ABSTRACT:
An IPv6 address configuration method for a terminal in a wireless mobile network and an apparatus therefor are provided. In the wireless mobile network, an Internet Protocol version 6 (IPv6) address configuration apparatus is provided to a router (access control router; ACR) or a base station (radio access station; RAS). In the address configuration apparatus, a MAC access procedure is performed to extract information required for IPv6 address allocation procedure, and the address is configured by using available fields of a message. In addition, a duplicate address detector (DAD) in which the terminal directly takes part is omitted by using information on the router (ACR) or the base station (RAS). In addition, during the IPv6 address configuration procedure, in order to prevent messages of IPv6 from being transmitted in a wireless region, an agent for address configuration is provided to the terminal. The router (ACR) acquires information required for the address configuration by using a portion of fields of MAC management messages. Accordingly, in the wireless mobile network, it is possible to reduce a time taken for an initial access procedure in which an IPv6 address is allocated to the terminal and to reduce consumption of wireless resource.
