摘要： An apparatus and method are provided for changing network interfaces in a multiaccess mobile terminal in a wireless communication system including a server for providing high-capacity data transmission service to a mobile terminal, and the terminal for receiving data from the server and supporting various network interfaces. Upon detecting handoff based on current air information received, an interface module reports a change in interface to a new air interface to an upper layer, and manages the mobile terminal such that traffic is transmitted to the new air interface. Upon receiving information on the new air interface from the interface module, a service module determines a bandwidth of the new air interface, generates a message based on the determined bandwidth, and transmits the generated message.

摘要： When a terminal moves from a WLAN network to a cellular network after being allocated an IP address from a PDSN of the cellular network, a tightly coupled interworking method and apparatus between the cellular network and the WLAN network set up a temporary tunnel between the PDSN and an AGW of the WLAN network, and after completion of the handoff from the WLAN network to the cellular network, inform the PDSN of the handoff completion from the terminal, thereby enabling fast seamless handoff without data loss. Compared with the conventional tightly coupled scheme, the proposed tightly coupled scheme can prevent the need for processing cellular signals in the WLAN network because there is no need to transmit cellular signals in a WLAN interval, especially between the terminal and the AGW.

摘要： A handoff method is provided between a mobile communication network including a packet data service node (PDSN), connected to a base station system (BSS), for supporting an Internet protocol (IP) routing function, and a wireless local area network (LAN) including an access router (AR) supporting the IP routing function. Upon detecting handoff to the wireless LAN, an access terminal (AT) with a contact set up to the PDSN exchanges a data packet with a correspondent node (CN) via a tunnel between the AR and the PDSN. The AT determines a user traffic state according to a transmission/reception state of the data packet, and changes the contact connected to the AT according to the user traffic state.

摘要： A method and system for authenticating in a wireless communication system. The system includes a Mobile Terminal (MT), an authenticator, and an Authentication, Authorization, Accounting (AAA) server. When the authenticator requests NAI information for authentication, the MT adds an authentication code to the NAI, and sends a response message including the NAI information to the authenticator. The authenticator relays the NAI to which the authentication code is added, to the AAA server. The AAA server extracts the authentication code from the NAI information, verifies the authentication of the MT, generates a new authentication key, and transmits the new authentication key to the authenticator.

摘要： A method for supporting an idle mode handover of an Single Radio Mobile Station (SR MS) by a target Access Service Network GateWay (ASN_GW) in a heterogeneous wireless communication system is disclosed. The method includes, upon detecting that an operation mode of the SR MS is to be changed from an idle mode to an active mode, acquiring an address of a Home Agent (HA) of the SR MS from a preregistered ASN_GW with which the SR MS has performed a preregistration operation, upon detecting that a Base Station (BS) is to set up a path with the preregistered ASN_GW, transmitting a message, including the address of the HA and requesting to set the target ASN_GW as a new Foreign Agent (FA) of the SR MS, to the preregistered ASN_GW, and upon receiving a message, requesting to register the target ASN_GW as the new FA of the SR MS, from the preregistered ASN_GW, setting up a data path with the HA, and then registering the target ASN_GW as the new FA of the SR MS.

摘要： The present invention relates to a subscriber station security-related parameter negotiation method in a wireless portable Internet system. The subscriber station security-related parameter negotiation method includes security-related parameters in transmitting/receiving basic capability negotiation request messages and basic capability negotiation response messages such that the subscriber station and the base station negotiate the subscriber station security-related parameters. The security-related parameters include an authorization policy support subfield used to negotiate an authorization policy between the subscriber station and the base station, and message authentication code mode subfields used to negotiate a message authentication code mode. The base station can inform the subscriber station that authentication or message authentication is not performed and is omitted according to a service provider policy by writing it on the authorization policy support subfield or message authentication code mode subfield. In addition, the subscriber station and the base station can select an authorization policy formed with at least one combination through the authorization policy support subfield of the security negotiation parameters. According to the present invention, the service provider of the wireless portable Internet system can more efficiently and flexibly manage the system by providing a scheme for omitting an authentication function and a message authentication function as well as for supporting various authorization policies and message authentication functions.
