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.

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.

Abstract: A method for providing personal information which can overcome the duplication and redundancy of personal information and regional limitation, includes building a Computer Telephony Integration (CTI) information database, a personal information database, and a destination information database in a Service Control Point (SCP), to provide the personal information to CTI destination terminals in an intelligent network; transferring, by a Service Exchange Point (SSP), a calling line identification (CLI) and a dialing number (DN) to the SCP when an originating subscriber dials, retrieving a personal information and a destination information from said databases, and transferring the CLI and the retrieved personal information and destination information to the SSP; and providing, by the SSP, the CLI and the personal information to the destination terminals.

Abstract: A method of processing information charge discount rates for service subscribers in a premium-rate service. Information charge discount rate data for each service subscriber is registered and a service subscriber number and a calling number are received from Service Switching Point. The received service subscriber number is designated as an index value of a main table in a service subscriber database and the main table is then retrieved to check whether data corresponding to the designated index value are present in the main table. If the data corresponding to the designated index value are present, a service feature classification data field in the main table is retrieved to check whether the service subscriber has subscribed to a flexible charging-by-day/time service.
