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.

Device and method for accessing multiple networks in wireless communication system

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.

Video streaming apparatus and method in electronic device

The present invention relates to a proxy apparatus and to a caching method of same. The caching method of the proxy apparatus according to one embodiment of the present invention includes the steps of: receiving a transmission request for content that can be divided into a plurality of blocks and instruction information for the playback position of the content from an external device; obtaining a header block that includes the header of the content when receiving the transmission request; identifying an intermediate block that corresponds to the playback position using the header; requesting and obtaining the intermediate block through a network when the identified intermediate block is not cached in the proxy apparatus; and transmitting to the external device at least a portion of the header and at least a portion of the intermediate block corresponding to the request. According to one embodiment of the present invention, even in a case where the size of a piece of content is great but only a specific portion is used, an efficient caching method and apparatus can be provided.

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.

Method for handover in wireless communications system and apparatus supporting the same

The present invention is to process a request of an application layer in an electronic device, and a method for operating the electronic device comprises transmitting a request signal through a first interface, and, when a response signal corresponding to the request signal is not received before a timer expires, retransmitting another request signal through a second interface. The request signal and the another request signal correspond to a single request signal generated in the electronic device. Also, the present invention includes other embodiments than the described embodiments.

Application layer request processing device and method using multiple interfaces in electric device

A handover method in a mobile CCN. In the method, when detecting a UE performing a handover, a source local CCNx node caches data directed to the UE. The source local CCNx node transmits a request to stop transmission of the data directed to the UE to a target local CCNx node based on a condition. The target local CCNx node requests the source local CCNx node to stop transmission of contents that are being cached. The source local CCNx node transmits cached contents to the target local CCNx node. The target local CCNx node requests a CCNx entry node to stop transmission of specific contents based on a condition. The CCNx entry node transmits contents to the target local CCNx node. When detecting, the UE completing the handover, the target local CCNx node transmits the contents received from the CCNx entry node to the UE.
