With continued reference to fig. 2, fig. 2 is an internal framework diagram of the mobile terminal according to the embodiment of the present invention.

The mobile terminal has a dual-chip system, and performs packet sharing between the chip systems, and the following description will be given by taking the case where the packet is an upgrade packet as an example.

In this embodiment, the mobile terminal includes:

the first application processor 10 is used for sending an upgrading instruction to the second application processor 20 when the upgrading packet is obtained;

when the system where the second application processor 20 of the mobile terminal is located needs to be upgraded, the first application processor 10 acquires an upgrade package. When the first application processor 10 acquires the upgrade package, the first application processor 10 transmits an upgrade instruction to the second application processor 20. The first application processor 10 and the second application processor 20 perform data transmission through a universal serial bus. Mobile terminals include, but are not limited to, smart phones and ipads. The first application processor 10 may obtain The upgrade package through FOTA (Firmware Over-The-Air) upgrade, or copy The upgrade package to a specified directory of The mobile terminal, such as an SD (Secure Digital Memory Card) Card directory or a data directory. FOTA is an over-the-air software of a mobile terminal, and refers to a device with a networking function by a cloud upgrading technology: for example, a mobile phone, a tablet computer, a portable media player, a mobile internet device and the like provide firmware upgrading services, a user obtains an intelligent terminal system upgrading package in an on-demand and easily-extensible manner by using a network, and cloud upgrading is performed through FOTA to complete system repair and optimization.

Further, when the first application processor 10 acquires the upgrade package, the version number of the upgrade package is acquired from the upgrade package. The first application processor 10 sends an obtaining instruction to the second application processor 20, and when the second application processor 20 receives the obtaining instruction sent by the first application processor 10, the second application processor obtains the version number of the system where the second application processor is located before upgrading according to the obtaining instruction, and sends the version number of the system where the second application processor is located before upgrading to the first application processor 10. When the first application processor 10 receives the version number which is not updated and sent by the second application processor 20, the version number which is not updated and is of the system where the second application processor 20 is located is compared with the version number of the upgrade package, and when the first application processor 10 determines that the version number which is not updated and is of the system where the second application processor 20 is located is lower than the version number of the upgrade package, it is determined that the system where the second application processor 20 is located needs to be upgraded. When the first application processor 10 determines that the version number of the system where the second application processor 20 is located before the upgrade is the same as the version number of the upgrade package, it is determined that the system where the second application processor 20 is located does not need to be upgraded.

The second application processor 20 is configured to receive an upgrade instruction, and share the storage interval to the first application processor 10 according to the upgrade instruction;

the first application processor 10 is further configured to share the upgrade package to the second application processor 20 through the storage interval when the storage interval is detected;

the second application processor 20 receives the upgrade instruction sent by the first application processor 10, and shares the storage interval to the first application processor 10 according to the upgrade instruction. When the first application processor 10 detects the storage interval shared by the second application processor 20, the upgrade package is shared to the second application processor 20 through the storage interval. That is, the second application processor 20 shares the built-in SD card directory to the first application processor 10 through USB, and when the first application processor 10 detects the SD card of the second application processor 20, copies the upgrade package to the SD card in the second application processor 20.

And the second application processor 20 is further configured to perform system upgrade according to the upgrade package when the upgrade package is detected.

When the second application processor 20 detects the upgrade package in its memory section, the memory section shared to the first application processor 10 is reclaimed and the first application processor 10 is no longer in control of the SD card of the second application processor 20. The second application processor 20 enters a recovery mode, performs upgrading according to the upgrade package stored in the SD card, and sends upgrade information to the first application processor 10 to notify the first application processor 10 that the second application processor 20 has started upgrading according to the upgrade package. Recovery mode refers to a mode in which data or systems inside the android can be modified. In the Recovery mode, a new android system can be refreshed, or an existing system can be backed up or upgraded, and factory settings can be restored at the same time.

Further, when the second application processor 20 is upgraded successfully, the first application processor 10 deletes the upgrade package. If the system where the first application processor 10 is located needs to be upgraded, the first application processor 10 downloads the upgrade package required by the upgrade again, and performs system upgrade according to the downloaded upgrade package again. Further, after the system upgrade of the first application processor 10 is successful, the first application processor 10 obtains the version number of the system after the system upgrade and compares the version number of the system after the system upgrade with the version number of the upgrade package downloaded again. If the version number of the system where the first application processor 10 is located after the system upgrade is the same as the version number of the upgrade package, it indicates that the system where the first application processor 10 is located is upgraded successfully; if the version number of the system in which the first application processor 10 is located after the system upgrade is different from the version number of the upgrade package, it indicates that the system upgrade in which the first application processor 10 is located fails. When the system in which the first application processor 10 is located is upgraded successfully, the first application processor 10 deletes the upgrade package downloaded again, so as to save the storage space; when the system in which the first application processor 10 is located fails to be upgraded, the first application processor 10 acquires the upgrade package again to perform system upgrade, and if the system in which the first application processor 10 is located fails to be upgraded again, the first application processor 10 sends the reason of the system upgrade failure to the server, so that a manufacturer of the upgrade package can improve the upgrade package according to the reason of the upgrade failure.

