US 11,689,580 B1 · Use of alternate VoIP call-placement service in response to IMS processing failure

Abstract

A method and system for responding to a processing failure of an Internet Protocol (IP) Multimedia Subsystem (IMS). An example method includes a computing system detecting the processing failure of the IMS and responsively causing one or more user equipment devices (UEs) to forgo using the IMS for voice over IP (VoIP) call placement and to instead use an alternate VoIP calling service for VoIP call placement. For instance, a given UE may be configured by default to use the IMS for VoIP call placement, but the UE may detect an IMS processing failure and may responsively instead make a next VoIP call placement attempt using an alternate VoIP calling service, such as a third party VoIP calling application running on the UE.

Dependent claims

A method for responding to a processing failure of an Internet Protocol (IP) Multimedia Subsystem (IMS), the method comprising:

detecting, by a computing system, the processing failure of the IMS, wherein detecting the processing failure of the IMS comprises detecting a signaling overload of the IMS, wherein detecting the signaling overload of the IMS comprises detecting that at least predefined threshold many UEs per unit time have transmitted at least predefined threshold many IMS signaling messages per unit time;
and
responsive to at least the detecting of the processing failure of the IMS, causing, by the computing system, one or more user equipment devices (UEs) to forgo using the IMS for voice over IP (VoIP) call placement, wherein each of the one or more UEs would instead use an alternate VoIP calling service for VoIP call placement.
