Aspects of the present disclosure provide techniques for improving emergency calls by a user equipment (UE) in certain scenarios. The techniques generally include receiving a trigger for the UE to perform a circuit switched (CS) emergency call via a first subscriber identity module (SIM) that is serving as a default data subscriber (DDS), attempting the CS emergency call via the first SIM, detecting a failure to perform the CS emergency call via the first SIM, and re-attempting the CS emergency call via a second SIM, in response to the detection.

Method for improved emergency call

An LED light device and a circuit preparation method thereof are provided. The LED light device includes a base, an LED light unit, and a lamp shade. The LED light-emitting unit and the lamp shade are arranged on the base. The lamp shade covers the LED light-emitting unit inside. The circuit preparation method includes following steps of: providing a base which is a physical entity having a three-dimensional structure on the surface thereof; coating a circuit layer on the base surface through a programmable coating equipment, manual coating or the combined mode, wherein the circuit layer is a liquid or powder coating containing metal materials, and the thickness of the circuit layer is 20 &#x3bc;m or more; baking the base coated with the circuit layer at the high temperature of 100-1,000&#xb0; C. until the circuit layer is dried; and obtaining a base having a three-dimensional circuit after cooling.
