Network function sizing utility for IMS Core (3GPP TS 23.228), calculating P-CSCF, S-CSCF, I-CSCF, and HSS capacity for VoLTE and VoNR subscriber populations.
The dimensioner maps subscriber behavior (registration interval, BHCA, call hold time) to SIP transaction rates per IMS function, applying standard oversubscription and redundancy models.
Built on 3GPP Technical Specifications, ensuring accuracy for production deployments and security audits.
Calculations specifically designed to identify protocol vulnerabilities and signaling misconfigurations.
Compliant with 3GPP TS 23.228 IMS architecture. Critical for VoLTE launch planning and VoNR 5G SA core upgrades where IMS must scale to carry all mobile voice traffic.
