A frame schematic diagram of an internal structure of a terminal device according to an embodiment of the present invention is shown in fig. 1, and includes: a main control system and more than two subsystems.
The subsystem in the embodiment of the present invention may be a container system that is provided in Linux container virtualization technology. The container system may be a Linux operating system or a Unix operating system in the conventional sense, an Android system, an Ubuntu system or a FireFox system derived from the Linux operating system, or a Windows system based on a Windows platform. In fact, the system of the present invention is not limited to the aforementioned exemplary operating systems, and can encompass all operating systems capable of operating in a container.
Preferably, the master control system may be the above conventional operating system, and may also be an operating system obtained by modifying the conventional kernel and/or adding functional modules outside the kernel (for example, a framework layer and an application layer).
The main control system is mainly used for performing foreground and background management on a plurality of subsystems, performing interaction with each system and the like.
Preferably, the master control system may communicate with the subsystems through predefined channels. Similarly, the systems can communicate with each other through the channel. Wherein the predefined channel may be a socket channel.
As shown in fig. 2, a method for using an Mtp function by multiple systems in an embodiment of the present invention includes:
step 201, the first subsystem sends an Mtp resource application request message to a multi-system control service in the master control system.
For the embodiment of the present invention, the Mtp resource may include: audio resources and video resources. The present invention is not limited to the embodiments.
And the Mtp resource application request message carries the system identifier of the first subsystem. For example, the system identifier of the first subsystem carried in the Mtp resource application request message is OS1。
For the embodiment of the invention, when the file in the first subsystem is transmitted to the mobile phone through a Universal Serial Bus (USB), the first subsystem first sends a request message to the multi-system control service in the main control system to request to activate the Mtp function of the first subsystem.
Step 202, the multi-system control service in the main control system detects whether the Mtp resource is occupied by other subsystems.
For the embodiment of the invention, after the multi-system control service in the main control system receives the Mtp resource application request message sent by the first container system, whether the Mtp resource is occupied by other subsystems is detected.
For the embodiment of the present invention, step 202 may further include: and if the multi-system control service in the main control system detects that the Mtp resource is occupied by other subsystems, the multi-system control service in the main control system returns a notification message that the Mtp resource is occupied by other subsystems to the first container system.
And 203, if the Mtp resources are not occupied by other subsystems, the multi-system control service in the main control system sends an activation permission request message to the Mtp function hardware equipment node of the kernel.
For the embodiment of the invention, the multi-system control service in the main control system detects whether the Mtp resource is occupied by other subsystems, so that the condition that two or more subsystems use the Mtp function at the same time to cause the conflict of the two subsystems is avoided.
For example, the Mtp resource is currently occupied by the second subsystem and the sound is output through the Mtp resource, which would result in possible output errors if the Mtp function of the first subsystem is still activated and the first subsystem is also outputting sound at the same time.
And step 204, the Mtp function hardware equipment node of the kernel activates the Mtp resource control authority of the first subsystem according to the activation authority request message.
For the embodiment of the invention, the activation permission request message received by the Mtp function hardware equipment node of the kernel generally carries a system identifier, and the Mtp function hardware equipment node of the kernel determines a subsystem needing to activate the Mtp resource control permission according to the system identifier and activates the Mtp resource control permission of the subsystem. In the embodiment of the invention, if the activation permission request message received by the Mtp function hardware equipment node of the kernel does not carry the system identifier, the Mtp function hardware equipment node of the kernel activates the Mtp resource control permission of the current foreground running subsystem.
For example, if the system identifier carried in the activation permission request message received by the Mtp function hardware device node of the kernel is the OS1If the Mtp function hardware equipment node of the kernel activates the Mtp resource control authority of the first subsystem; and if the system identifier does not exist in the activation permission request message received by the Mtp function hardware equipment node of the kernel and the subsystem operated in the foreground is the second subsystem, activating the Mtp resource control permission of the second subsystem by the Mtp function hardware equipment node of the kernel.
Compared with the method that only one system in a mobile terminal supports the Mtp function, any system of the mobile terminal in the embodiment of the invention can send an Mtp resource request message to a multi-system control service in a main control system, and after detecting that the Mtp resource is not occupied by other subsystems, the Mtp resource control authority of a first subsystem is activated, so that the first subsystem uses the Mtp function, namely each subsystem in the mobile terminal supports the Mtp function.
Another possible implementation manner of the embodiment of the present invention is, on the basis as shown in fig. 2, the step 204, the http function hardware device node of the kernel activates the http resource control authority of the first subsystem according to the activation authority request message, and then further includes a step 305 as shown in fig. 3, where the operation performed in the step 301 and 304 is the same as the operation performed in the step 201 and 204 in fig. 2, and is not described herein again.
Step 305, the multi-system control service in the master control system sends first notification messages to other subsystems respectively.
Wherein, the first informing message is used for informing other subsystems that Mtp resources are occupied.
For the embodiment of the invention, after the Mtp function hardware device node of the kernel activates the Mtp resource control authority of the first subsystem, the multi-system control service in the main control system respectively sends notification messages to other subsystems in the mobile terminal. In the embodiment of the present invention, the first notification message may or may not carry the system identifier of the first subsystem. The present invention is not limited to the embodiments.
