Hutchison Whampoa is the most important greenfield 3G operators group
The project was fully focalized in UMTS: the 2G roaming agreement were not adressing an initial commercial offer in 2G band

Handset Interoperability TestFuntionality performed by UE in 3G network are much more complex than in 2G network both on network and on application level.
The correct behaviour of UEs may impact performances of the network and it is essential that UEs are extensively tested with all network vendors.
There is a growing importance of IoT departments in charge of Managing UE vendorsDefining UE application requirementsExecuting all application and network interoperability testingFinally accept any UE model

Optimization (1/2)Optimization activity on UMTS network must be carried with a particular attention because modifications on radio parameters may outcome with unexpected increase of RNC processor load or resources consumption.
Examples:
An increase of the timer supervising channel switching (DCH to FACH timer) will increase Iub usage and Node B usage (Base Band capacity occupation and Carrier Power usage).
Modification on accessibility parameters (e.g. Ec/I0) may trigger registration or location-update procedure increasing RNC processor load.

Optimization (2/2)After commercial service concept definition and go live in production environment, a fine tuning of network layer & service platform parameters has to be carried out
The tuning of procedures and parameters involved through each layer of delivery chain is essential for an optimized service delivery
• Network resource saving• Better user experience
Example: Streaming service delivery• MPEG coding scheme has been modified• IP packet size and TCP parameters have been optimized• Radio channel switching parameters have been optimized

Conclusions
Mobile Triple PlayMobile Telecommunication, Mobile
Internet&Data and Mobile Media converge in a single personal device
Focus on :
TechnologyBuilt around UMTS
UMTS – considering foreseeable evolution - offers best combination of performances, quality, security, inter-operability, industry-support
alternative wireless terchnologies can be integrated with a selective approach
