  5. 5. 5 Network and Service Convergence The goal of convergence is to deliver a seamless end user experience across multiple locations, multiple devices and multiple types of use. With convergence between the mobile and fixed line networks, telecommunications operators can provide services to users irrespective of their: – location – access technology – terminal

  8. 8. 8 User Needs and Expectations AVAILABILITY In building On the road … of services AFFORDABILITY Best Value Take advantage of embedded home/enterprise networks EASE-OF-USE Transparent to users Same services/same user experience Common user profile USER EXPERIENCE Quality Consistency The game has changed… it’s about the customer experience
  9. 9. 9 Dimensions of Convergence One CoreOne Service One Device IMS-based ConvergenceIMS-based Convergence Support One Service Experience: • Single sign-on • Single profile • Service portability seamless user experience consistent service across wireline and wireless access networks Provide One Device Access: Equipped with multiple interfaces for: • various wireline and wireless access networks • varying connectivity and QoS Utilize One Core Architecture: Access-Independent IMS as the core for various wireline and wireless access networks (sharing of common resources)
  10. 10. 10 What’s Not Being Addressed? IMS does not fully support one service to many devices yet – Can do one service to some devices – Doing better at one device for services across many access networks Not a full “one service” experience yet!! Different device types, different device capabilities, different OSs makes this difficult
  11. 11. 11 How Can OSGi Technology Help? The OSGi service platform enables application developers to “write once, deploy on many” end devices – Service providers can be sure that their services will work on a variety of end devices – Attracts third-party application developers In the same way that IMS enables third-party development of network-based services, OSGi technology promotes third-party development of end-device based services
  12. 12. 12 What Should the OSGi Alliance Do? Mobile network operators are just beginning to really look at the deployment of “rich” converged services Now is the time to address the issues The OSGi Alliance needs to work with 3GPP (via OMA?) to ensure that IMS can support OSGi service platform capabilities such as: – Remote management – Service lifecycle management – Service portability
  13. 13. 13 Summary Service providers are moving to converged networks and are promoting IMS – Can (more) rapidly deploy new services – Reduce costs via a common infrastructure – Creates incentives for third-party developers The OSGi service platform supports deployment of services on “converged” devices The OSGi Alliance should work with the organizations that are defining the IMS architecture, protocols, and services to ensure that the benefits of the OSGi service platform can be realized by IMS operators
