Abstract:
A method and system for circuit-switched fallback (CSFB) is disclosed. A first wireless network may receive from a wireless communication device (WCD) a report including an indication of radio frequency (RF) quality of a second wireless network. The first wireless network may make a determination of whether the reported indication of RF quality exceeds a threshold. If the determination is that the reported indication of RF quality exceeds the threshold, the first wireless network may send the reported indication of RF quality to the second wireless network. However, if the determination is that the reported indication of RF quality does not exceed the threshold, the first wireless network may direct the WCD to hand off to the second wireless network and refrain from sending the reported indication of RF quality to the second wireless network.
