Authentication vectors
Check AIR/AIA exchanges, vector contents and predictable handling of authorization failures.
4G EPC / subscriber data
HSS Testing for trusted subscriber identity.
Assure authentication vectors, subscriber-data delivery and location procedures before they interrupt attach and service flows.
Explore HSS scenarios →Assurance coverage
Qualify every exchange that identifies a subscriber.
Validate HSS signalling and subscriber data with configurable IMSIs, profiles and expected Diameter responses.
Subscriber profiles
Verify subscription data, APN configuration and serving-node information delivered to the network.
Location procedures
Test update, cancel and purge location procedures across standard and negative scenarios.
Supported 3GPP standards
HSS standards coverage.
Verify subscriber identity, data and authentication procedures against EPC standards.
EPS architecture
HSS roles in E-UTRAN access and EPS procedures.
S6a / S6d
Diameter applications and procedures between HSS and serving nodes.
EPS security
System architecture security and EPS authentication context.
Release-ready evidence
Take uncertainty out of subscriber data paths.
Get explicit assertion results for every Diameter request, answer and relevant AVP.
Diameter AVP validation
Assert mandatory and conditional AVPs, codes and values without manual trace inspection.
MME coordination
