Embodiments of the present invention provide a train control method for maximizing utilization of regenerative energy. The method mainly comprises: working out a matching error &#x394;T of a current matched pair of trains Mx (i, j) of a station in the current running situation; and comparing the matching error &#x394;T with a preset maximum adjustable error &#x394;Tof the current matched pair of trains Mx (i, j) of the station and determining a strategy for adjusting train running of the current matched pair of trains Mx (i, j) according to comparison results.

The present invention discloses a calculation method of movement authority for communications-based train control system, comprising: handling a route information for a train, and determining a searching range of the train according to the route information; initializing the limit of movement authority with the end position of the searching range; searching for static obstacles within the searching range, and successively determining whether each static obstacle meets the safety requirements for train operating, if not, setting the position of the last static obstacle within the searching range as the limit of the movement authority; if so, modifying the limit of movement authority as the end of route having been matched; searching for dynamic obstacles within the searching range, and determining whether there is a train, if so, modifying the end of movement authority as the beginning point of the track section where the train is occupying; if there is no dynamic obstacle within the searching range, modifying the final end of movement authority as the position of the last static obstacle within the searching range. In accordance with the present invention, it is possible to increase line capacity and improve traffic fluidity for rail transit.

A Wireless Local Area Network (WLAN) handover method is provided. The method comprises a mobile station receiving probe frames sent in a predefined time interval from a current associated access point and an adjacent access point during a preset time period. The station obtains and stores a signal strength for each access point based on the beacon frames. The station performs fuzzy processing of the signal strengths and change rates of the signal strengths to obtain fuzzy data characterizing levels of the signal strengths and the change rates. The station performs fuzzy reasoning based on the fuzzy data to obtain reasoning outputs. A target access point is determined by the station based on the reasoning outputs. The station authenticates with the target access point, and sends a re-association request frame to the target access point. Re-association is established after a re-association response frame is received by the station.
