ABSTRACT:
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.
