Abstract:
Provided is a method and apparatus for processing a plurality of network addresses in a mobile terminal. The method for processing a plurality of network addresses in the mobile terminal includes: storing combinations of an HoA (home address), a plurality of CoAs (care-of addresses) and a plurality of network interfaces of the mobile terminal, through which the mobile terminal may be connected to a plurality of networks; when the mobile terminal transmits packets to a target node, selecting a network interface combination for connecting the mobile terminal to the target node from among the combinations, and setting a corresponding path; and transmitting the packets through the set path.
Abstract:
Provided is multi-channel and multi-interface mesh router and method of assigning a channel according to a fixed distribution scheme. The channel assignment method may configure a neighbor information table, a parent list, and a dependent list through exchanging of information between mesh routers, and may determine a channel assignment order based on the parent list and the dependent list and then assign a channel, beginning with a mesh router selected as a seed node, and sequentially transmit channel assignment information to mesh routers included in the dependent list.
Abstract:
Provided is a mobile IPv6 fast handovers method, which includes the steps of: a) if a mobile node is moved in a layer 2, receiving a modified RS message from a mobile node in the access router, b) detecting movement of the mobile node in a layer 3 in the access router, c) if the mobile node makes a movement in the layer 3, generating CoA of the mobile node in the access router; d) performing Duplicate Address Detection in the access router to inspect uniqueness of the generated CoA; and e) transmitting a modified RA message to the mobile node in the access router. The Fast Handovers method of the present research performs fast movement detection by using layer 2 information simply and efficiently for fast handover in the mobile IPv6 and generates CoA in the access router instead of the mobile node without operations of many additional messages.

Abstract:
Disclosed is a method of allocating a home network prefix to a mobile terminal having multi interfaces by a local mobility anchor. The local mobility anchor allocates a first home network prefix independently to each of the multiple interfaces for simultaneous access of the multi interfaces. The local mobility anchor allocates a single second home network prefix in common to each of the multi interfaces for inter hand-off between the multiple interfaces. In this manner, a home network prefix for simultaneous access of multi interfaces is separated from a home network prefix for inter hand-off.

Abstract:
Provided is a method and apparatus for forming a superframe in a low-rate wireless personal area network. The structure of an IEEE 802.15.4 superframe is extended to support QoS by increasing the number of GTSs and to minimize waste of a bandwidth through the precise resource reservation although the SO value increases. Thus, since more efficient resource reservation is available compared to an existing IEEE 802.15.4 and the number of GTSs to be assigned is increased to a maximum of 127, simultaneous multiple link connections to more number of devices are available.
Abstract:
A method and system for supporting a seamless handover of a mobile node using a mobile Stream Control Transmission Protocol (mSCTP) to support the mobility of the mobile node are provided. In the method and system, a change in data link layer information, which occurs when the mobile node moves into a new sub-network, is detected and changed data link layer information is transmitted to a network layer. A new Internet protocol (IP) address for the new sub-network is acquired in the network layer using the changed data link layer information. The new IP address is transmitted to a transport layer and dynamic address setting is performed in the transport layer using the mSCTP.
Abstract:
The present invention relates to a composition for the treatment of gout, comprising an Angelica gigas Nakai extract which inhibits xanthine oxidase to reduce uric acid in the blood or urine, thereby being effective in the treatment of gout.Further, the present invention relates to a composition for the prevention of inflammation in gout, comprising an Angelica gigas Nakai extract which has an inhibitory effect on the inflammation-inducing enzyme Cox-2.The Angelica gigas Nakai extract of the present invention is a liquid concentrate consisting of 98% by weight or more of decursin and decursinol angelate as main ingredients, and for administration to human, it is extracted with water and ethanol only as an extraction solvent. In addition, a purification method using a difference in temperature and solubility is used, in order to increase its purity.
Abstract:
Disclosed is a method for multimedia application management using a multi-streaming function of a Stream Control Transmission Protocol (SCTP) and a timed reliability function of a Partial Reliable (PR)-SCTP. The method includes calculating a number of connection objects required for transmitting at least one multimedia information, generating at least one association and stream of the SCTP to correspond to the number of the calculated connection objects, classifying the multimedia information according to purpose, granting a lifetime value to the classified multimedia information; and transmitting, via an SCTP corresponding to the lifetime value from among the SCTPs, the multimedia information to which the lifetime value is granted.
