The method includes determining when a member starts a switching action from one service to another. A time dependent quantity starting from the switching action is determined. The method includes determining that the member is a member of a switching group when the quantity is less than a threshold value is made, and when the quantity is larger than the threshold, determining that the member has decided to join a new group, and changing the appropriate access key(s)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and an apparatus for key management in a communication network","description":"A method of key management in a communication network that includes a plurality of groups with each group including one or several members authorized to have access to key-protected services is provid","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8515064","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.
