Abstract: An IP(Internet Protocol) address setup method and a device are provided to prevent unnecessary delay from occurring owing to an attempt of an address setup method which is not supported in a new network, thereby executing fast and efficient address setup. Information on an IP address setup method of a new network after handover is obtained through an IS(Information Server)(S100). IP address setup is performed by using the IP address setup method while a mobile node accesses the new network(S110). The information on the IP address setup method of the new network includes information indicating that the IP address setup method used in the new network is one of IPv6(IP version 6) stateless address configuration, IPv6 stateful address configuration, IPv4 static configuration, IPv4 dynamic configuration, and IPv6 manual configuration.

Abstract: A method and an apparatus for setting an Internet protocol address are provided to decrease an address searching delay by setting the IP address based on setting information from an information server. An apparatus for setting an Internet protocol address includes an IP address setting information receiver(110) and an IP(Internet Protocol) address setting unit(120). The IP address setting information receiver acquires IP address setting information of a new network after a handover from an IS(Information Server). The IP address setting unit sets the IP address by using the IP address setting information as a priority, while a mobile terminal is connected to the new network. The IP address setting information contains first and second information. The first information notifies whether the new network uses an IPv6(Internet Protocol version 6) address setting scheme. The second information notifies whether the new network uses a DHCPv6(Dynamic Host Configuration Protocol version 6) address setting scheme.

Abstract: A method of adjusting quality of service (QoS) with respect to changes in a transmission environment of a mobile terminal receiving data based on a stream control transmission protocol (SCTP) session. When the transmission environment of the mobile terminal receiving data based on the SCTP session changes, the mobile terminal transmits link information indicating a new transmission environment to a destination node, and the destination node adjusts the quality of data or the size of a transmission window based on the link information. Thus, without adding separate network devices, the QoS of the data being transmitted can be adjusted with respect to the changed transmission environment, only by adding functions with software to the transmission terminal and the reception terminal. Also, since the destination node manually adjusts the transmission window according to the link information, packet loss can be minimized compared to the conventional congestion control method.
