Embodiment Construction

[0023] The implementation of the technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] figure 1 Shown is a schematic diagram of structured storage of phonebook data units in the present invention. This storage method is a storage method designed to ensure that data can be quickly loaded into memory. All phonebook data units are stored in files.

[0025] Each phonebook data unit has a fixed size and contains all field information of the phonebook record. The field information is stored in order; the data of each record is stored according to the fixed data field size (for example, the name field is set to N bytes); the storage form of the data unit is consistent with its spatial layout in the memory.

[0026] figure 2 Shown is a schematic diagram of the array relationship of the phonebook data unit access structure.

[0027] On the mobile phone screen, the number of data units display...

Abstract

The invention provides an optimized phonebook data access method of a mobile phone, comprising the following steps: (a) data units are defined, each data unit has fixed size and is corresponding to a number, and phonebook data is stored in the data units; (b) when in access of the phonebook data, an access structure array is established, the screening of the data units is carried out according to the screening conditions, the numbers of the selected data units are saved in the access structure array, that is, the data of the access structure array is the numbers of the data units; and (c) the phonebook data of the data units which are corresponding to the numbers that meet the display conditions in the access structure array is loaded in a memory for display. Compared with the prior art, as the method adopts the technical measures of the structured storage data units plus the construction of a data unit cheat sheet, the high-speed, convenient and effective phonebook access under the environment of no larger storage space or memory can be realized.

Description

technical field [0001] The invention relates to a method for improving the data access speed of a phone book on a mobile phone. Background technique [0002] The phone book is one of the basic applications of the mobile phone. At present, the data volume of the phone book application of the mobile phone is increasing, and the stored information is also increasing. The speed of the phone book is increasingly used as an important indicator of the ease of use of mobile phones, which is directly related to the experience of mobile phone users. [0003] At present, when the amount of data in the phone book of a mobile phone is very large, the access speed is not very ideal. In order to improve the access speed of the phonebook, a large amount of memory is required. Since the memory resources of the mobile phone system are limited, this method does not work very well. Therefore, it is necessary to provide a convenient and effective method to improve the data access speed of the ...
