Abstract

Certain aspects of the present disclosure relate to techniques for improving a circuit-switched fallback (CSFB) user experience. In aspects, methods and systems for autonomously returning a user equipment (UE) from a 2G (2generation)/3G (3generation) network to an LTE (Long Term Evolution) network are provided. The UE may store a flag to note whether a current circuit switched (CS) call in the 2G/3G network is a result of a CSFB. The UE, in response to detecting a termination of the current CS call in the 2G/3G network and determining that the terminated call was a CSFB call (e.g., from the status of the flag), may trigger a mobility mechanism to autonomously return the UE to the LTE network.
