INVOKING A SERVICE IN AN INTERLLIGENT NETWORK

摘要

Method and devices for invoking a service in a telecommunications network with a switching node (18) and an intelligent network. The intelligent network has a service 5 control ent it y (16) and a service switching entity (17). The switching node (18) receives a request to set up a call, determines if the call requires invocation of a service in the intelligent network, and if so, instructs the service switching entity (17) and proceeds set up of the call. Proceeding set up of the call is executed before an instruction from the service switching entity (17) is received, allowing continuation of the call set up 10 without introducing any delays. The service control entity (16) and service switching entity (17) perform further functions to support the switching node.
