## Background
This application claims priority to International Application No. PCT/CN2011/083640 filed Dec. 7, 2011 and to Chinese Patent Appln. No. CN201010591149.3 filed Dec. 15, 2010; the entire contents of each are incorporated herein by reference.
The present application relates to the field of communication technology, and more particularly, to a system-state control method and a portable terminal.
BACKGROUND
As for a portable terminal of hybrid system architecture, a hybrid system refers to 2 (including 2) or more systems that are combined together. For example, on the basis of an existing system, at least another system (including another PC system or an embedded system, etc.) is embedded, so that the different systems can work integrated with each other, share information and devices, and play their respective advantages. An existing common portable terminal of hybrid system architecture, usually integrates a master system or a first system (e.g., Win7) with a slave system or a second system (e.g., Android), in which the master system and the slave system can share keyboards, network cards, displays, storage devices, Audios, etc. with each other, and can implement connection and disconnection in organization and interface. When disconnected, the two systems can both work independently; when integrated, the two systems can work cooperatively. With a notebook computer as an example, usually, a display screen when disconnected is integrated on a slave system, whereas keyboard, audio, storage system, etc. when disconnected are integrated on a master system; the master system and the slave system can be combined together to work cooperatively, and also can work independently; the display screen when working independently is used by the slave system, and the display screen when working in combination can be used by either the master system or the slave system.
The inventors found in a study on an existing portable terminal of hybrid structure that, when a master system and a slave system are combined together or disconnected, if the system states of them are inconsistent, for example, when a slave system needs to be combined and work cooperatively with a master system, and if the slave system is in a work state whereas the master system is in a sleep state, then after connecting by inserting the slave system into the master system, it is still necessary for the user to manually wake up the master system, so that the cooperative work of the two systems can be implemented. As can be known from that, for an existing master system, when it is combined with or disconnected from a slave system, the two system states hardly can implement automatic switching based on a user's needs.

DETAILED DESCRIPTION
Among the following several embodiments of the present application, some embodiments provide a system-state control method, and some embodiments provide a portable terminal.
To make the technical solutions in the embodiments of the present application better understood by the skilled in the art, and to make the above object, features and advantages of the embodiments of the present application more apparent and understandable, below, the technical solutions in the embodiments of the present application will be described in more detail in connection with the accompanying drawings.
The embodiment of the system-state control method provided by the present application, is applied in a portable terminal comprising a first system and a second system, in which the first system has a first interface and the second system has a second interface, and in which the first system and the second system implement connection or disconnection via the first interface and the second interface. The first system of the portable terminal may specifically be a master system (also may be referred to as Base) running an X86 system, and the second system may specifically be a slave system (also may be referred to as Slate) running an ARM system; the first interface may specifically be a USB interface, also may be a UART interface or a special interface used for connection or disconnection between the two systems, meanwhile, the second interface may be a USB interface, also may be a UART interface or a special interface used for connection or disconnection between the two systems. Here it is not limited in this regard, as long as the first interface of the first system and the second interface of the second system can implement connection and disconnection of the two systems, as well as can communicate mutually on system-state information. The above-described Base and Slate are tow relatively independent systems, which can respectively work independently or can be connected to work together, and when working as connected, they can also share some of the hardware devices, for example a display device, which means, a display device, usually integrated with a slave system, can only be used by the slave system when a master system and a slave system are in disconnection (also referred to as Detach or Pull-Out), whereas can be used by the master system and also by the slave system when the master system and the slave system are in connection (also referred to as Attach or Push). In addition, the first system is a system which is constituted by a first hardware system and a first operating system based on the first hardware system, meanwhile, the second system is a system which is constituted by a second hardware system and a second operating system based on the second hardware system. The first system and the second system also may be systems which have the same operating system, for example, the first system and the second system both are systems running an X86 system, or the first system and the second system both are systems running an ARM system.
In the embodiment of the present application, no matter the master system or the slave system, their system states comprise a work state (or S0) and a non-work state, respectively; further, the non-work state can be subdivided into a sleep state (or S3) and an off state (or S4/S5). In the prior art, when a master system and a slave system enter a connected state from a disconnected state, or enter a disconnected state from a connected state, it is usually necessary for a user to trigger a change of the system state by controlling the hardware on each of the systems. In the prior art, no matter the master system or the slave system, both can not adjust the system state of its own system or adjust the system state of the other system, based on a connection relationship (i.e., connection or disconnection) between the two systems.
