PROBLEM TO BE SOLVED: To minimize only accesses to a URL causing congestion, without restricting access to URLs independent of congestion. ;SOLUTION: A device 7 periodically collects the usage rate of each CPU of each node (a base station device, a switch, and an IP network connector 4) in A network and number of accesses/min and number of time-outs/min from a device 4 to update a node load information table and a URL access information table (S201 to S204), when the node load information table includes a node, whose threshold is exceeded (S205) and the URL information table includes a URL whose threshold exceeded (S206), the device 7 adds the URL and a restricted number of accesses/min to a restriction URL information table (S207), transmits the restriction URL information to the switch, and when the access to the URL is restricted, the switch updates number of accesses/min to the URL, permits access when it is the restricted number of accesses/min, or rejects the access, when it exceeds the restricted number of accesses/min.;COPYRIGHT: (C)2003,JPO
