  • Patent number: 11871327
    Abstract: The present invention relates to a terminal device and a method by which a terminal device switches a data transmission path, the terminal device being capable of switching a data transmission path by determining by itself whether the data transmission path for transmission of user plane data is switched without a link, among core configurations of respective networks in a mutual interworking environment among heterogeneous networks.