Referring to FIG. 1, it is a flowchart of a first embodiment of a system-state control method provided by the present application:
Step 101: when the first system and the second system enter a connected state from a disconnected state, the first system and the second system interact on their respective system-state information.
Step 102: the first system and the second system, based on the system-state information, perform control to the system state according to a predetermined strategy.
The predetermined strategy may comprise: when the first system and the second system are in a same system state as they are in a disconnected state, then after entering a connected state, their respective system states are kept unchanged; said being in a same system state includes being simultaneously in a work state, or being simultaneously in a non-work state; when one system from the first system and the second system is in a work state while the other system is in a non-work state as they are in a disconnected state, then after entering a connected state, the system in a non-work state enters a work state automatically.
In the system-state control, there may comprise two modes as follows:
a first mode: the first system, based on its own system-state information and the system-state information of the second system, control its own system state according to a predetermined strategy; and the second system, based on its own system-state information and the system-state information of the first system, control its own system state according to a predetermined strategy.
a second mode: the first system, based on its own system-state information and the system-state information of the second system, control its own system state and control the system state of the second system, according to a predetermined strategy; or, the second system, based on its own system-state information and the system-state information of the first system, control its own system state and control the system state of the first system, according to a predetermined strategy; further, the first system also may only, based on the obtained system-state information of the second system, control the system state of the second system according to a predetermined strategy, or, the second system also may only, based on the obtained system-state information of the first system, control the system state of the first system according to a predetermined strategy.
Below, in connection with the first embodiment described above, a detailed description will given on a few examples which perform system-state control by applying the embodiment of the present application, in which the first system is a master system and the second system is a slave system, with assuming that the first system and the second system enter a connected state from a disconnected state:
1. when in a disconnected state, the master system is in state S0 and the slave system is in state S0, then after entering a connected state, the master system and the slave system both remain state S0;
2. when in a disconnected state, the master system is in state S0 and the slave system is in state S3, then after entering a connected state, the master system still remains state S0 and at the same time automatically wakes up the slave system, so that the slave system enters state S0 from state S3; according to the system-state control mode in the above-described embodiment, after the two systems are connected, the master system, based on the system state S3 of the slave system and based on its own system state S0, controls its own system state unchanged and at the same time automatically wakes up the slave system, so that the system state of the slave system occurs change and enters state S0 from state S3; of course, according to another implementation mode, after the two systems are connected, the master system, based on the system state S3 of the slave system and based on its own system state S0, controls its own system state unchanged, meanwhile, the slave system, based on the system state of the master system and its own system state, controls its own system state to change and enters state S0 from state S3. Of course, according to yet another implementation mode, the slave system, based on the system state of the master system and its own system state, controls its own system state to change and enters state S0 from state S3, and at the same time controls the master system to remain its own system state as unchanged.
3. when in a disconnected state, the master system is in state S0 and the slave system is in state S4/S5, then after entering a connected state, the master system still remains state S0 and at the same time automatically turns on the slave system, so that the slave system enters state S0 from state S4/S5; the specific implementation modes are the same as the above-described three modes, which are no more described here.
4. when in a disconnected state, the master system is in state S3 and the slave system is in state S0, then after entering a connected state, the slave system still remains state S0 and at the same time automatically wakes up the master system, so that the master system enters state S0 from state S3; the specific implementation modes are the same as the above-described three modes, which are no more described here.
5. when in a disconnected state, the master system is in state S3 and the slave system is in state S3, then after entering a connected state, the master system and the slave system both remain state S3; the specific implementation modes are the same as the above-described three modes, which are no more described here.
6. when in a disconnected state, the master system is in state S3 and the slave system is in state S4/S5, then after entering a connected state, the master system still remains state S3, and the slave system still remains state S4/S5; the specific implementation modes are the same as the above-described three modes, which are no more described here.
