Abstract:
Systems and methods are disclosed herein for performing a controlled handover of a wireless device from an incoming access network to a cellular access network of a visited cellular network. In some embodiments, a method for handover of a wireless device from an incoming access network to a cellular access network of a visited cellular network while in roaming comprises, at the wireless device, sending a message to a core network of the visited cellular network. The message is related to a handover of the wireless device from the incoming access network to the cellular access network of the visited cellular network and comprises an incoming access indication. The incoming access indication is an indication of the incoming access network. The method further comprises, at the core network node, receiving the message and making a decision for the handover based on the incoming access indication.
