Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the accompanying drawings.
For simplicity and clarity of description, the invention will be described below by describing several representative embodiments. Numerous details of the embodiments are set forth to provide an understanding of the principles of the invention. It will be apparent, however, that the invention may be practiced without these specific details. Some embodiments are not described in detail, but rather are merely provided as frameworks, in order to avoid unnecessarily obscuring aspects of the invention. Hereinafter, "comprising" means "including but not limited to", "according to … …" means "at least according to … …, but not limited to … … only". In view of the language convention of chinese, the following description, when it does not specifically state the number of a component, means that the component may be one or more, or may be understood as at least one.
The applicant found that: in the current dual-system terminal, a user cannot simultaneously operate two operating systems. For example, for a dual-system terminal including a work area operating system and a living area operating system, a user cannot operate the two operating systems at the same time.
The applicant has analysed the above problems and found possible causes to be: currently, a dual-system terminal mostly has only one input resource and one display resource (for example, the input resource and the display resource are integrated into a display screen with a touch function), and only one operating system can independently operate the only input resource and the only display resource of the dual-system terminal at a certain time. Not only this, possible reasons include: at present, some hardware resources can not support two operating systems to operate simultaneously, such as hardware resources of Bluetooth, wifi, SD card and sound input.
The applicant found that: for the hardware resources that cannot be simultaneously operated by two operating systems at present, part of the hardware resources can realize simultaneous shared access of the two operating systems by driving a virtual and bridging mechanism, and the hardware resources that cannot be simultaneously shared access need to be assigned to a specific operating system. Applicants have further discovered that each operating system requires the exclusive ownership of hardware resources (e.g., touch screens) for display and input, and thus embodiments of the present invention employ dual-screen mobile terminals to support simultaneous dual-system operation, where each screen needs to be assigned to a particular operating system.
Fig. 1 is a flowchart of a method for simultaneously operating dual systems according to an embodiment of the present invention. The method is suitable for a mobile terminal comprising a first screen and a second screen, wherein double systems, namely a first operating system and a second operating system, are installed in the mobile terminal. For example, the mobile terminal simultaneously carries a secure operating system and a living operating system, the secure operating system is used for work and office, and the living operating system is used for living communication.
As shown in fig. 1, the method includes:
step 101: the first screen is assigned to a first operating system and the second screen is assigned to a second operating system.
Here, the first screen is exclusively allocated to the first operating system, and displays user-triggered information in the first operating system or information provided to the user based on a control instruction of the first operating system. After the first screen is exclusively allocated to the first operating system, the second operating system cannot manipulate the first screen.
And exclusively allocating a second screen to the second operating system, the second screen displaying user-triggered information in the second operating system or information provided to the user based on a control instruction of the second operating system. After the second screen is exclusively allocated to the second operating system, the first operating system does not manipulate the second screen.
In the case of simultaneously operating the dual systems, when a single system needs to perform operations related to display and input (e.g., outputting a presentation interface and receiving user input), hardware resources related to display and input (e.g., a touch screen) need to be monopolized, and thus a general dual system terminal in the prior art cannot support the dual systems to simultaneously perform operations related to display and input. The embodiment of the present invention employs a dual-screen mobile terminal to support simultaneous operation and operation of dual systems, in which each screen is assigned to a specific operating system of the dual systems, thereby supporting the dual systems to simultaneously perform operations related to display and input.
Step 102: aiming at shared hardware resources simultaneously accessed by a first operating system and a second operating system, virtualizing a first driving node accessible to the first operating system and a second driving node accessible to the second operating system in a kernel driving layer, bridging the first driving node and the second driving node, and associating the bridging point to hardware drivers of the shared hardware resources simultaneously accessed by the first operating system and the second operating system.
In one embodiment, the shared hardware resources that the first operating system and the second operating system access simultaneously include hardware resources related to network access, such as a WIFI hardware module, a bluetooth hardware module, an infrared hardware module, and the like.
FIG. 2 is a diagram illustrating a driving node bridge according to an embodiment of the present invention.
As shown in fig. 2, for a shared hardware resource simultaneously accessed by a first operating system and a second operating system, a first driver node accessible to the first operating system and a second driver node accessible to the second operating system are virtualized in a kernel driver layer of the mobile terminal. The first driving node is bridged with the second driving node, and the bridging point is associated with the hardware driver of the shared hardware resource accessed by the first operating system and the second operating system at the same time.
