As shown in FIG. 2, the system architecture includes a JAVA spatial layer 210, a local framework layer 220, and a kernel space layer 230. The JAVA spatial layer 210 can include a freeze management module 212. The freeze management module 212 can implement a freeze policy for each running application, and freeze the related applications that consume more power in the background or preempt a large amount of system resources. . The resource priority and restriction management module 222 and the platform freeze management module 224 are included in the local framework layer 220.

Save power. The mobile terminal can allocate the application that can be frozen in the background to the frozen layer corresponding to the preset different levels according to the length of the entry freeze time through the platform freeze management module 224. Optionally, the frozen layer may include three: a CPU limited sleep mode, a CPU freeze sleep mode, and a process deep freeze mode. The CPU restricts the sleep mode to limit the CPU resources occupied by the related processes, so that the related processes occupy less CPU resources, and the free CPU resources are tilted to other unfrozen processes, thereby limiting the occupation of CPU resources.

Through the system architecture described above, the information processing method in various embodiments of the present application can be implemented.

As shown in FIG. 3, in an embodiment, an information processing method is provided, including the following operations:

Operation 310, when detecting that the mobile terminal establishes a short-distance connection with other terminals, acquires a registration process of the registered short-distance connection notification running in the background.

Short-distance connection refers to the connection established by short-range wireless transmission technology, and short-range wireless transmission can communicate within a preset distance, which may be 10 meters, 20 meters, and the like. Optionally, the short-range wireless transmission may be one of Bluetooth (BLUETOOTH), infrared or Near Field Communication (NFC), etc., but is not limited thereto. The mobile terminal can establish a short-distance connection with other terminal devices and perform data transmission through the established short-distance connection. For example, the mobile terminal can enable the Bluetooth communication function to pair with other terminals that open the Bluetooth communication function, and after the pairing is successful, the Bluetooth connection can be established with other terminals.

After the mobile terminal establishes a short-distance connection with other terminals, the registration process of registering the distance connection notification running in the background can be obtained. Alternatively, when the mobile terminal detects that a short-distance connection is established with other terminals, the mobile terminal may determine the type of short-range wireless transmission of the connection and acquire registration process information corresponding to the type of the short-range wireless transmission. Different types of short-range wireless transmissions may correspond to different registration process information, and the registration process information may include information such as an identifier, a name, a registration time, and the like of a process of registering a short-range wireless transmission service of a corresponding type, wherein the identifier of the process may be represented by a number. One or more of letters, symbols, and the like. Alternatively, the process can register for short-range wireless transmission services that need to be used. After the registration of the short-range wireless transmission service is successful, the process can receive the notification of the short-range wireless transmission service and can use the short-range wireless transmission service. The notification of the short-range wireless transmission service may include, but is not limited to, establishing a short-distance connection, disconnecting a short-distance connection, and the like. For example, the process registers with the Bluetooth service. After successful registration, the process can receive notifications of Bluetooth and can use Bluetooth for data transmission. The registration process information of different types of short-range wireless transmissions may be recorded in different registries, and the mobile terminal may read the registration process information from the corresponding registry according to the type of short-range wireless transmission of the connection.

The mobile terminal may acquire, according to the registration process information corresponding to the short-distance connection, each registration process registered with the established short-distance connection notification, and obtain a registration process currently running in the background. In an embodiment, the mobile terminal can also obtain a list of all running processes through the activity manager's RunningAppProcessInfo class, and all process lists can include each running process and the running status of each process, wherein the running state It can include foreground running, background running, and so on. The mobile terminal can query in the list of all processes running according to the identifier of the process included in the registration process information, and obtain the registration process running in the background.

Operation 320, determining the status of the registration process when it is detected that the foreground process is performing a preset security operation.

