Embodiment
With reference to figure 1 and Fig. 2, in order to make mobile phone can utilize the mobile phone operating system of the rapid load store of caching mechanism on SIM card, according to the needs that start the operating system the file of mobile phone operating system is divided, but i.e. the present invention is divided into cache file and can not cache file with the mobile phone operating system All Files.During mobile phone load operation system, if load first, then earlier but described cache file is stored in the nonvolatile memory of mobile phone, but and from the cache file of described nonvolatile memory loading mobile phone operating system, from subscriber identification card loading mobile phone operating system can not cache file; If load in the time of follow-up, but then direct cache file from described nonvolatile memory loading mobile phone operating system, from subscriber identification card loading mobile phone operating system can not cache file, but following mask body is to cache file of the present invention with can not describe respectively by cache file.
But 1 cache file
But cache file described in the present embodiment is operation mobile phone operating system or the necessary file of some application programs, when mobile phone loads mobile phone operating system on the SIM card for the first time (for example SIM card is inserted mobile phone for the first time), but mobile phone is saved in described cache file among the nonvolatile storage ROM of mobile phone; During load operation next time system, directly but the nonvolatile storage ROM from mobile phone reads described cache file, rather than read from SIM card by the USB high-speed communication module of mobile phone, so just broken through the restriction of USB transmission rate, the start-up time of having accelerated mobile phone operating system.This shows, but the cache file that is stored on the mobile phone nonvolatile storage ROM is a copy that is stored in the mobile phone operating system (but cache file) on the SIM card, when mobile phone starts the operating system, needs to guarantee the consistency of this two parts file at every turn.
But consistency for the ease of the data of cache file on nonvolatile storage ROM and on high-capacity SIM card of keeping mobile phone operating system, but, but in the present embodiment cache file further can be divided into not modifiable files and frequent revised file according to the read write attribute of cache file.
Modifiable files is not the file that cannot revise in mobile phone operating system startup and the running, image file as operating system, the driving file of mobile phone hardware, and other files that cannot revise, for example application program that cannot be unloaded and library file etc., the characteristics of this class file are after mobile phone operating system (being stored in the SIM card) is issued with card, behind the nonvolatile storage ROM that is saved in mobile phone as buffer memory, under the situation of mobile phone operating system operation, in ROM, do not allow to be modified or to delete; When mobile phone operating system need upgrade, the direct not modifiable files of updated stored on high-capacity SIM card, after mobile phone is restarted, by the not modifiable files of mobile phone operating system up-to-date on the USB high-speed communication module reading SIM card, and the not modifiable files among the new cell-phone nonvolatile storage ROM more.
Not frequent revised file, the chance that this class file is modified in the present embodiment is not high, and be created or deleted, can only be deleted behind the establishment file, can not be modified again, this class file for example with mobile phone operation system start-up operation can be unloaded application program, application program that some are commonly used and the service processes of operating system etc.This class file generally is to install, unload, upgrading under the situation of application program and service module, just can be changed, but so with this class file as the part of cache file when mobile phone loads mobile phone operating system on the SIM card for the first time, can be stored on the nonvolatile storage ROM of mobile phone, can shorten the start-up time of application program, system process effectively.
2, can not cache file
The described file that can not cache file be meant frequent modification is as address list, multimedia audio-video file or other subscriber data files etc.This class file is not that mobile phone operating system loads necessary file, and less demanding to the speed or the real-time of read-write of read-write, gets final product so this class file is stored on the SIM card, does not need to be cached among the nonvolatile storage ROM of mobile phone.
In addition, but but the cache file of cache file that the mobile phone nonvolatile storage is stored in the present embodiment and subscriber identification card storage may be inconsistent, for this reason, when mobile phone load operation system, but but whether the cache file of the mobile phone operating system of storing in the cache file that also needs to judge the mobile phone operating system of storing in the mobile phone nonvolatile memory and the subscriber identification card is consistent, under inconsistent situation, but then from subscriber identification card, upgrade new mobile phone operating system cache file.
During specific implementation, but consistent for the cache file of keeping the operating system on mobile phone nonvolatile storage ROM and the SIM card, but can increase the related information of cache file, but as information such as operating system version number, condition code or sequence numbers with the not modifiable files of association cache file and frequent revised file.Described related information is not limited to version number, condition code and sequence number etc. when reality realizes, as long as but but can distinguish, verify cache file when specific implementation.
