Abstract: Fall back using mobile device assisted terminating access domain selection is provided. A network entity forwards an invitation to a session to a mobile device. Session has packet switched bearers for media. Mobile device replies with a rejection of the invitation and a request for network entity to hold the session. Rejection is based on mobile device determining circuit switched bearers should be utilized. Mobile device sends a circuit switched call and network entity correlates the circuit switched call with the session. A dialog is set up over circuit switched domain bearers and Internet Protocol Multimedia Subsystem bearers.
