ABSTRACT:
With the object of eliminating congestion that has occurred in a station which can not prevent or eliminate the occurrence of congestion autonomously, the SMPP response time in output interfaces21h-21kof a first PPG21are measured and when the time mta, which is m-times of the SMPP response time ta in the normal state, is exceeded, congestion is assumed to occur in an interconnected station of the first PPG21and the response to push transfer request in an input interface21ais delayed. Further, changes in the filling ratio in a buffer memory21bare monitored and when the filling ratio exceeds h %, a decision is made that congestion has occurred in the first PPG21and the response to the push transfer request in the input interface21ais delayed.
