Description
Technical Field
The present invention relates to mobile communication technology, and in particular, to a dual-system handover method and apparatus.
Background
Currently, in order to meet the safety requirements of users, dual systems are generally adopted in a safety terminal, wherein one system is used for life, the other system is used for work, and the two systems are highly isolated. When the terminal is started, one system is in the foreground and the other system is in the background. The user can switch the system which is needed to be used at present to the foreground for use through switching among the systems according to the needs. For this reason, it is extremely important for a secure terminal to which a dual system is installed to be able to smoothly and rapidly support a handover between dual systems.
The inventor finds that the existing dual-system switching scheme has the problem of long switching delay in the process of realizing the invention. After careful research and analysis of the existing dual system switching scheme, the inventor finds that the above problems exist specifically as follows:
since there is usually only one set of hardware resources in the secure terminal, the hardware resources in the terminal can only be occupied by one system at a time. The hardware resource using scheme adopted at present is that a foreground system occupies hardware resources and a background system releases the hardware resources.
In the existing dual-system switching scheme, when the system is switched, the use condition of hardware resources of a foreground system needs to be checked, the module which occupies the hardware resources needs to release corresponding hardware resources, and after the release (closing) of all the hardware resources is finished, the switching operation of the system can be continuously finished. Fig. 1 is a schematic flow chart of a conventional dual-system switching method, as shown in fig. 1, where the conventional dual-system switching flow mainly includes the following steps:
and step 1, initiating a system switching process.
And 2, checking the occupation (opening) condition of the hardware resources.
And 3, closing the hardware resources in use, such as Bluetooth (blue), near Field Communication (NFC), GPS and the like.
And step 4, notifying a system switching module of the result.
And 5, the system switching module completes system switching.
In the above-mentioned flow, during switching, it is necessary to check the usage condition of each hardware resource in the terminal one by one and trigger the release of the hardware resource in the on state, and the system switching module needs to wait for the release of all hardware resources to be completed before switching the system. In practical application, if the number of hardware in the on state is large, the time cost generated by the hardware closing link is large, and the time cost of system switching is large, which can reach more than 2s, and under the condition that the foreground system occupies more hardware or certain limit scenes, the switching time can be longer, and reaches about 5s, so that the switching time delay for a long time inevitably influences the user experience, and especially, the switching waiting time delay is more remarkable when the user switches back and forth rapidly.

Detailed Description
The present invention will be described in further detail with reference to the drawings and the embodiments, in order to make the objects, technical solutions and advantages of the present invention more apparent.
Fig. 2 is a flow chart of a method according to an embodiment of the present invention, as shown in fig. 2, a dual-system switching method implemented by this embodiment mainly includes:
step 201, dividing hardware in the terminal equipment into a first hardware set and a second hardware set in advance.
In this step, the hardware in the terminal device needs to be divided, so that only a part of hardware is triggered to be turned off when the system is required to be switched, thereby reducing the time delay of the system switching.
Preferably, in order to greatly reduce the system switching delay, hardware with larger closing delay can be selected to be placed in the second hardware set according to the hardware closing delay, and for the hardware in the set, the hardware does not need to be closed when the system is switched, and the background is triggered to close when the system is required to be used after the system is switched. Specifically, the first hardware set and the second hardware set may be divided by the following method:
the closing time delay of the hardware in the first hardware set is smaller than a preset time delay threshold, and the closing time delay of the hardware in the second hardware set is larger than the time delay threshold.
The time delay threshold can be set to a proper value by a person skilled in the art according to the hardware configuration condition of an actual terminal, so long as the system switching time delay is ensured not to influence the use experience of a user.
In practical application, in order to obtain better user experience, a person skilled in the art may also integrate how often a user opens hardware and how often the hardware is closed, and divide the first hardware set and the second hardware set.
