摘要：A method is disclosed to help register a UE with a different network in theevent of an unsuccessful registration with a fallback network. In accordance with the
disclosure, a UE may be registered on a first network and may then seek to register witha second network via the first network. The first network may attempt to register the UEwith the second network, but the attempt to register the UE with the second networkmay ultimately fail. In response to such failure, the first network may discontinueproviding service to the UE. Discontinuing the providing of service to the UE on the firstnetwork may result in the UE seeking to register directly with the second network or witha different network. By registering directly with the second network, or a differentnetwork, the UE may be able to initiate and/or receive voice calls via that network.
