Abstract

PURPOSE: To avoid lowering of the system function even in case a certain using right unit has some fault by providing the by-pass transmission line to the using right transmission line.
CONSTITUTION: The system comprises common resources A, user B of the common resources, using right control unit C and others. In case the using right (code signal) of resources AK is transmitted to Ci from Ci-1(i-1st unit) or Ci-2 and then the using right is transferred to the next unit after the fixed process, Cifirst inquires Ci+1 for the permission of transfer of the using right and transfers the using right to Ci+1 if the permission is given from Ci+1. And no permission is given within a fixed time from Ci+1 in case the using right transmission circuit between CiWCc+1 has some fault or Ci+1 is using a certain resources A1(except for AK). Thus, Ci gives the same inquiry to Ci+2 via the using right by-pass transmission line and transfers the using right to Ci+1 if the permission is given. In such way, the system function can be secured continuously.
