Method for managing telecommunication terminal telephone directory

Abstract

This invention provides a directory information's attribute management method. It includes: set the safety sign attribute information for telephone directory's information; when it needs to have the information management operation for telephone directory's information, the communication terminal equipment will allow or prohibit the corresponding information management operations according to the stated safety sign attribute information. This invention sets safety attribute for the telephone directory record, it improves relational person record's security and confidentiality in directory; it must have the password verification to change relational person record's attribute, this further improves relational person record's security; it adds separate characters, it makes name field that has confidentiality field show no distortion on the mobile terminal that doesn't support attribute function, this enhances the function's application.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a communication terminal telephone book management method. Background technique [0002] In the communication system, mobile terminals in the GSM system, CDMA system and WCDMA system respectively use subscriber identity modules suitable for the system, namely: Subscriber Identity Module (SIM, Subscriber Identity Module), User Identity Module (UIM, User IdentityModule) , Universal Mobile Telecommunications System Subscriber Identity Module (USIM, Universal Mobile Telecommunications System Subscriber Identity Module), the above-mentioned modules are respectively used to uniquely identify a legal mobile network user in GSM, CDMA and WCDMA networks. [0003] SIM, UIM and USIM not only store the mobile terminal user's network identification information, network service information and network security information, but also store the user's personal information. The most ...

Problems solved by technology

[0005] Since the mobile terminal of a certain mobile terminal user is likely to be out of the user's control range for a certain period of time, for example, the mobile terminal is temporarily lent to other users for use, or the mobile terminal is lost, etc., at this time, the SIM of the mobile terminal , UIM or USIM phone book contact records as important information of mobile terminal users, if no corresponding protection mechanism is provided, it will bring greater losses to mobile terminal users, for example, the user's important phone book information is stolen Wait

[0006] In view of the above problems, at present, mobile terminal users cannot pre-set the corresponding protection mechanism according to the confidentiality requirements of the information in the phone book, therefore, it is impossible to ensure the security and privacy of contact records
