1. A method for operating a wireless device during a radio connection loss, the method comprising:
establishing that a cause of the radio connection loss corresponds to an outage of a radio cell hosting the wireless device, establishing the cause of the radio connection loss based on information relating to the quality of the radio connection before said radio connection loss, whereby the wireless device establishes that the cause of the radio connection loss corresponds to an outage of a radio cell if the quality fulfills a pre-determined condition; and
determining, based at least on the established cause, a policy of applying a random time delay when transmitting a request to a radio network node in a target radio cell.
