Abstract
Abstract A communication network having intelligent network functions which collects traffic data for call services without requiring alteration of or addition to programs in all of the service switching nodes in the communication network even if a new call service is introduced as an intelligent network service. For this reason, a service control node (SCN) has a unit assigning a call service identification information (ID) to a new call service and the service switching node provides a registration table receiving the identification information (ID) and registering the same in it. If a call service requested by the calling party is in the registration table, the traffic data is collected for the call service.
