END-TO-END ARCHITECTURE, API FRAMEWORK, DISCOVERY, AND ACCESS IN A VIRTUALIZED NETWORK

摘要

Systems, methods, and instrumentalities are disclosed such that a network (e.g., a radio access network, RAN, node) may provide a wireless transmit/receive unit (WTRU) with a service-based network access for a new service. The RAN node may comprise a receiver, a transmitter, and a processor operatively coupled to the receiver and the transmitter. The receiver may be configured to receive a request message from the WTRU. The request message may indicate service-based network access information. The processor may be configured to select a service node belonging to a core network based on information in the request message. The transmitter may be configured to send a response message to the WTRU. The response message may indicate accepted service-based network access information, wherein the accepted service-based network access information is associated with at least one public land mobile network (PLMN) identifier (ID).
