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 method for identify and processing a dynamic IP and a static IP when an ISP mobile subscriber accesses the third generation GPRS(General Packet Radio Service) network is provided to additionally define a flag field for an ISP mobile subscriber's IP in a PPP(Point to Point Protocol) IPCP(Internet Packet Control Protocol) packet in order to indicate whether the IP is dynamic or static and to add an ISP identifier field in order to easily recognize ISP mobile subscriber processing. CONSTITUTION: In an initialization state, a TE(Terminal Equipment) inputs a user ID and a user password, or a secrete key, and attempts packet mobile network access and registration(510,511). After executing LCP/CHAP/IPCP negotiation with an MT(Mobile Terminal)(512), the TE creates a PDP context message on the basis of an end user information element(513), outputs the created PDP context to the network to request the start of a session(514). As a GGSN(Gateway GPRS Support Node) attempts ISP network access(515), an ISP network mobile subscriber's IP is allocated to the GGSN. The GGSN transmits a PDP session response message, including the allocated IP, to the TE through the MT(516). The TE starts packet mobile communication service and Internet service using the allocated IP(517).

PURPOSE: A method for certifying a subscriber in a radio mobile communications net and a method for generating an encoding session key are provided to supply an algorithm generating an early encoding session key for protecting the algorithm certifying a mobile subscriber and sending data. CONSTITUTION: A method for certifying a subscriber in a radio mobile communications net and a method for generating an encoding session key include a few steps. In the first step the random value(20) of 128 bits and the mobile subscriber's secret certifying key of 64 bits are prepared. In the second step the random value(20) of 128 bits is divided by 64 bits and the value is input to each 16 round F function(21,23), a component of a new mobile subscriber certifying algorithm. In the third step the output stream of 64 bits through operation of F function is generated and is prepared as a key of the second part F function(23). In the fourth step the second part F function(23) inputs the random value of 64 bits and the output stream of the 64 bits and generates the output stream of 64 bits. In the fifth step the output stream of the 64 bits of the second part F function(23) is calculated by exclusive-OR(22) of the random value of 64 bits and the bit unit and the value is divided by 32 bits(25,26) and is calculated by exclusive-OR(24) of the bit unit and 32 bits, the final key stream(28) are generated.

PURPOSE: A method for linking mail address information between different letter sort machines and a system for the same are provided to link information obtained from different letter sort machines to apply the information to mail processing task process, thereby reducing mail classification work. CONSTITUTION: A hardware controller(100) obtains mail ID and mail video information from mail. The hardware controller receives partition numbers about the mail ID or mail video information. The mail is loaded on each partition. An address information system(200) generates partition number information. The address information system links mail information on multiple letter sort machines.

Abstract:
A method and a system for processing registered mails are provided to automatically classify/bind the registered mails by issuing and using a barcode including a zip code of a destination place when the registered mail is received. A postal matter transferor(120) periodically transfers the registered mails inputted to a registered mail processing system. An automatic registered mail classifying/binding part(150) detects destination information from the registered mails transferred through the postal matter transferor and generates a registered mail classification control signal based on the detected destination information. A classifier(130) classifies the registered mails transferred through the transferor into each destination place of the registered mails based on the registered mail classification control signal. A registered mail loader(140) separates and stores the classified registered mails by each destination place.
Abstract:
PURPOSE: A data encoding method is provided to encode data efficiently in view of stability such as a data security and a subscriber authentication, to carry out a high speed of operation, and to allow to apply in a radio communication environment. CONSTITUTION: In a data encoding method of a radio communication environment, messages are input, and the messages are divided into two and the divided messages are input to a left block and a right block respectively. A bit stream input to the right block is input to an F function and the left block of the next round. After a bit exclusive OR operation of the bit stream in which the F function is input to the bit stream of the right block and the bit stream input to the left block is carried out, the result values are input to the right block of the next round. After the above operations are carried out repeatedly by a described times, the result values are transposed and the finally encoded stream is output.
