Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to an inter-domain mode synchronization method and apparatus for dual system terminals.
Background
Currently, a dual-system terminal of EP720D is divided into three domains, i.e., a VP1 (working area), a VP2 (living area), and a super user authority (root) domain for acquiring a mobile phone, and a user can trigger the terminal to switch between different Virtual Partitions (VPs). After the terminal is started, the terminal can work in different modes according to the needs of the user, for example, in a public network mode or a private network mode. When the mode switching or the terminal reboots, the mode alignment is needed for the bottom layer root domain and the upper layer VP domain (including VP1 and VP2), otherwise, the terminal cannot successfully access the network or the service is unavailable.
The inventor discovers that in the process of implementing the invention: the existing dual-system terminal sometimes has the problems of network access incapability, inconsistent terminal modes before and after restarting and the like after restarting. The specific reason is analyzed as follows:
as shown in fig. 1, in the current EP720D dual system terminal, the method adopted when the pattern alignment is performed between the bottom layer root domain and the upper layer VP domain is as follows: the property parameter property is used to identify which mode is currently adopted by the terminal, and the property has respective storage areas in three areas of VP1, VP2 and root area, that is, each mode stores a property. When a certain domain sets a new property value, other two domains are informed to update the property value to the new property value, so as to realize the synchronization of the property values of all the domains.
Because the property attribute parameters in the method have respective storage areas in the three areas of VP1, VP2, and root, if the current mode type is updated when the dual-system terminal is powered off, and the VP area currently in the foreground fails to synchronize the new property value to the VP area in the background in time, the problem that the terminal modes before and after the terminal is restarted may occur. For example, if the VP domain in the foreground when the dual system terminal is powered off is the working domain, the user just updates the mode, and for some reason, the property value of the living domain in the background may not be updated synchronously. Thus, when the system is shut down, the property value stored in the life domain is still the old property value. When the terminal is started again, according to the existing starting process, the domain started last is a life domain, so that the domain loaded with the property value last is the life domain, after the life domain loads the property value, the life domain notifies other domains of the loaded property value, and the other domains update the property value stored in the domain according to the received property value. Because the property value of the life domain cannot be updated when the terminal is powered off, based on the above-mentioned starting process, after the terminal is powered on again, the old property value is loaded in the life domain, and accordingly, the property values notified to other domains are also old, which results in that the property values of all domains are uniformly restored to the old property values, rather than the mode updated in the working domain when the terminal is powered off, thereby causing the problem that the terminal modes before and after being restarted are inconsistent.
In addition, in practical application, the property value that the root domain needs to be loaded when the terminal is started (for example, when the terminal is in the cluster enhancement mode) can be customized according to the user requirement. When a terminal is started, a bottom layer root domain is started earlier than an upper layer VP domain, sometimes, after the bottom layer root domain is started well, the situation that a current startup scene needs to modify a property value according to a preset starting mode is monitored, meanwhile, an AT (attention) notification Modem (Modem) is issued to modify the current mode, and AT the moment, the upper layer VP domain is not started well, so that the property value modified in the root domain is not synchronized to the upper layer VP domain, after the VP domain is started well, the property value stored in the VP domain before the restart is initialized, and the property value is synchronized to the root domain again, so that the problem that the property values of the VP domain and the root domain are inconsistent with the property value of the Modem is caused, the terminal is not connected to a network, and the service cannot be normally carried out.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below by referring to the accompanying drawings and examples.
FIG. 2 is a schematic flow chart of a method according to an embodiment of the present invention. As shown in fig. 2, the inter-domain mode synchronization method for dual system terminals implemented in this embodiment mainly includes:
Here, in the process of restarting the terminal in this step, if it is determined that the terminal mode needs to be changed when the root domain is started, the new terminal mode is written into the mode identification parameter, and the Modem is triggered to update the mode to the new terminal mode, otherwise, the terminal mode after restarting is set according to the terminal mode of the mode identification parameter saved before restarting. Different from the existing scheme, the mode identification parameter is a parameter that all domains can access together, that is, all domains acquire the currently adopted terminal mode from the parameter, so that it can be ensured that the terminal modes read by all domains are the same, and further, the consistency of the terminal modes before and after restarting can be ensured, the influence of inconsistency of the terminal modes before and after restarting on user experience is effectively avoided, and: and under the condition that the root domain updates the terminal mode when the terminal is started, the terminal mode set in the Modem is inconsistent with the terminal modes set in the root domain and the VP domain after the terminal is started, so that the problem that the dual-system terminal cannot access the network after being restarted can be solved.
