GSMA Open Connectivity Initiative
Current paradigm of bilateral relationships will unlikely meetexpectations of 600+ operators going forward
One-to-one needs to be replaced by a many-to-many model
Global Roaming
- To ensure that an operator is able to allow its customers to roamon the network of any other GSMA member.
Global Inter-working
- To ensure that the customers of all 3GSM networks (and infuture, other technologies) can send and receive services
between themselves.Optimization of Costs
- To ensure cost-optimization for operators in establishing andmaintaining global roaming & inter-working agreements.

An EMC initiative
Supported by the GSMA Board
Started in March 2005 as part of the Roaming Refresh
Focusing on:
- Short-term: Improving efficiency of establishing andmaintaining bi-lateral inter-working and roamingagreements.
- Longer-term: Looking at new solutions, such as Hubs, toenable quick and easy establishment of new (multi-lateral)agreements.

From GRX to IPX
GRX is today ONLY a high quality Bit PipeWe need to add intelligence in the networks
- SIP Proxy
- Session Border control
- Media Gateway control (reach of fixed networks)
- Monitoring and reporting platforms
High QoS and SLAs
GRX -> IPX : GRX becomes service aware !!!
