One or more of these network elements are pre-loaded with a local database copy of the user profiles as typically contained in the HSS inside of the IMS control structures. A master database, such as the one typically contained in the HSS, is distributed to all network elements using database distribution methods. Advantageously, pre-authentication solves bottleneck issues in the SIP mechanism by allowing an end user device to use fully authenticated SIP requests. This prevents the requirement to perform authentication, authorization, and accounting (AAA) all the way back to the core IMS network, alleviating lag and scaling issues. Additionally, network elements including can become aware of the services requested through SIP requests, and track these requests for optimization. Specifically, resources requested based upon SIP requests can be cached."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and systems for distributed authentication and caching for internet protocol multimedia subsystem and other session initiation protocol systems","description":"Network elements in IMS or other SIP systems are configured to pre-authenticate SIP requests either as proxy or by snooping.