In this step, the specific method for determining whether the terminal mode needs to be changed when the root domain is started is the same as the existing scheme, that is, whether the current terminal mode needs to be updated is determined based on a series of conditions such as whether the current sim card is in place and the mode of the terminal before restarting, and the specific method is mastered by a person skilled in the art and is not described herein again.
In practical applications, in order to ensure that the mode identification parameter can store the terminal mode before shutdown after the terminal is shutdown, the mode identification parameter may be stored in a common area of the non-volatile memory.
In this step, after the VP domain is started, the current terminal mode needs to be obtained from the mode identification parameter, and corresponding mode configuration is executed in the VP domain.
Further, in order to ensure the accuracy of the current terminal mode stored in the mode identification parameter during the terminal operation process, after the terminal is started, if the current terminal mode is changed, the VP domain in the foreground stores the changed terminal mode into the mode identification parameter and sends the changed terminal mode to the root domain; and the root domain executes corresponding mode configuration in the local domain according to the changed terminal mode, and triggers a Modem to set the current terminal mode as the changed terminal mode.
Further, when the VP domain in the foreground is changed, the changed VP domain in the foreground performs corresponding mode configuration in the local domain according to the terminal mode currently acquired from the mode identification parameter.
Here, when the VP domain in the foreground is changed, the VP domain in the foreground directly obtains the terminal mode from the current mode identification parameter. Since the latest terminal mode is always stored in the mode identification parameter, when the VP domain is changed, the VP domain in the foreground acquires the terminal mode from the mode identification parameter, and performs corresponding mode configuration in the VP domain of the foreground based on the terminal mode, thereby ensuring that the currently-used mode of the terminal is consistent with the terminal mode before the VP domain is changed.
The specific method for performing the mode configuration in the VP domain in the foreground in the above method is the same as the existing scheme, and is not described herein again.
Preferably, in order to enhance the user experience, the VP domain may display the current terminal mode in the user interface.
According to the method embodiment, the mode identification parameter shared by all the domains is introduced, the current terminal mode is stored by using the parameter, and mode alignment of different domains is effectively realized. As shown in fig. 3, all fields will read the terminal mode from the mode identification parameter (i.e., oeminfo _ nv in the figure) stored in the common area and write the current terminal mode into the mode identification parameter.
Corresponding to the above method embodiment, the present application further provides an inter-domain mode synchronization apparatus for a dual system terminal, including: a processor to:
when the terminal is restarted, when a root domain is started, whether the current terminal mode is changed or not is judged, if yes, a corresponding new terminal mode is stored into a preset mode identification parameter, a Modem is triggered to set the current terminal mode as the new terminal mode, and the mode identification parameter is used for indicating the current terminal mode; otherwise, the terminal mode indicated by the current mode identification parameter is taken as the current terminal mode; and after the upper layer VP domain is started, performing corresponding mode configuration in the VP domain according to the terminal mode currently obtained from the mode identification parameter.
Preferably, the processor is further configured to:
after the terminal is started, if the current terminal mode is changed, the changed terminal mode is stored in the mode identification parameter in the VP domain of the foreground, and the changed terminal mode is sent to the root domain, so that the root domain informs a Modem to set the current terminal mode as the changed terminal mode according to the changed terminal mode, and executes corresponding mode configuration in the root domain.
Preferably, the processor is further configured to:
and when the VP domain in the foreground is changed, executing corresponding mode configuration in the changed VP domain in the foreground according to the terminal mode currently obtained from the mode identification parameter.
Furthermore, the present application also provides a non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to perform the steps of the inter-domain mode synchronization method of the dual system terminal as described above.
Further, the present application provides an electronic device comprising the non-volatile computer-readable storage medium as described above, and the processor having access to the non-volatile computer-readable storage medium.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
