CALL BLOCKADE START METHOD

摘要

PROBLEM TO BE SOLVED: To provide a call blockade start method in call reception control in a radio system. SOLUTION: In a method for starting call blockade in response to a pilot fraction as a call quality measurement value in a base station 200 in a radio system, a sampling square integral circuit 202 obtains a power level based on a current time length, a sampling square integral circuit 204 obtains a power level of a pilot based on the current time length and the both the power levels are fed to a 1st averaging element 210. The 1st averaging element 210 decides a mean pilot fraction based on the current time length from both the power levels. The comparator 220 compares the mean pilot fraction and a pilot fraction blockage threshold value and a controller 240 uses a call reception program to start call blockade in response to the case that the mean pilot fraction is smaller than the pilot fracture blockage threshold value. A frame error rate may be used in place of the pilot fraction for a call quality measurement value.
