Abstract
A method is provided for handling a voice call in a heterogeneous network environment by a wireless device. The method includes sending a registration request to a network node in a Next Generation (5G) network. The wireless device has an existing voice call on a different network in the heterogeneous network environment. The method further includes receiving a registration acceptance from the network node in the 5G network. The registration acceptance indicates that IMS voice services are supported, but existing voice calls are not supported. The method further includes determining to stop an attempt to move the existing voice call to the 5G network.
