4. The typical IMS architectural framework definition Here are step wise evolutions on IMS standards: 1999 - 3G.IP, the industry forum that developed the initial IMS architecture, comes into being. 2000 - Work from 3G.IP is brought to 3GPP working group as part of their standardization efforts. 2001 - 3GPP Release 4 introduces the capability of an all-IP core network as well as a bearer independent core network. 2002 - 3GPP Release 5 introduces IMS and HSDPA. 2004 - 3GPP Release 6 adds enhancements to IMS. Mid 2007 - 3GPP Release 7 will reduce the delay that affects VoIP

5. IMS as a Services Innovation track or Telco Adoption Framework The advent of IMS is seen as a more of a Services innovation model than a Telco ready adoption framework or blueprint. Some leading vendors like HP have offered models that will help Telco’s to migrate to the IMS network swiftly. There are three key steps on the HP roadmap towards IMS implementation. ■ In the short term, operators can capture CAPEX and OPEX efficiencies by focusing on network consolidation and building a foundation that will allow them to create flexible IMS infrastructure. Through consolidation , operators can gain scale and reduce the number of network elements, and ‘de-silo’ the vertical application ‘stovepipes’, making the network more IMS-ready. Examples of this approach could be consolidating Interactive Voice Response (IVR) systems, Home Location Registers (HLR), messaging platforms, and billing systems to create tight and efficient platforms that are IMS-ready. ■ In the convergence phase of the HP roadmap, operators need to put themselves into a position to address the issues of subscriber-centric, access agnostic and blended services. By enabling and upgrading the consolidated platforms created in phase one and/or injecting new IMS elements (e.g. Group List Management Server) into the network, operators can enhance their existing services and/or launch new point IMS powered applications. ■ In the third and final phase of the HP roadmap, operators move into full IMS deployment, utilizing the IMS enablers to create new multimedia services and applications not previously possible. With this final move, operators are now in a position to drive not only service innovation but significantly enhance business model flexibility and velocity.

8. Certain market driven events for operator to implement IMS The years ahead are expected to be crucial for IP Multimedia Subsystem (IMS) adoption in Asia as more service providers will look to move from trials to commercial deployment of IMS enabled networks. Asian operators and service providers are beginning to see more value in IMS and how it can help develop new market propositions with an aim to increase revenue through the provision on rich multimedia services and a new mobile experience that IMS is poised to provide. The architecture in itself, enables multiple services to be clubbed together in real time, providing subscribers with the use of voice, data, and multimedia applications in a single call or integrated session. This offering of the future promises to be a significant new source of revenue for operators, as people increasingly adopt the mobile lifestyle.
