Abstract: Provided is a method for a network adaptive error control for selecting an appropriate error control method according to the statue of a network, in transmitting a fax data over the Internet by using a T.38 protocol. The provided method includes receiving a T.38 fax data to recognize errors, transmitting a predetermined statistical information on the T.38 fax data to the media gateway controllers, selecting an error control method by determining the status of a network over which the T.38 fax data is transmitted, based on the statistical information, transmitting the error control method to the gateway that transmits the T.38 fax data, and renewing an existing error control method by receiving the error control method and transmitting the T.38 fax data according to the renewed error control method. According to the provided method, an appropriate error control method can be used according to the status of a network in real time, in transmitting a fax data over the Internet. Therefore, the performance of an error control improves, thereby securing a stable communication and improving a transmission speed. As a result, a communication speed increases so that transmission efficiency improves.

Abstract: Provided are a method for controlling errors of an Internet fax data according to the statue of a network by using a receiver report (RR) message in a real-time transport control protocol (RTCP) and a gateway to which the method is applied. Therefore, transmission errors are reduced and a transmission speed of a fax data is improved in transmitting a fax data over the Internet. The provided method includes receiving a T.38 fax data for analyzing a predetermined QoS motoring data of the T.38 fax data and generating status information, transmitting the status information to a gateway which has transmitted the T.38 fax data, receiving the status information for analyzing a packet loss of the transmitted T.38 fax data based on the status information, and increasing or decreasing a secondary message sequence length based on an analysis result. The provided method can control errors of a T.38 packet in real time, according to the status of a network, in transmitting a T.38 fax data over the Internet. Therefore, the performance of an error control improves, thereby securing a stable communication and improving a transmission speed. As a result, a communication speed increases so that transmission efficiency improves.
