摘要： A handoff control method includes the following: Handoff status information of a first mobile host (MH) is collected. The handoff status information includes at least one parameter that is used for representing a status that happened during the first handoff from a source access point (AP) to a target AP. A handoff policy is generated based on the handoff status information, and used for optimizing a handoff process of an MH associated with the source AP. The handoff process occurs after the first MH is handed off from the source AP. The handoff policy is sent to the MH associated with the source AP, so the MH associated with the source AP can perform the handoff according to the handoff policy. A handoff control device and a system represent technical solutions that optimize the handoff process, reduce a total time delay of handoff, and increase a likelihood of successful handoff.

摘要： A load balancing method for a wireless communication system, which has a backbone network, more than one Access Point connected to the backbone network and more than one client. In the method, the client transmits a Probe Request message to the more than one Access Point; the Access Point monitors its load. If the Access Point is under an overload situation, it transmits a Probe Response message to the client by the minimum transmitting power. If the Access Point is under normal load situation, it transmits a Probe Response message to the client by normal transmitting power. The client preferentially chooses the Access Point under normal load situation to access based on the signal strength of the received Probe Respond message. The method thus provides the client with a priority of the Access Points, wherein the Access Point under an overload situation has a lower priority.

摘要： On vehicles on which only a single receiving antenna is provided or where a plurality of receiving antennas which are arranged side by side and are coupled to the forward and return conductors of a line conductor are provided, the phase angle of the received voltage is retained when the voltage drops below a given received level. If the level of the received voltage rises again, the prevailing phase angle of the received voltage can be compared with that of the retained received voltage. If the received voltages to be compared are found to be in phase opposition, it is deduced that a line conductor intersection point has been passed; if they are in phase, transient transmission interference is inferred. The phase angle of the comparative voltage is preferably retained by a flywheel oscillator, with the time offset between the prevailing received voltage and the comparative voltage preferably being determined by weighting the peak values of the two voltages.
摘要翻译：在仅设置单个接收天线的车辆或并排设置并且连接到线路导体的正向和返回导体的多个接收天线被提供时，接收电压的相位角保持在电压下降到给定的接收电平以下。如果接收电压的电平再次上升，则可以将接收电压的主要相位角与保持的接收电压的相位角进行比较。如果接收到的要比较的电压被认为是相位相反，则推断线路导线交点已经通过; 如果它们处于同相状态，则推断出瞬时传输干扰。比较电压的相位角优选地由飞轮振荡器保持，其中主要接收电压和比较电压之间的时间偏移优选地通过对两个电压的峰值进行加权来确定。
