New method of L2-Trigger based on the Handoff of mobile communication systems
基于移动通信切换特性的L2-Trigger方法

In order to satisfy real-time applications, L2-Trigger has been proposed to trigger layer 3 handoff ahead to decrease the handoff delay of mobile IP. But some problems such as misty indications and ambiguous trigger techniques have been found in former methods. A new L2-Trigger method and a routes updating protocol named Double Routes Pre-Registration were put forward. This method will eliminate the registration delay when Mobile Node (MN) moves from one network to another.
