Abstract
Disclosed is a method and corresponding system for managing CSFB pre-registration. A first network serving a UE releases the UE from being served by the first network and redirects the UE to transition from being served by the first network to being served by a second network. The first network then detects that the UE has returned to be served by the first network. In response to detecting the return of the UE, and based on the previous releasing and redirecting of the UE, the first network then initiates a pre-registration of the UE with the second network to inform the second network that the UE is now reachable via the first network.
