Abstract
The present invention provides a kind of method for scheduling task, device and mobile terminal.Methods described includes：Record situation of the user using application；Data are used using history of the situation statistics of application with each nonsystematic task of user mutual during user uses application according to the user；Data are used according to the history, calculate the new prominence score value of each nonsystematic task, prominence score value is smaller, and the nonsystematic task is more important；When Installed System Memory deficiency, according to the new prominence score value of each nonsystematic task, by the nonsystematic task termination that new prominence score value is maximum.Compared with prior art, the present invention can be when being scheduled to nonsystematic task, the task service condition of comprehensive statistics user, the prominence score value of task is more accurately calculated, terminated by mistake in Installed System Memory deficiency so as to be effectively prevented from important task.
Description
Technical field
The present invention relates to system management technologies field, more particularly to a kind of method for scheduling task, device and mobile terminal.
Background technology
When existing embedded system is scheduled middle Installed System Memory deficiency to nonsystematic task, system is interior in order to reclaim
Deposit, the process terminated, the high process of prominence score value can be determined according to the prominence score value of process importance analysis
Importance is low, can be terminated first.When prominence score value is identical, system can press in prominence score value identical process
Come terminated task or process according to the size of committed memory, terminate committed memory maximum task or process first.But actual feelings
In condition, the prominence score value highest of most of background process and identical, system is come eventually by score value and committed memory size
Only task, the larger background system of the internal memory that is commonly used of user is often terminated first.
For example, the running background of system has N number of task, respectively task 1, task 2 ..., task N, their weight
The property wanted score value is identical, it is assumed that wherein task 1 is wechat, be the most-often used program of user but simultaneously the task take
Internal memory is maximum, then in Installed System Memory deficiency, Installed System Memory recycling module first can terminate task 1.But to user and
Speech, other N-1 tasks are all not frequently used, and unessential task, what user was more desirable to be terminated is other N-1
Individual task rather than task 1.
During the present invention is realized, inventor has found following technical problem in the prior art at least be present：
When being scheduled in current embedded system to nonsystematic task, a task can not be synthetically evaluated to user
Importance, task important for a user may be caused to be terminated when system load is excessive by Installed System Memory recycling module,
And resource is taken to the unessential task long-term existence of user, system resource is unable to reasonable distribution.
