Example one
The embodiment of the invention provides a method for sharing Bluetooth by multiple systems, which comprises the following steps as shown in figure 2:
step 201, when any subsystem detects the bluetooth resource request message, respectively sending a notification message to other subsystems.
The notification message includes information that any subsystem needs to occupy the bluetooth resource.
For the embodiment of the invention, when a first subsystem in the terminal equipment needs to perform information interaction with other terminal equipment, the first subsystem sends a notification message to other subsystems in the terminal equipment to inform the other subsystems that the subsystem needs to occupy Bluetooth resources.
Step 202, when any subsystem receives feedback messages which are returned by all other subsystems and respond to the notification messages, a Bluetooth resource request message is sent to the Bluetooth driver.
Wherein, the feedback message comprises the information that the subsystem sending the feedback message does not occupy the Bluetooth resource.
For the embodiment of the invention, after acquiring the notification message sent by the first subsystem, other subsystems determine whether the other subsystems currently occupy the Bluetooth resource. In the embodiment of the invention, if the Bluetooth resource is not occupied currently, a feedback message is returned to the first subsystem, if the Bluetooth resource is occupied currently, whether the Bluetooth resource is released or not is determined, wherein if the Bluetooth resource is determined to be released and successfully released, the feedback message is returned to the first subsystem.
For the embodiment of the invention, when the first subsystem acquires the feedback messages returned by all other subsystems, the Bluetooth service in the first subsystem sends the Bluetooth resource request message to the Bluetooth driver through the Bluetooth proxy service in the first subsystem. When the first subsystem receives feedback messages returned by all other subsystems, the Bluetooth resources are not occupied by other subsystems currently.
And 203, any subsystem receives the Bluetooth resource sent by the Bluetooth driver so as to perform information interaction with other terminal equipment through the Bluetooth resource.
Compared with the prior art, the embodiment of the invention provides a method for sharing Bluetooth by multiple systems, which sends notification messages to other subsystems when any subsystem detects a Bluetooth resource request message, and when receiving a feedback message that other subsystems do not occupy the Bluetooth resource, requesting the Bluetooth drive for the Bluetooth resource so as to perform information interaction with other terminal equipment according to the obtained Bluetooth resource, that is, when any subsystem needs to occupy the bluetooth resource to perform information interaction with other terminal devices, only when no other subsystem occupies the bluetooth resource, the bluetooth resource needs to be requested, therefore, each subsystem in the multi-system terminal equipment can allocate the Bluetooth resources according to the mode, carry out information interaction with other terminal equipment, therefore, the problem of information interaction between the multi-system terminal equipment and other terminal equipment can be solved.
Example two
Another possible implementation manner of the embodiment of the present invention is, on the basis of the first embodiment, that in step 201, when any subsystem detects a bluetooth resource request message, the notification message is respectively sent to other subsystems, including steps 301 and 302 in the second embodiment, where the operations performed in steps 303 and 304 are similar to those performed in steps 202 and 203, and are not described herein again.
Step 301, when any subsystem detects a bluetooth resource request, writing a notification message into a file device node of the master control system.
For the embodiment of the invention, each subsystem in the multi-system terminal equipment is provided with the Bluetooth service and the Bluetooth service agent.
For the embodiment of the present invention, a file device node is provided in the main control system, and all subsystems in the terminal device can access the file device node. In the embodiment of the invention, when the Bluetooth service agent of a certain subsystem detects the Bluetooth resource request message issued by the Bluetooth service, the notification message is written into the file device node in the main control system, so that the Bluetooth agent services in other subsystems in the terminal device can read the notification message from the file device node in the main control system. Wherein, the notification message may carry an identifier of a system that notifies a sender of the message.
For example, the terminal device runs three subsystems, namely a first subsystem, a second subsystem and a third subsystem, and if the bluetooth proxy service in the first subsystem detects a bluetooth resource request message issued by the bluetooth service in the system, a notification message carrying the system identifier of the first subsystem is written into a file device node of the master control system.
Step 302, the other subsystems read the notification message from the file device node of the main control system respectively.
For example, the second subsystem and the third subsystem may each read the notification message written by the first subsystem from the file device node of the master control system.
For the embodiment of the present invention, any subsystem writes the notification message into the file device node of the main control system, so that other subsystems in the terminal device can read the written notification message from the file device node of the main control system, that is, other subsystems can know the subsystem currently needing to occupy the bluetooth resource, thereby providing a precondition for the subsystem needing to occupy the bluetooth resource to acquire the bluetooth resource.
EXAMPLE III
Another possible implementation manner of the embodiment of the present invention is, on the basis shown in the first embodiment, in step 201, when any subsystem detects a bluetooth resource request message, the method further includes step 401 and step 402 shown in the third embodiment, in step 202, when any subsystem receives feedback messages responding to the notification message returned by all other subsystems, the method sends the bluetooth resource request message to the bluetooth driver, including step 404 shown in the third embodiment, where operations executed in steps 403 and 405 are similar to those executed in steps 201 and 203, and are not described again here.
