Comprehensive Multipurpose Tool
The device under test (DUT) in the packet core network can be, for example, SGSN or SGSN combined with GGSN. EAST emulates the other network elements such as RNC, BSC, HLR, SMS-SC, and PDN nodes.
The DUT in the circuit core network can be composed of, for example, an MSC/MSC server and a media gateway (MGW). EAST emulates the other network elements surrounding the circuit core such as RNC, BSC, HLR, SMS-SC, GMSC server and MGW, GMLC, CAMEL Entity and PSTN nodes.
