Abstract
A multi-RAT capable wireless device and a method for execution in a multi-RAT capable wireless device are provided. The wireless device maintains a registration history of all wireless network,RAT combinations through which the wireless device has previously attempted to register with data communication service registration point. Upon an event triggering network registration, the wireless device identifies a set of available wireless network,RAT combinations, selects an available wireless network,RAT combination from the set of available wireless network,RAT combinations having regard to the registration history and a preferred network,RAT combination list stored at the wireless device and attempts to register with the data communication service registration point through the available wireless network,RAT combination that has been selected. If the attempt is successful, the wireless device receives an update to the preferred network,RAT combination list and updates the preferred network,RAT combination list stored at the wireless device.
