Abstract: Disclosed is a method of managing congestion by a Policy Control and Charging Rules Function (PCRF). The method includes receiving at least one piece of video flow related information; receiving, from an evolved Node B (eNB), congestion state information for the eNB and at least one User Equipment (UE); determining a data transmission rate of at least one video flow on the basis of the received congestion state information and the received video flow related information; and adjusting the data transmission rate of the at least one video flow on the basis of the determined data transmission rate.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method and apparatus of dynamically operating a bearer in a wireless communication system is provided. The bearer operating method of an evolved Node B (eNodeB) includes: setting a dynamic bear for user equipment (UE) where a bit rate is dynamically adjustable; receiving a report message, including channel status and/or video buffer status of the UE, from the UE; determining a modified bit rate to be applied to the dynamic bearer and time information to which the modified bit rate is applied; and transmitting the modified bit rate and the time information to the UE.

Abstract: Disclosed are a network-based quality of experience (QoE) provisioning method and apparatus for mobile video applications. A QoE provisioning method of a policy and charging rules function (PCRF) in a network includes collecting, by the PCRF, information for QoE estimation of a data flow from a user equipment measurement apparatus and a network measurement apparatus in the network, transmitting, by the PCRF, a request for the QoE estimation for the data flow, to a QoE estimation unit in the network, the data flow including information used for the QoE estimation, and transmitting, by the PCRF, a request for QoE adjustment to a server that transmits the data flow, based on the QoE estimated by the QoE estimation unit and the QoE required for the data flow.