After the mobile terminal establishes a short-distance connection with other terminals, the foreground process running in the foreground can be monitored, and the mobile terminal can collect operation information executed by the foreground process, where the operation information can include operation type, operation content, operation time, and the like. The mobile terminal may determine, according to the operation information executed by the foreground process, whether the foreground process is performing a preset security operation, where the preset security operation refers to a security level operation, such as a payment operation, a transfer operation, etc., but is not limited thereto. Safety operations can be set according to actual needs. When it is detected that the foreground process is performing a preset security operation, the mobile terminal can determine the status of each registration process running in the background. Optionally, the status of the registration process may include a frozen state and a non-freeze state, wherein the frozen state refers to a process incapable of using resources such as CPU, I/O, and network, and is in a state incapable of continuing to run, but the process still occupies Memory resources, hard disk resources, etc.; non-freeze state means that the process can use system resources such as CPU, I/O, memory, and network, and is in a state where it can run execution tasks.

In one embodiment, the mobile terminal can obtain status tags for various registration processes running in the background and determine the status of the registration process based on the status tags. Different states may be represented by different status tags. For example, the status tag corresponding to the frozen state is 0, and the status tag corresponding to the non-freeze state is 1, etc., but is not limited thereto. Optionally, the mobile terminal may also send a communication signal to each registration process running in the background, respectively, and detect whether a response signal is received within a predetermined time period. When the response signal returned by the registration process is not received within the predetermined time period, the mobile terminal may determine that the state of the registration process that did not transmit the response signal is a frozen state. When receiving the response signal returned by the registration process within the predetermined time period, the mobile terminal may determine that the state of the registration process transmitting the response signal is a non-freeze state. It can be understood that the mobile terminal can also determine the status of each registration process running in the background in other manners, and is not limited to the above manners.

Operation 330, when the registration process is in a non-freeze state, freezes the registration process in an unfrozen state.

When the registration process running in the background is in a non-freeze state, the mobile terminal can freeze the registration process in an unfrozen state. After the registration process is frozen, it will no longer continue to run, and resources such as CPU, I/O, and network cannot be used. The frozen registration process cannot receive notifications sent by the registered short-range wireless transmission service, and can no longer use the registered short-range wireless transmission service for data transmission.

In one embodiment, the mobile terminal may detect one by one whether each registration process running in the background is using the established short-distance connection for data transmission, and acquire a registration process that is currently using the short-distance connection for data transmission. Optionally, the mobile terminal may detect whether each registration process running in the background invokes a transmission interface corresponding to the established short-distance connection, thereby determining a registration process that is using the short-distance connection for data transmission. The mobile terminal can freeze only the registration process that is performing data transmission. For other registration processes that run in the background but do not perform data transmission, the registration process may not be frozen, and the execution task is normally performed. It can improve the security of data transmission over short-distance connections, ensure the system responds normally, and reduce the situation that the process is frozen and cannot respond.

In an embodiment, when the mobile terminal detects that the foreground process ends the security operation, the frozen registration process may be thawed. Alternatively, if the foreground process ends the security operation performed, the mobile terminal may continue to collect the foreground process. Operation information, if the foreground process does not perform a new preset security operation within a preset time period, the frozen registration process may be thawed. After the registration process is thawed from the frozen state, you can use system resources such as CPU, I/O, memory, and network to run normally and perform tasks. The thawing registration process can normally receive the notification of the registered short-range wireless transmission service, and can also normally use the short-range wireless transmission service for data transmission.

In this embodiment, when detecting that the mobile terminal establishes a short-distance connection with other terminals, the mobile terminal may acquire a registration process of the registered short-distance connection notification running in the background, when detecting that the foreground process is performing the preset security operation. The mobile terminal can freeze the registration process in the non-freeze state, which can prevent information leakage when data transmission through the short-distance connection, and can improve the security of short-distance wireless transmission.

As shown in FIG. 4, in an embodiment, after the registration process is in a non-freeze state in operation 330, after the registration process in the non-freeze state is frozen, the following operations are also included:

Operation 402, obtaining a process running in the background and having a communication mechanism with the frozen registration process.

After the current station process is performing the preset security operation, after the mobile terminal freezes the registration process that is running in the non-freeze state in the background, the mobile terminal may acquire a process that has a communication mechanism with the frozen registration process running in the background, where Communication mechanisms refer to the propagation or exchange of information between different processes.

