Network fallback and fast return

Abstract:

A method may include establishing a Fifth Generation (5G) a network connection with a user equipment (UE) device and receiving, by a 5G wireless station, information associated with handling voice communication sessions for the UE device. The method may also include receiving information, from the UE device or directed to the UE device, associated with a first voice communication session, signaling a Fourth Generation (4G) wireless station to establish a connection to the UE device, in response to receiving the information associated with the first voice communication session and establishing, by the 4G wireless station, a connection to the UE device. The method may further include conducting the first voice communication session over a 4G network, determining whether the first voice communication session has terminated and determining whether to reconnect to the 5G network, in response to determining that the first voice communication session has terminated.