It should be noted that the data package may also be an installation package. When the data package is an installation package, the sharing of the installation package between the first application processor 10 and the second application processor 20 is similar to the sharing of the upgrade package, and is not described herein again.

In the embodiment, when the first application processor 10 acquires the upgrade package, the upgrade package is sent to the second application processor 20, and when the second application processor 20 receives the upgrade package, the system is upgraded according to the upgrade package. The upgrading problem of the system where the second user identification card 11 is located in the dual-card dual-pass mobile terminal is solved.

In this embodiment, the dual-card dual-channel mobile terminal includes:

When the first application processor 10 acquires the upgrade package, the first application processor 10 transmits an upgrade instruction to the second application processor 20. The first application processor 10 and the second application processor 20 perform data transmission through a universal serial bus. The first application processor 10 may obtain the upgrade package by means of FOTA upgrade, or copy the upgrade package to a specified directory of the mobile terminal, such as an SD card directory or a data directory, by the user.

the second application processor 20 receives the upgrade instruction sent by the first application processor 10, and shares the storage interval to the first application processor 10 according to the upgrade instruction. When the first application processor 10 detects the storage interval sent by the second application processor 20, the upgrade package is shared to the second application processor 20 through the storage interval. That is, the second application processor 20 shares the built-in SD card directory to the first application processor 10 through USB, and when the first application processor 10 detects the SD card of the second application processor 20, copies the upgrade package into the SD card of the second application processor 20.

The second application processor 20 is further configured to, when the upgrade package is detected, perform system upgrade according to the upgrade package.

The second application processor 20 receives the request command sent by the first application processor 10, and sends the version number of the system upgrade where the second application processor 20 is located to the first application processor 10 according to the request command.

The first application processor 10 is further configured to receive a version number of the system where the second application processor 20 is located after the system is upgraded, and if the version number of the system where the second application processor 20 is located after the system is upgraded is the same as the version number of the upgrade package, it is determined that the system where the second application processor 20 is located is upgraded successfully.

When the first application processor 10 receives the version number of the system in which the second application processor 20 is located after the system upgrade, the first application processor 10 determines whether the version number of the system in which the second application processor 20 is located after the system upgrade is the same as the version number of the upgrade package. If the version number of the system in which the second application processor 20 is located after the system upgrade is the same as the version number of the upgrade package, the first application processor 10 determines that the system in which the second application processor 20 is located is upgraded successfully. If the version number of the system in which the second application processor 20 is located after the system upgrade is different from the version number of the upgrade package, the first application processor 10 determines that the system upgrade in which the second application processor 20 is located fails. Further, when the system where the second application processor 20 is located fails to be upgraded, the second application processor 20 obtains the upgrade package from the first application processor 10 again, or sends the reason of the upgrade failure to the server, so that the manufacturer of the upgrade package can improve the upgrade package according to the reason of the upgrade failure.

The first application processor 10 and the second application processor 20 may download the upgrade package through their respective networks, and perform system upgrade according to their respective downloaded upgrade packages.

Referring to fig. 3, fig. 3 is a flowchart illustrating a data sharing method of a dual chip system according to a first embodiment of the present invention. By the method, the data packet sharing between the chip systems can be realized, and the data sharing method of the dual-chip system provided by the invention is described below by taking the data packet as an upgrade packet as an example.

In this embodiment, the data sharing method of the dual chip system includes:

step S10, when the first application processor obtains the upgrade package, sending an upgrade instruction to the second application processor;

specifically, the dual-chip system provides a first processing chip, a second processing chip, a Wi-Fi module and a storage device, wherein the first processing chip is respectively in communication connection with the second processing chip, the Wi-Fi module and the storage device: the first processing chip comprises a first application processor, and the second processing chip comprises a second application processor which is in communication connection with the first processing chip.

When a system where a second application processor of the mobile terminal is located needs to be upgraded, a control instruction of a user is received, the first application processor obtains an upgrade package needed by the system of the second application processor through the Wi-Fi module and/or the storage device according to the control instruction, and sends the upgrade instruction to the second application processor. The first application processor is a main control end and is used for controlling a system where the first application processor is located and a system where the second application processor is located. The first application processor and the second application processor perform data transmission through a universal serial bus. Mobile terminals include, but are not limited to, smart phones and ipads. The first application processor may obtain The upgrade package in a FOTA (Firmware Over-The-Air) upgrade manner, or copy The upgrade package to a specified directory of The mobile terminal, such as an SD (Secure Digital Memory Card) Card directory or a data directory by The user. FOTA is an over-the-air software of a mobile terminal, and refers to a device with a networking function by a cloud upgrading technology: for example, a mobile phone, a tablet computer, a portable media player, a mobile internet device and the like provide firmware upgrading services, a user obtains an intelligent terminal system upgrading package in an on-demand and easily-extensible manner by using a network, and cloud upgrading is performed through FOTA to complete system repair and optimization.

