Abstract: An optical element driving mechanism is provided and includes a fixed assembly, a movable assembly, a driving assembly and a stopping assembly. The fixed assembly has a main axis. The movable assembly is configured to connect an optical element, and the movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The stopping assembly is configured to limit the movement of the movable assembly relative to the fixed assembly within a range of motion.

Abstract: A method for searching network carrier using an electronic device includes receiving a request for a voice service from a user. The electronic device requests a server for a network carrier through which the electronic device can be connected to a network providing the voice service. A message is received from the server. When the received message comprises the network carrier, a connection is established between the network and the electronic device using the network carrier. The voice service is provided for the user through the network.
