Abstract: Control of an existing wireless network is limited with respect to certainty of information transmission and delay time since the control is performed through direct communication between wireless access points. Also, the effective determination throughout a network could not be made since a subject for making a decision on the situation separately made a decision on each wireless access point was disturbed when a plurality of wireless access points affected each other. A method for controlling wireless network at a switch provided in the present invention is a method for managing a plurality of wireless access points in the center at a protocol level higher than an existing method, therefore, the determination can be made on the optimized situation throughout the network and the wireless network can be effectively managed during a short delay time since the method corresponds to the each wireless access point by one to one. Furthermore, a wireless network can be more widely managed by sharing wireless network information of the corresponding area with other switches through the network.
Abstract translation: 由于通过无线接入点之间的直接通信进行控制，所以现有无线网络的控制在信息传输和延迟时间的确定性方面受到限制。 而且，当多个无线接入点相互影响时，不能进行整个网络的有效确定，因为对每个无线接入点单独作出决定的对象被干扰。 本发明提供的交换机控制无线网络的方法是一种以比现有方法更高的协议级别管理中心的多个无线接入点的方法，因此，可以对整个优化情况进行确定 可以在短的延迟时间内有效地管理网络和无线网络，因为该方法对应于每个无线接入点一对一。 此外，通过与其他交换机通过网络共享相应区域的无线网络信息，可以更广泛地管理无线网络。

Abstract: PURPOSE: An error correcting method in a communication system and a correcting apparatus for the same are provided to reduce the number of retransmission caused by a frame error, thereby improving a network transmission rate. CONSTITUTION: A modulator checks a frame of a receiving signal and detects the position of data having high probability of generating an error. An error code substituting unit finds the position of data having high probability of generating an error by referring to a demodulator and searches for a different value to substitute regarding the data in the found position. A frame error checking unit checks again whether an error occurs or not in the transferred frame and delivers the transferred frame to an upper layer block or the error code substituting unit according to the checking results. [Reference numerals] (601) Demodulator; (602) Frame error inspection unit; (603) Error code substituter; (604) Upper layer block
