A new communications architecture that will enable true peer-to-peer wireless communication and client/server operation is being developed jointly by leaders in the mobile communications and Internet networking industries. The resulting new architecture will deliver a world-class, IP–based networking solution to wireless network operators worldwide. The architecture supports current wireless standards and assists operators in their migration efforts to the emerging 3G wireless systems.

Figure 9. Wireless IP Vision and Value Proposition for Global Operators

Four primary attributes of the architecture and the value propositions they represent for network operators are as follows:

1. superior end-user experience—The architecture specifically targets the open philosophy and application-enabling capacity of IP for creating an RAN and core network infrastructure designed with the subscriber in mind and tuned for supporting the many new feature characteristics delivered by innovations in mobile station technology. The mobile subscriber will enjoy a freedom unequaled by other network access and service-delivery systems.

2. orderly operator network migration—The architecture provides operators with an orderly migration path to IP–based networking for achieving peer-to-peer, nonhierarchical communication and a client-server operation while maintaining interoperability with the existing RAN infrastructure. An operator can introduce new, IP–based services while maintaining support for existing services and capabilities. Furthermore, each operator can choose how and at what speed it should deploy 3G wireless systems. A distributed network model will demonstrate significant gains in system performance, quality of service (QoS) capacity, and scalability. Operations costs will be reduced, and more intelligent operations, maintenance, and provisioning will be enabled across the network.

3. reduced cycle time to commercialize applications—The architecture permits the separation of subscriber services and the wireless network, thereby enabling network operators flexibility in deploying end-user services and applications independent of wireless switch manufacturers. Through open, external application programming interfaces (APIs), operators and third-party developers are able to deliver new features and applications in a rapid fashion. The end result is an expanded solution set, with faster and more economical deployment for generating new revenue streams for the operator.

4. reduced cost of ownership—The architecture will provide the framework for innovative technology enhancements. The wireless network will include features such as an interworking function to optimize the bearer path and processing resources to ensure that the right resources are being assigned for optimal service delivery. Network operators can reduce operating costs through the higher efficiencies and scaling of IP packet transport. The distributed client/server operation of the network allows network functions to be co-located or spread out to allow for greater operational efficiency and reduced costs.
