Configuring Support to Indicate IMS VoPS Support

To configure the support that allows AMF to flag if UE supports the IMS VoPS, use the following configuration:

config 
   amf-global 
     call-control-policy policy_name 
       feature-support-ie 
         ims-vops-service-3gpp 
            supported { false | true } 
               ue-capability-match-required { false | true } 
               reject-voice-centric-ue  { false | true } 
               end 

NOTES:

  • feature-support-ie —Configure the AMF or 5GC features that are supported or unsupported.

  • ims-vops-service-3gpp —Configure the UE support for the IMS VoPS service over 3GPP access.

  • supported { false | true } —Enable the 5G VoPS 3GPP. If the UE capability is supported, the UE is configured with the UE Radio capability.

  • ue-capability-match-required { false | true } —Configure the UE Radio capability based on the requirement match criteria.

  • reject-voice-centric-ue { false | true } —Configure the UE capability to reject the “voice centric” UEs when the IMS VoPS service is not supported.

    Any change to the reject-voice-centric-ue CLI takes an effect only on the new subscriber (new Registration Requests) or when ueUssageSetting is changed from Data Centric to Voice Centric or conversely. Modifications to reject-voice-centric-ue do not have an impact on the ongoing calls.