7. when in a disconnected state, the master system is in state S4/S5 and the slave system is in state S0, then after entering a connected state, the slave system still remains state S0 and at the same time automatically turns on the master system, so that the master system enters state S0 from state S4/S5; the specific implementation modes are the same as the above-described three modes, which are no more described here.
8. when in a disconnected state, the master system is in state S4/S5 and the slave system is in state S3, then after entering a connected state, the master system still remains state S4/S5, and the slave system still remains state S3; the specific implementation modes are the same as the above-described three modes, which are no more described here.
9. when in a disconnected state, the master system is in state S4/S5 and the slave system is in state S4/S5, then after entering a connected state, the master system and the slave system both remain state S4/S5. The specific implementation modes are the same as the above-described three modes, which are no more described here.
It should be noted that, the above are merely a few examples, which are listed for explaining the systems of the portable terminal can automatically control the state changes; in actual applications, strategies can be adjusted depending on a user's needs, and the embodiment of the present application is not limited in this regard. For example, when in a disconnected state, the master system is in state S0 and the slave system is in state S3, then after entering a connected state, the states of both the master system and the slave system are not changed.
Referring to FIG. 2, it is a flowchart of a second embodiment of the system-state control method provided by the present application:
Step 201: when the first system and the second system are in a connected state with each other, the first system and the second system interact on their respective system-state information according to a preset condition.
When the first system and the second system are in a connected state with each other, in order to ensure that, after entering a disconnected state, system-state control can be performed based on the original system-state information, the first system and the second system thus need to interact on their respective system-state information. The interaction on system-state information can be performed according to a preset condition, and this comprises: the first system and the second system interact on their respective system-state information at predefined time intervals; or, the first system and the second system interact on their respective system-state information in real time; or, when any one system from the first system and the second system occurs a change in its system state, a notification message containing the changed system-state information is sent to the other system.
Step 202: when the first system and the second system enter a disconnected state from a connected state, the first system and the second system, based on the system-state information, perform control to the system state according to a predetermined strategy.
The predetermined strategy may comprise: when the first system and the second system are both in a work state, then after entering a disconnected state, the first system enters a non-work state, and the second system enters a work state; when the first system is in a non-work state and the second system is in a work state, then after entering a disconnected state, the first system will enter a work state, and the second system remains its own system state. Said system state comprises a work state and a non-work state.
In the system-state control, there may comprise two modes as follows:
a first mode: the first system, based on its own system-state information and the system-state information of the second system, control its own system state according to a predetermined strategy; and the second system, based on its own system-state information and the system-state information of the first system, control its own system state according to a predetermined strategy.
a second mode: the first system, based on its own system-state information, control its own system state according to a predetermined strategy; and the second system, based on its own system-state information, control its own system state according to a predetermined strategy.
Below, in connection with the second embodiment described above, a detailed description will given on a few examples which perform system-state control by applying the embodiment of the present application, in which the first system is a master system and the second system is a slave system, with assuming that the first system and the second system enter a disconnected state from a connected state:
1. when in a connected state, the master system is in state S0 and the slave system is in state S0, then after entering a disconnected state, the master system enters state S3, and the slave system remains state S0;
2. when in a connected state, the master system is in state S0 and the slave system is in state S3, then after entering a disconnected state, the master system enters state S3 and at the same time automatically wakes up the slave system, so that the slave system enters state S0 from state S3;
3. when in a connected state, the master system is in state S0 and the slave system is in state S4/S5, then after entering a disconnected state, the master system enters state S3 and at the same time automatically turns on the slave system, so that the slave system enters state S0 from state S4/S5;
4. when in a connected state, the master system is in state S3 and the slave system is in state S0, then after entering a disconnected state, the slave system still remains state S0, and the master system still remains state S3;
5. when in a connected state, the master system is in state S3 and the slave system is in state S3, then after entering a disconnected state, the master system and the slave system both remain state S3;
6. when in a connected state, the master system is in state S3 and the slave system is in state S4/S5, then after entering a disconnected state, the master system still remains state S3, and the slave system still remains state S4/S5;
7. when in a connected state, the master system is in state S4/S5 and the slave system is in state S0, then after entering a disconnected state, the slave system still remains state S0, and the master system remains state S4/S5;
8. when in a connected state, the master system is in state S4/S5 and the slave system is in state S3, then after entering a disconnected state, the master system still remains state S4/S5, and the slave system still remains state S3;
9. when in a connected state, the master system is in state S4/S5 and the slave system is in state S4/S5, then after entering a disconnected state, the master system and the slave system both remain state S4/S5.
