Abstract: A method and system for modifying and transmitting intelligent-network service data or service parameters in a telecommunication system comprising an intelligent network, a service control point of the intelligent network, a service data point of the intelligent network, a second telecommunication network and means for connecting the intelligent network to the second telecommunication network. The second telecommunication network is connected via a gateway to the service logic of the service control point and/or to the service data point and a service data parameter and/or the service logic of the intelligent network is modified using a protocol supported by the second telecommunication network.

Abstract: Procedure and system for optimizing the route of a telecommunication connection to be set up in a telecommunication system that includes a mobile switching center (MSC), a service switching point (SSP), a service control point (SCP), a gateway (GW), and a subscriber register (HLR). The service switching point is connected to the service control point and the gateway is connected to the service control point and to the subscriber register. The telecommunication connection to be set up is directed via the service switching point to the service control point. A database query is sent from the service control point, via the gateway, to the subscriber register. In response, the subscriber register returns routing information, on the basis of which an optimal route to the mobile switching center under which the B-subscriber is currently located is determined.
