SMS Load Generation

SMS Load Generation
SMS over Gb / IuCS / IuPS SMS over S1

The NG40 Core Network Emulator provides the functionality of a Short-Message-Service Center. Aim of this emulation is SMS injection into the RAN (GERAN/UTRAN/eUTRAN) subsystem. For conveniance and test bed simplification, all generated short messages will be delivered directly to the borders of the Radio Access Network (see SMS Injection Points above).

NG40 generates up to 15.000 SMS/sec for up to 2 million mobile subscribers.

The supported protocol stacks for SMS generation are depicted at the diagram below:
