Option 1: End-to-End EPC Testing
•Single vendor offering all EPC
nodes for testing
•Focus on testing of all external
interfaces from EPC
• Integration with external simulators
and applications
Executed end-to-end EPC testing for a Tier-1 OEM using in-house simulators for optimized test
coverage

Option 2: Combinational Testing
•Vendors may offer various
combinations of LTE-EPC
nodes for testing
•Focus on testing features
relevant for the combinational
nodes
• Integration of combination
nodes with simulated/emulated
peer nodes
Successfully tested an SGW+PGW combination for a datacom vendor using in-house simulators

•Vendor offers testing for an
individual node
•Multiple inter-dependent
node(s) may be offered for
testing
•Testing of individual nodes for
all their external interfaces
Signaling vendor’s MME was successfully tested for LTE and interworking with 3G networks
