Title: compensation method for traffic cut-off
Inventor: CHAE I SIK
Filed: 2001-02-13
Abstract: PURPOSE: A method for compensating a traffic disconnect is provided to supply a compensation with respect to a traffic disconnect properly when a transmission traffic is disconnected by a trouble of a communication channel. CONSTITUTION: A switching center sets a call between a calling side terminal and a receiving side terminal and opens a communication channel according as a call is generated for transmitting information from the calling side terminal(S1-S2). The switching center receives information of a calling traffic length from the calling side terminal(S3). If an information transmission traffic is transmitted continuously from the calling side terminal, the switching center relays traffic(S4-S9). If a transmission traffic is disconnected caused by a decomposition of a call induced by a break of the communication channel(S10), the switching center checks a call decomposition time in accordance with the break of the communication channel and checks an information transmission amount status(S11). The switching center embodies a lottery number to a user of the calling side terminal by referring to the call decomposition time and the information transmission amount status(S12). The lottery number is stored in a database. The switching center requests a transmission of the remaining information(S13). If the remaining information is transmitted from the calling side terminal, the switching center stores the remaining transmission traffic information(S14-S16). If a communication status of the receiving terminal is normal, the switching center reopens the communication channel to the receiving side terminal(S17) and transmits the stored remaining traffic information to the receiving side terminal(S18).
