A GPS protocol data server is connected to the GPS receiver through a physical serial port, so as to obtain the GPS protocol data. A service application program is execute on the GPS protocol data server, and provides a service of resolving the GPS protocol data or converting the format thereof through a TCP/IP based multi-thread communication procedure. A virtual serial port driver is used to generate a plurality of virtual serial ports, and each virtual serial port communicates with the service application program through the TCP/IP protocol. Therefore, application devices or application programs respectively communicates with the service application program through the virtual serial ports, thereby obtaining the service of parsing the GPS protocol data provided by the service application program.
