    摘要： An apparatus and method for reduction of a handover interruption time using an estimated handover time negotiation in a broadband wireless communication system are provided. A method for supporting a handover of a mobile station in a serving base station includes receiving a handover pre-notification response message including a residual estimated handover time from a target base station, determining a current residual estimated handover time using the residual estimated handover time, and exchanging the determined residual estimated handover time with the target base station.

    摘要： Group handover method and apparatus in a broadband wireless communication system which supports a mobile relay station are provided. A method of a serving base station for group handover of the mobile relay station includes when receiving a measurement report message from a relay station, determining whether the relay station is a mobile relay station of a simple type which forwards a signal; collecting handover related information of the mobile relay station and mobile terminals belonging to the mobile relay station, from pre-stored information; requesting handover of the mobile relay station and the mobile terminals by transmitting the collected handover related information to a target base station; and receiving a message indicating whether the handover of the mobile relay station and the mobile terminals is approved, from the target base station.

    摘要： Provided are a seamless service method controlled by a user terminal, the method including: storing radio access technology (RAT) information and service flow information associated with a connecting radio access network (RAN); when a new link is detected, storing RAT information associated with the new link; verifying whether a new RAN satisfying a handover initiation criterion exists; when the new RAN exists, attempting a link connection with the new RAN; being assigned with an Internet Protocol (IP) to be used in the new RAN; setting up a handover service flow using the new RAN; and receiving a service via multiple paths using a connecting service flow and the handover service flow. Through this, it is possible to provide the seamless QoS even while the handover is being performed.

    摘要： A process for the selective oxidation of olefins to epoxides comprising the step of contacting the olefin (propylene or ethylene) with an oxidant (hydrogen peroxide) in the presence of a Lewis acid oxidation catalyst (MTO), organic base (pyridine or its N-oxide), in a solvent system comprising an organic water-miscible solvent (methanol). The system is pressurized using either the olefin itself or by adding an inert pressurizing gas (nitrogen) to increase the pressure between 230 and 700 psi at a temperature between 0.7 and 1.3 times the critical temperature of the olefin. The resulting increased solubility of the olefin in the organic solvent system increases the selectivity and yield of the desired epoxide (propylene oxide or ethylene oxide).
