Objectives
The objectives of this activity are threefold:
- To design, develop, and validate a modular and efficient radio access network simulator for third generation mobile satellite systems;
- To carry out simulation runs with a view to optimise the simulated system; and
- Based on a thorough analysis of the simulation results, to contribute to the standardisation of the higher layer protocols involved.
Challenges
The 3G satellite network simulator covers in particular these two core capabilities:
- The capability to perform a thorough analysis of satellite UMTS radio access networks; and
- The capability to study the interworking of the satellite UMTS radio access networks with the terrestrial UMTS IP core networks.
Plan
| The study was initiated in early 2003 with the final delivery scheduled for October/November 2004. The activities are organised into several steps as sketched in the following diagram: |  click for larger image |
Current Status
The simulation and optimisation runs were completed and the draft final delivery package was submitted in October 2004. The Final Presentation is foreseen for 28 January 2005.
