  • Communication system and method to be performed in a communication system
    Patent number: 7864734
    Abstract: The invention relates to a communication method and system wherein a network element of a roaming user is attachable to a visited first network and may still be served by a serving means of the home network. The network element of the roaming user is able to indicate a preference, e.g. home or local control, when registering or initiating a connection. A network element of the visited network such as proxy means adds information on the indicated preference when sending a message to the home network. The message is preferably sent as a protocol message, in particular a message of the Session Initiation Protocol (SIP).
