Abstract:
A method for dynamically optimizing the transport of a speech signal received from a wireless telephony device through a packet-switched network, said method comprising the steps of:determining at least one Quality of Speech (QoS) transmission characteristic of said packet-switched network intermediate to a first Media Gateway (MGW) and a second MGW coupled to said packet-switched network, the fidelity of speech transmitted through said packet-switched network being a function of said at least one QoS transmission characteristic; dynamically selecting a speech codec as a function of said at least one QoS transmission characteristic of said packet-switched network; encoding said speech signal into speech data using said dynamically-selected speech codec; transmitting said speech data through said packet-switched network from said first MGW to said second MGW; and decoding said speech data at said second MGW using said dynamically-selected speech codec.
