Abstract
The objective of the invention is to provide a mobile communication control method and mobile communication system in which mobile IPv6 and SIP are integrated by a core network of 3GPP2. In the mobile communication system, the mobile node MN executes a registration procedure for a Care-of-Address acquired in a visited network by the communication between the mobile node and a home agent server HA, executes a registration procedure for the Care-of-Address by the communication between the mobile node and an SIP server, and executes a communication procedure for session establishment by the communication between the mobile node MN and a correspondent node not through the home agent server but through the SIP server.
