Abstract
A disclosed method may include transmitting, by a UDM function based on determining that a network interworking support database contains VLR information for a UE associated with a legacy network, a deregistration request to a Home Location Register (HLR) of a mobile network such that an HLR clears the VLR information of the UE from the network interworking support database and sends a cancellation message to a VLR of a legacy network to remove registration information for the UE such that the mobile network avoids redirecting a call for the UE to the legacy network after the UE has returned to a coverage area of the mobile network after roaming in a coverage area of the legacy network.
