Method to operate a wireless device in a wireless cellular network for inter-Radio Access Technology selection, the wireless device comprising a communication unit, and at least one storage element, the wireless cellular network comprising at least two radio access networks (8.1, 8.2), the communication unit being configured to communicate to a network node (7.1) being part of the wireless cellular network, the network node (7.1) being associated to a first radio access network (8.1), the method comprising the steps for the communication unit of: - detecting if a second radio access network (8.2) of said wireless cellular network fulfils characteristics being defined by a predefined set of access parameters, wherein said set of access parameters comprises the requirement that the second radio access network (8.2) is available, - wherein the second radio access network (8.2) supports a different access technology than the first radio access network (8.1), - if the detection step indicates that said second radio access network (8.2) fulfils said characteristics: - sending a connection release indication to the network node (7.1), - receiving from the network node (7.1) a connection release confirmation message, - sending a connection request message to the wireless cellular network with selection of said second radio access network (8.2), further comprising storing measurements indicating the availability of the second radio access network (8.2) at an earlier point in time, wherein said availability of the second radio access network (8.2) is determined by accessing said stored previous measurements, wherein, if the detection step indicates that no second radio access network (8.2) fulfils said characteristics, the method further comprises the steps of: - starting a timer, - measuring a first indication of the current location, - after expiry of timer measuring a second indication of the current location, - if the first and second indication of the current location materially differ, - repeating the detection step, - otherwise restarting the timer. the wireless device comprising a communication unit, and at least one storage element, the wireless cellular network comprising at least two radio access networks (8.1, 8.2), the communication unit being configured to communicate to a network node (7.1) being part of the wireless cellular network, the network node (7.1) being associated to a first radio access network (8.1), the method comprising the steps for the communication unit of: -
