A current differential protection method for a self-adaptive half-wavelength line based on a time-difference method. Since an electrical distance of half-wavelength power transmission is long, after a fault occurs, there is an obvious time difference between the actuation times for protecting starting elements at two sides of a line. According to the principles of wave propagation, the position of a fault point can be determined by means of a difference between the actuation times for protecting the starting elements at the two sides of the line. By means of taking the fault point as a differential point, a current value at the differential point can be obtained according to a long line equation by means of the voltage and current at protection-mounted positions at the two sides of the line, and a differential current is then calculated.

The present invention provides two methods for diverting call. The key point is that call diverting information including a number to be called is transmitted when there is an incoming call or a conversation is being conducted and then a party receiving the call diverting information initiates a call to a terminal to which the number to be called directs, so that the call is diverted. Further, the present invention provides two phone terminals. By virtual of the present invention, it is possible for a user to select any terminal to receive a call, and such selection may be made before or during the phone conversation. Moreover, since it is unnecessary to use exiting call diverting methods, it is possible for the function which otherwise should be implemented at the switch side to be easily implemented on a terminal, and thus the cost of call diverting is saved. The present invention is easy to be deployed. According to the present invention, missing of calls will not occur, and it is easy to accomplish timed calling back. Further, the present invention only relates to terminals to which it is applied, and needs no support from operators.
