METHODS OF AND NODES FOR INFORMING A CONTROL NODE IN A SERVING COMMUNICATION NETWORK OF ADDRESS INFORMATION ABOUT A SESSION ANCHOR NODE IN THE SERVING COMMUNICATION NETWORK

摘要

A method of informing a control node in a serving communication network of address information about a session anchor node in the serving communication network is described. The control node is accessible by a terminal via a circuit switched access of the serving communication network. The serving communication network of the terminal is different from an internet protocol based home communication network of the terminal. The method is executed by a session anchor node in the home communication network. The method includes receiving an update request for the control node being updated of address information about the session anchor node in the serving communication network, receiving address information about the session anchor node in the serving communication network, and sending the received address information based on the received update request.
