Abstract: The present invention relates to a method for searching and releasing an abnormal subscriber station in a wireless portable Internet system, and an apparatus using the same. The apparatus searches for an abnormal group including abnormal subscriber stations based on a ranging code provided in a periodic ranging process, and searches for an abnormal subscriber station by transmitting a connection maintenance message to subscriber stations included in the abnormal group so as to check an operation status of the respective subscriber stations. In addition, the apparatus releases a connection of an abnormal subscriber station. Therefore, waste of radio resources allocated to the abnormal subscriber station can be prevented, thereby achieving efficient resource management. Further, a secondary search process is performed only for subscriber stations included in an abnormal group, thereby preventing a system load from occurring when searching for an abnormal subscriber station.

Abstract: A collaborative system that includes automatic monitoring and management of reflector/servers and clients. The reflectors are in a logical cluster although their physical locations may be anywhere in the world. Reflector to reflector performance and status is continuously monitored. If a reflector-to-reflector link goes down or is underperforming, the reflector cluster is rerouted to provide desired performance. Clients are monitored and provide information via the network to register/management servers. A best path for the client capabilities is calculated and established. If network performance deteriorates, there are a tiered selection of session modifications that are initiated to compensate. These include reducing video detail levels, reducing number of video streams, reducing size of video windows, adjusting frame rate, and other corrective measures. The client software includes the ability to accept plug-in applications and functionality for customizable operation.
