ABSTRACT:
In a voice communication system1,a gateway server4receives IP packets from the Internet, converts PCM voice data in the IP packets into AMR encoded voice data frames, and transmits to a mobile terminal7.During the propagation to the gateway server4,there is a possibility of loss of IP packets and crucial bit error in IP packets. In that case, the gateway server4puts “No data” data on frames as voice encoded data for the IP packets in question and sends it to the mobile terminal7.The “No data” data is a target of concealment.
