Method and system for communicating fixed IP address based voice data in a dynamic IP address based network environment

摘要

A mobile communication device obtains a receiving network voice data packet (containing a receiving network source IP address of an intermediate system, a receiving network destination IP address of the mobile communication device, and a fixed IP address based voice data packet (containing a fixed source IP address of a sending device, a fixed destination IP address of the mobile communication device, and a voice data payload of voice data)) from the intermediate system which has obtained a sending network voice data packet from the sending device over a first dynamic IP address based network, decapsulated the fixed IP address based packet from the sending network packet and encapsulated it into the receiving network voice data packet and provided the receiving network packet over a second dynamic IP address based network. The mobile communication device decapsulates the fixed IP address based packet from the receiving network packet.
