Claim 23:
24. A core network node for a visited cellular network of a wireless device for accepting or rejecting a handover of the wireless device from an incoming access network to a cellular access network of the visited cellular network while the wireless device is in roaming, the core network node comprising processing circuitry operable to cause the core network node to:
receive a message that is related to a handover of a wireless device from an incoming access network to a cellular access network of the visited cellular network, wherein the message comprises an incoming access indication wherein the incoming access indication is an indication of the incoming access network from which the handover of the wireless device is desired;
make a decision as to whether to accept or reject the handover based on the incoming access indication, wherein make a decision as to whether to accept or reject the handover based on the incoming access indication comprises deciding to reject the handover based on the incoming access information;
upon deciding to reject the handover, reject the handover using a code that indicates that the handover failed due to a non-allowed incoming access network; and
send a message to the wireless device that indicates that the handover is rejected, the message comprising the code that indicates that the handover failed due to a non-allowed incoming access network.
