Based on the above terminal hardware structure and communication network system, the present invention provides various embodiments of the mobile terminal restart positioning method.

The invention provides a mobile terminal restart positioning method.

Referring to fig. 3, fig. 3 is a flowchart illustrating a method for restarting and positioning a mobile terminal according to a first embodiment of the present invention.

In the present embodiment, an embodiment of a method for restarting a location by a mobile terminal is provided, and it should be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that here.

In this embodiment, the method for restarting and positioning a mobile terminal includes:

step S10, when it is monitored that a register at a position corresponding to a preset key information point in the Kernel layer Kernel memory trust area management module of the mobile terminal is in an abnormal state, reading an abnormal identifier corresponding to the register.

The method mainly aims at the scene that a trust area register is needed to be used in a Kernel layer Kernel memory trust area management module of the mobile terminal, in the Kernel memory trust area management module, the mobile terminal marks each register interval corresponding to the Kernel layer as a trust area, and specifically, the mobile terminal determines the trust area according to a starting address and an end address corresponding to the Kernel layer in each register. Registers include, but are not limited to, data registers, address pointer and index registers, control register sets, and segment registers. After the mobile terminal determines the register in the trust area, the mobile terminal determines that the calling process and/or the time sequence logic of the corresponding module of the register scene of the trust area need to be used, and standardizes the calling process and/or the time sequence logic, namely key information points are set in main function nodes of the calling process and/or the time sequence logic, so that the calling process and the internal basic function time sequence logic which are standardized correspondingly to the Kernel memory trust area management module are obtained. The Kernel layer is a system Kernel layer of the mobile terminal, and is mainly used for performing related work such as initialization process management, memory management, Display loading, Camera Driver and Binder Driver, and creating Kernel daemon processes such as Kernel work thread kworkder, soft interrupt thread ksofirqd and soft interrupt thread thermal.

When the mobile terminal monitors that a register at a position corresponding to a preset key information point in a Kernel layer Kernel memory trust area management module of the mobile terminal is in an abnormal state, the mobile terminal reads an abnormal identifier corresponding to the register. The key information points are information points which are preset in a calling process corresponding to the Kernel memory trust area management module and internal basic function time sequence logic and are used for monitoring whether the calling process and the time sequence logic are in abnormal states. When the registers of the key information points corresponding to the call flows and/or the sequential logic are monitored to be in the abnormal state, the corresponding call flows and/or the sequential logic are confirmed to be in the abnormal state. And the exception identifier corresponding to the register is preset and is used for indicating the identifier that the register is in an exception state. It should be noted that the exception identifications of the registers corresponding to different key information points are different. The setting rule of the register exception identifier can be set according to specific requirements, and registers corresponding to different key information points can be identified. In this embodiment, the trust area register being in an exception state may be denoted a CRED register exception.

Further, referring to fig. 4, step S10 includes:

step S11, when detecting that a monitoring instruction of a key information point is preset in the Kernel layer Kernel memory trust area management module of the monitoring mobile terminal, reading the state value of the key information point according to the monitoring instruction.

And step S12, determining whether the register of the corresponding position of the key information point is in an abnormal state according to the state value.

In step S13, if the register is in an abnormal state, the abnormal flag corresponding to the register is read.

When the mobile terminal detects a monitoring instruction for monitoring a preset key information point in a Kernel layer Kernel memory trust area management module of the mobile terminal, reading a state value of the preset key information point according to the monitoring instruction, and determining whether a register at a position corresponding to the preset key information point is in an abnormal state or not according to the state value. And if the register at the position corresponding to the key information point is determined to be in an abnormal state according to the state value, the mobile terminal reads the abnormal identifier corresponding to the register. If the register at the position corresponding to the key information point is determined to be in a normal state according to the state value, the register is indicated to have no corresponding abnormal identifier, and the mobile terminal cannot read the abnormal identifier corresponding to the register.

Wherein, the state value and the abnormal state have corresponding relation. In this embodiment, the corresponding relationship between the state value and the abnormal state may be limited according to specific needs, and is not limited herein. If the state value corresponding to a certain key information point is set to be 0, determining that the register at the corresponding position of the key information point is in a normal state; and when the state value corresponding to a certain key information point is 1, determining that the register at the position corresponding to the key information point is in an abnormal state. In the present embodiment, the register being in an exception state may be understood as a register exception.

