Session lifecycle
Validate create, modify and delete session procedures, tunnel endpoints and response conditions.
4G EPC / serving gateway
SGW Testing for continuous subscriber sessions.
Verify the Serving Gateway’s control and user-plane behavior across session establishment, bearer handling and mobility paths.
Explore SGW scenarios →Assurance coverage
Validate user-plane continuity at every procedure.
Test SGW behaviour through the control-plane paths that determine whether subscriber traffic stays connected.
Bearer control
Exercise default and dedicated bearer handling with expected QoS and tunnel information.
Handover support
Qualify relocation and path-switch procedures that maintain sessions during LTE mobility.
Supported 3GPP standards
SGW standards coverage.
Validate serving-gateway procedures against core EPC architecture and GTP requirements.
EPS architecture
Serving gateway functions, mobility anchoring and bearer procedures.
GTPv2-C
EPS control-plane signalling for session and bearer management.
GTP-U
General Packet Radio System tunnelling protocol user plane.
Release-ready evidence
Make every handover path testable.
Capture the procedures and protocol details needed to diagnose SGW integration risks.
GTP tunnel assertions
Check TEIDs, endpoint values and sequence handling through each supported signalling path.
Interoperability workflows
Validate SGW coordination with MME, PGW and roaming partners under controlled scenarios.
SGW assurance
Keep session continuity release-ready.
Bring repeatable SGW validation to your EPC test strategy.
