Description
Technical Field
The embodiment of the invention relates to the technical field of terminal equipment, in particular to an attribute synchronization method and device.
Background
At present, terminal devices such as smart phones, tablet computers, electronic readers and the like are widely popularized. With the increase of the hardware level of the intelligent terminal, the processing capacity of the intelligent terminal is enhanced, and many intelligent terminals can run two or more operating systems. Among these operating systems, the operating system that the user is using is referred to as the current operating system, and the other operating systems other than the current operating system are referred to as the background operating systems.
The property (property) of the operating system is used to record the operating system settings or information interaction between processes, and manage various configurations and states of the operating system, and is essentially an inter-process communication (IPC) means for accessing and sharing data in time and space. In general, each of a plurality of operating systems of a terminal device has a set of attributes, and in different operating systems, some of the attributes are the same and some of the attributes are different. For example, the terminal device runs an operating system a and an operating system B at the same time, the operating system a having an attribute 1, an attribute 2, and an attribute 3, and the operating system B having an attribute 2, an attribute 3, and an attribute 4.
In general, a user sets attributes of different operating systems, respectively, so that the operating systems reach a state desired by the user. However, in some scenarios, the attribute of the current operating system needs to be synchronized to the background operating system, and the above example is continued, assuming that the user modifies the attribute 2 and the attribute 3 of the operating system a, if the attribute 2 and the attribute 3 of the operating system B need to be modified synchronously, the user needs to perform system switching, switch the current operating system from the operating system a to the operating system B, and then modify the attribute 2 and the attribute 3 of the operating system B. When the attributes required to be synchronized are more and the modification frequency of the attributes is higher, the attribute synchronization method switched by the system has the disadvantages of complicated steps, complex process and easy error.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Typically, some attributes of the operating system need to be modified synchronously, wherein the attributes include which Subscriber Identity Module (SIM) card to access the internet, etc. For example, a terminal device supporting dual card and dual standby is provided with a Subscriber Identity Module (SIM) card 1 and a SIM card 2, the terminal device has two operating systems, namely an operating system a and an operating system B, when the operating system currently running in the terminal device is the operating system a, the terminal device accesses the internet through the SIM card 1, and performs services such as making a call through the SIM1 card; when the operating system currently running by the terminal device is operating system B, the terminal device accesses the internet through SIM card 1, but performs service access such as making a call through SIM 2. If the user needs to modify the internet access through the SIM card 1 into the internet access through the SIM card 2, if the currently running operating system is the operating system a, the user modifies the attribute of the operating system a, so that when the operating system of the terminal device is the operating system a, the terminal device accesses the internet through the SIM2, then the terminal device performs operating system switching according to the instruction of the user, switches to the operating system B, and the user modifies the attribute of the operating system B, so that when the operating system of the terminal device is the operating system B, the terminal device accesses the internet through the SIM 2.
In the attribute modification process, the attribute needing to be synchronized is modified by executing the switching of the operating system. However, when there are many attributes to be synchronized and the modification frequency of the attributes is high, the above method for synchronizing the attributes by switching through the operating system has complex steps, complex process and is prone to errors.
In view of this, the embodiment of the present invention provides an attribute synchronization method, which does not need to perform switching of an operating system during attribute synchronization, and has a simple process and high accuracy.
Embodiments of the present invention are applicable to terminal devices that support multiple operating systems, which are devices capable of providing voice and/or data connectivity to a user, handheld devices with wireless connectivity, or other processing devices connected to a wireless modem. In this embodiment of the present invention, the terminal device may include: a cellular or other communication device having a single line display or a multi-line display or a cellular or other communication device without a multi-line display; personal Communications Systems (PCS) having voice, data processing, facsimile and/or data communications capabilities; personal Digital Assistants (PDAs), which may include radio frequency receivers, pagers, internet/intranet access, web browsers, notepads, calendars, and/or GPS (Global Positioning System) receivers; a conventional laptop and/or palmtop computer or other device having and/or including a radio frequency receiver. As used herein, a "terminal" or "terminal device" may be portable, transportable, installed in a vehicle (aeronautical, maritime, and/or land-based), or situated and/or configured to operate locally and/or in a distributed fashion at any other location(s) on earth and/or in space. As used herein, a "terminal device" may also be a communication terminal, a web terminal, and a music/video playing terminal, and may be, for example, a PDA, a Mobile Internet Device (MID) and/or a mobile phone with a music/video playing function, and may also be a smart tv, a set-top box, and other devices.
