Claim:
A method, comprising: configuring an anchor node in a communication network, wherein the configuring comprises: first requesting to initiate a communication session for a first terminal via a communication management node of said communication network, first establishing, at an anchor node, a binding for the first terminal upon request by said communication management node, forwarding said first requesting to initiate from said communication management node based on the established binding towards a second terminal, acknowledging said first requesting to initiate by said second terminal to said communication management node, and second establishing, at said anchor node, a binding for the second terminal upon request by said communication management node; and communicating data in the communication session between the first terminal and the second terminal, wherein the communicating comprises: transmitting the data to be communicated from the first terminal to the anchor node, the anchor node configured to store a table of respective bindings for the terminals, and relaying the data to be communicated from the anchor node towards a filtering node of said network using the configured bindings for the terminals, wherein the said filtering node filters said data to be communicated based on the bindings for said terminals.
