PROBLEM TO BE SOLVED: To conduct a heavy load test through simulation without the use of real machine of a network service processor NSP in the case that a check for communication processing and job processing of the like by a network service support point NSSP of an intelligent network service is conducted by an NSP simulator and to connect to an incoming call by the round robin system while being in direct connection to the NSSP. SOLUTION: A simulator is provided with a DTE management table 31 managing a terminal address capable of being received by a common share memory accessible by both a test means 40 and a communication control means 50 and a VC path management table 32 managing a logic number of a VC path using the receptible terminal equipment address. In the case of the arrival of an incoming call, the control means 50 recognizes a content of the common share memory 30 to set a VC path. In the case of conducting a heavy load test, a transmission interval is obtained based on a transmission text file storing transmission text data and a traffic in a most frequent state and transmission text data in the transmission text file designated by a scenario file prepared in advance are sent at the transmission time interval.
