Abstract
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.
