To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
The terms referred to in this application are introduced as follows:
container technology is a very practical kernel virtualization technology that can provide lightweight virtualization to isolate processes and resources. By means of container technology and by means of namespace (namespace) technology and control group (Cgroup) technology plus some extra system-to-system separation technology, the running support environment of multiple systems on the same equipment can be provided at the same time, and therefore multiple different types of system applications can be supported.
Container technology isolates processes, networks, messages, file systems, UTS (UNIX Time-sharing systems) and users located between different containers by using a namespace mechanism. For the systems in each container, they all think they are running independently on a dedicated handset platform.
Virtualization refers to the ability to simulate multiple virtual machines on the same physical server, and each virtual machine logically has an independent central processing unit, memory, hard disk, network interface, and the like. Virtualization can improve the utilization rate of hardware resources, so that a plurality of applications can run on the same physical machine in an isolated manner.
The control group (Cgroups) mechanism is a mechanism provided by the Linux kernel that can limit, record, and isolate physical resources (e.g., central processing units, memory, disk input and output, etc.) used by a process group. It is a function of the Linux kernel to limit, count and separate the resources (e.g., central processing unit, memory, disk input and output, etc.) of a process group.
The container technique controls the resource allocation and usage on the terminal device as a whole by the Cgroups technique. For example, if the cpu occupation of the restricted process/bin/sh is 20%, a Cgroup with a cpu occupation of 20% may be created, and then the/bin/sh process is added to the Cgroup.
In the present multisystem terminal device, either the MTP function is fixed to a certain system or the MTP function is fixed to a foreground system, however, the MTP function is fixed to a certain system, which results in that other systems in the terminal device cannot use the MTP function to perform file transfer, and the MTP function is fixed to the foreground system, which results in that when the system in the terminal device is switched between the foreground and the background, the functions of two operating systems need to be changed, the foreground system supporting the MTP function is changed to not support the MTP function, the background system not supporting the MTP function is changed to support the MTP function, which greatly reduces the convenience of using the MTP function for the user, and at present, there is no implementation scheme that a plurality of systems simultaneously support the MTP function.
The application provides a method, an apparatus, an electronic device and a computer-readable storage medium for multi-system use of MTP function, which aim to solve the above technical problems in the prior art.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Example one
An embodiment of the present application provides a method for using MTP functions by multiple systems, as shown in fig. 1, including:
step S100, one MTP module of the multi-system terminal equipment is processed into MTP modules corresponding to the number of the systems.
Specifically, MTP (Media Transfer Protocol) is a Protocol provided by microsoft and customized for transferring multimedia information such as images and music between a computer and a portable device. The MTP can be implemented on a USB (Universal Serial Bus) Protocol, or a TCP/IP (Transmission Control Protocol/Internet Protocol), which belongs to an upper application Protocol, and does not concern a lower transport Protocol.
Further, the application of MTP has two roles, one is as Initiator (Initiator) and the other is as Responder (Responder). All requests in the MTP are initiated by an Initiator, for example, a desktop computer requests to acquire file data on an android phone, and a response will process the request of the Initiator and in addition, the response will also send an MTP event.
For example: WMP (Windows Media Player) is the Initiator, and the portable Media Player device is the Responder. The Responder is mainly a command for passively replying to an Initiator, generally does not actively issue the command, is mainly used for transmitting media files, associates metadata from (to) a device (a portable media player device), has optional additional support for remote control of the device, reads and sets device parameters, and can also send an MTP event to a host (such as a Windows media player).
