A terminal device and method of re-establishes a circuit switched call or a packet switched connection in a data network having at least a first access network and a second access network. A failure of the circuit switched call or the packet switched connection established via the first access network is detected at the terminal device and connection re-establishment is initiated via the second access network in response to the result of checking registration to the second access network, if a failure has been detected. Thereby, a new option is provided to avoid connection failures when coverage to another access network is available, especially where call re-establishment via the first access network is not allowed.
