A storage method, identification method and device for a telephone number

Abstract

The invention discloses a storage method, recognition method and device of telephone numbers. The storage method comprises the following steps: acquiring telephone numbers to be stored; classifying the telephone numbers to be stored according to area codes and number lengths of the telephone numbers to be stored; establishing an index table for each class of telephone numbers; and storing each class of telephone numbers with the established index table. Through the technical scheme of the invention, the data volume of the telephone numbers capable of being stored in a terminal can be optimized greatly, the usage amount of the hard-disk space of the terminal can be reduced, and the recognition hit rate of the telephone numbers in the absence of network can be improved; besides, this storage mode does not need to perform decompression, and reverse checking and recognition of the telephone numbers can be performed, so that the memory consumption can be reduced.

Description

technical field [0001] The invention relates to the technical field of telephone numbers, in particular to a method for storing telephone numbers, a method for identifying telephone numbers, a storage device for telephone numbers and an identification device for telephone numbers. Background technique [0002] At present, when a terminal receives an incoming call, it can connect to a server through a network, and then use a search engine or a database query function to query a phone number database on the server to realize phone number query and identification. or [0003] The telephone number database is stored in the terminal, and when an incoming call is received, the telephone number database on the terminal is directly used to realize the query and identification of the incoming telephone number. [0004] However, both of the above two solutions have some disadvantages. The disadvantages of the first solution are: [0005] In the case of no network, it is impossible t...

AI Technical Summary

Problems solved by technology

[0007] The local memory of the terminal is limited, and it is impossible to store a large number of phone number databases, which will take up too much memory and hard disk space. Therefore, only a relatively small amount of phone number data can be stored, so the recognition hit rate is low. In addition, if through general compression method (such as: zip), these numbers must be completely decompressed when the program is started, and then the caller number can be queried and identified, so it still takes up a lot of memory
