Abstract

The invention relates to a positional chat business system based on AGPS (Assisted Global Positioning System), comprising a terminal and a server. The terminal and the server are connected by a GPRS network, and the terminal comprises a chat module which provides a user interface and an AGPS orientation module connected with the chat module and dealing with the AGPS orientation so as to obtain the latitude and longitude of the terminal; the server comprises a chat service module which is used for recording the information of all users and dealing with the information and service request sent by the terminal chat module; an AGPS orientation service module is connected with the chat service module and used for sending an orientation request to the terminal so as to obtain the position of the terminal; a map module is used for providing a specific geographical position of the terminal and sending the position to the chat service module. A user can log on the server through the chat module and obtain the specific position of the user to display on the user interface, thus obtaining the specific geographical positions of the user and friends through the detailed position of the user, which offers more choices and fun to the user.

Description

【Technical field】 [0001] The present invention relates to a chat service system and method, in particular to a location chat service system and method based on AGPS positioning technology that can obtain accurate location information. 【Background technique】 [0002] With the continuous development of mobile communication technology and GPS (Global Position System), AGPS (Assisted Global Position System) technology came into being. Its full name is network-assisted GPS positioning, and it is a combination of network base station information and GPS information for mobile The positioning technology of the station can be used in GSM / GPRS, WCDMA and CDMA2000 networks. The AGPS positioning system accelerates the positioning speed by receiving auxiliary data from the network. [0003] At present, a variety of mobile embedded devices such as smart phones (SmartPhone), handheld computers (PDA), mobile phone versions of handheld computers (PDA Phone) and other multimedia and wireless...
