摘要： If security cannot be ensured between a mobile node and a corresponding node for the communication utilizing Mobile IPv6, communication is exposed to a threat such as tapping of communication content at the moving destination when the mobile node makes the route-optimized communication. In the case where the route-optimized communication is conducted for a communication partner as the communication using the. Mobile IPv6, the mobile node has the automatic setting function to use the IPsec and also has the function to use the tunnel protected by the IPsec between the mobile node and the home agent apparatus when the setting of the IPsec with the communication partner fails.

摘要： It is provided a mobile communication system comprising base stations, call control servers and access gateways. The call control servers cause a mobile terminal accommodated in one of the control server to transmit the location registration request so that the mobile terminal accommodates in another control server according to a processing amount of control signals. The base station selects a second call control server into which the one of the mobile terminals is to be newly accommodated. The one of the call control server switches to a power-saving state after the mobile terminal is accommodated into the another call control server.

摘要： Disclosed herewith is a communication system, which can solve the following conventional problem that if packets exchanged between a terminal and an HA are encapsulated with use of the mobile IPv6 protocol, the PDSN cannot identify any IP flows in the mobile IPv6 tunnel. Consequently, there is no QoS usable appropriately to the services in the EV-D0 RAN. To solve such a problem, the PCRF notifies the HA of the filter information used to specify each IP flow and the flow label assigned to each IP flow. The HA then sets the flow label in the outer IPv6 header of the packet matching with the filter information and transfers the packet to the object unit. The PDSN then refers to the flow label set in the outer IPv6 header to identify the object IP flow in the mobile IPv6 tunnel. Consequently, a proper QoS can be usable for the services respectively in the EV-D0 RAN.

摘要： Mobile terminals have the problem of large packet loss during movement because the mobile terminal has no opportunity to detect movement and generate a new care-of address until a new router advertisement is received, and also cannot register the position in the home agent. The present invention is characterized in including a means to automatically collect network information on access router devices in the vicinity of a particular access router device, and a means to send information in the router advertisement including information on at least one or more adjacent access router devices. The mobile terminal selects an access router device to become the next movement destination, and the most essential characteristic is a means to register the position information beforehand in the home agent.
