US 8,014,396 B2 · Base station apparatus and transmission method thereof

Abstract

A base station apparatus that limits the influx of speech data into a packet channel and that enables the service quality of the packet channel to be prevented from degrading. In this apparatus, a protocol detecting section (301) detects a protocol contained in an IP header of a packet. Based on the protocol, a packet type detecting section (302) detects a type of packet. Based on the type of packet, a delay addition control section (303) determines whether or not to add a delay. Specifically, when the packet is of VoIP, the delay addition control section (303) instructs a switching section (304) to output the packet to a delay adding section (103), and further instructs the delay adding section (103) to add a delay. Meanwhile, when the packet is an IP packet, the delay addition control section (303) instructs the switching section (304) to output the packet to a scheduler (104).

Claims3

Dependent claims

A base station apparatus that transmits a speech packet and a normal packet other than the speech packet on a packet channel, the base station apparatus comprising:

a detecting section that detects a type of a transmission packet;
and
a delay section that adds a transmission delay to the speech packet transmitted on the packet channel to degrade quality of the speech packet when the detected type shows the speech packet, and that does not add a transmission delay to the normal packet transmitted on the packet channel to maintain quality of the normal packet when the detected type shows the normal packet, wherein:
the delay section adds the transmission delay to the speech packet according to a priority of a communication terminal apparatus receiving the speech packet and adds the transmission delay to the speech packet to be received in a communication terminal apparatus to which an amount of data exceeding a reference data amount is sent, the reference data amount being set per the priority.
