Method of transporting compressed speech in packet mode in the core network of public land mobile network infrastructures

摘要

One aspect of the present invention consists in a method of transporting compressed speech in packet mode in the core network of public land mobile network infrastructures over a core network segment including a pair of transcoders equipped to operate in a tandem-free operation mode enabling transportation of compressed speech over said segment, said transcoders being adapted to format the compressed speech in a first format including compressed speech data and uncompressed speech data, in which method, for optimum transport in packet mode over the whole or a portion of said segment, said first format is changed to a second format including only compressed speech data.