Specifically distinguish, during checking, when mobile phone power-on detects nonvolatile storage ROM and has stored the cache file of mobile phone operating system, but mobile phone compares the not modifiable files of the cache file on nonvolatile storage ROM and the SIM card and the frequent pairing related information of revised file respectively, under the inconsistent situation of related information, but the cache file of mobile phone by USB high-speed communication module reading SIM card (for example not modifiable files or frequent revised file), but and the corresponding cache file of new cell-phone nonvolatile storage ROM more, but but promptly keep cache file consistent be to be standard with the cache file that is stored in SIM card, but when therefore upgrading the cache file of SIM card, guarantee atomicity to the SIM card write operation.
Need illustrate, because but the not modifiable files of cache file is the requisite file of mobile phone operating system load operating, closely related with mobile phone operating system, so in above-mentioned specific embodiment, the version number of available handsets operating system comes not modifiable files of association.In version number when the same, but the not modifiable files of expression cache file all is identical, does not need to upgrade, and when version number is different, then needs to upgrade.When mobile phone operating system upgrades, the direct not modifiable files of updated stored on high-capacity SIM card, when mobile phone is restarted, not modifiable files by mobile phone operating system up-to-date on the USB high-speed communication module reading SIM card, then the not modifiable files among the new cell-phone nonvolatile storage ROM more, making not, modifiable files is consistent in the content of two memory stores.
And but the frequent revised file in the cache file is relevant with mobile phone operating system user's operating habit, as installing, unload application program etc.; In a specific embodiment of the present invention, the ICCID of available SIM card (ICCID: the i.e. abbreviation of Integrate circuit card identity integrated circuit card identification code) add the related cacheable not frequent revised file of timestamp, with the not often variation of revised file of identification.Like this, when mobile phone power-on, detect among the mobile phone nonvolatile storage ROM often " the ICCID+ timestamp " of revised file association " ICCID+ timestamp " related with the frequent revised file on the SIM card is not inconsistent the time, then need by the frequent revised file on the USB high-speed communication module reading SIM card, and then upgrade the frequent revised file of nonvolatile storage ROM; When mobile phone operating system in when operation, the not often renewal of revised file as installing, unloading, upgrading application program etc., is the frequent revised file that upgrades SIM card earlier, then the frequent revised file among the nonvolatile storage ROM of new cell-phone more.
Above-mentioned " ICCID+ timestamp " but not frequent a kind of specific implementation of revised file of a kind of association cache file of expression, purpose is to want this class file of unique identification, so will guarantee the uniqueness of timestamp.During specific implementation, can (the survival time refers to the time that begins to calculate from the SIM card hair fastener time to the ICCID of SIM card and survival timestamp, this time can only increase, the zero clearing of can not resetting, to guarantee uniqueness) encode, this unique being coded in when SIM card is upgraded can only increase, and can not reduce.
In addition, for the ease of the not often renewal of revised file, reduce and keep not the often data redundancy of revised file when two storage area data consistencies, to often revised file can also be according to the more fine-grained division of frequency do of file renewal, for example with the operating system service processes that does not often upgrade, the application program of often upgrading commonly used, the frequent games that unloading is installed etc. carefully are divided into different subclass again; The subclass of being divided is used " ICCID+ timestamp+subclass sign " association equally, with the variation of recognin category file.
When mobile phone power-on, the related information of certain subclass of not modifiable files that detects nonvolatile storage ROM and high-capacity SIM card is inconsistent, then by corresponding subclass file in the not frequent revised file on the USB high-speed communication module reading SIM card, then upgrade corresponding subclass file in the not modifiable files of nonvolatile storage ROM, the subclass of two storage areas is consistent; Same, during the mobile phone operating system operation, the not often renewal of the subclass of revised file also is the not frequent subclass of revised file that upgrades SIM card earlier, then the not frequent subclass of revised file among the nonvolatile storage ROM of new cell-phone more again.
By above-mentioned specific embodiment as can be known, but the not modifiable files with cache file in the above-mentioned specific embodiment is subdivided into different subclass again, only upgrade the subclass that changes, but refinement the not often renewal of the file operation of cache file, reduced the read-write of redundant data.
