Abstract: A method performed by a first base station associated with a preferred access network includes initiating a first handover of a wireless device to a second base station associated with a non-preferred access network in response to fulfillment of a condition. Information indicating that the wireless device is subject to a forced access change is transmitted to a second base station associated with the non-preferred access network. The information also indicates that a second handover of the wireless device should be initiated to hand the wireless device back to the first base station or another base station associated with the preferred access network as soon as the condition is no longer fulfilled.
