Method and apparatus for controlling traffic quality

A control server for controlling traffic transmission in a communication system, comprising:

• a transceiver configured to transmit and receive at least one signal;
• and
• at least one processor coupled with the transceiver and configured to:
• receive, at the control server from a terminal, a control plane message including information of an application corresponding to a network session, the information of the application including information on a category of the application,
• receive, at the control server from a node of a network, information related to a network congestion condition with respect to the network session, and
• determine a policy for controlling a traffic flow of the network session based on the information on the category of the application and the information related to the network congestion condition with respect to the network session, wherein the policy includes a quality of service (QoS) corresponding to the category and information on action to be taken by at least one of the control server, a gateway or the terminal in response to congestion associated with the application, and the quality of service includes at least one of frequency bandwidth information, transmission rate information, buffering permission time information and packet transmission priority, and the information on the action to be taken includes information on whether to block a packet transmission,
• wherein the traffic flow of the network session is controlled based on the determined policy.

An electronic device for transmitting and receiving traffic in a communication system, comprising:

• a transceiver configured to transmit and receive at least one signal;
• and
• at least one processor coupled with the transceiver and configured to:
• transmit, from the electronic device to a control server, a control plane message including information of an application corresponding to a network session, the information of the application including information on a category of the application, and
• transmit and receive, from the electronic device, at least one data on a traffic flow of the network session controlled based on a policy determined based on information on a network congestion condition related to the network session and the information on the category of the application, wherein the policy includes a quality of service (QoS) corresponding to the category, and information on action to be taken by at least one of the control server, a gateway or the electronic device in response to congestion associated with the application, and the quality of service includes at least one of frequency bandwidth information, transmission rate information, buffering permission time information and packet transmission priority, and the information on the action to be taken includes information on whether to block a packet transmission.