The inventor finds that in the process of implementing the invention, the shutdown of Bluetooth, near field communication, GPS and Wifi generally takes a long time in practical application through simulation. In consideration of the use habit of the user, the influence on the Wifi network connection during system switching is reduced, and preferably, the second hardware set at least comprises bluetooth, near field communication and GPS without considering Wifi.
Step 202, triggering and closing hardware belonging to a preset first hardware set and in an on state in terminal equipment when the terminal equipment detects a system switching instruction; and after the hardware is closed, executing corresponding system switching operation according to the system switching instruction.
In this step, unlike the existing system switching, after receiving the system switching instruction of the user, it is not necessary to wait for the corresponding system switching operation to be performed after all the hardware is released, but only trigger to close the release of part of the hardware (i.e. the hardware in the first hardware set), so as to avoid the occurrence of the situation that the system switching time overhead is large due to the closing of all the hardware.
Step 203, after the system switching operation is completed, for any hardware S2 belonging to the preset second hardware set in the terminal device, when the foreground system needs to use the hardware S2 for the first time, triggering the background system to ensure that the hardware S2 is in a closed state, and when receiving a notification that the hardware S2 is in the closed state from the background system, starting the use of the hardware S2 by the foreground system.
In this step, it is considered that the hardware in the second hardware set does not execute the corresponding resource release operation during the system switching, so after the system switching is completed, when the hardware needs to be used, the hardware is ensured to be in a closed state, so as to ensure that the foreground system can normally use the hardware.
Preferably, the following methods may be used to trigger the background system to ensure that the hardware S2 is in a closed state:
the method comprises the following steps: the foreground system applies for using the hardware S2 to the background system;
the background system inquires whether the hardware S2 is in a closed state according to the application, if so, the foreground system is informed that the hardware S2 is in the closed state, otherwise, after the hardware S2 is closed, the foreground system is informed that the hardware S2 is in the closed state.
The second method is as follows:
preferably, the triggering the background system to ensure that the hardware S2 is in the off state includes:
the foreground system applies for inquiring the switch state of the hardware S2 to the background system;
the background system feeds back the switch state of the hardware S2 in the system to the foreground system according to the application;
if the feedback switch state is the on state, the foreground system informs the background system to close the hardware S2, and the background system closes the hardware S2 and feeds back the closing result to the foreground system according to the notification.
In the method, the first method is to actively close the hardware S2 by the background system according to the application of the foreground system to the hardware S2, and the second method is to send a closing notification to the background system by the foreground system to trigger the background system to close the hardware S2. In practical applications, a person skilled in the art may select an appropriate method according to actual needs, and trigger the background system to close the hardware S2.
Considering that in practical applications, the background system may occupy the hardware with higher priority in the second set, such as bluetooth, NFC, etc., in this case, if the foreground system needs to use the hardware afterwards, the background system needs to be triggered to release the hardware first, so that the hardware can be used normally. In view of the above, in order to improve the reliability of the terminal device, it is preferable that the following method can be further adopted to achieve this object.
After the hardware S2 is used for the first time, if the foreground system needs to use the hardware S2 again, judging whether the current last opening of the hardware S2 is initiated by a background system, if so, after the background system is triggered to ensure that the hardware S2 is in a closed state, opening the use of the hardware S2, otherwise, directly opening the use of the hardware S2.
Preferably, when the foreground system needs to know the on-off state of the hardware in the second set, the foreground system needs to query the on-off state of the foreground system in the background system, so that the foreground system can accurately judge the on-off state of the hardware in the second set, and specifically, the method further includes:
after the system switching operation is finished, when the foreground system needs to inquire the switch state of the hardware S2, triggering the background system to feed back the switch state of the hardware S2 in the background system to the foreground system.
Here, considering that the background system may occupy the hardware with higher priority in the second set, for the hardware in the second set, based on the method, the foreground system may real-time determine the current switching state of the hardware according to the switching state fed back by the background system, and then combine the switching state of the hardware in the foreground system, so that the terminal device may accurately determine the current switching state of the hardware.