Further, the multi-system terminal device includes, but is not limited to, an android mobile phone, a tablet computer, a laptop computer, a desktop computer, and the like, and taking an android mobile phone (hereinafter referred to as a mobile phone) as an example, only one MTP module is implemented in a current mobile phone, and the mobile phone can perform multimedia file transmission with a PC such as a tablet computer, a laptop computer, a desktop computer, and the like through the MTP module. Communication between a mobile phone and a PC is shown in fig. 2, the left side in fig. 2 is the PC, the right side is the mobile phone, the PC is connected to the mobile phone through a USB bus, the bottom layer is a USB hardware device used for communication between two devices, the mobile phone uses a USB gap mode, the USB gap mode can allow a device (for example, a mobile phone) using the mode to be used as a USB slave device, thereby providing functions similar to a USB serial port, a USB network, and the like, the PC uses a USB Host mode, the USB Host mode can allow a device (for example, a PC) using the mode to be used as a USB master device, thereby communicating with a USB slave device connected to the USB master device through the USB bus, and based on the working mode, the mobile phone can selectively implement: the adb function, the adb function is the external debugging bridge function that the android mobile phone provided, can debug and operate this cell-phone through the PC that is connected with the android mobile phone through this function), MTP functional module etc. also have corresponding adb functional module on the corresponding PC, MTP functional module etc. these modules are established on the communication mechanism that figure 2 shows to realize the communication between two modules through this mechanism, thereby realize the MTP function.
Further, the communication hierarchy at the mobile phone side is shown in fig. 3, where the MTP module is a module in which various series of modules and mass storage modules are arranged in parallel, and these modules are all built on the USB composite framework, and they all communicate with the PC at the opposite end through the USB composite framework, the UDC core (USB Device Controller), and the USB Device Controller, where the UDC core is a driver of the underlying hardware Controller on the USB hardware Device outside the USB host Controller, and the hardware and the driver are responsible for attaching a USB Device to a USB host Controller.
Further, since two, three or more systems may be operated in one mobile phone, for example, two systems are operated in the mobile phone, and the two systems may be a security system and a living system, respectively, at this time, in the dual-system mobile phone, the two systems share one Linux kernel but have respective system layers, and the MTP function includes a kernel part and a system part, where the kernel part only includes an MTP module, it is necessary to select which system the MTP module is configured to serve, that is, configure the MTP module to be used as a foreground system or a background system, that is, configure the MTP module to be used as a security system or a living system.
Furthermore, in order to enable two systems in one mobile phone to simultaneously use the MTP function, two MTP modules need to be provided in the kernel, one MTP module is allocated to the security system and the other MTP module is allocated to the living system, the security system can share files which need to be shared by the security system through the driver of the corresponding MTP module, and the living system can also share files which need to be shared by the living system through the driver of the corresponding MTP module. It should be noted that, when there are three or more systems in a mobile phone, MTP modules corresponding to the number of the systems may be provided in the kernel so that each system can use the MTP function at the same time. The MTP function block diagram inside the android mobile phone system is shown in fig. 4.
Further, for the dual-system mobile phone side, although there is still one USB device presented to the PC, the mobile phone presents two MTP interfaces to the PC, for example, one MTP interface is a previous MTP interface (corresponding to the MTP driver in fig. 4) of the mobile phone system, and the other is a new USB interface (corresponding to the USB driver in fig. 4), and the new USB interface is used to support the MTP function of the other system of the mobile phone, that is, the mobile phone can present different MTP functions to the PC through different MTP interfaces, that is, the mobile phone presents two MTP functions to the PC through the two interfaces, as shown in fig. 5. Correspondingly, the PC side needs to identify the two MTP interfaces respectively, and establish communication with the mobile phone through corresponding driver, protocol and application modules, thereby implementing content sharing.
Step S200, establishing MTP communication channels between each MTP module and the corresponding system, wherein the MTP communication channels are mutually isolated.
Specifically, after one MTP module of the multi-system terminal device is processed into MTP modules corresponding to the number of the systems, in order to ensure that each system can normally use the MTP module and the PC to perform file transmission at the same time, it is necessary to establish MTP communication channels isolated from each other between each MTP module and the corresponding system, and each system is not interfered with each other, so that a foundation is laid for each system to perform file transmission with the PC through the MTP module corresponding to the system and the MTP communication channels independent from each other.
Step S300, MTP information transmission is carried out between the MTP communication channel and each system after the establishment.
