Summary: | An address dynamic assignment system, a relay apparatus, a location manager, an address management apparatus and an address dynamic assignment method for dynamically assigning terminal identification address information for identifying a mobile node with reduced message exchange via the radio section of a wireless network. A mobile node (1) sends a location registration including home address (IPha) information to an access router (2). An address acquisition necessity determination portion (21) of the access router (2) determines whether or not there is a need to acquire the home address (IPha) information to be assigned to the mobile node (1) based on the home address (IPha) information included in the location registration. An address acquisition proxy portion (22) of the access router (2) acquires the home address (IPha) information. A post-address-acquisition location registration portion (23) sends an location update including the acquired home address (IPha) information to an location manager (4). An assigned address notification portion (24) sends back an acknowledgement (LRAck) including the acquired home address (IPha) information to the mobile node (1). |
