20090037567LINK MANAGEMENT SYSTEM - A technology is disclosed for efficiently managing the peer relationship, and in particular for allowing to discover which of one or more communication links of the network entity is connected to another network entity having the same identifier. According to this technology, for example, the ID Controller (02-05-2009
20090207782AGGREGATION MANAGEMENT SYSTEM, AGGREGATE NODE, AND DEAGGREGATE NODE - A technology for providing an aggregation management system and the like which can quickly and efficiently manage aggregation in a mobile-environment is disclosed. According to the technology, an aggregate node adds mobile status information to signaling messages of end-to-end signaling sessions received from mobile terminals 08-20-2009
20090252174 MESSAGE IDENTIFICATION METHOD AND A RELAY NODE USED BY THE METHOD - A technology providing a message identification method that can accurately identify a message for reserving the resources of a new path when a path change occurs in a network and the like is disclosed. According to the technology, a step of a relay node 10-08-2009
20090268661MOBILE COMMUNICATION TERMINAL APPARATUS, CONTROL METHOD THEREOF, COMMUNICATION SYSTEM, AND ROAMING METHOD THEREOF - A mobile communication terminal apparatus and a control method thereof wherein a smooth handoff can be quickly achieved in a seamless manner during a roaming between data communication networks of different packet exchange systems. A mobile communication terminal apparatus (10-29-2009
20090319774IDENTIFICATION INFORMATION PROTECTION METHOD IN WLAN INTER-WORKING - By introducing a hierarchical encryption scheme and the use of asymmetric cryptography, the critical information in message exchanges is concealed from unauthorized entities. This helps greatly in preventing man-in-the-middle attacks faced by inter-working. In addition, access control is conducted by introducing a network structure having a rule interpreter that is capable of mapping general rules to WLAN specific commands. It obviates the needs for mobile user's home network to understand information about every WLAN it is inter-worked with. A common interface independent of WLAN technologies could be used by the home network for all the WLANs. The above conception provides a solution to the problems of the protection of user identification information and access control in the inter-working of WLAN.12-24-2009
20100002668SERVICE IN WLAN INTER-WORKING, ADDRESS MANAGEMENT SYSTEM, AND METHOD - The present invention provides a solution to the mobile terminal address management in the WLAN inter-working. By using the access control framework, the mobile terminal could obtain the address, and setup the tunnel together with the granting of service access. The management process would be shielded by the inherent encryption and protection of the access control process, and thus does not need extra security setup procedures to be performed. The invention also provides a method for the terminal to obtain address that binds to the session, using a fine grain service authorization procedure. The terminal could maintain multiple addresses when accessing multiple parallel sessions. The address management is also integrated with the policy control mechanisms. The policy control would provide means for the terminal and its home network to configure the WLAN when necessary after an address alternation. QoS, or tunnelling information would be modified and provisioned according to the new status using channels available in the existing policy control procedures. By this, a smooth address transition in the roaming time could be achieved, and QoS interruption could be minimized.01-07-2010
20100135248Mobile Communication Terminal and Communication Device - Disclosed is a technique for reducing delay when a mobile communication terminal starts communication and reducing consumption of a power resource of the mobile communication terminal. An MN (mobile node) (06-03-2010