Fig. 1 is a schematic diagram of an operating system of a terminal device to which the attribute synchronization method provided in the embodiment of the present invention is applied. Referring to fig. 1, in the embodiment of the present invention, the terminal device supports X operating systems, for example, container systems created by using a Linux container virtualization technology, and the operating systems may be Linux operating systems or Unix operating systems in a conventional sense, or operating systems derived from the Linux operating system. The operating systems include user-oriented container systems and/or container systems that are not visible to the user. The user-oriented container system means that the terminal equipment can execute operating system switching according to the operation of a user, so that the user can set and use the operating system; the operating system which is invisible to the user cannot be visible to the user even if the user executes system operation, and the operating system can only enter a background to be modified, set and the like.
In the embodiment of the present invention, any one of X operating systems supported by a terminal device, hereinafter referred to as a first operating system, corresponds to X-1 device node files, and the device node files are stored in a kernel (kernel) space of the terminal device. For example, if X is 3, that is, the terminal device has 3 operating systems, namely, an operating system a, an operating system B, and an operating system C, then 6 device node files are created in the kernel space, namely, a device node file 1, a device node file 2, and a device node file 3 … …, where the operating system a corresponds to the device node file 1 and the device node file 2; the operating system B corresponds to the device node file 3 and the device node file 4, the operating system B corresponds to the device node files 5 and 6, and if the attribute of a certain operating system changes, the operating system writes the attribute name of the changed attribute and the changed attribute value into the device node file corresponding to the operating system. Taking the operating system a as an example, if the kernel of the terminal device detects that the attribute value of the attribute 1 of the operating system a changes, the terminal device writes the attribute value after the attribute 1 and the attribute value after the attribute 1 change into the device node file 1 and the device node file 2, respectively. Then, without executing the switching of the operating system, the monitoring process of the operating system B monitors that the content of the equipment node file 1 changes, reads the equipment node file 1, reads the attribute 1 and the changed post attribute value thereof, and modifies the attribute 1; and when the monitoring process of the operating system C monitors that the content of the equipment node file 2 changes, reading the equipment node file 2, reading the attribute 1 and the changed attribute value thereof, and modifying the attribute 1.
It should be noted that the operating system described in the embodiment of the present invention includes, but is not limited to, an exemplary operating system, and may also cover all operating systems capable of running in a container.
Next, based on the operating system framework shown in fig. 1, the attribute synchronization method according to the embodiment of the present invention will be described in detail. For example, see fig. 1.
Fig. 2 is a flowchart of an attribute synchronization method according to an embodiment of the present invention. The embodiment comprises the following steps:
101. the terminal device detects whether the attribute value of the first attribute of the first operating system changes.
Wherein the first operating system is any one of the plurality of operating systems.
In general, if a plurality of operating systems are running on a terminal device, the operating system that is being used by a user is referred to as a current operating system, and the operating systems other than the current operating system are referred to as background operating systems.
When a user needs to synchronize the attributes of the operating systems, at this time, the first operating system is the current operating system, the user sets the attributes of the current operating system, the terminal device detects whether the first attribute, that is, any attribute of the first operating system changes, and if the first attribute changes, the step 102 is executed; if any attribute of the current operating system is not changed, the step 101 is returned to. In the process, the first operating system is a user-oriented container system, i.e., an operating system visible to the user.
When research personnel need to synchronize the attributes of the operating systems, at this time, the first operating system is a container system invisible to a user, the research personnel sets the attributes of the container system invisible to the user, the terminal device detects the first attribute of the container system invisible to the user, namely whether any one attribute of the container system invisible to the user changes, and if the any one attribute of the container system invisible to the user does not change, the step 102 is executed; if any one of the attributes of the container system that is not visible to the user has not changed, the process returns to step 101. In addition, the research and development staff may set the operating system that is not visible to the user in the background, and may set the attribute of the operating system that is visible to the user in the background.
102. If the attribute value of the first attribute changes, the terminal device writes the first attribute and a new attribute value of the first attribute into X-1 device node files corresponding to the first operating system respectively, so that the terminal device reads a device node file corresponding to a second operating system in the X-1 device node files to synchronize the first attribute, wherein the second operating system is any one of the operating systems except the first operating system.
