The method includes routing a first Invite request for the communication session via a media path extending from the first Visited IMS network via a Home IMS network of the called subscriber to the second Visited IMS network, and establishing the communication session. The method further includes inserting an additional IMS network entity, residing in the second Visited IMS network, in the part of the media path extending from the first Visited IMS network to the Home IMS network of the called subscriber and removing the Home IMS network of the called subscriber from the media path."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, network and network entity for establishing a communication session to a user equipment roaming in IMS","description":"The invention relates to a method, network ad network entity for establishing a communication session between a calling subscriber residing in a first Visited IMS network and a called subscriber roami","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9794302","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.
