Abstract:
1. A method in a communication network for connecting an application server (AS) of an internet protocol multimedia subsystem (IMS) to an intelligent network (IN) through an interface unit, wherein the IMS comprises a call server control function (CSCF) unit connected to the AS arranged for processing call signaling, wherein the method comprises the following steps with respect to a call: the interface unit directing call signaling to the AS through the CSCF unit; the AS processing the call signaling, thus yielding processed call signaling, and sending the processed call signaling through the CSCF unit back to the interface unit; the interface unit (a) receiving the processed call signaling, and (b) directing the call to a destination based on information received in the processed call signaling, by instructing a service switching point of the IN to route the call over the IN in a case where the call is an intelligent network to intelligent network call; and the interface unit returning the processed call signaling unmodified to the CSCF unit in a case where the call is destined to the IMS.