Further, when the first application processor acquires the upgrade package, the version number of the upgrade package is acquired from the upgrade package. The first application processor sends an acquisition instruction to the second application processor, when the second application processor receives the acquisition instruction sent by the first application processor, the second application processor acquires the version number of the system where the second application processor is located before upgrading according to the acquisition instruction, and sends the version number of the system where the second application processor is located before upgrading to the first application processor. When the first application processor receives the version number which is not upgraded and sent by the second application processor, the version number which is not upgraded and the version number of the upgrade package of the system where the second application processor is located are compared, and when the first application processor judges that the version number which is not upgraded and located in the system where the second application processor is located is lower than the version number of the upgrade package, the system where the second application processor is located is judged to need to be upgraded. And when the first application processor judges that the version number of the system where the second application processor is located before upgrading is the same as the version number of the upgrading packet, judging that the system where the second application processor is located does not need to be upgraded.

Step S20, the second application processor receives the upgrade instruction and shares the storage interval to the first application processor according to the upgrade instruction;

step S30, when the first application processor detects the storage interval, the upgrade package is shared to the second application processor through the storage interval;

and the second application processor receives the upgrading instruction sent by the first application processor and shares the storage interval to the first application processor according to the upgrading instruction.

And the second application processor enters a recovery mode, upgrades according to the upgrade package stored in the SD card, and sends upgrade information to the first application processor so as to inform the first application processor that the second application processor starts upgrading according to the upgrade package. Recovery mode refers to a mode in which data or systems inside the android can be modified. In the Recovery mode, a new android system can be refreshed, or an existing system can be backed up or upgraded, and factory settings can be restored at the same time.

Further, when the second application processor is upgraded successfully, the first application processor deletes the upgrade package. If the system where the first application processor is located needs to be upgraded, the first application processor downloads the upgrade package required by the upgrade again, and the system is upgraded according to the upgrade package downloaded again. Furthermore, after the system upgrade of the first application processor is successful, the first application processor obtains the version number of the first application processor after the system upgrade and compares the version number of the first application processor after the system upgrade with the version number of the upgrade package downloaded again. If the version number of the system where the first application processor is located after the system is upgraded is the same as the version number of the upgrade package, indicating that the system where the first application processor is located is upgraded successfully; and if the version number of the system where the first application processor is located after the system is upgraded is different from the version number of the upgrade package, indicating that the system where the first application processor is located fails to be upgraded. When the system where the first application processor is located is upgraded successfully, the first application processor deletes the upgrade package downloaded again so as to save the storage space; and when the system where the first application processor is located fails to be upgraded, the first application processor acquires the upgrade package again to carry out system upgrade, and if the system where the first application processor is located fails to be upgraded again, the first application processor sends the reason of the system upgrade failure to the server so that a manufacturer of the upgrade package can improve the upgrade package according to the reason of the upgrade failure.

In other embodiments, the upgrade package acquired by the first application processor includes upgrade package data required by the system in which the first application processor is located and upgrade package data required by the system in which the second application processor is located. When the first application processor acquires the data packet, the data packet is analyzed, the upgrading packet data required by the system where the second application processor is located is copied into the shared storage space through the USB, when the second application processor detects the upgrading packet data in the storage area of the second application processor, the second application processor enters a recovery mode, upgrading is carried out according to the upgrading packet stored in the SD card, and upgrading information is sent to the first application processor to inform the first application processor that the second application processor starts upgrading according to the upgrading packet.

In other embodiments, the upgrade package acquired by the first application processor includes upgrade package data required by the system in which the first application processor is located and upgrade package data required by the system in which the second application processor is located. After the first application processor acquires the data packet, the upgrade packet is copied into the shared storage space through the USB, after the second application processor detects the upgrade packet data in the storage area of the second application processor, the upgrade packet data is analyzed, the second application processor enters a recovery mode, upgrade is performed according to the upgrade packet data which is stored in the SD card and is required by a system where the second application processor is located, and upgrade information is sent to the first application processor to inform the first application processor that the second application processor starts to upgrade according to the upgrade packet.

It should be noted that the data package may also be an installation package. When the data package is an installation package, the sharing of the installation package between the first application processor and the second application processor is similar to the sharing of the upgrade package, and details are not repeated here.
