming call is received at this time, the connection between CPU2 and the audio processing device can be interrupted, so that CPU1 can be connected with the audio processing device, Even if the audio processing device is occupied by CPU2, it can receive incoming calls in time.

After the service processing of CPU1 is finished, CPU2 may be notified to continue the unfinished business, for example, to continue playing music. With such a processing mechanism, the business can be carried out in an orderly manner under the coexistence of multiple processors, without affecting the normal use of users, and since multiple processors are used to process different data, it not only improves data processing Speed, but also further strengthened data security.

As shown in FIG. 8B , there is shown a flowchart of processing of the CPU2 with respect to the CPU1 shown in FIG. 8A .

Step 810 , judging whether CPU2 has received an interrupt signal from CPU1 , if yes, go to step 812 , otherwise go to step 814 .

Step 812, CPU2 disconnects the connection with the peripheral device, if CPU2 is processing the player application data, disconnects the connection with the audio processing device.

Step 814, judge whether the current business to be processed by CPU2 needs to use peripherals, for example, need to send pictures to another terminal via Bluetooth, if yes, go to step 816, otherwise end the process.

Step 816, CPU2 connects with Bluetooth.

The above step 812 also includes continuing to connect to the audio device and continue playing music when receiving the notification that the CPU1 has completed the business processing.

For another example, when the display screen is displaying video A (CPU2 is connected to the display screen), a video call is received (CPU1 wants to connect to the display screen), in order to ensure that the user can process the video call in time, CPU1 sends to CPU2 interrupt signal, CPU2 interrupts playing the video A, and when it is determined that CPU2 is disconnected from the display screen, CPU1 establishes a connection with the display screen. After the video call ends, CPU1 notifies CPU2 that the video A can continue to be played. After receiving the notification, CPU2 establishes a connection with the display screen and continues to display video A; in this embodiment, only the display screen is taken as an example, but in practical applications, connection switching of peripheral devices such as touch screens and speakers is also involved.

Therefore, when multiple processors all need to be connected to the same peripheral such as screen, camera, speaker, and WIFI, the processor handling new business can control other processors that are processing other business to interrupt the connection with the corresponding external device. When the processing of the new service is finished, the other processor can be notified that it can continue to connect with the corresponding external device to continue the unfinished service.

It should be understood that the processing unit in the foregoing embodiment may be a complete processor, or a core of a multi-core processor.

The above describes the technical solution of the present invention in detail in conjunction with the accompanying drawings. In the related art, the two communication units of the dual-standby architecture share one processor, and confusion between data is likely to occur, and the private information of the user cannot be effectively obtained. Assure. Therefore, the present invention proposes a new data processing scheme, which can filter private data and non-private data in external devices interacting with the terminal and process them respectively by different processors, avoiding data confusion and ensuring The security of private data improves the user experience.

For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
