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

IMS in the Market
Leading operators committing big $ to IMS networks
– BT– Sprint
80+ IMS trials (mostly core IP networks now)WiFi Cellular Convergence
– Deutsche Telecom– France Telecom– Sprint– SBC– Telecom Italia– Many more Huge hype
Many trials – basic servicesEarly for rich or converged services
Operators are thinking through their options

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 experienceconsistent 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)

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 networksNot a full “one service” experience yet!!
Different device types, different device capabilities, different OSs makes this difficult
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 developersIn the same way that IMS enables third-party development of network-based services, OSGitechnology promotes third-party development of end-device based services
12
What Should the OSGi Alliance Do?
Mobile network operators are just beginning to really look at the deployment of “rich” converged servicesNow is the time to address the issuesThe OSGi Alliance needs to work with 3GPP (via OMA?) to ensure that IMS can support OSGiservice platform capabilities such as:
– Remote management– Service lifecycle management– Service portability
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” devicesThe 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
