7. Global Network architecture

8. IMS Architecture

9. 4. Live Testing 2. Conformance Test 3. Load & Capacity testing 1. Functional Testing check the correct handling of the system’s functionalities in a real context check the functional blocks compatibility • check the performances declared by supplier • check the correct working in limit load conditions • check the correct handling of the system end-to-end functionalities verifing protocols and procedures • tipically carry out in test plant Testing Typologies

10. Scope of Testing Verify the IMS core-network through the usage of a set of reference end-to-end scenarios (including roaming users) and the analysis of signalling on the network interfaces that are involved: Gm, Cx, Mw, Mi, Mj, Mk, Mg, Mn, Rf, Go. • Verify the procedures conformity to the standard • Reduce the time to market of new network solutions
