A telephone number compression storage and decompression method and storage system

Abstract

A kind of telephone number compression storage and decompression method and storage system provided by the present invention, the compression step of the telephone number in the mobile terminal includes: A. After converting all the telephone numbers stored in the mobile terminal into complement codes, from small to Sorting, and numbering all the complement codes after sorting; B. Record the phone number with the serial number 1, and compare the complement code with the previous one of the serial number when compressing the rest of the phone numbers, starting from the high digit Compare one by one until the two complement codes have different characters, only keep the different characters and all characters after that, and obtain the compressed codes of each telephone number; C. store the compressed codes of each telephone number. The invention can compress and store the phone number, solve the problem that the mobile terminal with a small memory capacity takes up a lot of space for storing the phone number, and improve the utilization rate of the memory.

Description

technical field [0001] The invention relates to the field of mobile terminals, in particular to a telephone number compression storage and decompression method and storage system. Background technique [0002] The existing phone numbers are stored in the memory of the mobile terminal by characters. For example, the phone number 13515886290 is the character '1', '3', '5', '1', '5', '8', '8 ','6','2','9','0' are stored in the memory; when storing, there is no connection between the number and the number. When storing, if the length of the number is the same, the occupied storage space is also the same of. [0003] Due to the limited storage space in some mobile terminals, just storing the phone number will occupy more space, which will make the utilization rate of the memory lower, and more storage space cannot be reserved to store other firmware, application software, etc. [0004] Therefore, the prior art still needs to be improved and developed.
