Embodiment

Be described in further detail below in conjunction with the enforcement of accompanying drawing technical solution of the present invention.

Figure 1 shows that phone directory data cell structured storage schematic diagram of the present invention.This storage mode is a kind of storage mode that designs in order to guarantee data to be loaded into internal memory fast.Whole phone directory data cell storages hereof.

Each phone directory data unit size is fixed, and comprises whole field informations of phone directory recording.These field informations are stored according to order; The data of each record are stored (being set at the N byte as name field) according to the fixed data field size; The file layout of data cell is consistent with its space layout situation in internal memory.

Figure 2 shows that phone directory data cell access structure array concerns schematic diagram.

On mobile phone screen, data presented unit number is limited, with all numberings of phone directory data cell that satisfy display condition with storage of array, because data unit size fixes, so can obtain the full detail of this data cell according to element number.

First data cell of handset displays screen is corresponding with the current data cell position of data cell access structure array, promptly corresponding with the data cell of data cell access structure array position pointed, the back is the 2nd behind the position indicator pointer in the array, the 3rd successively ....If screen scroll or data variation, position indicator pointer also just moves to correspondence position so.

Figure 3 shows that phone directory data access process.

The first step: the memory headroom that distributes the screen display record.If screen need show N data unit, need to distribute " N so ^*Data unit size " memory headroom.This memory headroom size is fixing, can use repeatedly, is used for loading the phone directory data in the current screen that satisfies display condition.

Also can distribute during storage allocation according to user's needs.For example the user sometimes needs to show 5 numbers, sometimes wants to show 2 numbers, and can change the size of memory headroom this moment.

Second step: phone book applications is according to screening conditions, as querying condition or the sort criteria that is provided with, data presented successively selected.Can display condition (promptly satisfying above-mentioned screening conditions) if n data unit satisfies, the numbering with n data unit is placed in the phone directory data cell access structure array so, otherwise abandons.In the data screening process, because data cell stores according to fixed size, so only need be according to the corresponding data (Data Position+data unit size of screening conditions reading of data unit ^*The data cell numbering, Data Position is meant the first address of storing call notebook data in RAM), check whether satisfy condition, saved the time and the internal memory that load total data.

The 3rd step: the data of the data number correspondence in the phone directory data cell access structure array are loaded in the internal memory.From pointer position, the data cell of the top n data number correspondence of phone directory data cell access structure array is read in the internal memory that the first step distributes, wherein N represents that screen can show N data unit, perhaps represents customer requirements data presented unit number on screen.

The 4th step: data are presented on the mobile phone screen.

The 5th step: when the certificate of showing when the screen digital display changes (screen scroll or drag scroll bar), repeated for the 3rd step.

This step can be loaded into row optimization to data, if the data of screen display change, it is repetitions that but partial data and current screen data are arranged, so only need the data that do not have in the updating memory, simultaneously with the number order of the data based phone directory data cell access structure array in the internal memory, carry out suitable moving, rearrange.Because the size of each data cell is fixed, after number order changes, can calculate the reposition of data cell in internal memory according to numbering, mobil data unit is to new position in internal memory.

The 6th step: if the phone directory screening conditions as application query condition or sort criteria, change, repeated for second step, set up new access structure array.
