摘要： Apparatuses and methods for performing congestion control in a transmission control protocol (TCP) environment in a wireless communication system are provided. At least one recovery session is opened a preset time after a time-out occurs in an original session, and whether link recovery is achieved after the at least one recovery session is opened and before a preset maximum wait time elapses is monitored. If the link recovery is achieved, a transmission speed is recovered according to a scenario corresponding to a time when the link recovery is achieved.

摘要： Disclosed is a 5G or pre-5G communication system. To this end, an electronic device transmits a request message to a server through each of a plurality of communication paths at least based on a multi-radio access technology, and receives a video segment from the server through each of the plurality of communication paths according to the request message. The electronic device estimates a transmission quality at each communication path on the basis of video segments received for each of the plurality of communication paths at a radio search point satisfying at least one preset condition. The electronic device can determine, by the transmission quality estimated according to each of the plurality of communication paths and the preset reference transmission quality, one communication mode, among a plurality of communication modes, for designating at least one communication path for supporting the video streaming, among the plurality of communication paths.

摘要： Disclosed is a 5G or pre-5G communication system for supporting a data transmission rate higher than that of a 4G communication system such as LTE. A method for supporting a streaming service of a terminal, according to the present disclosure, comprises the steps of: requesting a streaming service from a server; receiving, from the server, metadata associated with the streaming service; and receiving predetermined configuration information and the streaming service, wherein the predetermined configuration information is included in a transmission control protocol (TCP) option.

摘要： 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 a long term evolution (LTE). A method for uploading data by a station (STA) in a mobile communication system supporting a plurality of radio access interfaces (RAIs) is provided. The method includes, upon detecting that there is content to be uploaded, determining whether a first RAI among the plurality of RAIs is available, and when the first RAI is available, transmitting a header message including information related to the content and a body message including at least one of a plurality of segments which are generated based on the content to a proxy server through the first RAI to upload the at least one of the plurality of segments to an original server.

摘要： 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 for performing a handover by a terminal in a wireless communication system is provided. The method includes measuring a signal quality of a first network and determining whether the handover is required based on the signal quality of the first network, when the handover is determined to be required, communicating data through both a connection with the first network and a connection with a second network during a delay period and measuring the signal quality of the first network, when the delay period ends, determining whether to perform the handover based on the signal quality of the first network at a time when the delay period ends, and performing the handover.
