PURPOSE: A method of automatically driving an application using code analysis is provided to remove complexity and difficulty due to direction selection and execution of a corresponding application, thereby providing convenience in a service. CONSTITUTION: A terminal executes an application for code recognition(S701). The terminal recognizes the code(S702). The terminal requests code analysis to a code analyzing sever(S703). If a corresponding application does not exist in a code analyzing response, the terminal downloads the application(S704,S705). If the application is executed, the terminal requests a service to a corresponding service providing server(S706,S707).

Abstract:
A method and an apparatus for processing plural network addresses in a mobile terminal are provided to enable the mobile terminal to secure mobility using a virtual interface without the modification of existing network modules even in an environment that the mobile terminal has multiple network interfaces and multiple network addresses. A method for processing plural network addresses in a mobile terminal comprises the following steps of: storing combinations of the HoA(Home of Address) of the mobile terminal, plural CoAs(Care of Addresses), and plural NIs(Network Interfaces) which can be connected to plural network(50); selecting an NI combination for connecting an MN(Mobile Node) and a target node in the combinations and setting a corresponding path when the mobile terminal transmits packets to the target node(51); and transmitting the packets through the set path(52).
Abstract:
A method for detecting a movement of a mobile node in a dual stack mobile IPv6 environment is provided to detect a movement to an IPv network by identifying failure of neighbor unreachability detection and RS response. A neighbor unreachability detection process is performed to detect neighbor unreachability detection to a target network of a neighbor when the neighbor is moved(202). An IPv4 address allocation process is performed according to network mobile detection when the neighbor unreachability detection to the target network is not detected(203,204). A router search process is performed(205,207). The mobile detection to an IPv4 network is recognized when the IPv4 address allocation process is performed successfully(206,208,209,213,214,215). The mobile detection to an IPv6 network is recognized when the router search and the IPv6 router search are performed successfully(210-212).
Abstract:
An apparatus and a method for supporting network-based mobility for dual stack terminals are provided to connect data transmitted to a GMAP(Global Mobility Anchor Point) through IPv6(Internet Protocol version 6)-in-IPv4 tunneling or IPv4-in-IPv6 tunneling to an MAP, so that communication with an external terminal can be possible even when the dual stack terminal moves to an another network such as an IPv4-only network or an IPv6-only network. An MAP(Mobility Anchor Point) device(210) for supporting mobility of dual stack terminals comprises a storage(211) and a transmitter(212). The storage stores information about the dual stack terminal after movement and information about an access router to which the dual stack terminal belongs. The information is received from a first MAP(220) as a movement support anchor at another network to which the dual stack terminal has moved. When data to be transmitted to the dual stack terminal is received, the transmitter transmits the data to the first MAP based on the binding information on the dual stack terminal stored in the storage.
Abstract:
A method and an apparatus for allocating MCID(Multicast Connection IDs(Identifications)) for IP(Internet Protocol) multicast packet transmission and transmitting packets using the MCID in a portal Internet network are provided to transmit multicast packets having various scopes and multicast packets of a link local scope in an IEEE 802.16 network by assigning the MCIDs according to a scope of an IP multicast address, thereby removing the necessity of addition MCID assignment even when the number of multicast addresses used on the network is increased, and accordingly providing superior extensibility. A recording medium for recording a data structure of an MCID(Multicast Connection IDs(Identifications))(210) comprises the followings: a CS(Convergence Sublayer) descriptor value which represents a sublayer used for IP(Internet protocol) multicast packet transmission in a portable Internet network; and a scope value which represents a subnet category where the IP multicast packet is transmitted in the portable Internet network. A method for allocating the MCID for IP multicast packet transmission in various categories over the portable Internet network comprises: including the CS descriptor value as one or more bits in the MCID; and including the scope value as one or more bits in the MCID.
