Abstract:
The present invention relates to a node and a method for transmitting initiation information related to a SIP-proxy server between an IMS-client stored in a user equipment (UE) and a Gateway GPRS Support Node (GGSN) via a Access Network (AN) and a Tunnelling Termination Gateway (TTG) node in IP core network. The present invention offers smooth transfer between different protocols and Interworking between different networks.
