Disclosed are a method and apparatus for controlling data transmission rate in a wireless communication system. The method for controlling transmission rate of a server according to the present invention comprises the steps of: determining an uplink transmission data rate of a first packet received from a terminal; transmitting a first parameter for controlling to increase the uplink transmission data rate; determining whether the uplink transmission data rate of a second packet received based on the first parameter increases; and transmitting a second parameter for controlling change of the uplink transmission data rate based on the determination result.

Method and apparatus for controlling data transmission speed in wireless communication system

The present invention relates to a method and an apparatus for transmitting and receiving information between servers in a contents transmission network system and, more particularly, to a method and an apparatus for transmitting and receiving information between a core node and an edge node belonging to a contents transmission network. To accomplish the objective mentioned above, a method for receiving, by a receiving server, information in a contents transmission network according to one embodiment of the present invention comprises the steps of: receiving first information from a transmission server; determining a transmission unit of the first information on the basis of the received first information; transmitting, to the transmission server, a second information transmission request including information on the determined transmission unit; and receiving, from the transmission server, second information generated on the basis of the information on the transmission unit. According to an embodiment of the present invention, the method and the apparatus for transmitting and receiving information between servers in a contents transmission network system can generate compressed information on the basis of original information sought to be transmitted between servers, whereby it is possible to obtain an effect of improving optimal compression efficiency, transmission efficiency between servers, and performance regarding the delay time between both communication ends.

Method and apparatus for transmitting and receiving information between servers in contents transmission network system

The present invention relates to the transmission of traffic in a mobile communication system and, more particularly, to a method and device for transmitting traffic in consideration of a quality of service (QoS) characteristic of the traffic. The purpose of the present invention is to efficiently provide a QoS differentiated according to traffic in consideration of a traffic type and a content provider in a network congestion situation of the mobile communication system.

Method and device for providing transmission differentiation in mobile communication system

An operation method of a server in a communication system, an operation method of an electronic device, the server, and the electronic device are provided. The operation method of the server includes determining a variation type of a buffering delay based on a packet transmission delay of a terminal, determining control information for controlling an uplink transmission rate of the terminal according to the variation type, and transmitting the control information.

Apparatus and method for controlling downlink throughput in communication system

The present invention relates to a network structure for effectively applying a software-defined networking (SDN) technology to an LTE network and an operation of a system on the basis of the same. The present invention therefore provides a method for controlling communication by an SDN controller in an SDN-based wireless communication network, the method comprising the steps of: receiving information on a UE from a gateway controller as the UE initially accesses an eNB; selecting at least one Openflow switch (OFS) for processing traffic of the UE on the basis of the information; and transmitting a request for setting a packet forwarding rule for processing the traffic of the UE to the at least one OFS.
