The Application of  PSC-CEA in the Process of Resource Allocation Dynamic Policy Triggering during the Switchover of Mobile IP

摘要

This paper demonstrates the necessity of the use of PSC-CEA for dynamic policy triggering in the process of mobile IP switching; in the mean time, according to the characteristics of policy based network management, propose a dynamic policy trigger model, and designs a mechanism which is used to update dynamic policy according to known information, experience and knowledge to satisfy the QoS of mobile services and use current network resource sufficiently.
