Method and device for selecting and managing mobility protocol in mobile communications system

The present invention relates to a mobility protocol selection and management between the network and the terminal in a mobile communication system, the mobile station number at the time of mobility protocols set the IP tunnel (setup) to a network and transmitting and receiving data to support, the first terminal supports the possible mobility protocol list and / or preference information to send (for example, information about the mobility protocol with which the terminal is preferred), and the second network that determines the mobility protocol of the IP tunnel to send and receive the terminal and the data on the basis of the information (selection) so, to improve the resource efficiency at the time of the terminal and the IP tunnel created between the network.