Specifically, the MTP information transmission with each system includes any one of the following cases: responding to the request of the PC to acquire the file data of any system in the mobile phone and performing MTP information transmission with each system; the core at the bottom layer of the mobile phone actively reports the MTP information to any system, and MTP information transmission is carried out between the core and each system, which is similar to the above-mentioned Responder actively sending the MTP event.
Compared with the prior art, the method for using the MTP function by the multiple systems has the advantages that one MTP module of the multiple system terminal equipment is processed into the MTP modules corresponding to the number of the systems, so that the multiple systems of the terminal equipment can simultaneously support the MTP function, and the precondition guarantee is provided for each system to carry out information transmission with other electronic equipment through the USB interface; establishing MTP communication channels between each MTP module and the corresponding system, wherein the MTP communication channels are isolated from each other, and laying a foundation for the subsequent systems to transmit MTP information through the corresponding MTP modules and the corresponding MTP communication channels respectively; through the MTP communication channel after establishing, carry out MTP information transmission with each system for terminal equipment can carry out MTP information transmission through corresponding MTP module and MTP communication channel with its each system simultaneously, each system of not only having guaranteed terminal equipment can normally use the MTP function simultaneously, even when each system carries out the front and back switching, can not influence each system and to the normal use of MTP function yet, and greatly improve the convenience that the user used the MTP function, promote user experience.
Example two
The embodiment of the present application provides another possible implementation manner, and on the basis of the first embodiment, the method shown in the second embodiment is further included, wherein,
step S300 includes step S3001 (not shown) and step S3002 (not shown), wherein,
step S3001: when any MTP module needs to send MTP information, the MTP information is sent to a system corresponding to the MTP module through each MTP module and the corresponding MTP communication channel.
Step S3002: when a request message of MTP information from an application layer is received, determining an MTP communication channel corresponding to the MTP information based on the request message; and according to the MTP communication channel obtained by determination, requesting the MTP information to a corresponding system.
Wherein, the request message carries the system identification of the system; determining an MTP communication channel corresponding to the MTP information based on the request message, comprising: determining a system to which the MTP information belongs according to the system identification; and determining an MTP communication channel corresponding to the system to which the MTP information belongs.
Specifically, after determining the MTP communication channel corresponding to the system to which the MTP information belongs, the method further includes: and binding the system to which the MTP information belongs and the MTP communication channel corresponding to the system.
Further, when the core of the bottom layer of the mobile phone actively reports the MTP information to any system, that is, each MTP module in the core of the bottom layer of the mobile phone actively sends or reports the MTP information, the MTP communication channels respectively corresponding to each MTP module may be determined according to the one-to-one correspondence relationship between the MTP module and the MTP communication channels, and then the MTP information to be sent by each MTP module is sent to the system respectively corresponding to each MTP module through the MTP communication channels respectively corresponding to each MTP module.
Furthermore, the MTP modules and the MTP communication channels are in one-to-one correspondence, for example, MTP module 1 corresponds to MTP communication channel 1, MTP module 2 corresponds to MTP communication channels 2 and …, and MTP module N corresponds to MTP communication channel N, or of course, MTP module 1 corresponds to MTP communication channel 3, MTP module 2 corresponds to MTP communication channels 5 and …, and MTP module N corresponds to MTP communication channel N. Taking an example that MTP module 1 corresponds to MTP communication channel 1 and MTP module 2 corresponds to MTP communication channel 2, when MTP module 1 and MTP module 2 in a kernel at a bottom layer of a mobile phone actively transmit or notify MTP information, according to a one-to-one correspondence relationship between MTP module and MTP communication channels, it can be determined that MTP communication channel corresponding to MTP module 1 is MTP communication channel 1 and MTP communication channel corresponding to MTP module 2 is MTP communication channel 2, and then MTP information to be transmitted by MTP module 1 is transmitted to a system (e.g., system 1) corresponding to MTP module 1 through MTP communication channel 1, and MTP information to be transmitted by MTP module 2 is transmitted to a system (e.g., system 2) corresponding to MTP module 2 through MTP communication channel 2.
