Description
Technical field
The invention belongs to the mobile communication technology field, the method for information such as quickly loading short messages and phone directory during particularly a kind of mobile terminal-opening.
Background technology
MS (Mobile Station, portable terminal) will load short messages stored and telephone directory information in UIM (User Identity Model, the subscriber identification module) card as mobile phone, data card, net book and radio fixed station etc. when starting shooting.In the prior art, portable terminal must load note and the phone directory recording in the UIM card successively one by one when start, and no matter whether the UIM card has record and have how many bar records, all will scan each record slot.Obviously, the efficient of this load mode is very low.Current, owing to be subjected to the restriction of UIM card hardware condition, the UIM card is slow especially to the response speed of the read data order that portable terminal is sent, so the note and the phone directory that load in the UIM card during mobile terminal-opening be a very long process consuming time, and this has greatly influenced testing with body of user.Such as, portable terminal loads 40 notes from the UIM card often needed 20 seconds even the longer time, and therefore for the cellphone subscriber, the user usually can see the signal language of handset displays " reading data, please after a while ... " when start.
In order to improve mobile terminal-opening speed, improve testing of user with body, people have proposed some solutions.Such as, it is that CN 1856138A, name are called the patent of invention of " method that realizes the mobile phone quick turn-on " that Patent Office of the People's Republic of China has once announced notification number on November 1st, 2006.This invention has partly been opened up a free space at the Flash of mobile phone and has been come virtual SIM (Subscriber Identity Module, subscriber identity module) card memory space, the time need information back-up that initialization reads in the Flash of mobile phone start, finish fast to realize opening initialization.This invention can solve the slow-footed problem of mobile phone power-on to a certain extent, but also exists following deficiency:
At first, this method need take portable terminal lot of F lash memory space, and is particularly all the more so when portable terminal will support to store many UIM card notes and telephone directory information.Because it is with high costs to increase the Flash memory space in the portable terminal that is similar to products such as data card, mobile phone, so this method often is subjected to expensive restriction to be difficult to promote in existing product; Secondly, when the user frequently changes the UIM card, because the Flash storage size is limited, this must cause portable terminal Flash memory block not have note and telephone directory information in the UIM card of newly packing into, so can only from the UIM card, load note and phone directory recording again successively one by one, loading procedure is still very slow when therefore starting shooting, and does not reach the effect of quick loading.
As seen, also there is defective in prior art, haves much room for improvement and develops.
Summary of the invention
Technical problem to be solved by this invention is a long problem of mobile terminal-opening time, a kind of method that realizes quickly loading messages during start of mobile terminal is proposed, adopting said method can reach the purpose that shortens the mobile terminal-opening time, improves the user and tests with body.
For solving the problems of the technologies described above, the method of the realization quickly loading messages during start of mobile terminal that the present invention proposes comprises, the priori of describing the memory state of Subscriber Identity Module internal linear fixed type fileinfo is stored in corresponding EF (Element File in the Subscriber Identity Module, constituent instruments) in the file, the memory state of information in this EF file is known in the Subscriber Identity Module by reading described priori in system during start, load for information about selectively in view of the above again, promptly only read the holding tank that has the information record, and do not read the idle holding tank that does not have the information record.
In the said method, described portable terminal can be mobile phone, data card, net book or radio fixed station etc.
In the said method, described Subscriber Identity Module can be the used RUIM card of cdma system or CDMA2000 system (Removable User Identity Module, Removable User Identity Module), also can be the used usim card of WCDMA system (UMTS Subscriber Identity Module, the UMTS subscriber identity module), can also be the used SIM card of gsm system.
In the said method, described linear fixed type fileinfo is meant all information by the fixing stored in file format of linearity, comprises note or/and information such as phone directories.
Further, the corresponding EF file that the priori of describing the memory state of Subscriber Identity Module internal linear fixed type fileinfo is stored in the Subscriber Identity Module can be realized like this: open up a priori memory block in the corresponding EF file in Subscriber Identity Module, and this priori memory block is indicated a field and describes body field two parts from being divided in logic.Wherein, a sign field is used to indicate whether the corresponding EF file in this Subscriber Identity Module is to be moved terminal for the first time to read, and is used to also indicate whether its place holding tank is the priori memory block; Describing the body field is used to indicate each holding tank of this EF file whether to be written into the information record.
Further, in the portable terminal use, if there is fresh information to write Subscriber Identity Module, system upgrades relevant variable and buffer memory in the portable terminal internal memory, and in the portable terminal shutdown process relevant variable value is write in the description body field of described priori memory block.
Further, in the portable terminal shutdown process, the value of a sign field of system described priori memory block is set to particular value, is used to indicate the priori of preserving the information stores situation of describing this document in the corresponding EF file of this Subscriber Identity Module.
Compared with prior art, the present invention is by being provided with the priori memory block in the EF of Subscriber Identity Module file, and the priori that will next time start shooting when loading linear fixed type fileinfo record is kept at this memory block, because these prioris have been described the information record storage condition in the EF file, therefore when portable terminal is started shooting again, the priori of utilization priori memory block stored can realize loading note selectively or/and linear fixed type fileinfo such as phone directory, the meaningless operation of having been done when having avoided prior art to load note and phone directory, really accomplish to shoot the arrow at the target, and then improved loading velocity.
With publication number is that the inventive method of CN 1856138A is compared, frequently change the user under the situation of UIM card, the result of use of the inventive method is not affected, and do not take the Flash memory space of portable terminal preciousness, and only need take a little memory headroom of portable terminal, this memory headroom size is decided because of different UIM cards, usually in the hundreds of byte.
In addition, but the present invention's generalization is good, cost is low, and effect is remarkable, can improve testing with body of user largely.The present invention only needs the quick value-added tax function of linear fixed type fileinfo when the mobile terminal design correlative code can be realized starting shooting, need not to add any hardware and facility, therefore to be applied to mobile terminal cost cheap in the present invention, but generalization is good, and the mobile terminal-opening time can be shortened largely, improve using of user and experience, strengthen product competitiveness.
