Conformance Testing

Conformance testing verifies that equipment or software implements a standard correctly, for example, a UE conforming to 3GPP NAS specifications, or a SIP softswitch to RFC 3261. In mobile, GCF and PTCRB run formal conformance and interoperability programmes that vendors must pass before equipment can be deployed on operator networks.

Conformance Testing in context

The mobile core is where subscriber sessions, mobility and policy live. In 4G it is the EPC (MME, HSS, S/PGW); in 5G it is the Service-Based Architecture with AMF, SMF, UPF, AUSF, UDM and the NRF. Core exposure is the difference between a single-subscriber leak and a fleet-wide breach.

Signaling protocols carry the control-plane instructions that set up calls, register subscribers, hand over sessions and route SMS. SS7, Diameter, GTP-C and SIP are the four dominant families, and interconnect exposure of any of them is treated by GSMA FS.11 / FS.19 / FS.20 as a top-tier telecom risk.

To place Conformance Testing in the wider telecom-security picture, review NDR, NESAS, SM, ZIP, MTSI and CAMARA Project.
