Method and device for realizing directory service

Abstract

The invention relates to a method and a device for realizing a directory service. The method comprises the following steps of: acquiring mapping information of a name item and a number item in a first record when monitoring that a group indicating bit value of the first record stored in an application directory is a set group identifier; and mapping and storing the mapping information of the name item and the number item in the first record into a name item and a number item in a second record of a basic directory respectively. The device comprises an acquisition module and a mapping module capable of realizing the steps. The method and the device ensure that part of record in the application directory can be mapped in the basic directory so as to make the record read in a terminal directory. The method and the device can realize caller identification on the basis of a function of caller identification of a terminal, ensure the advantages in aspects of storage capacity and format of the application directory, realize the function of the caller identification of the application directory, improve service performance and improve user experience.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method and device for implementing directory services. Background technique [0002] With the development of communication technology and the increase of user demand, the value-added services based on Universal Subscriber Identity Module (hereinafter referred to as: USIM) / Subscriber Identity Module (hereinafter referred to as: SIM) are constantly enriched, super Directory and Enterprise Directory is one of them. [0003] In order to make up for the lack of storage capacity in the terminal directory, a basic directory is set in the existing USIM / SIM card, and the contact information is stored in the specified file "EF ADN (FID=6F3A)". However, the storage space of the basic directory is still limited, generally only 255 records can be stored, and the storage format of the basic directory limits the amount of information. Each record can only store a name and a corresponding ph...

AI Technical Summary

Problems solved by technology

When copying records, the limited storage space of the terminal address book obviously cannot meet the copying requirements, and in the process of copying, since the record format of the application address book is not exactly the same as that of the terminal address book, it may be caused by format conversion problems. A large amount of information is lost, and the adaptation problem of different formats also needs to be solved in the copying program. Considering that different types of terminals have different recording formats, different format conversion algorithms need to be designed, which increases the difficulty of program development

Or there may be a problem that some terminals do not support the copy function

Based on the above reasons, the existing technology has not been able to solve the problem that the application directory supports the caller ID function on the premise of ensuring the advantages of the application directory itself, which brings a certain degree of inconvenience and confusion to users, and affects business performance and users. experience, which hinders the promotion of business

Especially as a new business, the application of the directory may give users a bad impression and it is difficult to promote