For the embodiment of the invention, the multi-system control service in the main control system respectively sends the first notification message to other subsystems to notify the other subsystems that the Mtp resources are occupied, so that the situation that the other subsystems send Mtp resource application request messages to the multi-system control service in the main control system can be avoided, and the signaling overhead can be reduced.
Another possible implementation manner of the embodiment of the present invention is as shown in fig. 3, and further includes steps 406 and 408 as shown in fig. 4, wherein the operations performed in the steps 401 and 405 are the same as the operations performed in the steps 301 and 305, and are not described herein again.
And step 406, when the first subsystem does not need to use the Mtp resource, the first subsystem sends an Mtp resource cancellation message to a multi-system control service of the main control system.
For the embodiment of the invention, after the first subsystem in the mobile terminal and other mobile systems complete data transmission, the first subsystem sends an Mtp resource cancellation message to the multi-system control service of the main control system so as to cancel the Mtp resource control authority of the first subsystem.
For the embodiment of the present invention, the Mtp resource cancellation message may or may not carry the system identifier of the first subsystem. The present invention is not limited to the embodiments.
Step 407, the multi-system control service of the main control system sends a permission canceling request message to the Mtp function hardware device node of the kernel.
And step 408, the Mtp function hardware equipment node of the kernel cancels the Mtp resource control authority of the first subsystem according to the authority canceling request message.
For example, when the permission cancellation request message received by the Mtp function hardware device node of the kernel carries the OS1When the Mtp function hardware equipment node of the kernel directly cancels the Mtp resource control authority of the first subsystem; when the permission canceling request message received by the Mtp function hardware device node of the kernel does not carry the system identifier, the Mtp function hardware device node of the kernel can check the subsystem occupying the Mtp resource currently and cancel the Mtp resource control permission of the subsystem.
For the embodiment of the invention, when the first subsystem does not need to use the Mtp resource, the first subsystem sends the permission canceling request message to the Mtp function hardware equipment node of the kernel through the multi-system control service of the main control system, so that the Mtp function hardware equipment node of the kernel cancels the Mtp resource control permission of the first subsystem, other subsystems can apply for the Mtp resource, the first subsystem is prevented from occupying the Mtp resource when the Mtp resource does not need to be used, and the waste of the Mtp resource can be reduced.
Another possible implementation manner of the embodiment of the present invention is, on the basis as shown in fig. 4, the step 408, the Mtp function hardware device node of the kernel, according to the cancellation permission request message, cancels the Mtp resource control permission of the first subsystem, and then further includes a step 509 as shown in fig. 5, where the operation performed in the steps 501-508 is the same as the operation performed in the steps 401-408, and is not described herein again.
Step 509, the multi-system control service of the main control system sends a second notification message to the other subsystems.
The second informing message is used for informing other subsystems that the current Mtp resource is idle, so that the other subsystems can apply for occupying the Mtp resource.
For the embodiment of the present invention, the second notification message may carry a system identifier to notify that the first subsystem of the other subsystems does not occupy the http resource currently, or may not carry the system identifier to notify that the current http resource of the other subsystems is idle. The present invention is not limited to the embodiments.
For the embodiment of the invention, the multi-system control service of the main control information sends the second notification message to other subsystems, so that the idle state of the Mtp resource of other subsystems can be notified, other subsystems can apply for occupying the Mtp resource in time, the waiting time of the Mtp resource occupied by other subsystems can be avoided, the waiting time of the user using the Mtp function of other subsystems can be further reduced, and the user experience is improved.
Another possible implementation manner of the embodiment of the present invention is based on the operation shown in fig. 2, where the activation permission request message carries the system identifier of the first subsystem, and the step 204 activates the mptp resource control permission of the first subsystem by the mptp function hardware device node of the kernel according to the activation permission request message, including the operation 604 shown in fig. 6, and the operation shown in the step 601 and 603 is the same as the operation shown in the step 201 and 203, and is not described herein again.
And step 604, activating the Mtp resource control authority of the first subsystem by the Mtp function hardware equipment node of the kernel according to the system identifier of the first subsystem in the activation authority request message.
The embodiment of the invention provides another method for using Mtp resources by multiple systems, which is characterized in that first notification messages are respectively sent to other subsystems through multiple system control services in a main control system to notify the other subsystems that Mtp resources are occupied, so that the situation that the other subsystems send Mtp resource application request messages to the multiple system control services in the main control system can be avoided, and the signaling overhead can be reduced; when the first subsystem does not need to use the Mtp resource, the first subsystem sends an authority cancelling request message to the Mtp function hardware equipment node of the kernel through the multi-system control service of the master control system, so that the Mtp function hardware equipment node of the kernel cancels the Mtp resource control authority of the first subsystem, other subsystems can apply for the Mtp resource, the Mtp resource is prevented from being occupied when the first subsystem does not need to use the Mtp resource, and the waste of the Mtp resource can be reduced; the multi-system control service of the main control information sends a second notification message to other subsystems, and can notify that the Mtp resources of the other subsystems are idle, so that the other subsystems can apply for occupying the Mtp resources in time, waiting time of the Mtp resources occupied by the other subsystems can be avoided, waiting time of users using the Mtp functions of the other subsystems can be reduced, and user experience is improved.
