Document Type and Number:
Japanese Patent JP5102224
Kind Code:
B2
Abstract:
An IP address is assigned to each of IP bearers, and a mobile anchor device (GWN) 33, which serves as an anchor in a mobile communication system, manages association among an identifier of a mobile terminal 7, those IP addresses, and identifiers that identify radio access means. A handover between different radio access networks 1 and 3 is implemented by assigning an IP address already used in a handover source IP bearer to a handover destination IP bearer.
