All other product or service names are the property of their respective owners. © Motorola, Inc. 20XX IEEE Communications Quality & Reliability Starting Point Motorola is delivering seamless mobility All-IP Networks (AIPN) Control via IP Multi-media Services (IMS) Success of seamless services depends on subscribers total quality of experience Seamless services over AIPN with new control elements will have challenging new behaviors We have the responsibility of understanding the end-to- end problem and solution space so Seamless Mobility will succeed

All other product or service names are the property of their respective owners. © Motorola, Inc. 20XX IEEE Communications Quality & Reliability What is a Service? Services as perceived by the end-user Services are inherently recursive – Services embed services Services connect to services Services will change state in the middle of service delivery New features will be triggered, spawning services Services will be mobile and move between networks Services will be data-driven Machine-readable definition of a service is held in a database – Operators can create new services by adding a few data entries Service behavior will change based on subscriber data and subscriber- specific preferences, all held in databases

5 Motorola General Business Use MOTOROLA and the Stylized M Logo are registered in the US Patent & Trademark Office. All other product or service names are the property of their respective owners. © Motorola, Inc. 20XX IEEE Communications Quality & Reliability Seamless Services will have New Behaviors Operators will need to coordinate services carried across networks with different design targets, operations paradigms and user expectations. Providers will have vastly more complex design and verification issues with converged networks than with traditional cellular networks New difficulties in designing for specified availability targets, coordinating diagnostics, or verifying availability Converged services are expected to be carried across all-IP architectures, which will have significantly different behaviors that todays wireless infrastructures. All-IP networks require understanding IP best practices for system design and selection of protocols for service survivability New data-driven and policy-driven services will have new behaviors New services can be created dynamically and invoke varying sets of applications Service reliability will depend as much on the data architecture as on the physical architecture Operations systems will need new techniques to identify services and monitor successful delivery of services for accurate statistics and fault management Services will have new behaviors at both the edge and the core Intelligent end devices will make complex service-impacting decisions Service delivery will depend on residential and enterprise CPE networks not managed by the service provider Users will configure service behavior with individualized device settings and preferences
