An electronic atomization apparatus with a switch-closed atomizer and an electronic simulation cigarette are disclosed. The electronic atomization apparatus comprises a battery rod (), an atomizer () arranged on a top end of the battery rod (), an atomization liquid storage device (), a sleeve () and a suction nozzle upper cover (). When in use, the atomization liquid storage device is placed in the sleeve, and the suction nozzle upper cover is sleeved on the sleeve. The atomization liquid storage device is pushed to move down by rotating the suction nozzle upper cover, while the atomizer-abuts against a sealing rubber (), so that the atomization liquid storage device and the sealing rubber () slide relative to each other in opposite directions, so as to open a liquid outlet () of the atomization liquid storage device to communicate with a liquid inlet () of the atomizer.

Disclosed are systems and methods for providing ring back tones in a communication network. At first, a ring back tone device for storing and playing the ring back tone customized by a subscriber is established in the communication network. Whether a subscriber is a ring back tone service register subscriber is judged with a certain triggering mode, such as intelligent network triggering, signaling interception triggering, call forwarding triggering or switching device triggering. If it is judged the subscriber is a ring back tone service registered subscriber, a connection between the originating switching device and the terminating switching device and a connection between a switching device and the ring back tone device are established. When the called terminal is idle, the ring back tone device provides a piece of customized ring back tone to the calling subscriber for replacing traditional ring back tone.
