Method and system for circuit-switched fallback

摘要

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.

主权项

1. A method comprising:
a first wireless network receiving from a wireless communication device a report including an indication of radio frequency (RF) quality of a second wireless network; the first wireless network making a determination of whether the reported indication of RF quality exceeds a threshold; and (i) if the determination is that the reported indication of RF quality exceeds the threshold, the first wireless network sending the reported indication of RF quality to the second wireless network, whereby the second wireless network then assigns an air-interface traffic channel for the wireless communication device and the wireless communication device hands off from the first wireless network to the second wireless network, but (ii) if the determination is that the reported indication of RF quality does not exceed the threshold, the first wireless network directing the wireless communication device to hand off to the second wireless network and the first wireless network refraining from sending the reported indication of RF quality to the second wireless network.
