Abstract: Facilitating conditional fast return to stand alone advanced networks after voice fall back with network congestion awareness is provided herein. Operations of a system can include controlling a first communication for a user equipment based on a connection request that comprises an indication of a fall back procedure. The operations can also include, based on a determination that the first communication has completed at the user equipment, releasing a first control of the user equipment. Further, the operations can include delaying a redirection of the user equipment to the network equipment for a second control of a second communication scheduled to occur at the user equipment. Delaying of the redirection is based on a determined network congestion level applicable to the communication network being determined to be at most a defined network congestion level.
