The method includes receiving, by a terminal from a control plane function entity, corresponding network slice information used for transferring an established PDN connection to a 5G network, where the corresponding network slice information includes corresponding single network slice selection assistance information (S-NSSAI). The method further includes sending a packet data unit (PDU) session establishment request, where the PDU session establishment request includes corresponding S-NSSAI used for transferring a first PDN connection to the 5G network and a corresponding data network name (DNN) used for transferring the first PDN connection to the 5G network, and the first PDN connection is any one of one or more established PDN connections."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Session establishment method and apparatus","description":"A session establishment method and an apparatus, such that an established packet data network (PDN) connection is transferred to a network slice in a fifth generation (5G) network during inter-system ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11533375","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
