White Paper

  • As the industry moves more towards full-scale IP networks, the issue of interconnecting diverse networks and different service providers - each with its own IP network(s) - becomes more important to resolve in order to support the seamless delivery of next generation services. There will be concerns for security and end-to-end quality of service (QoS) to be addressed to make sure the different “moving parts” that make up these services are delivered to the customer in the expected manner.  It will be important to set up the mechanism by which all the participants in the service delivery supply chain are compensated for the value they provide to the overall end-to-end service.

    The GSMA IP eXchange (IPX) provides a visionary approach to the challenges fixed and mobile service providers have with interworking IP-based services and networks. It provides multiple, service-aware connectivity models that provide QoS as well as cost efficient, optimal routing of IP traffic. The same platform can be extended to bridge the gap between IP and legacy TDM networks.
