Abstract |
|
|
| In order to improve the efficiency of maintaining packet core network and test the network elements, a simulation testing
system for GPRS and UMTS 3G packet core network is proposed. The system can simultaneously simulate several network elements
to connect with SGSN, GGSN, WAP gateway respectively for testing. In the system, multiple UEs can be simulated, and multiple
applications can run on each UE. Protocol Stack Pool is developed to accommodate several protocol stacks at Gb, Iu-PS, Gn, Gi
interfaces. Simulated UEs can communicate with the network side equipments through the Protocol Stack Pool. The system was
implemented in Linux operating system and a web-based management subsystem was provided. The system was tested by Tektronix
K1297 testing equipment and by accessing the current cellular mobile communications network. We also emulate the main network
elements and set up an emulated core network to test in laboratory. The testing results show that applications can run on the system to
test the network elements. |
