Provided are a call request processing method and device. The method includes: obtaining state information of a second communication identification card located in a same terminal with a first communication identification card; processing a call request according to the state information, wherein the call request is used for calling the first communication identification card. According to the solution, the technical problem that because only one radio frequency transceiving chip is set in a dual-mode dual-card phone, if one card is in a communication state, a call to another card is easily lost is solved, thereby reducing call loss.

Call request processing method and device

The present disclosure provides an electronic device having a USB interface and a method for starting USB communication with such an electronic device, so as to solve the problem of a risk of damaging a mobile phone terminal device arising from sharing of an interface by a charger and a USB communication cable in the related art. In the electronic device, a port GPIO of a baseband chip is connected to a pin USB_VBUS of a USB interface of the baseband chip; based on this circuit, a power management chip detects a state of plugging-in-or-pulling-out of the charger and generates a corresponding interrupt request; and the baseband chip controls the GPIO to output a corresponding level according to the interrupt request. By connecting the port GPIO and the pin USB_VBUS and controlling an output level of GPIO with a software, a high level or a low level (as a triggering signal for starting or terminating the USB communication) is input to the pin USB_VBUS, thus avoiding damage to the device.
