Patent ID: 7466690

Claim:
A method for restricting the traffic in a packet-oriented connectionless network, comprising: receiving a voice over internet protocol (VoIP) call by a first access network from a first terminal, the access network communicatively coupled to an IP network having a plurality of nodes and to a first control unit; sending a connection setup from the first access network to the first control unit; transmitting a connection setup from the first control unit to a second control unit, the second control unit communicatively coupled a second access network that is communicatively coupled to the IP network and to a second terminal; identifying from the plurality of nodes an ingress node, the identification by the first control unit; transmitting requirements for the VoIP call from the first control unit to the ingress node; checking by the ingress mode that the respective node fulfills the requirements; identifying from the plurality of nodes an egress node, the identification by the second control unit; transmitting requirements for the VoIP call from the second control unit to the egress node; checking by the egress mode that the respective node fulfills the requirements; and establishing the bearer path from the first terminal to the second terminal over the IP network so that a group of data packets flow between the first terminal and the ingress node via the first access network and flow between the second terminal and the egress node via the second access network.
