Adaptive non-real-time traffic control method and terminal for same

A method performed by a terminal device for adaptively controlling traffic, the method comprising:

• transmitting a policy request signal to a policy provider;
• receiving a policy answer signal in response to the policy request signal;
• performing traffic transmission and reception including downloading a traffic answer signal in response to a traffic request signal from a content provider via a path network;
• detecting a network status of the path network based on the policy answer signal;
• determining whether or not to perform traffic control based on the network status during the downloading;
• and
• controlling the downloading based on a result of the determining.

A server for controlling a policy, the server comprising:

• a communicator configured to
• communicate with a terminal device via a path network, and
• receive a policy request signal from the terminal device, the policy request signal including transmitter identification information on the path network;
• a device interlocker configured to receive an overloaded transmitter list from a transmitter load manager;
• a network detector configured to detect network status of the terminal device assigned to the path network;
• a policy determiner configured to
• perform a function of managing a policy related to data traffic based on the detected network status,
• compare the transmitter identification information with the overloaded transmitter list to check whether the terminal device is located in overload area, and
• generate a policy answer signal including a policy determined based on a result of the checking.
