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 !!!
