Patent ID: 8660591

Claim:
A method for blocking a terminal from receiving incoming communications without turning off the terminal, comprising: setting, by a user, a state of a terminal to be a no-disturbance state, in which the terminal remains in a power-on state, can normally initiate calls and send short messages and cannot receive incoming communications, through a user interface of the terminal; transmitting, by the terminal, a power-off registration message to a network side in response to the setting of the state of the terminal to be the no-disturbance state, and remaining powered on after transmitting the power-off registration message; acquiring, by the network side, the power-off registration message from the terminal, and performing power-off registration, such that if there are communication services in which the terminal is a called party, then the network side returning a calling party a prompt that the terminal has been powered off; if the user makes a telephone call or sends a short message through the terminal in the no-disturbance state, after the user completes making the telephone call or sending the short message, immediately transmitting, by the terminal, the power-off registration message to the network side and remaining powered on after transmitting the power-off registration message; and after the terminal finishes the power-off registration process, forbidding the terminal from sending registration messages to the network side except the power-off registration message.
