A network forwards towards a callee an invitation for a call originating via a first Radio Access Technology (RAT) from the mobile device, and forwards a response of the callee via the first RAT towards the mobile device. The response indicates a change of the call state from a first state to a second state. A first network component changes via a second RAT the call state of the mobile device when receiving information indicative of the first state followed by receiving a message indicative of the second state. A second network component receives from the first network component an invitation for a transfer of the call of mobile device from the first RAT to the second RAT."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Technique for transferring a session with changeable session state","description":"A technique for triggering a change of a call state of a mobile device is presented.
