摘要

Being execution method of the hand off which is adapted to QoS in between the 1st and 2nd channel where this invention the Mobile node (MN) with ahead communicating the node (CN) with is based on IP between, is based on especially Mobile IPv6, 2nd channel not to have relay station or the Mobile node to be one of the plural channels which are accessible or with the relay station of one or more, at the same time at least,a) as a 2nd channel the Mobile node the step which selects one channel from the plural channels which are accessible,The smallest service quality request regarding the channel which one which is allotted to the Mobile node b) on the basis of the channel which is selected IP address is selected at least (QoS) with the message which is included (BU) the step which occurs due to the Mobile node,c) the message approximately phase doing in the communication sutra road surface which is selected, the step which inspects the smallest service quality request at least depending upon the individual relay station which is passed and/or ahead communicating with the node, depending upon when it guarantees,It regards the execution method of the hand off which is adapted to QoS which it possesses. Message ahead communicating communication to the node and/or includes the smallest service quality demand for communication of the opposite direction from the Mobile node, is done with the channel which automatically hand off is selected to the case where the smallest service quality request is satisfied at least 1st channel and as 2nd channel or when or satisfactory characteristic of the smallest service quality request is not given at least, message is stopped, information occurs relay station and/or ahead communicating in the node and is sent to the Mobile node.
