METHOD FOR UPDATING SECTOR LIST OF HOME ZONE DATABASE FOR HOMEZONE SERVICE

摘要

PURPOSE: A method for updating a sector list of a home zone database for home zone service is provided to add the information of a sector, excepted from a sector list due to a low signal strength of pseudo noise, to the sector list. CONSTITUTION: Bins adjacent to a bin including a subscriber are defined so as to exist as one of the following bins; the first bin of which the x coordinates value is a positive and which is located on the x-axis and expressed as coordinates(2x0,0), the second bin which is located on the first quadrant and expressed as coordinates(2x0,2y0), the third bin of which the y coordinates value is a positive and which is located on the y-axis and expressed as coordinates(0,2y0), the fourth bin which is located on the second quadrant and expressed as coordinates(-2x0,2y0), the fifth bin of which the x coordinates value is a negative and which is located on the x-axis and expressed as coordinates(-2x0,0), the sixth bin which is located on the third quadrant and expressed as coordinates(-2x0,-2y0), the seventh bin of which the y coordinates value is a negative and which is located on the y-axis and expressed as coordinates(0,-2y0), and the eighth bin which is located on the fourth quadrant and expressed as coordinates(2x0,-2y0). If the location of the bin comprising the subscriber is located on the x-axis and its x coordinates value is a positive, the first bin is selected to bring sector list information from zone data. If it is located on the first quadrant, the first to the third bin are selected. If it is located on the y-axis and its y coordinates value is a positive, the third bin is selected. If it located on the second quadrant, the third to the fifth bin are selected. If it is located on the x-axis and its x coordinates value is a negative, the fifth bin is selected. If it is located on the third quadrant, the fifth to the seventh bin are selected. If it is located on the y-axis and its y coordinates value is a negative, the seventh bin is selected. If it is located on the fourth quadrant, the seventh bin, the eighth bin and the first bin are selected.
