Method and apparatus for managing user quality of experience (QoE) in mobile communication system

A software defined networking (SDN) switch for measuring a quality of experience (QoE) on a communication path between the SDN switch and a quality measurement protocol receiver, the SDN switch comprising:

• an interface configured to transmit and receive a message to and from other apparatus;
• and
• a controller configured to:
• receive, from a SDN controller, a quality measurement request message including type information of a service,
• generate a standard probe packet based on the type information of a service using a user traffic emulation function,
• measure the QoE of the communication path using the standard probe packet, and
• transmit, to the SDN controller, a QoE test reply message including quality related information based on the measurement of the communication path, wherein the quality measurement request message and the QoE test reply message are transmitted as being included in an OpenFlow message.

A method for controlling a quality of experience (QoE) measurement on a communication path between a software defined networking (SDN) switch and a quality measurement protocol receiver in a SDN controller, the method comprising:

• receiving, from a user, a QoE measurement condition including type information of a service;
• transmitting, to the SDN switch, a quality measurement request message based on the QoE measurement condition;
• receiving, from the SDN switch, a QoE test reply message including quality related information;
• and
• providing, to the user, quality related information based on the QoE test reply message,
• wherein the quality measurement request message and the QoE test reply message are transmitted as being included in an OpenFlow message.

A software defined networking (SDN) controller for controlling a quality of experience (QoE) measurement on a communication path between a SDN switch and a quality measurement protocol receiver, the SDN controller comprising:

• a QoE application included in the SDN controller configured to receive a QoE measurement condition from a user and provide quality related information to the user;
• a control protocol layer configured to:
• transmit, to the SDN switch, a quality measurement request message based on the QoE measurement condition, and
• receive, from the SDN switch, a QoE test reply message including quality related information;
• and
• a control module layer configured to provide an interface between the QoE application and the control protocol layer,
• wherein the quality measurement request message and the QoE test reply message are an OpenFlow message.
