Abstract
Systems, methods, and software for handling circuit switch fallback (CSFB) communications are provided herein. A method of operating a wireless communication system is provided, where a wireless communication device is initially configured to use CSFB services over a first wireless communication network. The method includes detecting CSFB failure by at least monitoring performance of a CSBF link between the first wireless communication network and a second wireless communication network that routes voice call signaling over the CSBF link for at least the wireless communication device, and responsive to the CSFB failure, informing at least the wireless communication device of the CSFB failure and routing further voice call signaling for the wireless communication device using the second wireless communication network instead of the CSFB link.
