Method to assess the quality of a voice communication over packet networks
View Patent ↗The present invention provides a test method which can determine whether a user terminal is capable of supporting a real time connection, such as a computer telephony link, with a network terminal while simultaneously supporting a connection with a WWW server.
1. A method of operating a communications network, the communications network comprising one or more network data stores, one or more network terminals and a plurality of user terminals, the method comprising:
(a) establishing a first communications link between a user terminal and a first network terminal via said communications network;
(b) establishing a test link between the user terminal and a second network terminal via said communications network;
(c) transmitting a test signal over said test link;
(d) measuring the received test signals to determine the capacity of said test link
(e) establishing a communications link between the user terminal and the network terminal via said communications network in accordance with the result of step (d).
2. A method of operating a communications network according to claim 1 wherein the test link established in (b) is a computer telephony link between the user terminal and the network terminal.
3. A method of operating a communications network according to claim 1 , wherein the test signal comprises speech or speech fragments.
4. A method of operating a communications network according to claim 1 , wherein the communications link between the user terminal and the network terminal established in (e) is a computer telephony link.
5. A data carrier containing computer code for loading into a computer for the performance of the method of claim 1 .
