In an embodiment, the media call data and signaling are split such that the data is transported over the WLAN and the signaling is transported over the cellular network. In another embodiment, handover latency is reduced by using a dual registration process that registers the UE with an IMS server using both a WLAN-based contact and a cellular network-based contact. The media call can then be carried over the WLAN and/or the cellular network and can be handed over seamlessly from one to the other within minimal signaling."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Low latency IMS-based media handoff between a cellular network and a WLAN","description":"Methods for transporting a media call between an IMS server and a User Equipment (UE) and of handing over the media call between a cellular network and a WLAN are provided.
