Abstract

Disclosed are a method and a device for remote control of a terminal, in which authentication information is requested from the control terminal after a control request for a controlled terminal is received; and when the identification information from the control terminal is correct, dynamic identification information of the controlled terminal for a control service is obtained and sent to the control terminal. The method and the device according to certain embodiments do not require a dedicated dynamic domain name resolution server. The communication costs of a user may be reduced. Since a successful authentication is a precondition for obtaining dynamic identification information, the communication security is improved.
