IP Multimedia Subsystem (IMS)
Hosted by Tatara Systems
May 17, 2006
Chair: Peter Rysavy, Rysavy Research
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.

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.
