Method and system for supporting mobility security in the next generation network

摘要

The present invention discloses a method and system for supporting mobility security in a next generation network. In implementation of the method, a Transport Authentication and Authorization Functional Entity (TAA-FE) and a mobile agent functional entity are configured in the network, and a reference point for transmitting key material is established between the TAA-FE and the mobile agent functional entity; when a terminal moves, the mobile agent functional entity receives the key material from the TAA-FE, and performs security protection for signaling between the terminal and the mobile agent functional entity. The system comprises: a transport user profile functional entity, a TAA-FE, and a mobile agent functional entity. Applying the present invention, the mobility security on the transport layer in the next generation network is ensured.
