Dynamic switching of voice services in packet switching networks

A system for providing a voice call for a user equipment (UE) over a wireless network, the system comprising:

• a processor;
• and
• a computer-readable medium storing instructions that are operative upon execution by the processor to:
• monitor, by a voice service control, voice call key performance indicators (KPIs) for the voice call of the UE, when the voice call comprises a voice over new radio (VoNR) call;
• determine, by the voice service control, that the voice call KPIs do not meet acceptable performance criteria;
• determine, by the voice service control, that an eNodeB (eNB) is co-located with a gNodeB (gNB) that is serving the UE;
• and
• based on at least determining that the voice call KPIs do not meet acceptable performance criteria, and determining that an eNB is co-located with the serving gNB, instruct, by the voice service control, a radio access network (RAN) to begin an inter-radio access technology (IRAT) handover (HO) for the UE to the co-located eNB.

One or more computer storage devices having computer-executable instructions stored thereon, which, upon execution by a computer, cause the computer to perform operations comprising:

• monitoring, by a voice service control, voice call key performance indicators (KPIs) for a voice call of a user equipment (UE), when the voice call comprises a voice over new radio (VoNR) call;
• determining, by the voice service control, that the voice call KPIs do not meet acceptable performance criteria;
• determining, by the voice service control, that an eNodeB (eNB) is co-located with a gNodeB (gNB) that is serving the UE;
• and
• based on at least determining that the voice call KPIs do not meet acceptable performance criteria, and determining that an eNB is co-located with the serving gNB, instructing, by the voice service control, a radio access network (RAN) to begin an inter-radio access technology (IRAT) handover (HO) for the UE to the co-located eNB.
