    Abstract: Provided are an electronic device and a method for controlling the electronic device. According to the disclosure, an electronic device configured to perform a radio access network function comprises: a communication interface comprising communication circuitry, a processor operatively connected with the communication interface, and a memory operatively connected with the processor, wherein the memory stores instructions which, when executed, cause the processor to: receive, via the communication interface, wireless communication data transmitted via a radio access network, process the received wireless communication data based on a radio access network protocol by at least one first virtualized module corresponding to at least one function of the radio access network, identify an abnormal sign based on the received wireless communication data or a result of processing of the wireless communication data by the at least one first virtualized module, transfer security information indicating the abnormal sign to a second virtualized module by the at least one first virtualized module, and determine an expected security threat on the radio access network based on the security information indicating the abnormal sign by the second virtualized module.

    IPC: G06F3/044

    Abstract: A sensing device includes a touch panel including first and second sensor electrodes, and a touch panel controller acquiring a sensing signal from the touch panel and detecting a user input based on the sensing signal. The touch panel controller acquires the sensing signal from at least one of the first sensor electrodes and the second sensor electrodes in a first mode operating at a first power. The touch panel controller selects a first transmitting electrode, a second transmitting electrode, and receiving electrodes from one of the first sensor electrodes and the second sensor electrodes, inputs a first driving signal to the first transmitting electrode, and inputs a second driving signal having a phase difference of 180 degrees with respect to the first driving signal to the second transmitting electrode in a second mode operating at a second power and a third mode in which a sensing operation is performed.