And step S20, matching the abnormal mark with the pre-stored log mark.

Step S30, if the matching between the abnormal mark and the log mark is successful, the log information associated with the log mark is searched according to the log mark, and the process information of the process corresponding to the register is obtained.

And after the abnormal identifier corresponding to the register is obtained, the mobile terminal triggers a matching instruction for matching the obtained abnormal identifier with the log identifier stored in the storage restart operation reason database. And after the matching instruction is triggered, the mobile terminal matches the abnormal identifier with the log identifier according to the matching instruction. If the abnormal identifier is successfully matched with the log identifier, the mobile terminal searches the log information associated with the log identifier in a database storing the restart operation reason according to the log identifier and acquires the process information of the process corresponding to the register. It should be noted that the log identifier is an identifier corresponding to log information that causes the restart operation of the mobile terminal. The log information includes, but is not limited to, a name of a node in which a register exception occurs in the Kernel memory trusted zone management module and a location in which the register exception occurs in the Kernel memory trusted zone management module. The process information includes, but is not limited to, when the register is in an abnormal state, the name of the corresponding process, that is, the name of the process involved in the process, the name of the associated thread, the ID (identification) and the thread ID of the process involved in the process or the associated process, and the function node of the Kernel memory trusted area management module corresponding to the key information point.

In this embodiment, when the abnormal identifier is consistent with the pre-stored log identifier, it is determined that the abnormal identifier is successfully matched with the pre-stored log identifier; and if the abnormal identifier is inconsistent with the pre-stored log identifier, confirming that the abnormal identifier is failed to be matched with the pre-stored log identifier. If the abnormal identifier is a, the log identifier which is the identifier a is found in the database, the matching between the abnormal identifier and the pre-stored log identifier is confirmed to be successful, otherwise, the matching between the abnormal identifier and the pre-stored log identifier is confirmed to be failed. In other embodiments, it may be set that when the abnormal identifier is associated with the pre-stored log identifier, it is determined that the abnormal identifier is successfully matched with the pre-stored log identifier, and otherwise, it is determined that the abnormal identifier is unsuccessfully matched with the pre-stored log identifier. If the log identifier set to be associated with the exception identifier a1 is a2, if the exception identifier of the corresponding register of a certain key information point is a1 and the log identifier identified as a2 is found in the database, it is determined that the exception identifier is successfully matched with the pre-stored log identifier, otherwise, it is determined that the exception identifier is unsuccessfully matched with the pre-stored log identifier.

And step S40, generating a restart log according to the process information and the log information, so as to locate the restart reason of the mobile terminal according to the restart log.

After the process information and the log information are acquired, the mobile terminal generates a restart log according to the process information and the log information and outputs the restart log to a specified position, so that corresponding workers can quickly acquire the restart log after the restart operation of the mobile terminal occurs, and the restart reason causing the restart operation of the mobile terminal is quickly determined according to the restart log.

Further, in the process of generating the restart log according to the process information and the log information, the mobile terminal generates the restart log according to a specific format, so that a corresponding worker can quickly analyze the reason of the restart operation of the mobile terminal according to the restart log.

Further, the method for restarting and positioning the mobile terminal further comprises the following steps:

step a, determining whether a position register corresponding to the monitoring key information point is in a thread corresponding to the monitoring instruction in an abnormal state, and deploying the thread in a Kthreded process and a Kernel process of a Kernel layer.

Furthermore, when the mobile terminal deploys the Kernel layer process, the mobile terminal determines a monitoring instruction corresponding thread for monitoring whether a register at a position corresponding to a preset key point of the Kernel layer Kernel memory trust area management module is in an abnormal state, and deploys the thread corresponding to the monitoring instruction in the ktreaded process and the Kernel process of the Kernel layer, so that whether the register in the Kernel layer Kernel memory trust area management module is in the abnormal state can be monitored in the whole process. It should be noted that the thread corresponding to the monitoring instruction is independently run in the mobile terminal.