Optionally, the communication mechanism may include a socket, a binder, a shared memory, etc., wherein two programs on the network exchange data through a two-way communication connection, one end of the connection is called a socket; the binder is an interprocess Communication mechanism, providing remote procedure call function; shared memory is to allow two unrelated processes to access the same logical memory, shared memory is a very effective way to share and transfer data between two running processes, different The memory shared between processes is usually arranged in the same piece of physical memory. Optionally, the mobile terminal may detect whether there is a process that has at least one of socket and binder communication with the frozen registration process, and determine that the process with at least one of socket and binder communication with the frozen registration process is determined to have The process of the communication mechanism. The mobile terminal can also detect whether there is a process for memory sharing with the frozen registration process, and determine a process that performs memory sharing with the frozen registration process as a process having a communication mechanism.

Operation 404 freezes the process with the communication mechanism.

After the mobile terminal acquires a process running in the background and has a communication mechanism with the frozen registration process, the state of each process having the communication mechanism can be acquired. When the process with the communication mechanism is in a non-freeze state, the mobile terminal can freeze the process with the communication mechanism. After the process with the communication mechanism is frozen, it will no longer be able to continue running, and resources such as CPU, I/O, and network cannot be used.

In an embodiment, when the mobile terminal detects a security operation in which the foreground process ends execution, the mobile terminal unfreezes the frozen registration process, and simultaneously freezes the frozen process having the communication mechanism with the registration process. After the process with the communication mechanism is thawed, the process with the communication mechanism can normally communicate with the thawed registration process.

In this embodiment, the mobile terminal may freeze the process with the communication mechanism of the frozen registration process, thereby preventing the frozen registration process from being woken up, causing information leakage, and further improving the security of short-range wireless transmission.

As shown in FIG. 5, in one embodiment, after the operation of acquiring the registration short-distance connection notification running in the background, the following operations are also included:

Operation 502, obtaining an operational characteristic of the registration process.

After the mobile terminal acquires each registration process running in the background, the running characteristics of each registration process can be obtained. The operational characteristics may include, but are not limited to, tasks currently performed by the registration process, communication events with other processes, current resource types and ratios, and the like.

Operation 504, determining a resource restriction level of the registration process according to the operational characteristics.

The mobile terminal can analyze the running characteristics of the registration process and determine the resource restriction level of the registration process according to the running characteristics. Optionally, the mobile terminal may set different resource restriction levels according to actual requirements. The resource restriction level may be used to indicate the extent to which the used resources are restricted. The higher the resource restriction level, the greater the degree of restriction. Restricted resources may include, but are not limited to, CPU resources, memory resources, I/O resources, network resources, and the like. Different resource restriction levels may correspond to different resource usage priorities. The higher the resource restriction level, the smaller the corresponding resource usage priority, and the lower the resource restriction level, the greater the corresponding resource usage priority.

In an embodiment, the resource restriction level set by the mobile terminal may include an unrestricted level, a normal restriction level, a depth restriction level, and a freeze level. An unrestricted level can mean that resources used by a process are not restricted. The normal restriction level may refer to a process that can use fewer resources, such as up to 50% of resources, but is not limited thereto. The depth limit level can mean that the process can use very few resources, such as up to 20% of resources, but not limited to this. The freeze level refers to the process that cannot use any resources to stop all actions of the process. For example, when the registration process uses the established short-distance connection for data transmission, it can correspond to an unrestricted level; when the registration process does not use the short-range wireless transmission service, and only communicates with other registration processes that perform short-range wireless data transmission, It can correspond to the normal restriction level; when the registration process does not use the short-range wireless transmission service, and only communicates with other processes that do not perform short-range wireless data transmission, it can correspond to the depth resource restriction level, etc.; when the registration process is not used When the short-range wireless transmission service does not communicate with other processes, it can correspond to the freeze level, etc., but is not limited thereto.

In operation 506, the registration process is allocated to the resource group corresponding to the resource restriction level, and the resource usage priority corresponding to the resource restriction level is configured.

