Abstract
Systems and methods described herein bring a 5G standalone-capable end device back into 5G service to leverage the 5G network's data capacity as soon as a VoLTE call is over. A network device receives a fallback connection, for a 5G New Radio (NR) standalone-capable end device, from a second network to the first network to support a voice call on the end device, wherein the fallback connection supports a voice-over-LTE call. The network device detects an end of the VoLTE call and initiates, in response to the detecting, a handover of the end device back to the second network, wherein the initiating occurs while the end device is in a radio resource control (RRC) connected mode.
