A Java-based offline charging application can be deployed on the SIP server engine tier in order to allow the SIP server to generate offline charging events and transmit them to a charging data function (CDF) server. The state data for the offline accounting session can be maintained on the state tier. Furthermore, timers set to accounting interim interval value can be used to indicate expiration times for the accounting session. The SIP server can use the timers to send periodic interim requests in order to update and maintain the accounting session open."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for a SIP server with offline charging","description":"The SIP server can be comprised of an engine tier that is designed for high throughput processing of SIP communications and a state tier that maintains state information for access by the engine tier.","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9667430","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.
