Abstract: A tunneling method of a mobile terminal for supporting IP(Internet Protocol) mobility is provided to implement tunneling of the terminal by conducting a packet processing function on a device driver end(network driver end) when a mobile IP is used to support the IP mobility of the terminal mounted with a closed-source OS(Operating System) of an IP end. In case of movement detection(401), a mobile terminal decides whether a network where the mobile terminal is currently located is a home network or a visiting network(402). In case of the home network, the mobile terminal confirms whether an IP layer of a device currently connected to the home network is activated(403). If so, the mobile terminal transmits/receives packets by operating without an additional operation. In case of the visiting network, the mobile terminal inactivates an IP of a home device(406), and transmits/receives the packets(404).

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 enable an IWG(InterWorking Gateway), interworking with the SGSN(Serving GPRS Support Node) or GGSN(Gateway GPRS Support Node) of a 3GPP(Third Generation Partnership Project) network, to seamlessly provide a service to a mobile station in case the mobile station moves from the 3GPP network to a non-3GPP network or returns to the 3GPP network from the 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(250). The first node, or an SGSN(220), executes packet data transfer with a mobile station(100) within service area of the UMTS network. The second node, or a GGSN(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, receives the first address, allocated to the mobile station(100), through the first interface from the GGSN (230) and provides a seamless service to the mobile station(100) by using the first address. Also the IWG(250) forms a tunnel with the mobile station(100) by using the first address.

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.

Abstract: PURPOSE: A method of allocating, releasing and changing an international WLL user identity is provided so that a user can directly request a subscription center to allocate, release and change an international WLL user identity during operation. CONSTITUTION: A method of allocating, releasing and changing an international WLL user identity includes the following steps. A user connects a call to a subscription center in the first step. The subscription center makes inquiry about a user's request by voice in the second step. The user responds to the inquiry of the subscription center by a DTMF(Dual Tone Multiplexed Frequency) tone in the third step. With respect to the user's request generated by communication between the user and the subscription center, the subscription center allocates, releases and changes an international WLL user identity in the fourth step.

Abstract: PURPOSE: A method for analyzing CAI(Common Air Interface) signal messages is provided to store signal messages with bit units transmitted on wireless channels, and to extract the messages as information factors of corresponding fields in accordance with each message type. CONSTITUTION: A CDMA mobile communication system opens an input and an output file, and confirms whether an end of the input file is generated. If not, the system reads a locking header from the input file. The system reads a message of a corresponding channel with a byte length subtracting the locking header size from a length field, according to a code value of the locking header. The system sequentially extracts information factors with byte units from a message body having a bit type, until a final field on the basis of field sequences and sizes of the information factors, according to message types. The system stores an extracted value with the message types and the field information in the output file. If the end of the input file is generated, the system closes an open file to complete the process. If the end of the input file is not generated, the system progresses to the step of reading the message of the channel to repeat the process.
Abstract translation: 目的：提供一种用于分析CAI（Common Air Interface）信号消息的方法，用于存储在无线信道上发送的位单元的信号消息，并根据每种消息类型将消息提取为相应字段的信息因子。 构成：CDMA移动通信系统打开输入和输出文件，并确认是否生成输入文件的结尾。 如果没有，则系统从输入文件读取锁定头。 根据锁定头的代码值，系统从长度字段读取字节长度减去锁定头大小的相应通道的消息。 根据消息类型，系统从具有位类型的消息体中顺序地提取具有字节单元的信息因子，直到基于信息因子的字段序列和大小的最终字段。 系统将提取的值与消息类型和字段信息存储在输出文件中。 如果生成输入文件的末尾，系统将关闭一个打开的文件以完成该过程。 如果没有生成输入文件的末尾，则系统进入读取通道的消息以重复该过程的步骤。
