摘要： A mobile node is arranged to perform a high-quality hand-over operation for eliminating an interruption time in communication and keeping the continuance of communication excellent. The mobile node has a function of interfacing with networks and includes a network quality monitor, a hand-over controller, and a network controller. The network quality monitor operates to monitor a network quality based on at least one of an intensity and a radio bandwidth of a radio wave received by network devices. The hand-over controller performs the hand-over operation of transmitting a care of address to an address registering destination in response to a state of the network quality before a communication is disconnected, changing a route of communication information, and switching a connecting destination into a new network. The network controller receives a response that indicates an update of the care of address in the address registering destination and keeping a function of receiving data from the network before being switched until the communication is disconnected.

摘要： A network station stores therein a frame scheduling table including a plurality of pieces of scheduling information obtained by scheduling, in advance, transmission/reception timing of wireless frames that are transmitted/received by wireless communication terminals each of which is configured so as to implement a plurality of wireless communication methods, while using a wireless communication method corresponding to the network side and while using a wireless communication method corresponding to the local side. When the network station receives a notification indicating that a radio wave interference is detected, from any of the wireless communication terminals managed by the network station, the network station changes the frame scheduling information currently assigned to the wireless communication terminal being the transmission source of the notification indicating that the radio wave interference is detected.
