Estimating the term…
Response time estimation is provided to forecast the response times of a telecommunications device, particularly, a media gateway (206a . . . n). A soft switch (216) switches communication data in a telecommunications network. A call feature server (202) performs call control functions. At least one media gateway (206a) for providing access to telecommunications transmission facilities. A packet manager (204) coupled to both the call feature server (216) and the media gateway (206a) implements message protocol conversion and call flow setup. The packet manager (204) includes a response time estimation module (208) for preventing traffic overload of the media gateway (206a) by the call feature server (202). Message retransmission times for the soft switch (216) are processed by the response time estimation module (208) based on empirical response times from the media gateway (206a) according to a exponential smoothing function. In one aspect, the invention is optimized for use in a telecommunication network and is, for example, set up in the form of an integer-based solution. Further, the invention provides a testing tool for testing a forecast technique.
An apparatus for controlling traffic flow in a telecommunications network according to forecasted response times, the apparatus comprising:
The apparatus of any of the preceding claims, wherein the forecasting module (208) is reset after a predetermined period of time in order to reset a previous overload condition of the media gateway such that a subsequent call is accepted by the media gateway (206a).
The apparatus of any of the preceding claims, wherein the exponential smoothing forecasting for the initial period produces a mean of observed response times.
A method (300) for controlling traffic flow in a telecommunications network according to forecasted response times, the method comprising the steps of:
