A mobile device with Internet access can operate a software program to communicate with a corresponding node. The corresponding node may access the Internet through either a NAT router or a firewall. The mobile device establishes a media session with a corresponding node via the transmission of a first media stream and receipt of a second media stream, and a media control channel can optionally be implemented. The mobile device acquires Internet access through a second IP address, and packets routed between the second IP address and the Internet may traverse a NAT router. The mobile device evaluates the type of NAT at the second IP address from a stored LAN profile. A software routine determines that handover of the media session from the first IP address to the second IP address is preferred."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Efficient handover of media communications in heterogeneous IP networks using LAN profiles and network handover rules","description":"Methods and systems are provided for efficient handover of a media session between heterogeneous IP networks.
