摘要： Disclosed is an automatic speed changing device in which speed is automatically changed according to a predetermined amount of rotation without user's arbitrary manipulations. The automatic speed changing device of the present invention comprises a hub unit including a hub shaft formed with a sun gear, and a hub shell surrounding the sun gear and having a first ratchet ring and an inner gear formed on an inner peripheral surface of the hub shell; a first travel unit including a driver for rotating the hub shell while closing the other side of the hub shell, and a driven sprocket for rotating the driver by receiving power from a driving sprocket; a second travel unit including a first carrier disposed within the hub shell and mounted at one side thereof with a plurality of planetary gears engaged with the sun gear and the inner gear to rapidly rotate the hub shell, and a second carrier extending from the other side of the first carrier to the driver; and a conversion unit including a second ratchet ring interposed between the driver and the second carrier to transmit rotational force from the rotating driver to the second carrier and the planetary gears of the first carrier, and a conversion spring interposed between the first and second carriers to return the second ratchet ring when pedals of a bicycle are not operated and the bicycle is stopped.

摘要： Provided is a handover method, in which a call manager of a network having a Circuit Switching (CS) network, a Long Term Evolution (LTE) network, and an Internet Protocol Multimedia Subsystem (IMS) network, provides handover, from the LTE network to the CS network, to a terminal that uses one radio channel. The handover method includes upon receiving a request for handover from the terminal via a node of the LTE network, establishing a line to a Mobile Switching Center (MSC) of the CS network; sending, to the call manager, a request for a change in a session to another party's terminal in communication with the terminal, to establish an Internet Protocol (IP) bearer between the call manager and the other party's terminal; and sending a handover command to the terminal during the establishment of an IP bearer, to establish a radio channel to the base station of the CS network.

摘要： A method and apparatus for performing handover on a voice call between a packet network system and a circuit network system is provided. Considering a communication environment where a UE cannot simultaneously use radio resources of both the next generation mobile communication system (LTE) and the legacy mobile communication system (e.g., GSM/WCDMA), the present invention proposes an SCSE for performing signal translation between the packet switched network and the circuit switched network and anchoring a voice call in the application level, and supports a continuous voice call using the SCSE.
