The present disclosure relates to a pre-5-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4-Generation (4G) communication system such as long term evolution (LTE). A method of operation of an electronic device includes generating streaming data, determining a traffic pattern of the streaming data based on an encoding setting parameter, a data transmission speed and a data generation speed of the streaming data, and transmitting the streaming data based on the traffic pattern.

Apparatus and method for transmitting streaming data in wireless communication system

A method and apparatus for transmitting and receiving data in a wireless communication system is provided. A method of a mobile station includes: storing data received from a server in a buffer; transmitting, to the server, a request message for updating a quality of the data stored in the buffer from a first quality to a second quality based on at least one of an available bandwidth and a buffer level; and receiving data of the second quality from the server.

Method and apparatus for transmitting and receiving data in wireless communication system

A 5G or a pre-5G communication system supports a higher data transmission rate than a system after a 4G communication system such as LTE. A transmission device in a wireless communication system according to an embodiment of the present disclosure includes: a control unit that determines a maximum size of data that can be transmitted, based on network information, and determines transmission speeds of multiple transmission control protocol (TCP) connections, based on the size of the data that can be transmitted, respectively; and a communication unit that transmits data to a reception device through the multiple TCP connections based on the transmission speeds. A reception device in a wireless communication system according to an embodiment of the present disclosure includes: a control unit that determines a period for transmitting a response message, based on at least one of whether received data has a loss and available amount of a reception memory of the reception device; and a communication unit that transmits the response message to the transmission device according to the determined period.

Apparatus and method for controlling data transmission speed in wireless communication system

The present disclosure relates to a pre-5-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4-Generation (4G) communication system such as Long Term Evolution (LTE). An electronic device for providing a streaming service includes a controller, an encoder operatively coupled with the controller, and a transmitter operatively coupled with the control unit, wherein the controller is configured to provide a network available bandwidth estimated in a transmission layer of the electronic device from the transmission layer to an application layer, generate stream data from initial data based on the network available bandwidth, and transmit the stream data to another electronic device.

Device and method for streaming service

The present invention relates to a method and an apparatus for transmitting contents in a mobile communication network. According to one embodiment of the present invention, the method for receiving the contents of user equipment (UE) in a mobile communication system equipped with a local server which is connected to a base station (eNB) and copies partial contents of an external content server and maintains the copied contents, can include: a content determination step of determining whether the selected contents are the contents provided from the local server when a content selection input is received; a request transmission step of transmitting a content transmission request message to the base station (eNB) when the contents are the contents provided from the local server; and a content reception step of receiving the contents from the base station. According to one embodiment of the present invention, the present invention provides the method and the apparatus for efficiently receiving the contents which reduce resources used for receiving the contents and shorten a delay time.

Method and apparatus for receiving contents in mobile communication system

The present invention relates to a wireless communication system and a method for managing a cache server in the wireless communication system, the invention includes a step for checking a regional cache server to transmit contents when a DNS (Domain Name System) request a message for receiving contents acquired from a terminal, and a step for transmitting the contents by the cache server according to a contents request message received from the terminal. These steps can prevent the same data from being transmitted several times through a wireless communication network. Therefore, network usage associated with the service is reduced, and the network can be used more efficiently.
