Abstract
A method and an apparatus for indicating presence of a transient noise in a call are provided. The method comprises the steps of determining activity at an endpoint of the call by monitoring presence of a signal input from the endpoint into the call and monitoring presence of a potential source of transient noise at the endpoint. Further, based on the activity determination and the monitoring of the presence of a potential source of transient noise, a signal representative of the presence of a transient noise in the call is sent. The present invention is advantageous in that it enables improvement of the quality of the call.
Claims24
A method of indicating presence of transient noise in a call, said method comprising the steps of:
- determining activity at an endpoint of said call by monitoring presence of a signal input from said endpoint into said call;
- monitoring presence of a source of transient noise at said endpoint;
- buffering, for a period of time, determinations associated with the step of determining activity at said endpoint or determinations associated with the step of monitoring presence of a source of transient noise at said endpoint;
- determining that a transient noise is present in the call based on a source of transient noise being detected at said endpoint and an inactive to active transition being detected in said activity;
- updating a state value based on the determination that a transient noise is present in the call, wherein the updating includes adding a first predetermined value to a state value in response to the source of transient noise being detected at said endpoint within said buffering period of time and the inactive to active transition being detected in said activity within said buffering period of time;
- and
- sending a signal representative of the presence of a transient noise in said call, wherein the signal includes information about said state value.
An apparatus for indicating presence of transient noise in a call, said apparatus comprising:
- a processor;
- an activity monitoring unit for determining activity at an endpoint of said call by monitoring presence of a signal input from said endpoint into said call;
- a detecting unit for monitoring presence of a source of transient noise at said endpoint, and determining that a transient noise is present in the call based on a source of transient noise being detected at said endpoint by the detecting unit and an inactive to active transition being detected in said activity by the activity monitoring unit;
- a timer configured to synchronize the operations of the activity monitoring unit and the detecting unit such that determinations of the activity monitoring unit and the detecting unit are made within a predetermined time window;
- and
- a transmitting unit for sending a signal representative of the presence of a transient noise in said call,
- wherein said processor is configured to update a state value based on the detecting unit determining that a transient noise is present in the call, the processor updating the state value by adding a first predetermined value to the state value if the source of transient noise is detected at said endpoint by the detecting unit within said time window and the inactive to active transition is detected in said activity by the activity monitoring unit within said time window, and
- wherein the signal sent by the transmitting unit includes information about said state value.