Step 401, any subsystem sends a request message for creating a channel to the master control system.
The creating channel request message is used for requesting to create a communication channel between the creating channel request message and the master control system.
For the embodiment of the invention, the mobile terminal runs with a plurality of subsystems and is also provided with a main control system for managing the subsystems, and when a certain subsystem needs to perform information interaction with the main control system, a channel creating request message is sent to the main control system so as to perform information interaction between the subsystem and the main control system. Wherein, the request message for creating the channel carries the system identifier of the sender of the request message for creating the channel.
For example, when a first subsystem in the terminal device needs to request the master control system to create a communication channel, a create channel request message carrying a first subsystem identifier is sent to the master control system, so that the master control system creates a communication channel between the first subsystem and the master control system.
Step 402, the master control system creates a communication channel between any subsystem and the master control system.
For the embodiment of the invention, the master control system creates two socket file descriptors according to the created channel request message, so that the subsystem sends the Bluetooth resource request message to the Bluetooth driver of the master control system through the created socket file descriptors.
And step 404, when any subsystem receives feedback messages responding to the notification messages returned by all other subsystems, sending a bluetooth resource request message to the bluetooth driver in the master control system through the created communication channel.
For the embodiment of the invention, when other subsystems in the terminal equipment do not occupy the Bluetooth resources currently or successfully release the Bluetooth resources, the feedback message is written in the file equipment node in the master control system, so that the system of the notification message sender reads the feedback message.
For the embodiment of the invention, the master control system is provided with the Bluetooth service and the Bluetooth driver, when a sender system of the notification message reads the feedback messages written by all other subsystems from the file device node of the master control system, the Bluetooth agent service in the subsystem of the sender of the notification message sends the Bluetooth resource request message to the master control system through the socket file descriptor, so that the Bluetooth service of the master control system sends the received Bluetooth resource request message to the Bluetooth driver. In the embodiment of the invention, after the bluetooth driver receives the bluetooth request message, the corresponding bluetooth resource is sent to the first subsystem through the bluetooth service in the master control system.
For example, when the first subsystem reads a feedback message written by the second subsystem and the third subsystem from a file device node of the master control system, the bluetooth proxy service in the first subsystem sends a bluetooth resource request message to the master control system through the socket file descriptor, and after receiving the bluetooth request message, the bluetooth service in the master control system sends the bluetooth resource request message to the bluetooth driver, so that the bluetooth driver sends the corresponding bluetooth resource to the bluetooth service in the master control system and sends the corresponding bluetooth resource to the first subsystem through the socket file descriptor.
For the embodiment of the invention, the master control system can enable the subsystem to send the Bluetooth resource request message to the master control system through the established communication channel by establishing the communication channel between the subsystem and the master control system, and can transmit the Bluetooth resource sent by the Bluetooth driver to the subsystem needing to occupy the Bluetooth resource through the established communication channel, thereby providing possibility for each subsystem to acquire the Bluetooth resource.
Example four
Another possible implementation manner of the embodiment of the present invention is, on the basis of the third embodiment, that in step 404, when any subsystem receives feedback messages in response to the notification message, which are returned by all other subsystems, the bluetooth driver in the master control system sends the bluetooth resource request message through the created communication channel, and before that, the method further includes step 504 shown in the fourth embodiment, where operations executed in steps 501 and 503 and 505 and 506 are similar to those executed in step 401 and 405, and are not described herein again.
Step 504, when the subsystem receiving the notification message is currently occupying the bluetooth resource, releasing the bluetooth resource according to the indication information input by the user, and returning a feedback message to any subsystem.
For the embodiment of the invention, when the subsystem receiving the notification message occupies the Bluetooth resource currently, the terminal equipment can display the prompt message, and the user can input the indication information according to the prompt message. In the embodiment of the invention, if the subsystem receives the indication information input by the user and agrees to release the Bluetooth resource of the subsystem, the subsystem releases the Bluetooth resource and writes the feedback message into the file device node in the master control system, so that the notification message sender subsystem reads the corresponding feedback message from the file device node; if the sub-system receives the indication information input by the user and does not agree to release the Bluetooth resource of the sub-system, the sub-system can occupy the Bluetooth resource all the time and does not write the feedback information into the file device node of the main control system.
For the embodiment of the invention, when the subsystem receiving the notification message currently occupies the Bluetooth resource, whether the Bluetooth resource is released or not is determined through the indication information input by the user, namely, the terminal equipment only supports one subsystem to occupy the Bluetooth resource, and whether the subsystem of the notification message sender is allowed to occupy the Bluetooth resource or not can be determined through the indication information input by the user, so that interruption of important information being transmitted by the user due to release of the Bluetooth resource without user agreement can be avoided, and the user experience can be further improved.
