Abstract

A system, method, and computer program product are provided for smart inter-Radio Access Technology (IRAT) Voice over Long-Term Evolution (VoLTE) mobility. In operation, a serving cell receives an indication of poor coverage from user equipment (UE) during an active call. The serving cell determines to initiate an inter-Radio Access Technology (IRAT) handover process if the coverage for the UE has become worse than a threshold value. The serving cell identifies at least one parameter (e.g. CovTriggerdBlindHoAllowed) indicating a conditional state in which selection between a measurement-based handover and a blind-based handover for the IRAT handover process is based on a critical condition threshold. The serving cell selects between the measurement-based handover and the blind-based handover for the IRAT handover process, as a result of identifying the conditional state of the parameter.
