Abstract
In order to avoid deterioration in sound quality caused by band shortage between an HNB-GW and an HNB, in a femto system 100, an HNB-GW 140 is connected to an HNB 120 via a network 130, and relays at least one of transmission and reception of voice data between an MGW 170 and the HNB 120. A narrow band determination unit 150 in the HNB-GW 140 determines whether the band of the network 130 is 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 150, a conversion unit 160 converts the voice data to decrease a bit rate of the voice data transferred to the HNB 120 from the MGW 170.
Claims20
A gateway apparatus connected to a femtocell via a network and relaying at least one of transmission and reception of voice data between a media gateway and the femtocell, the gateway apparatus comprising:
- narrow band determination means for comparing, based on a parameter sent from the femtocell which indicates the location of the femtocell, the location of the femtocell with narrow band location information indicating the location of a narrow band which is registered before initialization in advance in a database, and for determining whether a band of the network is a narrow band by determining whether the band is lower than or equal to a predetermined threshold;
- and
- conversion means for converting the voice data to decrease a bit rate of the voice data transferred to the femtocell via the network from the media gateway when it is determined by the narrow band determination means that the band is a narrow band.
A relay method executing, when relaying at least one of transmission and reception of voice data between a femtocell performing at least one of transmission and reception of voice data with a media gateway via a network and the media gateway, the following processing of:
- comparing, based on a parameter sent from the femtocell which indicates the location of the femtocell, the location of the femtocell with narrow band location information indicating the location of a narrow band which is registered before initialization in advance in a database, determining whether a band of the network is a narrow band by determining whether the band is lower than or equal to a predetermined threshold, and converting the voice data to decrease a bit rate of the voice data transferred to the femtocell via the network from the media gateway when it is determined that the band is a narrow band.
A non-transitory computer readable medium storing a program for causing a computer to execute, when relaying at least one of transmission and reception of voice data between a femtocell performing at least one of transmission and reception of voice data with a media gateway via a network and the media gateway, the following processing of:
- comparing, based on a parameter sent from the femtocell which indicates the location of the femtocell. the location of the femtocell with narrow band location information indicating the location of a narrow band which is registered before initialization in advance in a database, determining whether a band of the network is a narrow band by determining whether the band is lower than or equal to a predetermined threshold, and converting the voice data to decrease a bit rate of the voice data transferred to the femtocell via the network from the media gateway when it is determined that the band is a narrow band.
A femto system, comprising:
- a media gateway;
- a femtocell;
- and a gateway apparatus connected to the femtocell via a network and relaying at least one of transmission and reception of voice data between the media gateway and the femtocell, wherein the gateway apparatus comprises:
- narrow band determination means for comparing, based on a parameter sent from the femtocell which indicates the location of the femtocell, the location of the femtocell with narrow band location information indicating the location of a narrow band which is registered before initialization in advance in a database, and for determining whether a band of the network is a narrow band by determining whether the band is lower than or equal to a predetermined threshold, and conversion means for converting the voice data to decrease a bit rate of the voice data transferred to the femtocell via the network from the media gateway when it is determined by the narrow band determination means that the band is a narrow band.
