The present disclosure discloses a configuration system, comprising: a client device, an embedded device, and a router. The client device is configured to establish a first connection with the embedded device in a point-to-point wireless connection mode, acquire access information of the router, and send the access information to the embedded device. The embedded device is configured to establish, according to the access information, a second connection with the router in a Wi-Fi mode while maintaining the first connection with the client device. The present disclosure also discloses a client device, an embedded device configuration method, and a computer readable storage medium.

A portable electronic device of an embodiment includes a plurality of secure elements and a communicator. The communicator performs communication with a reader/writer device to which an external device is connected using non-contact communication. The communicator changes a transmission destination to a secure element corresponding to a transmission destination identifier for identifying the transmission destination among the plurality of secure elements on the basis of the transmission destination identifier and change-instruction-information giving instructions to change the transmission destination, assigned to telegraph data received from the reader/writer device using the non-contact communication and transmits the telegraph data received from the reader/writer device to the secure element.

A control method that is achieved by a refrigerator application installed in portable terminal, the control method including the steps of instructing an operating system (OS) of portable terminal to connect to a refrigerator in operation in a software access point mode, and sending a service set identifier (SSID) of an access point and a password for connecting to the access point to the refrigerator. An SSID of the refrigerator that operates in the software access point mode, and a password for connecting to the refrigerator that operates in the software access point mode are incorporated in the refrigerator application in advance.

Embodiments of the present invention describe a feedback information transmission method and apparatus. The feedback information transmission method may include receiving, by a first terminal, first data sent by a second terminal. The method may also include sending, by the first terminal, feedback information for the first data to the second terminal in a first subframe, where there is second data to be sent by the first terminal in the first subframe. The feedback information may be carried in sidelink control information (SCI) of the second data, or the feedback information may be carried in a data packet carrying the second data. According to the embodiments of the present invention, the feedback information is carried in the SCI or the data packet carrying the second data.

An electronic device and an electronic-device-operating method are provided. The electronic device includes an embedded subscriber identity module (eSIM) embedded in the electronic device, the eSIM storing a first profile associated with a first communication service, a physical subscriber identity module (pSIM) configured such that a SIM card is capable of being removably attached thereto or capable of being inserted thereinto, the pSIM storing a second profile associated with a second communication service, a communication processor configured to control the eSIM and the pSIM, and a processor. The processor is configured to receive a signal indicating switching from a dual standby mode to a single standby mode, control a local profile assistant in device (LPAd) configured to control the eSIM in response to reception of the signal, delete a task associated with the eSIM in response to completion of disabling the LPAd, request deactivating of a protocol stack corresponding to the eSIM in response to deleting the task, and reset the communication processor in response to deactivation of the protocol stack.