Further, when the PC requests to acquire file data on the multi-system mobile phone, that is, the PC initiates an Initiator request to the multi-system mobile phone, the Initiator request may be sent to the multi-system mobile phone through an interface of an application layer of the multi-system mobile phone, that is, a request message requesting to acquire the MTP information may be sent to the multi-system mobile phone through an interface of an application layer of the multi-system mobile phone. For the PC, it needs to indicate the system to which the MTP information to be acquired belongs in the request message, for example, the request message carries the system identifier of the system to which the MTP information to be acquired belongs.
Further, when the multi-system mobile phone application layer receives the request message of the MTP information, the multi-system mobile phone determines a system corresponding to the system identifier according to the system identifier carried in the request message. The system identifiers are in one-to-one correspondence with the systems, for example, system identifier 1 corresponds to system 1, system identifier 2 corresponds to system 2, …, and system identifier N corresponds to system N, but system identifier 1 may also correspond to system 3, system identifier 2 corresponds to system 5, …, and system identifier N corresponds to system N. Taking the case that the system identifier 1 corresponds to the system 1 and the system identifier 2 corresponds to the system 2, when the request message of the MTP information received by the multi-system mobile phone carries the system identifier 1, it can be determined that the system identifier 1 corresponds to the system 1 in the multi-system according to the one-to-one correspondence between the system identifier and the system; when the MTP information request message received by the multi-system mobile phone carries the system identifier 2, the system 2 in the multi-system corresponding to the system identifier 2 can be determined according to the one-to-one correspondence between the system identifiers and the systems.
Further, after the multi-system mobile phone determines the system corresponding to the system identifier carried in the MTP information request message received by the application layer, the system to which the MTP information belongs is determined. And then the corresponding relation between the system and the MTP communication channel can be used for determining the MTP communication channel corresponding to the MTP information.
Further, after determining the MTP communication channel corresponding to the MTP information received by the application layer, the MTP information may be obtained from the system corresponding to the MTP communication channel through the MTP communication channel, so as to respond to a request from the PC side, for example, the obtained MTP information is sent to the PC through a USB bus between the PC and the MTP communication channel.
Furthermore, after the system and the MTP communication channel corresponding to the received MTP information are determined, the system to which the MTP information belongs and the MTP communication channel corresponding to the system can be bound, so that each system in the multi-system mobile phone can normally use the respective independent MTP communication channel at the same time without mutual influence.
For the embodiment of the application, the terminal equipment can normally transmit the MTP information with each system through the corresponding MTP module and the MTP communication channel, even if each system is switched back and forth, the normal use of the MTP function by each system is not influenced, and the convenience of using the MTP function by a user is greatly improved.

step S300 is followed by step S400 (not shown) and step S500 (not shown), wherein,
step S400: and providing MTP control interfaces corresponding to the systems respectively.
Step S500: and configuring the MTP function of each system according to the detected selection operation input through the MTP control interface.
Specifically, the multi-system mobile phone may provide an MTP control interface corresponding to each system, for example, the multi-system mobile phone may provide an MTP control interface for each system, that is, each system has a corresponding MTP control interface, so that a user may configure the MTP functions of each system through the MTP control interfaces corresponding to each system according to the user's own needs.
Furthermore, the multi-system mobile phone can configure the MTP function of each system according to the detected selection operation input through the MTP control interface, that is, when the multi-system mobile phone detects the input selection operation of the user on the MTP control interface of any system (for example, system 1), the multi-system mobile phone can configure the MTP function of any system (for example, system 1) according to the input selection operation of the user, so that the user can conveniently and quickly configure each system through the MTP control interface corresponding to each system according to the different requirements of the user on each system.
For the embodiment of the application, a user can configure each system according to own requirements through the MTP control interface corresponding to each system, so that each system meets different requirements of the user, and the user experience is greatly improved.
