The present invention provides a protein having \u03b11,2-fucosyltransferase activity, a DNA encoding the protein, a recombinant DNA comprising the DNA, a transformant comprising the recombinant DNA, a process for producing the protein having \u03b11,2-fucosyltransferase activity using the transformant, and a process for producing a fucose-containing complex carbohydrate using the transformant. If the data transferred via the first user plane connection satisfies a trigger condition, the apparatus is configured to initiate a handover procedure of transferring the user equipment to a second user plane connection in a second radio access network. The glass ball rests on the dimples concentrically and gaps between the dimples allow gas to pass therethrough between the glass ball and an inside surface of the tubulation.