For example, assuming that the hardware driver is a driver of the WIFI hardware module, a first WIFI driver node accessible to a first operating system and a second WIFI driver node accessible to a second operating system are virtualized in a kernel driver layer of the mobile terminal. The first WIFI driving node is in bridge connection with the second WIFI driving node, and the bridge connection point is associated with a driving program of the WIFI hardware module.
When a user of a first operating system slides on a display screen distributed by the first operating system to send a first instruction for transmitting a wireless broadband data packet, the first operating system sends the first instruction to a first WIFI driving node in a kernel driving layer, the first WIFI driving node sends the first instruction to a bridging point, and the bridging point caches the first instruction; when a user of the second operating system sends a second instruction for transmitting the wireless broadband data packet on a display screen allocated by the second operating system, the second operating system sends the second instruction to a second WIFI driving node in the kernel driving layer, the second WIFI driving node sends the second instruction to the bridging point, and the bridging point caches the second instruction. And, at the bridge point, the bridge point sequentially sends the cached instructions to the driver of the WIFI hardware module based on a predetermined timing (e.g., the instruction that arrives at the bridge point first is processed, or the instruction is processed based on the priority order of the first operating system and the first operating system), so that the driver drives the WIFI hardware module to sequentially execute the cached instructions. As can be seen, the first operating system and the second operating system may share the WIFI hardware module, and respectively implement the function of transmitting the wireless broadband data packet.
For another example, assuming that the hardware driver is a driver of a bluetooth hardware module, a first bluetooth driver node accessible to a first operating system and a second bluetooth driver node accessible to a second operating system are virtualized in a kernel driver layer of the mobile terminal. The first Bluetooth driving node is in bridge connection with the second Bluetooth driving node, and the bridge connection point is associated with a driving program of the Bluetooth hardware module.
When a user of a first operating system slides on a display screen distributed by the first operating system to send a first instruction for receiving a Bluetooth data packet, the first operating system sends the first instruction to a first Bluetooth driving node, the first Bluetooth driving node sends the first instruction to a bridging point, and the bridging point caches the first instruction; when a user of the second operating system sends a second instruction for receiving the Bluetooth data packet on a display screen distributed by the second operating system, the second operating system sends the second instruction to the second Bluetooth driving node, the second Bluetooth driving node sends the second instruction to the bridging point, and the bridging point caches the second instruction. At the bridge point, the bridge point sequentially sends the cached instructions to the driver of the bluetooth hardware module based on a predetermined timing (e.g., the instructions that arrive at the bridge point first are processed, or the instructions are processed based on the first operating system and the priority order of the first operating system), so that the driver drives the bluetooth hardware module to sequentially execute the cached instructions. Therefore, the first operating system and the second operating system can share the bluetooth hardware module to realize the function of receiving the bluetooth data packet respectively.
The above description is made by taking WIFI hardware and bluetooth hardware as examples, and those skilled in the art will appreciate that this description is only exemplary and is not intended to limit the scope of the embodiments of the present invention.
Step 103: and allocating the shared hardware resources which are not accessed by the first operating system and the second operating system at the same time to the first operating system or the second operating system based on a user instruction.
In one embodiment, the shared hardware resources that are not accessed simultaneously by the first operating system and the second operating system include a camera, audio codec hardware resources, and video codec hardware resources.
Here, the shared hardware resource that is not accessed by the first operating system and the second operating system at the same time is allocated to the first operating system or the second operating system based on a user instruction. For example, one of the first operating system and the second operating system may be selected as the primary operating system based on a user operation, and shared hardware resources that are not accessed by the first operating system and the second operating system at the same time may be allocated to the primary operating system. Here, the resources such as the camera are allocated to a specific operating system based on a user instruction, considering that the dual system cannot implement shared access based on an instruction cache manner.
Here, the mobile terminal may include, but is not limited to: a feature phone, a smart phone, a palm top, a tablet or a Personal Digital Assistant (PDA), etc. The first operating system may be operated on a first screen while the second operating system is operated on a second screen. For example, the first operating system is a living operating system, which is a master operating system, and the second operating system is a secure operating system, which is a slave operating system.
Although specific examples of mobile terminals are listed above in detail, those skilled in the art will appreciate that these lists are merely illustrative and are not intended to limit the scope of embodiments of the present invention. The mobile terminal can be applied to any intelligent terminal operating system, and specific applicable operating systems include but are not limited to: android (Android), Palm OS, Symbian (Saiban), Windows mobile, Linux, Android (Android), iPhone (apple) OS, Black Berry (blackberry) OS 6.0, Windows Phone series, and so forth.
