A first user device may communicate discovery packets in search of other user devices to which the first user device may connect. The first user device may identify a second user device (as a result of sending the discover packets). The first and second user devices may obtain configuration parameters (e.g., a communication channel allocation, encryption keys, synchronization information, etc.) and may establish a D2D connection based on the configuration parameters. The D2D connection may enable the first and second user devices to communicate with another as though the user devices were connected to a wireless telecommunications network (e.g., via telephone calls, video calls, simple messaging services (SMS) messages, instant messages, etc.)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Offline user device communications","description":"Techniques described herein may be used to enable a user device (e.g., a smartphone, a tablet computer, etc.) to access network services without having to be connected to a network (e.g., a wireless t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9736877","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.
