The IMS receives a Session Initiation Protocol (SIP) Invite message for the media session to the UE and responsively transfers a status request for delivery to the LTE network serving the UE. The LTE network identifies a status of an LTE base station serving the UE and identifying an alternative communication network serving the UE. The LTE network determines that the media session should be redirected to the alternative communication network based on the status of the LTE base station and the identified alternative communication network serving the UE. The LTE network transfers a status response for delivery to the IMS indicating media session redirection to the alternative communication network. The IMS then transfers the SIP Invite message for the media session to the UE for delivery to the alternative communication network serving the UE."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data communication system redirection of a media session to user equipment","description":"An Internet Multimedia Subsystem (IMS) identifies a Long Term Evolution (LTE) network serving the UE.
