IMS is a service platform for IP multimedia applications. Potential applications include VoIP, PoC (push-to-talk over cellular), streaming video, and video conferencing. For example, a user on a voice call can enable a simultaneous video connection or file transfer. Or during an interactive chat session a user can can launch a voice call. Or during a Web session, a user could decide to speak to a customer-service representative with a VoIP connection. IMS by itself does not provide all these applications. Rather it provides a framework of application servers, subscriber databases and gateways to make them possible. The exact services will depend on operators and application developers who make these applications available to operators. For the most part, these won't be applications that are enterprise-hosted. However, the operator services will be able to intelligently interact with Internet-based and enterprise-hosted services because IMS is based on standardized networking protocols.

The core networking protocol used within IMS is SIP (Session Initiation Protocol), which uses its companion protocol SDP (Session Description Protocol) to convey configuration information such as supported voice codecs. Other protocols include RTP (Real Time Protocol) and RTSP (Real Time Streaming Protocol) for transporting actual sessions. Though specified by 3GPP, IMS is relatively independent of the radio access network and can and likely will be used by other radio access networks. It can even be used with wireline networks such as DSL and cable. Operators are already trialing IMS. Video sharing while on a voice call is likely to be an early IMS-based applications. Operators looking to roll out VoIP over networks such as CDMA2000, HSDPA and WiMAX will also likely use IMS.

The meeting will address questions such as:

  • What is the status and reality of VoIP over 3G?
  • What is the IMS architecture and what are the key protocols?
  • What is the status of operator deployment of IMS?
  • What are key applications under consideration for IMS?
  • Will VoIP be an important IMS driver?
  • Who are the key players in making IMS a reality?
  • To what extent will IMS enable convergence between fixed and mobile systems?
  • What is the relationship of Unlicensed Mobile Access (UMA) with IMS?
  • What is the role of QoS for IMS applications?
  • What are the opportunities for the mobile computing industry with IMS?

Abstracts for the presentations will be added as they become available.  

Joel Hughes, VP Business Development, NMS Communications. IMS Applications
The promise of IMS is built around the delivery of a host of new multi-media applications which will drive operator data revenues. This session will review the current IMS applications of interest including Video Sharing, Content Sharing, Active Phone Book, Push-to-talk, Instant Messaging and the status of their commercial readiness, trial activities and deployments worldwide. In particular, we will explore the role of the mobile handset client in delivering these IMS Applications and the interoperability requirements of IMS elements as well as cross-operator interoperability.

Ron Nevo, Intel. IMS on PCs

As service-providers adopt fixed-mobile convergence strategy and IMS as the technology to realize this strategy the PC becomes a viable client device which they need to address. The PC as IMS is important for a number of reasons. First, in order to maintain customer loyalty service-providers should have their presence on all of users’ devices. Second, PC platforms are best positioned to accelerate the TTM of new IP services; traditionally phones were the bottle neck of any new service roll out. The PC enjoys development ecosystem and flexibility that can dramatically change the rate of innovation for new IMS services. What are the required actions to guarantee a win-win cooperation between the PC industry and the service provider industry for the long run.

Leigh Chinitz, Director of Marketing & Business Development, Airvana. 3GPP2 and IMS

Network operators are enhancing their core networks to support the creation of, and the ability to provide, a large number of new services. The deployment of an IMS infrastructure is intended to create the kind of service creation environment that will allow telecom service providers to be as nimble at creating and deploying new services as are service providers using IP-based networks such as the global Internet. One of the results of this IMS build-out is a desire by service providers to extend the reach of these new services to new customers, and to existing customers in new locations. They will do this by taking advantage of alternative access networks, meaning that wireless networks of the future will be a combination of traditional technologies such as CDMA and UMTS with IP-based access technologies like Wi-Fi, Bluetooth and WiMAX, coupled with IP-based backhaul infrastructure, including ISP networks and the global Internet. While much of the focus on IMS has been on the signaling elements and application services, service providers will also be required to adapt their network architectures to support user requirements for security, mobility and quality of service (QoS). The standards bodies have defined specific sets of functionality (the PDG in 3GPP and the PDIF in 3GPP2) which are enablers of FMC, and these will be important elements in enabling service providers to expand the reach of their IMS-based applications.

Dr. Asa Kalavade, Founder and CTO, Tatara Systems. Convergence Solutions
Service and content providers are increasingly interested in deploying converged communication and content services as users continue to become more mobile, devices become more powerful, and broadband networks become more ubiquitous. Examples of such services include converged voice and messaging services and adaptive content and multimedia services. Service providers are starting to deploy IMS infrastructure to deploy such applications. However service providers cannot afford to wait for full IMS implementations in today’s highly competitive environment; they must deliver revenue generating converged services today, while ensuring that the equipment they invest in will gracefully migrate to IMS over time. In this session we will discuss how these converged applications can be deployed in pre-IMS networks, while evolving to a full IMS implementation.
