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 (2 nd generation)/3G (3 rd generation) 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.

Abstract translation: 本公开的某些方面涉及用于改善电路交换回退（CSFB）用户体验的技术。 在方面中，提供了用于将用户设备（UE）从2G（第二代）/ 3G（第三代）网络自主地返回到LTE（长期演进）网络的方法和系统。 UE可以存储标志以注意2G / 3G网络中的当前电路交换（CS）呼叫是否是CSFB的结果。 UE响应于检测2G / 3G网络中当前CS呼叫的终止并确定终止的呼叫是CSFB呼叫（例如，从标志的状态），可以触发移动机制以自主地返回 UE到LTE网络。
