The SMF receives, by from the CHF, a response message comprising the charging policy information for the PDU session. The charging policy information comprises: a first charging method; and an information element indicating that a first charging rate is applicable for the PDU session. The SMF determines, based on the charging policy information, a charging control rule for the PDU session. The SMF enforces the charging control rule."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Charging policy information for a packet data unit session in a wireless network","description":"A session management function (SMF) sends to a charging function (CHF), a charging policy request message requesting charging policy information for a packet data unit (PDU) session of a wireless devi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11533401","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.
