Abstract
A system for monitoring quality of calls in a network. A server receives information concerning calls which begin or end in a network and at the same time receives measurements of a quality parameter such as bandwidth. This measurement data is provided by a probe, so that the server is able to correlate calls which are placed through the network with the quality of service in the network at that time. When the quality falls below a desired level, the server notifies the customer or the network operator so that appropriate action may be taken.
Claims8
A method of tracking a call quality of a call, comprising:
- receiving, by a processor of a server, a notification of an entry and a termination of the call through a first gateway and a second gateway in a network;
- obtaining, by the processor, a measurement of the call quality of the call within the network, wherein the measurement of the call quality of the call comprises a measurement of a bandwidth, wherein the measurement of the call quality of the call is calculated at a plurality of times and at a plurality of locations in the network via a plurality of packets of the call;
- correlating, by the processor, the entry and the termination of the call with the measurement of the call quality of the call to determine a location of the plurality of locations within the network where the call falls below a predefined call quality, wherein the network comprises a plurality of sub networks that are operated by at least two different companies;
- and
- informing, by the processor, a calling device and a respective company of the at least two different companies operating the location within the network that the call has fallen below the predefined call quality.
A system for tracking a call quality of a call in a network, comprising:
- a quality parameter measuring apparatus for determining the call quality of the call, wherein the measurement of the call quality of the call comprises a measurement of a bandwidth, wherein the measurement of the call quality of the call is calculated at a plurality of times and at a plurality of locations in the network via a plurality of packets of the call;
- a recording apparatus for recording an entry and a termination of the call traversing through a first gateway and a second gateway of the network;
- a server for receiving information from the recording apparatus and the quality parameter measuring apparatus to determine a location of the plurality of locations within the network where the call has fallen below a predefined call quality based upon a correlation between the entry and the termination of the call with the measurement of the call quality of the call, wherein the network comprises a plurality of sub networks that are operated by at least two different companies;
- and
- an alarm system for informing a calling device and a respective company of the at least two different companies operating the location within the network that the call has fallen below the predefined call quality.
