Abstract
Facilitating fast return to stand alone advanced networks (e.g., 5G, 6G, and beyond) after voice fall back is provided herein. Operations of a method can comprise receiving, from a first network device and by a second network device, a connection request that comprises an indication of a fall back procedure. The fall back procedure can be an “RRC release and redirect” or an “IRAT Handover.” The method also can comprise facilitating control of the voice communication for the mobile device and triggering a release of the control of the mobile device from the second network device based on a determination that the voice communication has completed. The fast return procedure can be either a “RRC release and redirect’ or an “IRAT handover.” Further, the method can comprise redirecting the mobile device to a third network device selected based on a capability of the mobile device.
