The invention relates to a method and a network node for providing a packet-switched network user with a service via the intelligent network. In the packet network, a session is established for routing functionality of packets originating from and terminating at the user when the user registers to the network. To implement the services according to the intelligent network principles, a control record (SR) for the session is added to the packet network node(s) which control record recognises the events which trigger the connection to the intelligent network. Alternatively, the control record can be formed when the user activates the Packet Data Protocol PDP context.
