Efficient Transmission of Voice Data Between Voice Gateways in Packet-Switched Networks

摘要

A voice gateway receives packets transmitting voice data between two voice gateways, each received packet includes header data and voice media payload, means for establishing a voice trunk between the two voice gateways based on the header data of the received packets. The voice media payloads of the received packets are extracted and combined into a single packet, the single packet including for a voice call a dedicated channel data of the established voice trunk comprising an identifier of the respective voice call and the voice media payload of the respective voice call. A single set of header data is added to the single packet, the single set of header data includes base information for synchronizing the flow of data between the two voice gateways. The single packet is transmitted to the receiving voice gateway via the voice trunk.

主权项

1. A voice gateway for transmitting voice data to a receiving voice gateway in a packet-switched network by establishing a voice trunk, the voice gateway comprising:
a transceiver configured to receive packets transmitting voice data between the voice gateway and the receiving voice gateway, wherein each received packet comprises header data and voice media payload from one or more voice flows; an interface configured to establish a voice trunk between the voice gateway and the receiving voice gateway based on the header data of the received packets; a processor configured to extract and combine the voice media payloads of the received packets into a single packet, wherein the single packet comprises for a voice call a dedicated channel data of the established voice trunk comprising an identifier of the respective voice call and the voice media payload of the respective voice call; a processor configured to add a single set of header data to the single packet, wherein the single set of header data comprises base information for synchronizing the flow of data between the voice gateway and the receiving voice gateway; and a transceiver configured to transmit the single packet to the receiving voice gateway via the voice trunk.