In the embodiment, when the condition that a register at a position corresponding to a preset key information point in a Kernel layer Kernel memory trust area management module of the mobile terminal is in an abnormal state is monitored, an abnormal identifier corresponding to the register is read; matching the abnormal identifier with a pre-stored log identifier; if the abnormal identifier is successfully matched with the log identifier, searching log information associated with the log identifier according to the log identifier, and acquiring process information of a process corresponding to the register; and generating a restart log according to the process information and the log information so as to locate the restart reason of the mobile terminal according to the restart log. The method and the device have the advantages that the restart log corresponding to the restart operation of the mobile terminal is obtained in advance before the restart operation of the mobile terminal does not occur, so that corresponding workers can quickly determine the reason causing the restart of the mobile terminal according to the restart log after the restart operation of the mobile terminal occurs, the efficiency of locating the restart reason of the mobile terminal is improved, and the labor cost is reduced.

Further, a second embodiment of the method for restarting the positioning of the mobile terminal is provided based on the first embodiment. The difference between the second embodiment of the method for restarting the location of the mobile terminal and the first embodiment of the method for restarting the location of the mobile terminal is that the step of reading the state value of the key information point according to the monitoring instruction comprises the following steps:

and b, reading a preset number of first state values of the key information points according to the monitoring instruction and the first reading frequency.

And c, if the register is determined to be in the normal state according to the first state values of the preset number, reading the second state values of the preset number of the key information points according to the second reading frequency.

And d, if the register is determined to be in the normal state according to the preset number of second state values, reading a third state value of the key information point according to a third reading frequency, wherein the second reading frequency is greater than the first reading frequency and less than the third reading frequency.

The process of the mobile terminal reading the state value of the key information point according to the monitoring instruction is as follows: and the mobile terminal reads the first state values of the preset number of the key information points according to the monitoring instruction and the first reading frequency, and judges whether the read first state values of the preset number can determine that the register is in a normal state or not. If the read first state values of the preset number can determine that the register is in the normal state, reading second state values of the preset number of the key information points according to a second reading frequency, and judging whether the read second state values of the preset number can determine that the register is in the normal state. If the read second state values of the preset number can determine that the register is in the normal state, reading third state values of the preset number of the key information points according to a third reading frequency, and determining whether the register at the corresponding position of the key information points is in the abnormal state or not according to the third state values.

The second reading frequency is greater than the first reading frequency and less than the third reading frequency. The first reading frequency, the second reading frequency, the third reading frequency and the preset number can be set according to specific needs, for example, the first reading frequency can be set to be read every 1 second, the second reading frequency can be set to be read every 3 seconds, the third reading frequency can be set to be read every 5 seconds, and the preset number can be set to be 5. Namely, after the mobile terminal continuously reads the state values at 1 second intervals for 5 times according to the monitoring instruction, the state values corresponding to the key information points are continuously read for 5 times at intervals of 3 seconds, if the 5 state values read at intervals of 3 seconds indicate that the register is in the normal state, the state values corresponding to the key information points are continuously read for 5 times at intervals of 5 seconds, and whether the register at the corresponding position of the key information point is in the abnormal state is determined according to the 5 state values continuously read at intervals of 5 seconds.

It should be noted that, in other embodiments, the reading frequency for setting the status value of the read key information point may be increased, for example, if 5 status values read continuously every 5 seconds indicate that the register is in the normal state, the status value corresponding to the key information point is read continuously 5 times every 8 seconds. This is not limited in the present embodiment.

and e, if the register is determined to be in an abnormal state according to the first state value, detecting whether the mobile terminal is restarted.

And f, if the mobile terminal is not restarted, reading the state value of the key information point according to a fourth reading frequency.

Further, if the register is determined to be in an abnormal state according to one first state value in the process of reading the preset number of first state values of the key information points according to the monitoring instruction and the first reading frequency, the mobile terminal detects whether the reset operation occurs. And if the mobile terminal is not subjected to the restarting operation, the mobile terminal reads the state value of the key information point according to the fourth reading frequency. Further, if the mobile terminal is restarted, it indicates that the mobile terminal has been initialized, and the mobile terminal detects whether a monitoring instruction for monitoring a state value of a key information point preset in a Kernel layer Kernel memory trust area management module of the mobile terminal is detected. The fourth reading frequency can be set according to specific needs, and if the fourth reading frequency is set to be equal to the first reading frequency, the fourth reading frequency and the first reading frequency are set to be read once every 1 second; or set to be unequal to the first reading frequency, such as setting the fourth reading frequency to be read every 0.8 seconds, or every 2 seconds.

