| C.Code |
R03 |
| Objectif |
This training addresses the planning and design principles of the UMTS network systems, core and related transmission networks. The core network architecture concerned is based on the split architecture mainly, taking into account dimensioning criteria for control layer and connectivity layer systems. Both core network domains (i.e. Circuit and Packet Services domains) are addressed in this course.. |
