Abstract
Systems and methods are provided for improving the overall experience for users conducting voice calls over 5G. For example, failing to establish a Transport Control Protocol (TCP) connection to a Proxy-Call Session Control Function (P-CSCF) server leads to user equipment (UE) not registering to an Internet Protocol Multimedia Subsystem (IMS), and impacts the 5G voice call. A voice call flow handling function on the UE performs several handling procedures to dynamically adjust the flow to address failed connections to the P-CSCF server. After initiating a 5G voice call, the UE can detect a failed connection to the P-CSCF server. In response, a secondary P-CSCF server from a plurality of available P-CSCF servers is selected. A connection to the selected secondary P-CSCF server is attempted. A successful connection to the selected secondary P-CSCF server supports the UE registering to the IMS to conduct the voice call over 5G New Radio (NR).
