Abstract:
PURPOSE: A breast cancer diagnosis apparatus and a method thereof are provided to reduce the unnecessary calculation by accurately detecting the size of breast. CONSTITUTION: A breast(114) is inserted into the free space(113) of a tank(111). A plurality of antennas(116) are arranged in the free space of the tank in order to transmit and receive the electromagnetic wave. A plurality of absorbers(112) are attached to the surface of internal wall of the tank. The absorber absorbs the electromagnetic wave emitted to the outside of the breast among the electromagnetic wave emitted from the antenna. A processor diagnoses the breast cancer by processing the amplitude and phase information of the electromagnetic wave received from the antenna. A plurality of sensors(117) are arranged inside the tank. The sensor gets the spatial information of the breast by sensing the boundary coordinate value of the breast.
Abstract:
PURPOSE: A routing method for securing QoS(Quality of Service) in a wireless communication network is provided to perform routing through an interface securing QoS, when a GPRS(General Packet Radio System) performs packet communication between mobile stations in the wireless communication network. CONSTITUTION: If a T-PDU(Transport-Packet Data Unit) is received(901), a GGSN(Gateway GPRS Support Node) checks whether an incoming address of a packet in the T-PDU is included in a subnet address on a GGSN address table(902). If not, the T-PDU packet is routed through a conventional Gi interface to a wired host(906). And if included, the T-PDU checks a Gii session table to decide whether a preset pre-session exists between preset GGSNs(903). If so, the T-PDU packet is routed and transmitted to the other GGSN through a Gii interface(907). If a preset pre-session does not exist, a session setup procedure between GGSNs is attempted(904). Whether session setup is successful is decided(906). If successful, the T-PDU packet is routed to the other GGSN through the Gii interface(907). And if not successful, the T-PDU packet is routed through the conventional Gi interface(906).
Abstract:
PURPOSE: A method of assigning a dynamic IP address to an Internet service subscriber terminal visiting a 3-generation GPRS(General Packet Radio Service) network and a device thereof are provided to enable a dynamic IP address assignment within a home ISP network through self home ISP network accessing, thereby easily supporting mobility for a mobile ISP network subscriber and supporting a roaming service. CONSTITUTION: A GGSN(Gateway GPRS Support Node)(116) receiving a session generation request transmits an authentication request to an ISP authentication server(405)(S403). The GGSN(116) receiving an authentication message unicast-transmits an IP address request message to a DHCP relay(401)(S407). The DHCP relay(401) relay-transmits the request message to a DHCP server(403)(S411). The DHCP server(403) transmits an IP address supplying message to the DHCP relay(401)(S413). The DHCP relay(401) unicast-transmits the supplying message to the GGSN(116)(S415). The GGSN(116) unicast-transmits an IP address requesting message to the DHCP relay(401)(S417). The DHCP relay(401) relays the requesting message to the DHCP server(403)(S421). The DHCP server(403) transmits an answer message to the DHCP relay(401)(S423). The DHCP relay(401) unicast-transmits the answer message to the GGSN(116)(S425). A mobile ISP subscriber terminal is assigned with an IP address, and forms a session(S427).
Abstract:
PURPOSE: A system and a method for managing an IP address of an ISP(Internet Service Provider) subscriber by using a RADIUS(Remote Authentication Dial-In User Service) server are provided to authorize a subscriber who has moved to a GPRS(General Packet Radio Service) network and allocate a dynamic IP address of a home ISP network. CONSTITUTION: A TE(Terminal Equipment) and an MT(Mobile Terminal) set up a link and perform a PPP(Point-to-Point Protocol) authentication through a PPP connection. Thereafter, the MT transfers a packet data protocol context request generation message from an SGSN(Serving GPRS Support Node), and the SGSN transfers it to a GGSN(Gateway GPRS Support Node). When the SGSN receives a packet data protocol context generation response message from the GGSN, it transfers a packet data protocol context request response message to the MT. When the PDP(Packet Data Protocol) session is completely set up, a mobile ISP subscriber proceeds with authentication and dynamic IP address allocation through connection to the GGSN of the GPRS network or to a RADIUS server or a DHCP(Dynamic Host Configuration Protocol) server of an ISP network. If the RADIUS server performs the authentication, the dynamic IP address allocation and managing function, a RADIUS/DHCP client of the GGSN transfers a RADIUS connection request message to the RADIUS server. Then, the RADIUS server transfers a RADIUS connection permission message to the client. If the RADIUS server and the DHCP server interwork to perform the authentication, the dynamic IP address allocation and managing function, the RADIUS/DHCP client of the GGSN transceives a connection request, a RADIUS authentication and connection permission with the RADIUS sever, and also transceives a DHCP discover, a DHCP offer, a DHCP request and a DHCP ACK message with the DHCP. Thereafter, the GGSN stores the dynamic IP address received from a home ISP network, and configures an NCP(Network Control Protocol)-IPCP(Internet Protocol Control Protocol) configuration-ACK packet and transfers it to the mobile packet terminal.
