METHOD, SYSTEM AND APPARATUS FOR PROTECTING AGENT MOBILE INTERNET PROTOCOL SIGNALING

摘要

Two methods for protecting PMIP signaling are provided. The first is that the centralized controlling node or the mobile IP agent generates SPI for uniquely identifying the shared key, or triggered by the IP agent and the home agent HA generates SPI for uniquely identifying the shared key. Four systems for protecting the PMIP signaling are also provided. The four systems respectively realize the method for generating SPI for uniquely identifying the shared key, the SPI was generated respectively by the centralized controlling node, by the mobile IP agent and by the HA. A mobile IP agent, a centralized controlling node and a home agent which can generate SPI for uniquely identifying the shared key are also provided. Another mobile IP agent for triggering the home agent to generate the SPI for uniquely identifying the shared key is also provided. The solutions of the method, system and apparatus are to perfect the protection mechanism of the PMIP signaling.
