Abstract: In conventional mobile Ipv6 handover schemes, each and every handover operation requires a large number of interactive signalings, thus increasing the time delay. Based on the architecture for fast mobile hierarchical MIPv6, a new QoS context transfer solution is proposed to ensure the QoS of real-time applications when using mobile node to perform the handover. It shortens the delay caused by the time taken from QoS resignaling to QoS retransmission after handing over the mobile node, thus reducing the possibility of interruption of talk through mobile node. Theoretic analyses and simulations showed that the proposed scheme can obviously decrease the delay and jitter in real-time handover operation, especially in the frequent ping-pong handover operation. Smooth handover of mobile node is therefore available.
