Improving Enterprise Service Solutions with IMS Architectures Session IMS-03: IMS in the EnterpriseJanuary 24th, 2007 Ray Adensamer Senior Manager, Product Marketing RadiSys
Topics • Traditional Approaches to Enterprise Service Solutions • The Carriers Approach • Adoption of Decomposed Services Architecture • The IMS Architecture • Extending service decomposition to any access or device • ATCA platform reuse in IMS • Benefits for Enterprise Customers • Example IMS Services in the Enterprise • Conclusions and Trends
Enterprise Voice Services Traditional Challenges • Services delivered as stand-alone “Service Nodes” • Each Service Nodes often has their own: • Proprietary architecture • Management systems and service databases • Often tied to a access network subset • Resulting characteristics and operational limitations • Multiple systems and databases to manage • Voice only -> complex interworking with IP-based data services • New service introduction – complex and slow IVR PBX ACD Voicemail SpeechServices Audio Conferencing Server CallRecording Legacy TDM Network
What are Carrier’s Doing? Service Decomposition Class 5Softswitch Messaging Software MobilitySoftware Speech PortalSoftware PrepaidSoftware Conferencing Software • “Service Nodes” decomposed into • Application logic and • Media processing. • Application logic executes on off-the-shelf servers. • Media processing is shared across many services. • Interconnection through open standards-based interfaces.

IMS Benefits for Enterprise Customers (…and their suppliers) • One Architecture for Any Service • Supports Multimedia and Multimodal services • One Architecture for Any Access Technology • Abstraction of access technologies allows a single service architecture to support any device. • Rapid Service Introduction • Reuse of common infrastructure accelerates adding new service capabilities and features • Maximize Flexibility • Mix and match best-of-breed equipment and applications using open standards-based interfaces
Real-World ExampleEnterprise with Decomposed Services • Fortune 500 Company • 160+ countries, • 1500 locations, • 900+ PBX’s in • 700+ facilities, • 400,000 phones, • 450 voicemail systems, • 160 IVR systems, • 156 call centers • IP network implemented to consolidate, improve management and resiliency, and enable “voice as an on demand application” • Infrastructure delivering over 1 Billion conferencing minutes per year (50% savings) and leveraging same infrastructure for IVR and Voicemail applications as well as fixed/mobile convergence.

Conclusions and Trends • VoIP in Enterprise is growing • However, “Service Node” architectures are still common • The design driver is reuse: • Service decomposition allows many applications to share multimedia processing and control infrastructure • IMS extends service decomposition to any access network • ATCA delivers similar reuse qualities in hardware platforms • Benefits include rapid service innovation with lower costs. • Carriers are leading the way towards IMS architectures • Expect IMS adoption in Enterprise to accelerate quickly.
