Embodiment 1

[0036] Such as figure 1 As shown, a method for compressing call attribution information includes the following steps:

[0037] 1) City information number;

[0038] Number the city information in the attribution information table (Table 1, only part of the attribution information is described in this embodiment), form the city information and its corresponding numbered city number table (Table 2), and replace the attribution with the number The name of the city in the information table (Table 1) forms Table 3;

[0039] The numbering method in this embodiment is: the city information is numbered one by one starting from 1, and the names of nearly 500 cities in China are replaced by numbers.

[0040] Table I

[0041] 1300000 Beijing 1300014 Tianjin 1300021 Shanghai

[0042] 1300001 Changzhou, Jiangsu 1300015 Zibo, Shandong 1300022 Shanghai

[0043] 1300006 Nanjing, Jiangsu 1300016 Yantai, Shandong 1300023 Shanghai

Embodiment 2

[0160] Such as figure 2 As shown, a method for displaying the attribution information of an incoming call, using the data obtained in Embodiment 1 of the above-mentioned method for compressing the attribution information of an incoming call, specifically includes the following steps:

[0161] (1) Obtain the caller number;

[0162] (2) Find the corresponding classification table (the above table six) according to the first 3 digits of the caller number;

[0163] (3) according to the 4th to 7th of incoming call number, look up the index table (above table seven) of described classification table, find the closest number value;

[0164] (4) find the corresponding data item in Table Nine according to the nearest number value, and accumulate or subtract the value of the same city one by one (accumulate or subtract M times at most, the present embodiment is 20 times), until Obtaining the numerical point or numerical interval of the 4th to 7th digits of the incoming call number, a...

Abstract

The invention relates to a caller attribution information compression method and a caller attribution information display method, comprising the following steps: 1) numbering city information; 2) combining the numbers of neighboring cities; 3) filling vacant address and filling vacant number sections in an attribution information table processed by step 2); and 4) classifying the number sections,extracting the first three positions of the number section data in the attribution information table processed by step 3), forming a plurality of classification tables and deleting the data item of number section therein. The invention realizes high compression to messy and complex number attribution information, leads the number attribution database to be capable of being stored in space with less than 100k bytes, thus greatly saving ROM resource of communication equipment, reducing hardware cost, simultaneously considering searching efficiency, leading a low basic frequency processor also tobe capable of searching data fast; the invention can be widely applied to caller identification display and attribution information inquiry and the like of electronic equipment with communication function (such as fixed phones and mobile phones and the like).

Description

technical field [0001] The invention relates to the technical field of call attribution information display, in particular to a method for compressing call attribution information and a method for displaying call attribution information. Background technique [0002] Existing terminals usually have the function of inquiring the attribution of an incoming call. This function mainly obtains the information of the number attribution by accessing the network or reading a local database. The database includes two parts: number data segment information and attribution name information. The statistical value at the end of 2008 was 148,201, with a total size of more than 2.8M bytes, and with the development of mobile communication services, the database is still increasing. [0003] Due to the high cost of network transmission and the lack of real-time performance, local access has become the main way to obtain information. However, due to the complexity of my country's number seg...
