The invention discloses end-to-end break transferring method based on call control, on the TCP layer based on equal network transmission, the receiver loads the dynamic linking library, and it can realize the end-to-end break transferring via the interface of application program, the steps includes: first the transmitter initializes, starts the main line program of monitoring; when one starts transmitting files or one requires the other to transmit files, it enters the transmitting flow, after the transmitting-receiving sides make agreement, the transmitter starts to transmit file, and the transmitting-receiving sides record the start location and the length of file automatically, if one exit in the transmitting course, and then enters the breaking flow, and the breakpoint file is recorded on the log; next time one side requires the file transmission, then enter the anew transmitting flow, until the file is load completely. The invention solves the problems that scope of application of the break transferring function is single, it has extended scope, the break transferring method can be used in any communication mode in IP network to transmit data to solve the data break problems; it can search and negotiates the data source automatically.
