Abstract
A wireless communication device (WCD) transmits to a first serving system a data-connection request that requests a packet data connection. A mobility management entity (MME) determines that an authentication procedure for authenticating the WCD for the requested packet data connection is unavailable. In response, the MME initiates a handover of the WCD from the first serving system to a second serving system. The first and second serving systems use different air interface protocols. When the handover has been successfully completed, the MME stores an indication that the WCD has been diverted to the second serving system. The MME may subsequently determine that the authentication procedure has become available. In response, the MME determines whether the WCD is associated with a valid subscriber profile. If so, the MME requests the second serving system to invite the WCD to connect to the first serving system.
