  • IP handoff process method and system for connection of internet protocols between mobile agents in heterogeneous network
    Patent number: 8320332
    Abstract: An IP handoff process method and Internet service system are provided. In the IP handoff process method, a registration request message for multiple IP handoff is received from a mobile station having a plurality of Internet protocol (IP) addresses through a currently-moving mobile agent of the mobile station. Then, the registration request for multiple IP handoff is processed according to information included in the received registration request message. A reply message thereof is transmitted according to the result of updating the information to the mobile station through the currently-moving mobile agent. Then, the received registration request message is transmitted to a previous mobile agent of the mobile station before moving and a home agent of the mobile station as it is.

  • IP handoff method in mobile agent platform environment
    Patent number: 8243685
    Abstract: Provided is an Internet protocol (IP) handoff method in a mobile agent platform (MAP). Accordingly, when an IP address of a mobile node (MN) is changed while the MN moves from an MAP to an adjacent MAP, the two MAPs generate border lists so as to share information on the MN, so that it is possible to perform a rapid IP handoff.

  • SYSTEM AND METHOD FOR INTERWORKING BETWEEN MEDIA QUALITY ASSESSMENT AT TERMINAL DEVICE AND QOS CONTROL IN TRANSPORT NETWORK
    Publication number: 20110149775
    Abstract: Provided is a service quality of experience (QoE) predicting and managing system. The service QoE predicting and managing system may include a media quality measurement system (MQMS) to measure a QoE of media, and a quality of service (QoS)/QoE control system (QCS) to measure QoS parameter information, to predict the QoE based on the measured QoS information, to calculate a QoS parameter adjustment value by comparing and analyzing the QoE measured by the MQMS and the predicted QoE, and to transmit the calculated QoS parameter adjustment value to a service quality control system (SCS).

  • METHOD FOR PROVIDING INTERNET PROTOCOL HANDOFF OF MOBILE NODE UNDER MULTIPLE MOBILE AGENT PLATFORM ENVIRONMENT
    Publication number: 20100100639
    Abstract: Provided is a method for providing Internet protocol (IP) handoff of a mobile node (MN) under a multiple mobile agent platform (MAP) environment. In the method, a registration request message for an IP handoff is received from an MN in a network including a plurality of MAPs, and information about the MN is shared with an MAP managing an area in which the MN is located before through a signal packet path. The signal packet path is established separately from a data packet path for transmitting signal packets associated with IP handoff. An IP handoff for the MN is provided based on the shared information. Therefore, a rapid IP handoff is possible since the two MAPs share information about the MN with each other.
