Abstract: A method for transmitting data in a core cache server of a communication system, according to one embodiment of the present invention, comprises the steps of: receiving, from a source base station, a core cache search signal; selecting a relay core cache unit according to the received core cache search signal; and transmitting content data to a target base station through the selected relay core cache unit. A cache server for transmitting and receiving data in a communication system, according to another embodiment of the present invention, comprises: one or more core cache units for storing content data; a receiving unit for receiving, from a source base station, a core cache search signal; a control unit for selecting a relay core cache unit among the one or more core cache units according to the received core cache search signal; and a transmission unit for transmitting the content data to a target base station through the selected relay core cache unit. When the present invention is used, the source base station can continuously provide content to a terminal by transmitting session information and the content to a target base station during a handover of the terminal by using a logical interface between base stations in an LTE system, and in this case, a core cache function is additionally provided such that it is possible to smoothly provide the content to a base station even when moving to a server that does not have a cache function. Thus, backhaul costs caused by a handover are reduced and a user can be provided with improved quality of experience.

Abstract: A portable electronic device includes an audio input device and a processor. The processor is configured to obtain audio input data including a noise signal having an audio feature through the audio input device, to filter the audio input data using a neural network model to generate first audio output data, and to filter the first audio output data without using the neural network model to generate second audio output data. The first audio output data has a first changed audio feature corresponding to the audio feature and the second audio output data has a second changed audio feature corresponding to the audio feature.
