摘要
无线IP用户需要获得跟固定Internet用户一样的业务以及QOS。针对3GPP2的ALL-IP网络体系结构,采用次和缓存的机制,利用邻居单播、前向转发和后向转发三种单播转发机制,取得无线IP网络的平滑切换。仿真结果表明笔者提出的邻居单播机制性能最好,可以保证业务QOS。
Wireless IP users need to acquire the same traffics as fixed Internet users and QOS.On the base of3GPP2ALL-IP network architecture,adopts hierarchy and cache mechanisms ,and uses three unicast forwarding mechanisms ,that is,neighbor unicast,forwards forwarding and backwards forwarding,to acquire smooth handoff in wireless IP network.Simulation shows that the performance of the neighbor unicast mechanism is superior,which can guarantee traffics QOS.
