  • Patent number: 8195165
    Abstract: An apparatus and method for handover in a mobile communication system enables a Mobile Station (MS) to perform a normal handover without performing an unnecessary handover. A Base Station (BS) apparatus capable of preventing an unnecessary handover includes a handover manager. The handover manager receives handover information, including information about at least one cell through which an MS has passed, from a neighbor cell to determine whether the MS has performed an unnecessary handover. If it is determined that the MS has performed an unnecessary handover, the handover manager notifies the occurrence of the unnecessary handover by the MS to the neighbor cell.

  • Patent number: 7994157
    Abstract: Disclosed are a method for dispersing plant sterol for beverage and a plant sterol-dispersed beverage, of which particle size is nanometer-scale in dispersed beverage. The dispersion of plant sterols starts with the admixing of plant sterol to at least one emulsifier selected from the group consisting of sucrose fatty acid ester, sorbitan fatty acid ester and polyglycerine fatty acid ester, followed by melting the admixture by heating at 60 to 200° C. Afterwards, the molten substance is mixed with an aqueous beverage alone or an emulsifier-containing aqueous beverage in state of its own molten type or power type. This resulting mixture is stirred at a high speed to give a dispersion of plant sterols in an aqueous beverage. The beverage is superior in bioavailability, having good mouth feel, transparent aspect and no influence on the characteristic taste, flavor and color of the beverages.
