Abstract
A control method of emergency call and user equipment using the same method are provided. The control method contains the following steps. In a first Public Land Mobile Network (PLMN), an emergency call is originated. Whether a radio resource related failure indication is received is determined. In response to the failure indication being received, one of second PLMNs supported by the user equipment is selected, and the emergency call is originated again. Therefore, a probability of successfully establishing an emergency call would be elevated.
