Abstract
Systems and methods for improving quality of a call over network (CON) are provided. Call quality may be improved via buffer length modulation based upon the call scenario type. Scenario detection may be based upon who speaks, and the duration of the speaking, as well as contextual analysis. Further, the call over network quality may further be improved by deploying modules over the network. The modules are intermediary vehicles between each communicator and backend servers. The modules intercept audio packets from the communicator to detect packet loss, and perform recovery of lost packets, thereby accelerating real-time audio conversations.

A method for improving quality of a Call-Over-Network (“CON”) conference call by scenario based buffer delays, useful in association with a plurality of callers, each of the callers having a communicator, the method comprising:
- determining a scenario, from a group of options, of the CON using a delay buffer server in a telecommunication network, wherein the group of options includes a presentation, a meeting, and a conversation;
- modulating a delay buffer length in response to the scenario, wherein the delay buffer length is modulated based upon what type of call is occurring as indicated by the scenario;
- and
- providing a delay indication to a caller of the plurality of callers from the communicator if the delay buffer length is at or above 800 ms, wherein the delay indication is a replay of the audio to the caller synchronized to the delay length.
A system for improving quality of a Call-Over-Network (“CON”) conference call by scenario based buffer delays, useful in association with a plurality of callers, each of the callers having a communicator, the system comprising:
- a scenario identifier configured to determine a scenario, from a group of options, of the CON, wherein the group of options includes a presentation, a meeting, and a conversation;
- a processor configured to modulate a delay buffer length in response to the scenario, wherein the delay buffer length is modulated based upon what type of call is occurring as indicated by the scenario;
- and
- a delay indicator configured to provide an indication to a caller of the plurality of callers from the communicator if the delay buffer length is at or above 800 ms, wherein the delay indication is a replay of the audio to the caller synchronized to the delay length.
