摘要:
A hand-over request reception unit receives a hand-over request from a hand-over source base station. When the hand-over request is received, a terminal count acquisition unit obtains the number of terminals each sending a random access signal. A transmission power offset value calculation unit calculates a transmission power offset value of a random access signal to be sent from a terminal performing a hand-over to the base station, in accordance with the number of terminals obtained by the terminal count acquisition unit. A transmission power offset value transmission unit sends the transmission power offset value through the hand-over source base station to the terminal.

A substrate forming mold for forming a substrate by filling a cavity formed between a pair of matching molds 1, 2 with resin, that is, this substrate forming mold has shims 9, 12 disposed at least between a mirror finished surface plate 6 for composing one mold 1 and a stable mold base 8, and in a region inside of a fixed abutting ring 13, depending on fluctuations of plate thickness of formed substrate. As a result, the plate thickness of formed substrate can be adjusted finely, and fluctuations occurring in the radial direction or peripheral direction of the formed substrate can be decreased.
