Description

Mobile communication system with group communication function using global satellite positioning device

technical field

The present invention relates to a mobile communication system, in particular to a mobile communication system with group communication function, which is applied in the Global Positioning System (GPS) and used to display the positions of members in the group.

Background technique

With the development of the global satellite positioning system, related satellite positioning devices have been widely used in general public life or commercial purposes (such as mountaineering outings, personal navigation, vehicle navigation and fishery detection); in general, when satellite positioning devices are applied to vehicle navigation systems, they are combined with electronic maps to display the current position of the vehicle on which the driver is riding on the electronic map, and to inform the driver The best driving route from the departure point to the destination is to help the driver to go to the destination smoothly. Therefore, in the current product application, only the position of the vehicle in which the driver is riding is displayed.

However, with the improvement of the quality of life, there are more opportunities to travel by car with relatives and friends. If the accompanying vehicle is separated, generally the only way to communicate with the driver or passenger of the separated vehicle is to use a mobile phone to confirm each other's current location and decide where to go. Rendezvous, this method of using mobile phones to confirm each other's positions is quite inefficient. For example, when the vehicle is separated, if you are not familiar with the local geographical environment, it is generally customary to use road signs or famous scenic spots as the rendezvous location for rendezvous. However, , this method is very easy to cause misunderstandings between the two parties, and even if they are quite familiar with the local geographical environment, there may be misunderstandings between vehicles. In addition, the method of confirming the meeting place by mobile phone often requires waiting for the other party at the meeting place Arrival, this will waste unnecessary time on vehicle driving, and for this phenomenon, if the vehicle navigation system provides users with the ability to see all the vehicles in the same vehicle on the display screen to control the status of the vehicles in the same vehicle and communicate with the other party in real time, It can save the time of poor communication and waiting for each other to improve the quality of recreation.
