A control switching method, applied in a first control terminal from which control is to be switched, in a second control terminal to which control is to be switched, and in a server, comprising: sending (S11), by the second control terminal, a request for controlling a controlled device to the server, wherein the server, after receiving the request, requests a first control terminal, which controls the controlled device at present, to transfer control; during a process of controlling a controlled device, receiving (S21), by the first control terminal, a request, sent by the server, for transferring control of the controlled device, wherein the request for transferring control of the controlled device is sent by the server after the server receives a request, sent by a second control terminal, for controlling the controlled device; sending (S22) to the server, by the first control terminal, a notification of agreeing to transfer control, so that the server notifies the second control terminal to establish a communication connection with the controlled device; and sending (S23) to the controlled device, by the first control terminal, an instruction of connecting with the second control terminal, so that the controlled device, after receiving the instruction, establishes a communication connection with the second control terminal and receives a control instruction sent by the second control terminal, receiving (S12), by the second control terminal, a notification, sent by the server, of authorizing to control the controlled device, wherein the notification is sent after the server determines that the first control terminal agrees to transfer control; and connecting (S13), by the second control terminal, communicatively with the controlled device to control the controlled device. sending (S11), by the second control terminal, a request for controlling a controlled device to the server, wherein the server, after receiving the request, requests a first control terminal, which controls the controlled device at present, to transfer control; during a process of controlling a controlled device, receiving (S21), by the first control terminal, a request, sent by the server, for transferring control of the controlled device, wherein the request for transferring control of the controlled device is sent by the server after the server receives a request, sent by a second control terminal, for controlling the controlled device; sending (S22) to the server, by the first control terminal, a notification of agreeing to transfer control, so that the server notifies the second control terminal to establish a communication connection with the controlled device; and sending (S23) to the controlled device, by the first control terminal, an instruction of connecting with the second control terminal, so that the controlled device, after receiving the instruction, establishes a communication connection with the second control terminal and receives a control instruction sent by the second control terminal, receiving (S12), by the second control terminal, a notification, sent by the server, of authorizing to control the controlled device, wherein the notification is sent after the server determines that the first control terminal agrees to transfer control; and connecting (S13), by the second control terminal, communicatively with the controlled device to control the controlled device. <EOS>
