    摘要: A method, a mobility management unit and a gateway unit for restricting access and communication of a machine type communication (MTC) device are provided by the present invention. The method includes: a mobility management unit judging whether an access request or a service request of the MTC device is currently in a permission period according to the permission period of the MTC device; when the access request or the service request is not in the permission period, rejecting the access request or service request of the MTC device and notifying the MTC device of the rejection cause and/or the permission period at a meantime. The present invention can ensure that the MTC device only communicates in the permission period, and the MTC device is restricted to access the network or communicate in the non-permission period according to the requirement of the operator.

    摘要: A method and a system for notifying an attribute of an Internet Protocol (IP) address and a Serving Gateway (SGW) are disclosed. When an SGW is taken as a User Equipment's (UE's) SGW, the new SGW can be notified of an attribute of the UE's IP address. The technology of notifying an attribute of an IP address in the disclosure can ensure that the new SGW can learn the attribute of the UE's IP address in time when the new SGW is taken as the UE's SGW. Therefore, a charging gateway function entity connected with the new SGW can accurately charge the UE according to the attribute of the IP address.

    摘要: A lateral high-breakdown voltage semiconductor device is provided in which the breakdown voltages of elements as a whole are improved, while suppressing increases in cell area. A track-shape gate electrode surrounds a collector electrode extending in a straight line, a track-shape emitter electrode surrounds the gate electrode, and a track-shape first isolation trench surrounds the emitter electrode. A second isolation trench surrounds the first isolation trench. The region between the first isolation trench and the second isolation trench is an n-type isolation silicon region. The isolation silicon region is at the same potential as the emitter electrode. In the cross-sectional configuration traversing the gate electrode, the depth of the p base region in an interval corresponding to an arc-shape portion of the gate electrode is shallower than the depth of the p base region in an interval corresponding to a straight-line portion of the gate electrode.

    摘要: A DC chopper comprising a control unit and a power circuit and a DC chopping method for a DFIG (doubly fed induction generator) system are provided. The input terminal of the control unit is coupled to a DC capacitor of a converter to detect a DC voltage. The power circuit includes input terminals, an overvoltage protection module, a rectifier module and output terminals. The overvoltage protection module comprises at least one discharge unit formed from a discharge resistor and a switch element, and the rectifier module is coupled in parallel to the overvoltage protection module. When a grid voltage drops, the control unit outputs a corresponding control signal to drive the switch element to be ON or OFF, and the output terminal of the power circuit absorbs a portion of rotor inrush current, so as to impose over-current protection.