Below with a kind of loading mobile phone operating system of specific embodiment explanation the present invention process.
With reference to figure 3, mobile phone utilizes caching mechanism loading mobile phone operating system to comprise the steps: in the present embodiment
Step 101: mobile phone power-on;
Step 102: whether detection of handset operating system buffer memory, but promptly whether the nonvolatile storage ROM of detection of handset stores the cache file of operating system, if there is not buffer memory, then enters step 103, otherwise enters step 104;
Step 103: but the nonvolatile storage ROM of mobile phone does not have the cache file of storage operating system, mobile phone reads mobile phone operating system on the high-capacity SIM card by USB high-speed communication module, but the cache file of mobile phone operating system is saved in the nonvolatile storage ROM of mobile phone, enters step 107 then;
Step 104: but the nonvolatile storage ROM of mobile phone has stored the cache file of operating system, but the related information of the subclass file by the cache file on relatively nonvolatile storage ROM and the SIM card, but whether the subclass file of judging cache file is consistent on nonvolatile storage ROM and SIM card, if it is inconsistent, then enter step 105, otherwise enter step 106;
Step 105: but during inconsistent on the subclass file of the cache file of the nonvolatile storage ROM of mobile phone storage and the SIM card, but mobile phone is by the subclass file of the cache file of USB high-speed communication module reading SIM card, but upgrade the subclass file of the cache file of nonvolatile storage ROM, to keep the consistency of data, enter step 106 then;
Step 106: finish but judge whether cache file among the nonvolatile storage ROM upgrades, enter step 107, otherwise a step 104, but continue to upgrade the cache file among the nonvolatile storage ROM if upgrade to finish;
Step 107: but the cache file of the operating system among the loading non-volatile memory ROM;
Step 108: the operation mobile phone operating system, the mobile phone power-on process finishes.
But the mobile phone operating system cache file described in the above-mentioned steps specifically is divided into not modifiable files and not frequent revised file, and not frequent revised file can also be subdivided into different subclass in specific embodiment, so when but the nonvolatile storage ROM of mobile phone has stored the cache file of operating system, step 104 is to step 106, relatively, but upgrade the process of the cache file of nonvolatile storage ROM, but be exactly the related information that compares the cache file subclass one by one, but the cyclic process of the subclass of the cache file of renewal nonvolatile storage ROM, but upgrade and to finish (but promptly being consistent) with the cache file of the operating system of memory on high-capacity SIM card up to the cache file of nonvolatile storage ROM, just can be directly from nonvolatile storage ROM loading mobile phone operating system.
In addition, in the running of mobile phone operating system, when installing, unloading application program, during system component, but the frequent revised file of cache file needs to upgrade.Because mobile phone operating system of the present invention is to be standard with the mobile phone operating system that is stored on the SIM card, so but upgrade often during revised file of cache file, the data on the SIM card be upgraded earlier, and the atomicity of SIM card write operation will be guaranteed.Before carrying out the renewal operation, guarantee that the electric weight of mobile phone is enough finished renewal process, cause losing of data to avoid cutting off the power supply.
With reference to figure 4, in the present embodiment to often revised file upgrade specifically and comprise:
Step 201: but determine that the frequent revised file of cache file needs to upgrade, and for example needs to install, unload application program.
Step 202: upgrade the not frequent revised file on the SIM card.
Step 203: after step 202 is upgraded successfully, continue to upgrade the not related information of frequent revised file association on the SIM card, as " ICCID+ timestamp ".(if often revised file carefully is not divided into different subclass, then upgrades not the often associated related information of subclass of revised file, as " ICCID+ timestamp+subclass sign ").
Step 204: but the frequent revised file of the cache file among the new cell-phone nonvolatile storage ROM more.
Step 205: but the not frequent related information of revised file association of the cache file among the new cell-phone nonvolatile storage ROM more; Be different subclass if not frequent revised file is further subdivided, then upgrade not the often associated related information of subclass of revised file, as " ICCID+ timestamp+subclass sign ", the often renewal process of revised file end.
The above only is preferred embodiment of the present invention, and is in order to restriction type of the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
