Abstract: 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.

Abstract: Disclosed is a method for receiving streaming service data in a mobile communication system supporting a plurality of radio access interfaces, comprising the steps of: operating in a first mode for receiving, from a server, streaming service data through a first interface among the plurality of radio access interfaces; and determining a transition to a second mode for receiving the streaming service data by using at least two radio access interfaces according to a radio network currently being used in the first mode.

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 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.

Abstract: The present disclosure relates to a device and method for transmitting and receiving data to and from a terminal in a wireless communication system. The method of operating the terminal in the wireless communication system may include the processes of comparing pre-stored domain name service (DNS) cache information with DNS inquiry information in a DNS inquiry if the DNS inquiry on a host is received from a uniform resource locator (URL) protocol handler, and transmitting internet protocol (IP) address information corresponding to the host to the URL protocol handler according to a compared result.