For ease of understanding, the process is illustrated: when the mobile terminal continuously reads the state value of the key information point for 5 times at intervals of 1 second according to the monitoring instruction, if the register at the corresponding position is determined to be in an abnormal state according to the state value of the key information point read at the 3 rd second and the mobile terminal is not restarted, the mobile terminal reads the state value of the key information point once at intervals of 0.8 (at this time, the fourth reading frequency is set to be 0.8 second reading time).

It is understood that, if the register is determined to be in the abnormal state according to a second state value or a third state value, the mobile terminal detects whether a restart operation occurs.

In this embodiment, by setting the reading frequency for reading the key information points, when the register at the corresponding position of the key information point of the Kernel memory trust area management module is in the normal state, the reading frequency for reading the state values of the key information points is increased, so that when the register is in the normal state, the number of times for reading the state values of the key information points is reduced.

Further, a third embodiment of the method for restarting the positioning of the mobile terminal is provided based on the first embodiment. The third embodiment of the mobile terminal relocation method differs from the first and/or second embodiment of the mobile terminal relocation method in that, with reference to fig. 5, the mobile terminal relocation method further includes:

step S50, storing the restart log, and determining the restart log stored in the second preset time.

In step S60, a redundancy removing operation is performed on the log information stored in the second preset time to save the storage space.

And after the restart log is generated, the mobile terminal stores the restart log, determines the restart log stored in the second preset time, and executes redundancy removal operation on the restart log stored in the second preset time so as to save the storage space of the mobile terminal. Specifically, during the redundancy removing operation, only one restart log belonging to the same type of restart operation is stored, other restart logs corresponding to the stored type of restart operation are deleted, the number of the restart logs belonging to the same type of restart operation and whether the corresponding register has been changed from the abnormal state to the normal state are correspondingly recorded, and the transition time of the register from the abnormal state to the normal state is recorded. The second preset time can be set according to specific needs, for example, the second preset time can be set to 45 minutes, 60 minutes, or 100 minutes, etc. It should be noted that, in the process of performing classified storage on the restart log, the restart log may be classified and stored according to the reason of the restart, or may be classified according to the location of the restart, which is not limited herein.

For example, the register exception occurs when the mobile terminal is within 60 minutes from 10 o 'clock to 11 o' clock, and a total of 1000 restart logs are stored in the mobile terminal. At this time, the mobile terminal classifies restart logs of restart operations belonging to the same category into one category before the register is changed from the abnormal state to the normal state. If 520 restart logs correspond to the A1 restart operations, 360 restart logs correspond to the B1 restart operations, and 120 restart logs correspond to the C1 restart operations, only one restart log corresponding to the A1 restart operations is stored, the restart logs corresponding to the rest 519 restart operations of the A1 are deleted, and the number of the restart logs corresponding to the A1 restart operations is recorded as 520; storing a restart log corresponding to B1-type restart operations, deleting the rest 359 restart logs corresponding to B1-type restart operations, and recording the number of the restart logs corresponding to B1-type restart operations as 360; storing a restart log corresponding to the C1 type restart operation, deleting the rest 119 restart logs corresponding to the C1 type restart operation, and recording the number of the restart logs corresponding to the C1 type restart operation as 120.

It should be noted that the solution of the redundancy elimination operation may also be applicable to process information and log information, and when the redundancy elimination operation is performed on the process information and the log information, the specific operation process is consistent with the redundancy elimination operation process performed on the restart log, which is not described herein again.

In the embodiment, redundancy removal operation is performed on the restart log stored in the second preset time, so that the storage space of the mobile terminal is saved.

and g, judging whether the register of the corresponding position of the key information point is monitored again in the abnormal state within the first preset time after the process information is acquired.

And h, if the register of the corresponding position of the key information point is monitored to be in an abnormal state again in the first preset time, storing the process information.

Further, after the mobile terminal acquires the process information, the mobile terminal determines whether the register at the position corresponding to the key information point is monitored again to be in an abnormal state within a first preset time after the process information is acquired. If the register of the corresponding position of the key information point is monitored to be in an abnormal state again within the first preset time, the mobile terminal stores the process information so as to generate a restart log according to the process information. Further, if the register at the position corresponding to the key information point is not monitored to be in the abnormal state again within the first preset time, the mobile terminal deletes the acquired process information. The first preset time can be set according to specific needs, for example, the first preset time can be set to 3 minutes, 5 minutes, or 8 minutes.

