Abstract: A network node comprises a core processing part to perform a core processing function, an ingress processing part to receive incoming signalling messages, an egress processing part to output signalling messages for transmission from the network node, and a message manipulation function to manipulate signalling messages. In a first configuration, the message manipulation function is comprised in the ingress processing part, and in a second configuration the message manipulation function is comprised in the egress processing part. In the first configuration, an egress characteristic is determined, indicative of how an outgoing signalling message is to be outputted, and an incoming signalling message is manipulated based on the egress characteristic. In the second configuration, an ingress characteristic is determined, indicative of how an incoming signalling message has been received, and an outgoing signalling message is manipulated based on the ingress characteristic.

Abstract: In a telecommunications network, a network node processes messages according to different sets of user-programmable message processing rules. The network node includes an input for receiving a series of input messages which are processed in a message manipulation function. Processed messages are also output from the network node according different communication protocols.

Abstract: A network node, during setup of a communication session between a calling party and at least a called party, receives a first provisional response message from a first device comprising first session description protocol (SDP) data; and forwards it on to a calling party device associated with the calling party, the forwarded first provisional response message comprising at least a part of the first SDP data. The network node receives a second provisional response message comprising second SDP data from a second device. Responsive to receipt of the second provisional response message, the network node transmits, during communication session setup, a message to the calling party device which offers to update the SDP data; removes the second SDP data from the second provisional response message; and transmits the second provisional response message from which the second SDP data has been removed to the calling party device.
