Quality of experience enhancement through feedback for adjusting the quality of service in communication networks

摘要

A method of enhancing Quality of Experience (QoE) associated with an application flow for an end-user in a communication network comprises: receiving a packet belonging to the application flow, the packet comprising QoE information determined based on previous packets exchanged within the application flow; decoding the QoE information from the received packet; and adjusting a QoS mechanism for the packet, based on the decoded QoE information for enhancing the QoE of the application flow. A network node for carrying out this method is disclosed. Also, a method for relaying QoE associated with an application flow for an end-user in a communication network comprises: receiving packets belonging to the application flow; calculating QoE information based on the received packets; and sending the calculated QoE information back to the communication network, the QoE information being included in a packet belonging to the application flow. A network node for carrying out this method is disclosed.

1. A method of enhancing Quality of Experience (QoE) associated with an application flow for an end-user in a communication network, the method comprising:
receiving a data packet as part of the application flow, at a communication interface of a network node, the data packet comprising a payload containing application data and a header containing QoE information associated with the application flow, the QoE information determined based on previous data packets exchanged within the application flow; decoding the QoE information from the header of the received data packet by a processor of the network node; adjusting a QoS mechanism for the received data packet of the application flow, based on the decoded QoE information for enhancing the QoE associated with the application flow; and sending the data packet to another network node in the communication network, according to the adjusted QoS mechanism.
