Abstract
In order to avoid deterioration in sound quality caused by band shortage between an HNB-GW and an HNB, in a femto system, an HNB-GWis connected to an HNBvia a network, and relays at least one of transmission and reception of voice data between an MGWand the HNB. A narrow band determination unitin the HNB-GWdetermines whether the band of the networkis a narrow band which is equal to or lower than a predetermined threshold. When it is determined that the band is a narrow band by the narrow band determination unit, a conversion unitconverts the voice data to decrease a bit rate of the voice data transferred to the HNBfrom the MGW
