Abstract: PURPOSE: A fast handover method to the cellular network in the wireless LAN is provided to omit a part of the unnecessary procedure. CONSTITUTION: A transmit unit(510) transmits a service request message to the base station. A receiver(530) receives the tunneling data received in a base station in response to the service request message from the access point from the base station. The service request message comprises an UNA(Unsolicited Neighbor Advertisement) message. In case the received signal strength of the pilot signal is the predetermined threshold or less, the receiver receives the information for the base station from the access point.

Abstract: An apparatus and a method for service continuity between a UMTS(Universal Mobile Telecommunication System) network and a WLAN(Wireless LAN) are provided to offer a seamless service in case a mobile station moves between a 3GPP(Third Generation Partnership Project) network and a non-3GPP network. An apparatus for service continuity between a UMTS network and a WLAN comprises the first node, the second node, and an IWG(InterWorking Gateway)(250). The first node, or an SGSN(Serving GPRS Support Node)(220), takes charge of packet data transfer with a mobile station(100) within service area of the UMTS network. The second node, or a GGSN (Gateway GPRS Support Node)(230), serves as a wireless gateway between the SGSN(220) and a packet data network(400), and allocates the first address to the mobile station(100) through the SGSN(220) for data communication with the packet data network(400). The IWG(250), when the mobile station(100) moves from the UMTS network to the WLAN, establishes tunneling with the GGSN(230) through the packet data network(400), and provides a seamless service to the mobile station(100) by using the first address.

Abstract: A device and a method for negotiating QoS(Quality of Service) are provided to exchange a data packet with an endpoint device of the 3GPP(Third Generation Partnership Projects) packet exchange service network through an efficient QoS negotiation in the 3GPP WLAN(Wireless Local Area Network) interworking system. The first bearer manager manages the first bearer for exchanging the packet with the endpoint device included in the packet exchange service network. The second bearer manager manages the second bearer for exchanging the packet with a terminal device connected to the wireless network. The third bearer manager manages the third bearer for exchanging the packet between the terminal device and the endpoint device. A controller determines accept for the first QoS requested to set the third bearer from the terminal device through the second bearer depending on available resources of the first and second bearer. The third bearer manager sets the third bearer in case that the controller accepts a request of the terminal device for the first QoS.

Abstract: PURPOSE: An on-demand route search method in an Ad-hoc network is provided to enable all the nodes in an Ad-hoc network to rapidly optimize and search for the whole routes of the network by combining the merits of a table management method and an on-demand method. CONSTITUTION: If a route discovery message is received(S301), a mobile node defines a hop count as '1' and a transport flag as 'false'(S302). Then the mobile node judges whether 'pos', the value of an 'address_length' field, is smaller than '0'(S303). In case that 'pos' is smaller than '0', the mobile node judges whether the transport flag is defined as 'true'(S310). If 'pos' is not smaller than '0', the mobile node defines 'dest' as 'address(pos)'(S304) and judges whether the 'dest' address is its own address(S305). In case that the 'dest' address is its own address, the mobile node judges again whether the transport node is true(S310). However, if the 'dest' address is not its own address, the mobile node judges whether a route having a matched pair of£dest,next| exists in its own routing table(S306). If a route having a matched pair of£dest,next| exists, the mobile node compares the hop value of the route with the presently counted 'hop count' value(S307).

Abstract: PURPOSE: An asynchronous address management method for an IMT-2000(International Mobile Telecommunications-2000) mobile communication network is provided to perform a networking using a PPP(Point-to-Point Protocol) between a TE(Terminal Equipment) and an MT(Mobile Terminal) in a PT(Packet Terminal) of the asynchronous IMT-2000 mobile communication network and accommodate a static or dynamic IP(Internet Protocol) system using a mobile IP and a simple IP as a domain. CONSTITUTION: An SM(Session Management) layer receives a packet data protocol generation request for a packet service, and transmits a signal channel setup request message to a PMM(Packet Mobility Management) layer of a PT in case that a signal channel connection is not set up. The PMM layer of the PT requests the connection of an RRC(Radio Resource Control) layer and the Iu connection of an RNC(Radio Network Controller) and a core network, and transmits a subscriber registration request message to the RRC layer for providing a packet data service to an object core network. If the subscriber registration request message is transmitted to the core network from the RRC layer through an SGSN/GGSN(Serving GPRS(General Packet Radio Service) Support Node/Gateway GPRS Support Node), an address management server of the core network transmits a response message of the Iu connection and a subscriber registration result message to the RRC layer and the PMM layer of the PT through the SGSN/GGSN. The PMM layer of the PT transmits a subscriber registration and signal channel connection response message to the SM layer. The SM layer transmits a packet data protocol generation request message to a server of the object core network through the SGSN/GGSN using a packet data protocol address previously received in an MT. The server receives the packet data protocol generation request message, and assigns a subscriber address. In case that the subscriber address is a static address system, the server determines an address of the PT as an address requested by the PT. If the subscriber address is a dynamic address system, the server determines the address of the PT as an address assigned in the address management server. If the address of the PT is determined, the address management server transmits a packet data protocol generation result including the subscriber address to the SM layer. The SM layer transmits the assigned address and the result about a packet service call process requested in the PT to a PPP of the MT.
