Abstract:
The present disclosure relates to an apparatus and a method for controlling Transmission Control Protocol (TCP) connection close to improve a battery life time of a client such as a smart phone in a wireless communication system are provided. A method of operating a client in a wireless communication system includes determining a data transfer inactivity time of at least one of TCP connections, and closing the at least one of TCP connections at the data transfer inactivity time.
Abstract:
Provided is a method for offloading data traffic by a Mobility Management Entity (MME) in a wireless communication system. The method includes determining a Packet Data Network (PDN) to connect to for providing a service requested by a User Equipment (UE), upon receiving a connection request message requesting connection between the UE and the PDN from the UE, selecting a gateway disposed closest to a Radio Access Network (RAN), sending a permit message permitting a request for connection between the UE and the PDN to the UE, and setting an Evolved Packet Service (EPS) bearer for transmission and reception of data traffic related to a service requested by the UE between the UE and the gateway.
Abstract:
The present disclosure relates to a technique for a sensor network, machine to machine (M2M) communication, machine type communication (MTC) and the Internet of Things (IoT). The present disclosure can be used for intelligent services (services related to a smart home, a smart building, a smart city, a smart car or a connected car, healthcare, digital education, retail business, security and safety and the like) on the basis of the technique. An operating method of a tethering device, according to an embodiment of the present invention, comprises the step of: selecting a first network and/or a second network according to the characteristic of a data request message received from a client device; and transmitting, to the client device, a response message received from a server through the at least one selected network.
Abstract:
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.
Abstract:
The present disclosure relates to a sensor network, Machine Type Communication (MTC), Machine-to-Machine (M2M) communication, and technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the above technologies, such as a smart home, a smart building, a smart city, a smart car, a connected car, healthcare, digital education, smart retail, security and safety services. A method and an apparatus for controlling aperiodic traffic in an electronic device are provided. The method includes determining a delay allowed time for first traffic associated with the first application based on a prediction time of generation of second traffic associated with a second application and processing the first traffic associated with the first application based on the delay allowed time.

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:
The present disclosure relates to a sensor network, Machine Type Communication (MTC), Machine-to-Machine (M2M) communication, and technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the above technologies, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method and a User Equipment (UE) for controlling access to location information about the UE are provided. The UE includes a controller configured, upon sensing access to the location information about the UE by an application operating in an operating system (OS) of the UE, to match a rule defining access authorization of the application to the location information, and to determine whether to allow or deny access of the application to the location information based on the access authorization, and a display configured to display a screen under control of the controller.
