  • NON-NETWORK-SLICING-BASED CONFIGURATION METHOD, DEVICE AND NON-TRANSITORY COMPUTER-READABLE MEDIA
    Publication number: 20250175892
    Abstract: A non-network-slicing-based configuration method is provided. The method includes generating, by a next-generation radio access network (NG-RAN) node, a next-generation setup request message, wherein the next-generation setup request message does not include a first network slice support list supported by the NG-RAN node. The method includes transmitting, by the NG-RAN node, the next-generation setup request message to an access and mobility management function (AMF) node in a core network.
