The method also includes triggering, using the at least one processor, a partial call setup from a first SIM card of the multiple SIM cards to a second SIM card of the multiple SIM cards. The method further includes determining, using the at least one processor, whether the electronic device receives the partial call setup. In addition, the method includes, in response to determining that the electronic device receives the partial call setup, setting, using the at least one processor, the NAT keep-alive interval for each of the multiple SIM cards to be equal to the maximum NAT interval."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Real-time lightweight NAT keep-alive interval optimization for multi-SIM mobile devices","description":"A method includes setting, using at least one processor of an electronic device that includes multiple subscriber identity module (SIM) cards, a maximum Network Address Translation (NAT) interval to b","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11290866","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.
