Abstract: The present application provides a 4-dimensional trajectory regulatory decision-making method for air traffic. The method includes: acquiring a node vector set of a target flight to obtain a target node vector set; acquiring the node vector set of all historical flights simultaneously to obtain a historical node vector set; acquiring a similarity between the target node vector set and the node vector set of each historical flight in the historical node vector set to obtain a plurality of similarity data; acquiring a similarity data which is greater than a preset similarity data from plurality of similarity data to obtain a target similarity data; acquiring a historical flight to which the target similarity data belongs to obtain a target historical flight; acquiring a historical decision-making instruction of the target historical flight to obtain a target decision-making instruction.

Abstract: A method, server and terminal for managing digital television business data are disclosed in the present invention. By means that the mobile terminal forwards a business request, which is required to be sent from a digital television reception terminal to a business server, to the business server and the business server provides the corresponding business service for a user via a unidirectional digital television network, the present invention solves the problem that the unidirectional digital television reception terminal in the art can not obtain bidirectional interactive television business data, and allows the user to enjoy bidirectional interactive television business functions without having to replace the digital television reception terminal and the unidirectional digital television network, thereby greatly enhancing user experience.

Abstract: A method for a mobile terminal to control a digital television receiving terminal includes that: the mobile terminal provides a first remote control interface; the mobile terminal sends a selection instruction to the digital television receiving terminal, wherein the selection instruction instructs the service which a user selects on the first remote control interface; and the mobile terminal switches to a second remote control interface corresponding to the service which the user selects on the first remote control interface. A terminal includes a sending module for sending the selection instruction to the digital television receiving terminal, wherein the selection instruction instruct the service which the user selects on the first remote control interface; and a switching module for switching to the second remote control interface corresponding to the service which the user selects on the first remote control interface.
