Be in major state below in conjunction with the first operating system acquiescence after terminal device 1 is started shooting, and the situation that the second operating system enters holding state immediately after having loaded is described.
Here, during the first operating system is in major state, the first performance element 11 can based on first operating system control inputs/output unit 13.Now, the second operating system is in holding state, and I/O unit 13 does not control by the second operating system.In addition, during the first operating system is in major state, first performance element 11 can run this first operating system (intelligent system) and perform various program based on this first operating system, and the second performance element 12 can be realized by the communication module of such as baseband processor and so on, therefore the second performance element 12 can carry out the process relevant to communication protocol.In this case, the first performance element 11 can select the second performance element 12 to perform the communication with external unit.Certainly, when terminal device 1 has other communication module of such as Wifi, bluetooth, infrared ray and so on, the first performance element 11 can select the particular element in the second performance element 12 and other communication module above-mentioned to perform the communication with external unit according to concrete environment for use.
According to embodiments of the invention, during the first operating system is in major state, the first performance element 11 can monitor whether meet the switching condition preset.If the first performance element 11 judges to meet default switching condition (in order to distinguish, hereinafter referred to the first switching condition), then the first performance element 11 produces and is used to indicate the first switching command being switched to the second operating system, and this first switching command is sent to the second performance element 12.Then, the first performance element 11 and the second performance element 12 perform switching based on this first switching command, make the second operating system be in major state.
Particularly, during the first operating system is in major state, if the first operating system receives the process request relevant to the first data, then the first performance element 11 can determine satisfied first switching condition.Here, the switching entrance (e.g., application icon) relevant to the process of these the first data can be provided in the first operating system to make user can produce the process request relevant to the first data by selecting/clicking this switching entrance.Such as, when the user of terminal device 1 wishes to browse the first data of such as associated person information or short message and so on, this user can produce the process request relevant to the first data by selecting/clicking the associated inlet (e.g., contact person or note icon) that the first operating system provides.In addition, the user of terminal device 1 wish to use such as Net silver, online shopping mall or Alipay and so on relate to the application paying or transfer accounts time, this user can produce the process request relevant to the first data by selecting/clicking the associated inlet (e.g., Alipay icon) that the first operating system provides.Here, when the first performance element 11 receives the process request relevant to the first data, the first performance element 11 can be determined satisfied first switching condition and produce the first switching command.In addition, multiple process request relevant to the first data can be preset in the first operating system, and when one of process request that the process request relevant to the first data that the first operating system receives is relevant with multiple and the first data preset is mated, the first performance element 11 can be determined satisfied first switching condition and produce the first switching command.Here, the first switching command can comprise and such as controls the first operating system and enter holding state and wake the control information such as the second operating system and the process request relevant to the first data being in holding state up.
Then, during the first performance element 11 and the second performance element 12 make the second operating system be in major state based on the first switching command execution switching, first performance element 11 preserves the breakpoint information (recovery for first operating system) relevant to the current state of the first operating system based on this first switching command, and makes the first operating system enter holding state.Now, the first operating system surrenders the control authority of I/O unit 13.After receiving the first switching command, the second performance element 12 wakes the second operating system up based on this first switching command, and the second performance element 12 is based on second operating system control inputs/output unit 13.Now, terminal device 1 is in function machine pattern (from pattern).
Here, during the second operating system is in major state, the second performance element 12 runs this second operating system and carries out the process relevant to communication protocol, and terminal device 1 can be made thus to communicate with its external unit.In this case, the second performance element 12 can play application processor and communication unit simultaneously.In addition, during the second operating system is in major state, the second performance element 12 controls (adapter) I/O unit 13 based on the second operating system, and now the first performance element 11 is in holding state.In this case, terminal device 1 is in function machine pattern.When the second operating system is switched to major state according to the first switching command, in the application program that the second performance element 12 can also be installed from the second operating system according to the process request relevant to the first data comprised in the first switching command, select corresponding process first data that should be used for this process request.Such as, the user described before select/click the first operating system provides with the first data (as, contact person or note) corresponding associated inlet when, when the second operating system is switched to major state according to the first switching command, the second performance element 12 processes this first data according to the application (contact person or note are applied) corresponding with the process request of the first data comprised in this first switching command.In addition, the user described before select/click to provide in the first operating system with the first data (as, pay application) corresponding associated inlet when, when the second operating system is switched to major state according to the first switching command, processing unit 11 processes this first data according to the application corresponding with the process request of the first data comprised in this first switching command (e.g., pay apply).In this case, the user of terminal device 1 can not discover the switching operating system substantially, thus has ensured the experience of user.