For example, assuming that X is 3, that is, there are 3 operating systems on the terminal device, namely, the operating systems are an operating system a, an operating system B, and an operating system C, 6 device node files are created in the kernel space, namely, a device node file 1, a device node file 2, and a device node file 3 … …, where the operating system a corresponds to the device node file 1 and the device node file 2; operating system B corresponds to device node files 3 and 4 and operating system B corresponds to device node files 5 and 6. Taking the first operating system as an operating system a as an example, if a user modifies an attribute a of the operating system a, the terminal device writes new attribute values of the attribute a and the attribute a into a device node file 1 and a device node file 2. Then, the listening process of the operating system B reads the device node file 1 periodically or aperiodically, and reads new attribute values of the attribute a and the attribute a, so as to modify the attribute a of the operating system B, thereby completing the attribute synchronization of the operating system a and the operating system B without executing the switching of the operating system. Similarly, the monitoring process of the operating system C reads the device node file 1 periodically or aperiodically, and reads the new attribute values of the attribute a and the attribute a, so as to modify the attribute a of the operating system C, thereby completing the attribute synchronization of the operating system a and the operating system C without executing the switching of the operating system. That is, the attribute synchronization of the operating system a, the operating system B, and the operating system C is completed.
In the attribute synchronization method provided by the embodiment of the present invention, at least two operating systems are run on the terminal device, and after the attribute of any one operating system changes, the operating system writes the name of the attribute and the changed attribute value into the device node file corresponding to the operating system, and different device node files correspond to different operating systems, so that other operating systems read the device node files to complete attribute synchronization. In the process, attribute synchronization can be realized without executing operation system switching, and the process is simple and high in accuracy.
In the above embodiment, when the first operating system is the current operating system of the terminal device, the user modifies the attribute of the current operating system, and writes the corresponding attribute and the new attribute value into each device node file, so that the other operating systems perform attribute synchronization. In addition, when the attributes of other operating systems change, the terminal device may also perform attribute synchronization by reading the device node file. In this case, the attribute synchronization method further includes: the terminal equipment monitors whether the equipment node files corresponding to the first operating system are written into a second attribute and the attribute value of the second attribute in X-1 equipment node files corresponding to the second operating system; if the device node file corresponding to the first operating system is written into the second attribute and the attribute value of the second attribute in the X-1 device node files corresponding to the second operating system, the terminal device reads the attribute values of the second attribute and the second attribute; and the terminal equipment updates the second attribute according to the second attribute and the attribute value of the second attribute.
In the foregoing embodiment, in order to prevent that the operating system corresponding to the device node file reads the device node file for performing attribute synchronization before the first operating system unsuccessfully writes the attribute name and the new attribute value of the first attribute into the device node file, the related information of the first attribute cannot be correctly read. In the above embodiment, if the attribute value of the first attribute changes, when the terminal device writes the first attribute and the new attribute value of the first attribute into X-1 device node files corresponding to the first operating system, the terminal device performs lock protection on the X-1 device node files corresponding to the first operating system, and writes the first attribute and the new attribute value of the first attribute into X-1 device node files corresponding to the first operating system.
Illustratively, continuing with the above example, assuming that X is 3, that is, there are 3 operating systems on the terminal device, namely, operating system a, operating system B and operating system C, respectively, then 6 device node files are created in the kernel space, namely, device node file 1, device node file 2, device node file 3 … … device node file 6, where operating system a corresponds to device node file 1 and device node file 2; operating system B corresponds to device node files 3 and 4 and operating system B corresponds to device node files 5 and 6. Taking the first operating system as an operating system a as an example, if a user modifies an attribute a of the operating system a, the terminal device writes new attribute values of the attribute a and the attribute a into a device node file 1 and a device node file 2. In the writing process, the terminal device performs lock protection on the device node file 1 and the device node file 2 until the operating system a successfully writes the new attribute values of the attribute a and the attribute a into the device node file 1 and the device node file 2. Then, the listening process of the operating system B reads the device node file 1 periodically or aperiodically, and reads new attribute values of the attribute a and the attribute a, so as to modify the attribute a of the operating system B, thereby completing the attribute synchronization of the operating system a and the operating system B without executing the switching of the operating system. Similarly, the monitoring process of the operating system C reads the device node file 1 periodically or aperiodically, and reads the new attribute values of the attribute a and the attribute a, so as to modify the attribute a of the operating system C, thereby completing the attribute synchronization of the operating system a and the operating system C without executing the switching of the operating system. That is, the attribute synchronization of the operating system a, the operating system B, and the operating system C is completed.