After the mobile terminal determines the resource restriction level of the registration process, the registration process may be allocated to the resource group corresponding to the determined resource restriction level, and the resource usage priority corresponding to the resource restriction level may be configured. Optionally, the mobile terminal may divide different resource groups based on a kernel Cgroup (control group) mechanism, and set a resource usage priority of each resource group by using a file node write configuration manner, and is allocated to each resource group. The process in the process is managed by the time or proportion of the resource. The Cgroup is a mechanism provided in the kernel that can limit, record, and isolate the physical resources used by the process (such as CPU, memory, I/O, etc.). . The mobile terminal can load a Cgroup configuration file, and the configuration file can record the divided resource groups, the resource usage priorities of the resource groups, and the resource scheduling policies corresponding to the resource usage priorities. The resource scheduling policy may include, but is not limited to, the time allocated by the process allocated to the resource group, the proportion of occupied resources, the resource identifier used, and the like. For example, the process of configuring the resource group corresponding to the common restriction level is within 1 minute. The CPU resource of 30 seconds can be used, and the process of the resource group corresponding to the common restriction level can only use the CPU resource numbered X, but is not limited thereto. When it is necessary to add a new resource group or modify the resource usage priority and resource scheduling policy of the resource group, the mobile terminal can modify the configuration file of the Cgroup.

After the mobile terminal allocates the registration process to the resource group corresponding to the resource restriction level and configures the resource usage priority corresponding to the resource restriction level, the registration process may use the CPU, the memory, and the resource scheduling policy corresponding to the resource group. Resources such as I/O and network. In an embodiment, the mobile terminal may acquire the running characteristics of each registration process that registers the current short-distance connection notification at regular intervals, and determine the resource restriction level of the registration process according to the running characteristics. The resource restriction level of the registration process can change as the operational characteristics change. For example, after the registration process ends short-range wireless data transmission, the mobile terminal can increase the resource restriction level of the registration process and reduce the resource usage priority of the registration process; after the registration process starts using the short-distance connection for data transmission, the mobile terminal can be reduced. The resource restriction level of the registration process, the resource usage priority of the registration process, etc., but is not limited thereto.

Optionally, when the mobile terminal detects that the foreground process is performing the preset security operation, the mobile terminal may freeze the registration process in the non-freeze state in the background running, and may add and freeze the registration process in the non-freeze state. The resource group corresponding to the level is configured with the resource usage priority corresponding to the resource group.

Figure 6 is a schematic diagram of a resource group in one embodiment. As shown in FIG. 6, four different resource restriction levels can be set in the mobile terminal, and four resource groups are divided, wherein the first resource group corresponds to an unrestricted level, and the second resource group corresponds to an ordinary limit. Level, the third resource group corresponds to the depth limit level, and the fourth resource group corresponds to the freeze level. The four resource groups may respectively correspond to different resource usage priorities, the resource usage priority of the first resource group may be higher than the second resource group, and the resource usage priority of the second resource group may be higher than the third resource. In the group, the resource usage priority of the third resource group may be higher than the fourth resource group. The first resource group at an unrestricted level does not limit resources such as CPU, memory, I/O, and network used by the process. The second resource group restriction process of the normal restriction level can use less resources such as CPU, memory, I/O, and network. The third resource group limit process at the depth limit level uses very few resources such as CPU, memory, I/O, and network. The fourth resource group restriction process at the freeze level cannot use resources such as CPU, memory, I/O, and network. The mobile terminal determines the resource restriction level according to the running characteristics of the registration process, and adds the registration process to the corresponding resource group to configure the resource usage priority corresponding to the resource group, and manages the resources used by the registration process.

In this embodiment, the mobile terminal may determine the resource restriction level according to the running characteristics of the registration process, dynamically implement different levels of resource restrictions on the registration process, optimize system performance, and save power consumption.

As shown in FIG. 7, in an embodiment, the foregoing information processing method further includes the following operations:

At operation 702, the running characteristics of the registration process are collected through the kernel space, and the running features are packaged into data packets and transmitted to the user space.

The virtual space of the mobile terminal may include kernel space and user space, the kernel space may be used to store the code and data of the kernel, and the user space may be used to store the code and data of the application. Kernel space has a high privilege level. Processes running in kernel space can have access to all hardware of the mobile terminal. User space has lower permissions. Processes running in user space can only use some resources of the system.

