| 20100208617 | METHOD AND SYSTEM FOR REALIZING LOCATION MANAGEMENT OF MULTIHOMED TERMINALS IN UNIVERSAL NETWORK - In Universal Network, there is disclosed a method and system for realizing location management of multihomed terminals, the system comprises home domains and foreign domains, in which the home domains of a multihomed terminal refer to the domains managing the multihomed terminal; the other domains are the foreign domains of the multihomed terminal; each domain includes at least one Identifier Mapping Server and one Accessing-Switching Router; the Identifier Mapping Server memorizes and manages the mapping information; and the Accessing-Switching Router allocates the mapping information for multihomed terminals. This invention facilitates the implement of multihoming in the Internet and makes the network resources be used efficiently. Especially, the Internet service providers can manage the multihomed terminals easily and efficiently. | 08-19-2010 |
| 20100226265 | METHOD OF CONCURRENT MULTIPATH TRANSFER BASED ON RELATIONAL PATHS - A method of Concurrent Multipath Transfer which is based on the relational paths, characterized in that for a packet lost in a path, it allows other packets sent from the path and/or other paths to point out the lost packet through a gap report. According to the present invention, any lost packets and abnormal paths can be found as fast as possible, and can be retransmitted quickly. So this method can avoid the failure of all paths from handing in packets to upper layer only for the abnormity in one path, which limits the speed of whole association. | 09-09-2010 |

| 20080291885 | METHOD FOR COMMUNICATION OF MIPv6 MOBILE NODES - A method for communication of MIPv6 mobile nodes, comprising: the mobile node accesses network at access location and obtains care of address, calculating a privacy identifier PID using the care of address etc. the mobile node replaces its home address by the PID, and sends the PID and the care of address together as binding update message to the home agent and correspondent node, the home agent and correspondent node recover the home address for the mobile node using the PID after they have received the binding update message. The method for communication of MIPv6 mobile nodes according to the present invention uses that a configuring replaced identifier replacing the home address is sent, thereby hiding Ipv6 address. By setting PID and its algorithm, we improve the sequence number in the binding update messages enabling the sequence number has randomness, and prevent the intercepting person continue tracking the mobile node through the home address. | 11-27-2008 |

| 20080249261 | Method of preparing polymethylene-polyphenyl-polyamine - The present invention provides a method of preparing polymethylene-polyphenyl-polyamine (briefly referred to as polyamine, DAM), in which a high gravity rotating bed is used as the mixing reactor of formaldehyde and aniline hydrochloride, the mixing solution of aniline hydrochloride and circulation solution and the formaldehyde are fed into the high gravity rotating bed reactor proportionally to carry out mixing and condensation reaction under a condition of a very high gravity; the materials leaving the high gravity rotating bed reactor is introduced into a stirred vessel to proceed with the pre-condensation reaction and obtain a condensation solution; and the process steps of heating, molecular rearrangement, neutralization, water washing and purification, etc. are completed to obtain the refined DAM. With the method according to the present invention, the main by-products is obviously reduced in the condensation process, the phenomenon of deposit attaching to the inner walls of circulation pipes and heat exchanger and blockage are prevented in the condensation process, the impurity content is low in the refined DAM, and the subsequent product MDI has a lighter color, the product quality is stable and may be improved to a certain extent. | 10-09-2008 |
