Description

A terminal, system and method for location query among group members

technical field

The present invention relates to wireless communication technology and global positioning technology, more specifically, relates to a position positioning technology among group members.

Background technique

Global Positioning System (Global Positioning System, referred to as GPS) is a new generation of satellite navigation and positioning system developed by the United States in the 1970s and fully completed in 1994. It has all-round real-time three-dimensional navigation and positioning capabilities in sea, land and air. The GPS system can be used not only for surveying and navigation, but also for speed measurement and time measurement. Accurate positioning through the satellite signal received by GPS can know the driving route, position, speed, altitude and other information of the vehicle.

Wireless communication technology is a technology that provides real-time information transmission for communication users through radio waves, so as to achieve smooth individual communication within the guaranteed coverage area. This technical field mainly includes wireless digital transmission technology, router technology, network management and terminal business services.

Fig. 3 shows a flow chart of a method for location query among group members provided by the present invention.

Step S301. The group owner terminal sends the group establishment request information and the group member information to the service center, the group request information includes group identification information, and the group member information includes member identification information;

Step S302. The service center establishes a group according to the received group establishment request information and member information. First, the service center verifies the received group request information and group identification information, and if the verification passes, the group identification and member identification confirmation information is sent to the group owner terminal;

Step S303. Determine whether there is a group owner terminal or a member terminal authorized by the group owner to set the group and group members. The group setting includes the group name, validity period, and location information reporting time; the group member setting has Member name, permission of members to upload files to shared information, permission of members to browse shared information, permission to dynamically monitor location information of group members. If it is set, execute step S304; if not, execute step S306;

Step S304. If step S303 judges that the group owner terminal or the member terminal authorized by the group owner has set the group and group members, then send the set information to the service center. For example, the group owner terminal sets the group name as " Shenzhen Happy Tour", the validity period is "2009.5.1-2009.5.3", the location information reporting time is set to be reported once every minute, the member names are set as "Little A", "Little B", etc., and the setting of Little A, Little B has the permission to upload photos to the shared information, small B has the permission to browse the shared information, small A has the permission to dynamically monitor the location information of group members in real time, etc.;

Step S305. The service center sends setting confirmation information to the group owner terminal or the member terminal authorized by the group owner. If the setting is successful, the screen will display "Setting is successful, accept the setting information"; if there is no authority or the service center is busy or other reasons lead to setting If it fails, the screen will display "Setting failed, do not accept setting information". It should be understood that the above-mentioned embodiment of the words displayed on the screen is only used to explain the present invention, and the present invention is not limited to this embodiment;

Step S306. The terminal of the group member reports the location information to the service center, and the location information includes the group identification information of the group member, member identification information, current time information and location coordinate information. The SIM card number can be used as the identification information of the member, but the present invention is not limited to the SIM card number, for example, according to the setting, the group member terminal reports the location information to the service center every minute;

Step S307. The service center verifies the member and the group to which the member belongs according to the received member identification information. If the verification is passed, the member's location information is updated through the member's identification information, location information and time information, and stored for future use. Group member terminal query, if the verification fails, the member's location information will not be updated and stored;

Step S308. Judging whether there is a group member terminal sending request information for location inquiry of other member terminals to the service center, if yes, then perform step S309; if not, then perform step S303;

Step S309. If it is determined that the first member of the group sends a location information query request of the second member to the service center, the service center will determine the latest location information corresponding to the second member according to the identification information of the second member, and send the second member The location information of the terminal is sent to the first member. In this step, if the service center detects that the time information corresponding to the latest location information of the second member exceeds the preset time, it will issue a corresponding warning, for example, the second member The service center cannot receive the latest location information due to the shutdown of the member terminal or other reasons. The last time the service center received the location information of the second member terminal was at 13:50 on May 1, 2009, and the current query time is May 2009 At 14:30 on the 1st, the preset time is two minutes, that is, the latest location information stored in the service center is the location information 40 minutes ago. If the preset time of two minutes is exceeded, the service center will send "No latest location detected Information" to the first member terminal, or attach the latest location information and its corresponding time information. It should be understood that the above-mentioned embodiment of the words displayed on the screen is only used to explain the present invention, and the present invention is not limited to this embodiment;

Step S310. The microprocessor of the first member terminal matches the received location information of the second member with the map information stored in the memory, converts the received geographical coordinate location information into map location information, and displays it on the screen, More specifically, marks on the map of the second member and the first member may also be displayed, and the distance between them may be displayed.

After completing the query, continue to execute step S303 to start a new cycle.
