Embodiment
The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
Fig. 1 shows the EMS memory management process that is used for mobile communication equipment terminals according to an embodiment of the invention.
As shown in Figure 1, among the step S110, mobile communication equipment terminals behind software startup, the detection system internal memory upper limit.Figure 2 shows that the concrete steps of Installed System Memory upper limit detection algorithm:
Step S210, the system of judging current mobile communication equipment terminals is fixed memory or Dram, and existing internal memory mostly is Dram, and what generally adopt fixed memory is Nokia S40 system;
Step S220 is judged as fixed memory, directly obtains and return total memory size as the Installed System Memory upper limit;
Step S230 is judged as Dram, then distributes the memory block of fixed memory size to system request, and preferably, the mode by New is the memory block of 2M to the newly-built distribution fixed memory size of system request;
Step S240, if system becomes the distribution of work, execution in step S230, otherwise execution in step S250;
Step S250 returns total memory size as the Installed System Memory upper limit, and total memory size=2M * system becomes the number of times of the distribution of work.
After calculating the Installed System Memory upper limit by Installed System Memory upper limit detection algorithm, execution in step S120;
Step S120 starts the internal memory monitoring device;
Step S130, system enter the monitoring internal storage state;
Step S140, system carry out various operations, comprising: load page, the page show and various user's operation behavior;
Step S150, after system carries out various operations, the detection system internal memory, if the Installed System Memory deficiency, execution in step S160 then, otherwise return step S130, continue the monitoring internal memory;
Step S160, when monitoring low memory, execution in step S130 continued the monitoring internal memory after the execution internal memory reclaimed algorithm;
Concrete internal memory reclaims algorithm as shown in Figure 3:
Step S310, initialization first priority is lowest priority, and execution in step S320;
Mobile communication equipment terminals is provided with corresponding priorities to institute's browsing pages, when the deletion page, sorts from low to high according to this priority, preferentially deletes the low page of priority.
Step S320 carries out internal memory to the first priority corresponding page and reclaims, and execution in step S330;
Step S330 judges whether internal memory satisfies and stops the internal memory recovering condition or first priority is limit priority, if satisfy then return, otherwise execution in step S340;
Concrete, stop the internal memory recovering condition and be: the current Installed System Memory/Installed System Memory upper limit is less than or equal to 80%.
Step S340, first priority increases progressively, execution in step S320.
With the object lesson explanation, the priority of current browsing pages is divided into 3 grades below:
Steps A, initialization first priority is 1 grade,
Step B is that 1 grade the page carries out internal memory and reclaims to priority;
Step C judges whether internal memory satisfies and stops the internal memory recovering condition, if satisfy then return, otherwise execution in step D;
Step D, it is 2 that first priority increases progressively, execution in step E;
Step e is that 2 grades the page carries out internal memory and reclaims to priority;
Step F is judged whether internal memory satisfies and is stopped the internal memory recovering condition, if satisfy then return, otherwise execution in step G;
Step G, it is 3 that first priority increases progressively, execution in step H;
Step H is that 3 grades the page carries out internal memory and reclaims to priority;
Step C judges whether internal memory satisfies and stops the internal memory recovering condition, if satisfy then return, otherwise because it be limit priority that priority has reached 3,3 grades, even therefore fail satisfiedly to stop the internal memory recovering condition, also returns.
Step S320 adopts algorithm as shown in Figure 4:
Step S410 preestablishes a threshold value, execution in step S420;
This threshold value adopts different numerical value according to different mobile communication equipment terminals models;
Step S420 checks whether internal memory reaches the threshold value that S410 sets, if reach then return, otherwise execution in step S430;
Step S430 checks whether internal memory reaches the threshold value that S410 sets after removing the image data of content of pages, if reach then return, otherwise execution in step S440;
Step S440 checks whether internal memory reaches the threshold value that S410 sets after removing the lteral data of content of pages, if reach then return, otherwise execution in step S450;
Step S450 deletion full page also returns.
