The instructions are executed by the at least one processor to receive a policy request of a first user sent by a gateway device; determine, according to the policy request, that the first user needs to use a counter of a second user; acquire a current status of the counter of the second user using a session of the second user established between the PCRF device and a charging system; and generate a control policy of the first user according to the current status of the counter of the second user and send the control policy to the gateway device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Policy decision method, charging device, and system","description":"A policy and charging rules function (PCRF) device includes a memory storage comprising instructions, at least one network interface, and at least one processor coupled to the memory and to the at lea","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9794420","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.
