A process control unit () causes a plurality of control-target processes to operate in a memory area of a size equal to or smaller than a limiting value x. When a stopping process is detected, a resource allocation unit () allocates a size of a usable memory area for each of the control-target processes as a relaxed limiting value. When the stopping process is detected, the process control unit () causes each of the control-target processes to perform fallback operation in a memory area of a size equal to or smaller than the relaxed limiting value allocated to the process by the resource allocation unit ().

Resource control device, resource control method, and computer readable medium

A wireless LAN system includes at least one LAN terminal wirelessly connected to a plurality of base stations, at least one IP terminal connected to an IP network, and a diversity device connected to the IP network and that relays packet transmission between the LAN terminal and the IP terminal via the IP network. The LAN terminal sequentially establishes association with a predetermined number of the base stations, and a plurality of data is transmitted parallelly via the predetermined number of the base stations, between the LAN terminal and the diversity device. At the receiving end, one of the plurality of data is selected and output.

Radio LAN system, diversity apparatus, and radio LAN terminal

A mobile radio communication system which does not need an omnidirectional channel for both a base station and a mobile station to track each other and uses only a narrow beam channel and can reduce a tracking time than before for an adjacent base station and a mobile station to search each other while a visiting area base station and the mobile station are communicating in the overlapped area. The base station and the mobile station comprise a unit for transmitting and receiving in forward or reverse channel, in different frequency, in different tracking channel using a narrow beam. Both the mobile station and the visiting area base station search the location each other, and after searched, they assign the frequency and the beam used in the tracking channel. At the same time, by comprising a searching slot in an information channel to search an adjacent base station while communicating with the visiting area base station, a tracking of other adjacent base station can be performed.
