specific Embodiment approach

[0093] S901: The user terminal sends a contact location information request to the instant messaging gateway, wherein the contact location information request includes: contact information, such as the contact's instant messaging number and other information.

[0094] S902: After receiving the contact's location information request, the instant messaging gateway sends the request to the authentication module of the instant messaging background system, and the authentication module analyzes the contact's information, and according to the contact's information and the stored The display status information of the contact setting is used to determine which contacts' location information can be provided to the user, and to find out whether the location information of the contact is cached according to the judgment result. For example, online contacts B, C, and D in user A hide their location information from user A, then according to the authentication result of the authentication m...

Abstract

The invention discloses a method and system to acquiring contact man position information for solving the problem of low precision and accuracy of the acquired contact man position in group in the communication system. The method comprises: the instant communication background system receives the contact man position information request, judges whether the contact man position information is in the buffer memory; while the contact man position information is in the buffer memory, the information is sent to the user terminal; while the contact man position information is not in the buffer memory, the instant communication background system sends the contact man position information acquiring request to the positioning system; the communication background system receives the contact man position information from the positioning system and proving it to the user terminal. The scheme provided in the invention improves the precision and accuracy of the acquired contact man position information in the communication system.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and system for acquiring location information of contacts. Background technique [0002] With the rapid development of Internet technology, instant messaging (Instant Messaging, IM) software, a personal communication tool, has also been widely used. Users can use IM software to interact with multimedia instant messaging such as text, voice, and video. The software can obtain the location information of friends. [0003] In the existing IM software, the IP information of the friend's terminal is mainly used to query, thereby obtaining the position information of the friend. However, the positioning method using IP information has low precision and poor accuracy, so it will gradually fail to meet the needs of users. Contents of the invention [0004] In view of this, the embodiments of the present invention provide a method and system for obtaining...
