Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish a first wireless connection associated with a first subscription using a first radio access technology, and may establish a second wireless connection associated with a second subscription using a second radio access technology. The UE may perform a call over the second wireless connection, and identify a loss of the first wireless connection based on performing the call over the second wireless connection. The UE may perform a network discovery procedure associated with the first subscription using the first radio access technology based on the loss of the first wireless connection and a termination of the call over the second wireless connection.

Abstract: Embodiments include systems and methods for enabling fast recovery by a user equipment (UE) from packet switched (PS) call failure in a fifth generation (5G) non-standalone (NSA) network. Various embodiments for recovering from PS call failure in a 5G NSA network may include determining whether a total number of Evolved Packet System (EPS) bearer deactivation requests received from a base station of a 5G NSA network during a time period exceeds a maximum counter value, and disabling 5G data calls on the UE in response to determining that the total number of EPS bearer deactivation requests received from the base station of the 5G NSA network during the time period exceeds the maximum counter value.