The mobile terminal can collect event data of each registration process running in the background through the kernel space, and the event data can include, but is not limited to, an event type, an event time, an event content, a target identifier to which the event belongs, and the like. Event types can include, but are not limited to, communication events, create events, exit events, change identification events, task events, and the like. Communication events may include binder communication events and socket communication events. Creating an event can refer to an event created by a process or thread. An exit event refers to an event that is exited by an application, process, or thread. A change identification event can refer to a process or a thread that changes its own identity, and the like. A task event can refer to a task, such as an application, a process, or a thread.

Optionally, the mobile terminal may collect event data of different event types for different registration processes. The mobile terminal may pre-determine the type of the event to be collected and the corresponding process identifier. For example, the process of collecting the binder communication event may be pre-determined, or the application or process for collecting the socket communication event may be pre-defined. Different event types can correspond to different process identifiers.

The mobile terminal collects event data of each registration process through the kernel space, extracts running characteristics of each registration process from the event data, and packages the running characteristics into data packets and transmits the data to the user space according to the agreed packet format. Optionally, the kernel space and the user space can communicate by means of an asynchronous netlink, which is a special inter-process communication that enables the user process to communicate with the kernel process. The kernel space transmits the running characteristics of each registration process to the user space through asynchronous communication, which is faster and more convenient than the active query mode of the user space, and can improve the transmission efficiency of the running features.

Operation 704, parsing the data packet through the user space, and obtaining an operation feature of the registration process.

Operation 706, analyzing the running characteristics through the user space, and determining a resource restriction level of the registration process.

After the user space receives the data packet transmitted by the kernel space, the data packet can be parsed to obtain the running characteristics of each registration process. The mobile terminal can analyze the running characteristics of each registration process through the user space, and determine the resource restriction level of each registration process.

In this embodiment, the mobile terminal can collect the running features of each registration process running in the background through the kernel space, and transmit the collected running features to the user space for analysis, and the mobile terminal can provide more clues for determining the resource restriction level. It can make the resource restriction level adjustment of the registration process more accurate, improve resource management effect and system performance.

As shown in FIG. 8, in an embodiment, the information processing method further includes the following operations:

Operation 802, transmitting a termination signal through the user space.

When the mobile terminal needs to terminate a running process, the termination signal can be sent through the user space, and the termination signal can be used to terminate the running of the process, causing the process to exit and release the occupied system resources such as CPU and memory.

In operation 804, the termination signal is intercepted, and when the target process of the termination signal is in a frozen state, the target process and each thread included in the target process are thawed.

The mobile terminal intercepts the termination signal sent by the user space and determines whether the target process of the termination signal is in a frozen state. When the target process is not in the frozen state, the mobile terminal can directly send the termination signal to the target process, and the target process can respond to the termination signal to terminate the operation of the target process. When the target state is in a frozen state, the process that is in the frozen state cannot receive the signal sent by other processes normally, and therefore does not respond normally to the termination signal. In the traditional way, it is usually necessary to write two sets of different codes, which are used to terminate the frozen state process and the non-freeze state process, which poses a major obstacle to the development and maintenance of the system. After the mobile terminal intercepts the termination signal, when the target process of the termination signal is in a frozen state, the mobile terminal may first send a defrosting signal to the target process, and thaw the target process and each thread included in the target process. Unfreezing the target process and all the threads included in the target process can prevent the zombie process from being wasted, causing waste of system resources. The zombie process refers to the fact that although the process has exited, some exits are reserved for it in the system process table. Status information, which occupies the process table entry.

Operation 806, setting the target process to a non-freeze state, and sending a termination signal to the target process, and the termination signal is used to terminate the target process.

After the mobile terminal unfreezes the target process and each thread included in the target process, the target process can be set to a non-frozen state, and the unfrozen state refers to that the target process cannot be frozen again. The mobile terminal can send the termination signal to the target process. Since the target process is in an unfrozen state at this time, the termination signal can be normally responded, the target process is terminated, the target process is exited, and the occupied CPU, memory, and the like are released. Resources.

In this embodiment, the mobile terminal can safely terminate the process in the frozen state without the occurrence of a zombie process.
