Abstract:
Methods and apparatus are provided for EPS fallback status report by the modem to the upper layers. In one embodiment, the mobile terminal (MT) initiates a 5G voice call, detects an EPSFB triggered by the wireless network, identifies one or more EPSFB status and sends one or more EPSFB status indicators to at least one upper layer based on the identified one or more EPSFB status. In one embodiment, the EPS fall back is a redirection procedure. In another embodiment, the EPS fallback is a handover procedure. In yet another embodiment, the one or more EPSFB status indictors comprising a redirection to EPS started indicator, a handover to EPS started indicator, a redirection to EPS failed indicator, a handover to EPS failed indicator, a redirection to EPS success indicator, and a handover to EPS success indicator. In one embodiment, the MT sends EPSFB status indicators using AT command.