It should be noted that, the above are merely a few examples, which are listed for explaining the systems of the portable terminal can automatically control the state changes; in actual applications, strategies can be adjusted depending on a user's needs, and the embodiment of the present application is not limited in this regard. For example, when in a connected state, the master system is in state S0 and the slave system is in state S3, then after entering a disconnected state, the states of both the master system and the slave system are not changed.
As can be seen from the above embodiments, compared to the case of the prior art where a user needs to control a system-state change via a switch Power Button of the hardware system when a connected state between a master system and a slave system is changed, the present application actually adds a new triggering mechanism for a state change, e.g., the slave system is inserted into the master system or pulled out from the master system, and the triggering performs automatic system-state control; the specific controlling process may be implemented based on the system-state information of the two systems in accordance with the description of the aforementioned embodiments.
Referring to FIG. 3, it is a schematic structural diagram of a portable terminal which performs system control by applying the system-state control method provided by the present application:
Base is used as a master system which comprises an embedded controller EC, and Slate is used as a slave system which comprises a micro control unit MCU; on the EC and the MCU, there are provided with a physical interface respectively, and corresponding detection and communication channels are added to the physical interfaces. As shown in FIG. 3, B_DET is used to transmit first signals of Base from the EC to the MCU, and when the master system and the slave system are connected, B_DET corresponds to the detection channel of the MCU, thus Slate can detect whether Base exists based on the first signals; S_DET is used to transmit second signals of Slate from the MCU to the EC, and when the master system and the slave system are connected, S_DET corresponds to the detection channel of the EC, thus Base can detect whether Slate exists based on the second signals; S_BUS is a serial communication bus, such as I2C (Inter-Integrated Circuit), SPI (Serial Peripheral Interface), UART (Universal Asynchronous Receiver/Transmitter), etc., in which there contains necessary interrupt-lines for transmitting system states of Base and Slate between the EC and the MCU. When the master system and the slave system are connected, S_BUS constitutes a communication channel between the master system and the slave system. Furthermore, B_DET, detection channel and S_BUS can be used as at least part of the first interface of the master system. S_DET, detection channel and S_BUS can be used as at least part of the second interface of the slave system.
In connection with FIG. 3, it is assumed that when Base and Slate are in a disconnected state, the system state of Base is S3, and the system state of Slate is S0. After Slate is inserted into Base, the EC of Base detects a change in S_DET and thereby determines the event that Slate is inserted into Base. At this point, the EC of Base communicates via S_BUS with the MCU of Slate, and obtains that the system state of Slate is S0 while the system state of Base is S3; thus, based on the aforementioned predetermined control strategy, Base is automatically woken up and enters S0 state, whereas Slate remains state S0.
A typical application scenario in connection with the above embodiment is as follows: when Base and Slate are disconnected, Base is in state S3 and Slate is in state S0, that is, a user has been using Slate alone all the time, then when the user wants to connect Slate onto Base for charging or wants to copy a file, Slate needs to be inserted into Base. In the prior art, in this case, the user needs to again manually press the hardware switch of Base, or to turn on the hardware switch LID to wake up Base; in contrast, by using the embodiment of the present application, it is possible to automatically turn on Base, based on a preset corresponding relationship between the system-state information and the state-control information, thereby eliminating a user's manual operation and bringing consistency of accustomation.
In addition, there is another application in the prior art: when the first system and the second system are a Notebook (Tablet PC) and a Dock (a system for docking and undocking the Notebook), respectively, then, it is possible to set corresponding actions for a system-state change through a specific program when the two systems are in docking and undocking, and the docking and undocking actions are similar to the inserting and ejection actions of Base and Slate in the aforementioned application. However, since docking/undocking of Dock is essentially an action similar to interaction between a device and a system, in which the device itself does not have such a property as a system state, so the docking/undocking event is still a property similar to a hardware switch.
