METHOD FOR DECIDING COMMUNICATION ROUTE IN RADIO SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method for deciding a route between a master unit and a slave unit by which the master unit whose electric field strength in communications viewed from the individual slave units is as strong as possible can be selected as a main route. SOLUTION: One slave unit is extracted from a plurality of slave units which are newly set. A plurality of main candidate master machines are extracted on the basis of the positional data of a plurality of master units (SO4). Data are BC-communicated from the individual master units to the slave units and field strength is measured (SO6). The master unit having the largest field strength is selected from them. When an additional registration is possible, the above master unit is set as the main route master unit. When additional registration is impossible, a station having the next largest field strength is selected and a similar procedure is performed (S08 to S14). The similar procedure is repeated on the other slave units to complete the registration of the main route master station of all the slave units.
