The first mobile radio then detects, via a short-range wireless communication interface, a second mobile radio, and authenticates, the second mobile radio using the talkgroup-specific security token. If the authentication is successful, the first mobile radio adds an identity of the second mobile radio to a sub-talkgroup set of mobile radios of the first talkgroup."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and systems for joining a sub-talkgroup of a first talkgroup","description":"A process carried out by a first mobile radio for joining a sub-talkgroup of a first talkgroup includes receiving, via a provisioning process or via an infrastructure wireless communication interface ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9750059","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.
