摘要： An object of the present invention is to achieve the reduction of EMI, the improvement of conversion efficiency, and simplification of the input filter. Provided is a switching power supply device that comprises: a chopper circuit that turns on/off the passage of a current to an inductor by means of a switching element; and a switching control circuit that switches the switching element so that an input voltage and an input current have the same phase and a similar shape. The switching control circuit is configured to switch the switching element at a switching frequency that is proportional to an input voltage dependent term of a formula that expresses a third harmonic component of ripples of the current flowing to the inductor.

摘要： An IP multicast system includes: an IGMP proxy unit set in an access network which provides information of a multicast group to which a terminal belongs. The IGMP proxy unit receives data sent from a multicast data source, and sends the data to a base station which then sends the data to the terminal. The IGMP proxy unit simplifies IP multicasting in the mobile network and makes the transfer of multicast data transparent with respect to the core network of the mobile network. This system can support mobile communication networks as WCDMA, CDMA2000, GSM and TD-SCDMA.

摘要： The embodiment of the present invention provides a method for establishing a route, which includes searching a target node by a node from a first level node group according to first level route information, returning to query a result or data saved by the target node if the target node is found, otherwise executing the following step; searching a target node by the node from a higher level node group according to higher level route information, returning to query a result or the data saved by the target node if the target node is found, otherwise repeating the step. Through the hierarchical communication system, most of the flows of daily service operations in the communication network are limited within a small region, thereby preventing from excessively occupying the band width of a backbone network being originally not wide enough.
