  • Patent number: 8300631
    Abstract: A method for realizing mobile IP management includes: a mobile node (MN) sends a mobility registration signal to a mobility control (MC) entity in a control function entity of the transmission layer of the network; a home mobility control entity of the mobile node registers the mobile node, returns a registration response to the mobile node and transmits a control signal to a mobility forwarding (MF) entity in the transmission layer; the mobility control entity controls the mobility forwarding entity to provide communication services for the mobile node after it receives a request signal from the registered mobile node. A method for realizing mobile IP management in NGN network and a network system for realizing mobile IP management are also disclosed.
