针对IEEE802.16中继网络链路层切换所需信令交互较多,将快速移动IPv6协议使用在IEEE802.16中继网络中将引起更大的信令开销和处理时延的问题,提出适用于IEEE802.16中继网络的快速移动IPv6切换解决方案,通过底层信息的交互提前进行跨子网切换的判断,以减少底层信息的交互,加快网络层切换的速度.仿真结果表明,新方案可减小系统切换的信令开销和切换时延.
In order to exchange the signaling interaction needed for the link layer switching in the IEEE802.16 relay network, the problem that the fast moving IPv6 protocol will cause greater signaling overhead and processing delay in using the IEEE802.16 relay network is proposed In IEEE802.16 relay network fast mobile IPv6 switching solution, through the interaction of the underlying information in advance to make cross-subnet switch judge, in order to reduce the interaction of the underlying information to speed up the switching speed of the network layer.The simulation results show that the new program can Reduce the system switching signaling overhead and switching delay.
