MME Test Features
MME is connected to a series of nodes in LTE network as shown in Figure 1, and the protocol stacks for each interface is shown in Figure 2. When MME is under test, the configuration would be as in Figure 3.



S-GW Test Features
S-GW is connected to a series of nodes in LTE network as shown in Figure 4, and the protocol stacks for each interface is shown in Figure 5. When S-GW is under test, the configuration would be as in Figure 6.



P-GW Test Features
P-GW is connected to a series of nodes in LTE network as shown in Figure 7, and the protocol stacks for each interface is shown in Figure 8. When P-GW is under test, the configuration would be as in Figure 6.




S-GW/P-GW Test Features
S-GW and P-GW is connected to series of nodes in LTE network as shown in Figure 11. Test configuration is shown in Figure 12.