In addition, according to another embodiment of the invention, if the process request relevant to the first data comprise the first data (as, user fill in username and password and clicks and submits to or send button on the browser or payment application of the first operating system), then except determining satisfied first switching condition and producing except the first switching command, first performance element 11 is also before preservation breakpoint information, the second fill order 12 yuan is sent to maybe these first data to be stored on the predeterminated position of storage unit 10 first data (e.g., username and password).In this case, when the second operating system is switched to major state in the way described before, second performance element 12 can obtain this first data, and continues to process this first data according to application corresponding to the process request selecting relevant to the first data in the first switching command (in this example for browser or pay is applied).
By above-mentioned configuration, owing to being completed by the second operating system (function machine operating system) the process of important user data or system data, even if the various rogue program that therefore had hacker for the application development installed in the first operating system or the first operating system, because the first operating system of being infected or application program wherein do not have the access right to the first data (important user data or system data), therefore it can not obtain or distort the first data, drastically increases the security performance of terminal device 1 thus.
In addition, according to another embodiment of the invention, wherein during the second operating system is in major state, a part of hardware module of the terminal device 1 enabled when the first operating system is in major state is disabled.Here, because the second operating system is for function machine system and its function that can provide less (e.g., basic call, note, network function etc.), functions that some add therefore are not needed.Therefore, a part of hardware module of the terminal device 1 enabled under intelligent system can be forbidden.Such as, as shown in Figure 2 A, terminal device 1 can also comprise the hardware module of such as WIFI14, GPS15, gravity sensor 16 and gyroscope 17 and so on, and above-mentioned hardware module is in initiate mode in the first operating system, but, as shown in Figure 2 B, above-mentioned hardware module (WIFI14, GPS15, gravity sensor 16 and gyroscope 17 etc.) can be in disabled status under the second operating system.In this case, not only can improve the security performance of terminal device 1, effectively can also reduce the power consumption of terminal device 1.
In addition, according to another embodiment of the invention, wherein terminal device 1 comprises first communication module and second communication module further.Here, first communication module can be Wifi module, and second communication module can be the second performance element 12 realized by 2G/GPRS/3G baseband processor, and the data rate of second communication module is lower than first communication module.According to the present embodiment, during the first operating system is in major state, this first communication module and second communication module are all activated, and during the second operating system is in major state, only second communication module is activated, and forbid first communication module.In this case, be easy to be cracked due to first communication module (Wifi module) and easily make important user data or system data lose or be tampered, therefore during the second operating system major state, only enabling the security performance that second communication module can improve terminal device 1 further.In addition, according to another embodiment of the invention, during the first operating system is in major state, this first communication module and second communication module are all activated, and during the second operating system is in major state, first communication module and second communication module also can all be activated.In this case, during the second operating system is in major state, the priority of acquiescence second communication module is higher than this first communication module (Wifi module), namely when the signal about two communication modules all exists, use second communication module to communicate, so also can prevent from being easy to be cracked the generation of the situation causing important user data or system data to be lost or to be tampered due to first communication module.
The operation switching back the first operating system from the second operating system will be described below.
During the second operating system is in major state, the second performance element 12 monitors whether meet the switching condition (hereinafter referred to the second switching condition) preset.If the second performance element 12 judges to meet this second switching condition, then the second performance element 12 produces and is used to indicate the second switching command being switched to the first operating system, and the second switching command is sent to the first performance element 11.Then, the first performance element 11 and the second performance element 12 perform switching based on the second switching command, make the first operating system be in major state.