Further, in the process of storing the process information, the mobile terminal determines the acquisition time of acquiring the process information, stores the process information from front to back according to the acquisition time, and arranges the last acquired process information in the front.

In this embodiment, whether to store the process information is determined by determining whether to monitor that the register is in the abnormal state again within the first preset time, so as to control the amount of the stored process information, thereby saving the storage space of the mobile terminal.

Further, a fourth embodiment of the method for restarting the positioning of the mobile terminal according to the present invention is provided based on the first embodiment. The fourth embodiment of the mobile terminal restart location method differs from the first and/or second embodiment of the mobile terminal restart location method in that, referring to fig. 6, the mobile terminal restart location method further includes:

step S70, determining an identification node, a loading node, an operation node, an instruction allocation node, a cross-process data communication node, an unloading node, a memory resource application and release node and a disk read-write operation node of a Kernel memory trust area management module calling process in a Kernel layer.

And step S80, setting key information points in the identification node, the loading node, the operation node, the instruction allocation node, the cross-process data communication node, the unloading node, the memory resource application and release node and the disk read-write operation node.

The method aims to accurately and quickly locate the reason for restarting the Kernel memory trust area management module in the Kernel layer of the mobile terminal. The method comprises the steps that a mobile terminal determines an identification node, a loading node, a running node, an instruction allocation node, a cross-process data communication node, an unloading node, a memory resource application and release node and a disk read-write operation node of a call flow of a Kernel memory trust area management module in a Kernel layer, and sets key information points in the identification node, the loading node, the running node, the instruction allocation node, the cross-process data communication node, the unloading node, the memory resource application and release node and the disk read-write operation node so as to monitor whether a register of a corresponding node is in an abnormal state or not through the key information points. It can be understood that the identification node, the loading node, the running node, the instruction allocation node, the cross-process data communication node, the unloading node, the memory resource application and release node, and the disk read-write operation node are important nodes in the call flow of the Kernel memory trust area management module. The frequency control node is a frequency control node of the register.

Further, in order to quickly locate a restart reason of the mobile terminal when a restart operation occurs, the mobile terminal determines a time sequence logic of each function in the Kernel memory trust area management module, and sets a key information point in each function node corresponding to the time sequence logic. For example, the time sequence logic of a certain function in the Kernel memory trust area management module is as follows: a → B → C → D, then set key information points at node A, node B, node C and node D, respectively.

It can be understood that, because the key information points are set in the call flow and the time sequence logic of the service corresponding to the different modules of the mobile terminal, after the restart operation of the mobile terminal is determined, the type of the restart operation can be determined according to the key information points, that is, it is determined that the restart operation of the mobile terminal is caused by an abnormality in a Java framework layer, a Native framework layer, or a Kernel memory trust region management module in a Kernel layer.

In the embodiment, key information points are set at an identification node, a loading node, an operation node, an instruction allocation node, a cross-process data communication node, an unloading node, a memory resource application and release node and a disk read-write operation node of a calling process of a Kernel memory trust area management module, and whether a corresponding register is in an abnormal state is judged by monitoring each key information point in the Kernel memory trust area management module so as to locate a restart reason of a restart operation of an important node in the mobile terminal Kernel memory trust area management module calling process.

In addition, the embodiment of the invention also provides a computer readable storage medium.

The computer readable storage medium has a mobile terminal restart positioning program stored thereon, and the mobile terminal restart positioning program when executed by a processor implements the following steps:

when a monitoring instruction for monitoring key information points preset in a Kernel layer Kernel memory trust area management module of the mobile terminal is detected, reading state values of the key information points according to the monitoring instruction;

Further, after the step of reading the preset number of first state values of the key information points according to the monitoring instruction and the first reading frequency, the mobile terminal restart positioning program, when executed by the processor, implements the following steps:

Further, before the step of generating a restart log according to the process information and the log information to locate the restart reason of the mobile terminal according to the restart log, the mobile terminal restart location program implements, when executed by a processor, the steps of:

Further, after the step of generating a restart log according to the process information and the log information to locate the restart reason of the mobile terminal according to the restart log, the mobile terminal restart location program when executed by the processor implements the steps of:
