Title: Analysis method of service coverage in wireless communication system
Inventor: KIM SEONG WON
IPC: H04W16/00
Filed: 2000-12-13
Abstract: PURPOSE: A method for analysing service coverage for wireless communication system is provided to analyze the position where the service is provided from any base station and service coverage, thereby enhancing the quality of telephone. CONSTITUTION: A measurement device(10) collects measurement data(quality information, coordinate information, time information) about the measuring areas of quality of telephone and provides the collected data to an analyzer(20). A main processor within the measurement device(10) sets the absolute coordinate of the present position received from a GPS receiver as a start position. The main processor calculates a relative distance for moving a terminal or a system body by the direction information and acceleration information provided from the respective direction sensors and accelerator sensors. The main processor traces the coordinate of moved position by adding the calculated relative distance to the moving start position. The main processor receives a parameter of wireless communication signal received by the terminal at the moved position for every second. The analyzer(20) inquires a PN(Pseudo Noise) value within 4Km of radius in an arbitrary record of the measurement data imported from the measurement device(10) and then pictures a line with the inquired PN, thereby capable of analyzing coverage easily. The analyzer can display that each record of the measurement data receives a service from any base station by using a geographical information database(30).