EXAMPLE five
Another possible implementation manner of the embodiment of the present invention is, on the basis of the third embodiment, that in step 404, when any subsystem receives feedback messages in response to the notification message, which are returned by all other subsystems, the bluetooth driver in the master control system sends the bluetooth resource request message through the created communication channel, and step 604 and 605 shown in the fifth embodiment are further included before the present invention, where operations executed in steps 601 and 603 and 606 and 607 are similar to those executed in step 401 and 405, and are not described herein again.
And step 604, when the subsystem receiving the notification message currently occupies the bluetooth resource, determining whether to release the bluetooth resource currently according to the application identifier carried by the notification message and the priority of the bluetooth resource occupied by the application.
For the embodiment of the invention, each subsystem of the terminal equipment can set the priority information of each application occupying the Bluetooth resource in each subsystem, and the notification message sent by the notification message sender can carry the identifier of the application needing to occupy the Bluetooth resource. In the embodiment of the invention, the system currently occupying the Bluetooth resources determines whether to occupy the Bluetooth resources currently according to the application currently occupying the Bluetooth resources, the application identifier needing to occupy the Bluetooth resources and the preset priority information of the Bluetooth resources occupied by each application.
For the embodiment of the invention, the priority of the application occupying the Bluetooth resource can be set by the user equipment or the terminal equipment. The present invention is not limited to the embodiments.
Step 605, if the priority of the application currently occupying the bluetooth resource is lower than the priority of the application occupying the bluetooth resource corresponding to the application identifier carried in the notification message, releasing the bluetooth resource, and returning a feedback message to any subsystem.
For example, applications running in the terminal device include: the system comprises a video application, an instant messaging application and an album, wherein the video application, the album and the instant messaging application are sequentially arranged according to the priority level of the occupied Bluetooth resource from high to low, if the application occupying the Bluetooth in the system occupying the Bluetooth resource is the instant messaging application, the application corresponding to the application identifier carried in the notification message is the video application, the system occupying the Bluetooth resource releases the Bluetooth resource and writes a feedback message in a file device node in the master control system.
For the embodiment of the invention, if the priority of the application occupying the Bluetooth resource is higher than that of the Bluetooth resource occupied by the application corresponding to the application identifier carried in the notification message, the Bluetooth resource is not released, and the feedback message is not sent.
For the embodiment of the present invention, the subsystem currently occupying the bluetooth resource determines whether to release the bluetooth resource by carrying the application corresponding to the application identifier, the application currently occupying the bluetooth resource, and the priority corresponding to the application occupying the bluetooth resource in the read notification message, that is, determining whether to release the bluetooth resource according to the importance degree of the information being processed in the application or the importance degree of the application to the user, so as to avoid interruption of the information being transmitted by the more important application through bluetooth, and further improve user experience.
EXAMPLE six
Another possible implementation manner of the embodiment of the present invention is, on the basis of the third embodiment, that in step 404, when any subsystem receives feedback messages in response to the notification message, which are returned by all other subsystems, the bluetooth driver in the master control system sends the bluetooth resource request message through the created communication channel, and step 704 and step 705 shown in the sixth embodiment are also included before, where operations executed in steps 701 and 706 and 707 are similar to those executed in step 401 and step 405, and are not described herein again.
Step 704, when the subsystem receiving the notification message currently occupies the bluetooth resource, determining whether to release the bluetooth resource currently according to the priority information of the bluetooth resource occupied by the subsystem.
For the embodiment of the invention, priority information of each subsystem occupying Bluetooth resources is set in each subsystem of the terminal equipment. In the embodiment of the invention, the priority information of the Bluetooth resource occupied by each subsystem can be set by a user or a terminal device. The present invention is not limited to the embodiments.
For the embodiment of the invention, the subsystem currently occupying the Bluetooth resource determines whether the priority of the Bluetooth resource occupied by the subsystem corresponding to the system identifier carried in the notification message is greater than the priority of the Bluetooth resource occupied by the subsystem of the subsystem so as to determine whether to release the Bluetooth resource occupied by the system of the subsystem.
Step 705, if the priority of the bluetooth resource occupied by the subsystem currently occupying the bluetooth resource is lower than the priority of the bluetooth resource occupied by the subsystem sending the notification message, releasing the bluetooth resource and returning a feedback message to any subsystem.
For example, the terminal device may operate three subsystems, which are a first subsystem, a second subsystem and a third subsystem, respectively, where the first subsystem is a working system, the second subsystem is a learning system, and the third subsystem is a personal living system, the first subsystem, the second subsystem and the third subsystem are sequentially configured from high to low in priority of occupying bluetooth resources, and if the current subsystem occupying bluetooth resources is the second subsystem, when the second subsystem reads a notification message written in the first subsystem from a file device node of the master control system, the bluetooth resources occupied by the second subsystem is released, and a feedback message is returned.