In the foregoing embodiment, in order to prevent a device node file from being always locked and protected, after a terminal device performs lock protection on the device node file, the terminal device determines whether to write the first attribute and a new attribute value of the first attribute into a target device node file, where the target device node file is any one of X-1 device node files corresponding to the first operating system; and if the first attribute and the new attribute value of the first attribute are written into the target equipment node file, the terminal equipment releases the lock protection of the target equipment node file.
In this embodiment of the present invention, if the first operating system detects that the attribute value of the first attribute changes, the terminal device determines, during a process of writing the first attribute and a new attribute value of the first attribute into X-1 device node files corresponding to the first operating system, whether the first attribute is an attribute that needs to be synchronized to the second operating system; and if the terminal equipment detects that the attribute value of the first attribute changes and the first attribute is the attribute which needs to be synchronized to the second operating system, the terminal equipment writes the first attribute and the new attribute value of the first attribute into X-1 equipment node files corresponding to the first operating system respectively.
For example, a list may be configured on the terminal device in advance, where an attribute in the list is an attribute that needs to be synchronized, after the terminal device detects that a first attribute changes, it first determines whether the first attribute is included in the list, and if the first attribute is included in the list, the terminal device considers that the first attribute is an attribute that needs to be synchronized, and the terminal device needs to write the first attribute and a new attribute value of the first attribute into the device node file; otherwise, if the first attribute is not included in the list, the first attribute is considered to be not an attribute which needs to be synchronized, and the terminal device does not need to write the first attribute and a new attribute value of the first attribute in each device node file.
In the above embodiment, different device node files correspond to different fifo buffers in the X-1 device node files corresponding to the first operating system. Therefore, when a certain attribute of the first operating system changes, the first operating system writes the changed attribute into the first-in first-out buffer area, and the operating system corresponding to the first-in first-out buffer area reads the attribute and the attribute value in the first-in first-out buffer area according to the first-in first-out principle, so that the attribute synchronization is realized.
In the above embodiment, when the terminal device writes the first attribute, that is, the attribute whose attribute value changes, in a certain device node file, the writing is performed through a property service (property service). Therefore, when the system property is set in the property service by the Java layer, native (native) layer, setprop command, the property setting (property _ set) in the property service process is called. The method comprises the steps that the content of system attribute synchronization is added into the setting of attribute writing, the terminal device judges whether the attribute of the current operating system needs to be synchronized to other operating systems, if the attribute needs to be synchronized to other operating systems, the terminal device writes the attribute and the attribute value into a device node file created by a kernel space in a key value peer-to-peer mode, and the device node file stores the related information of the attribute needing to be synchronized through a kernel first in first out (kfifo) ring buffer area.
Fig. 3 is a process schematic diagram of an attribute synchronization method according to an embodiment of the present invention. Referring to fig. 3, three operating systems on the terminal device are an operating system a, an operating system B, and an operating system C, respectively, where the operating system C and the kernel space create three domains for the three operating systems: vp1, vp2 and root, vp1 corresponds to 2 kfifo ring buffers, device node file 1 and device node file 2, vp2 corresponds to 2 kfifo ring buffers, namely device node file 3 and device node file 4, and root corresponds to 2 kfifo ring buffers, namely device node file 5 and device node file 6. When the attribute service of the vp1 domain writes the attribute needing synchronization, the terminal device writes the attribute needing synchronization to the 2 kfifo ring buffers corresponding to the vp 1. That is to say, the first operating system of the terminal device writes the attribute to be synchronized into the device node file 1 and the device node file 2 by using a write process, and then, since the device node file 1 and the device node file 2 correspond to the VP2 and the root, respectively, the attribute synchronization process in the VP2 can achieve synchronization between the operating system a and the operating system B by reading the device node file 1; the attribute synchronization process in the root can realize the synchronization of the operating system A and the operating system C by reading the device node file 2.
Fig. 4 is a schematic structural diagram of an attribute synchronization apparatus according to an embodiment of the present invention. The attribute synchronization apparatus according to this embodiment is applied to a terminal device that supports X operating systems, where X is greater than or equal to 2, each operating system in the multiple operating systems corresponds to X-1 device node files in a kernel of the terminal device, and the attribute synchronization apparatus 100 includes:
