Mobile communications devices and methods for inter-radio access technology performance enhancement
A method for inter-radio access technology (inter-RAT) performance enhancement in a mobile communications device is provided. First, a first RAT is camped on to perform a first service. Thereafter, it is moved/fallen back to a second RAT from the first RAT to perform a second service. Cell information of the first RAT is then measured and collected during the performance of the second service in the second RAT. A first cell to return to the first RAT is determined according to the collected cell information of the first RAT after a call connection of the second RAT is released.
