SEPs allow CSPs to expose their networks to the Web developer community via simple Web services. By taking this approach, CSPs are able to tap the innovation of the Web community while remaining focused on their strengths – like messaging, presence, conferencing, subscriber profile data, and the ability to charge through their networks.
To succeed with a SEP approach, CSPs have to reach out to Web developers and offer them inexpensive and easy access to the telecom capabilities in their networks. They need to provide a secure, easy-to-use application platform that supports both IT and telecom industry standards. Further, in order to effectively compete with Internet providers, CSPs need to deploy services quickly. Some service providers that have migrated from proprietary systems to platforms based on industry standards, such as Java EE or Session Initiation Protocol (SIP), have reduced application development timeframes by more than 30%.

a great deal of revenue from them, in part, because they are offering only telecom services, not converged services or blended applications. Most IMS services revolve around call control and video, such as VoIP over IMS, or video telephony over IMS, or in some cases IPTV over IMS. But CSPs with IMS networks have not yet fully grasped the vast opportunities available in the Web domain to leverage IMS/NGN capabilities. The challenge then is to increase the development of converged Web-IMS applications, where the real-time communication and collaboration capabilities native to IMS networks and NGNs can deliver uniquely differentiating capabilities to Internet and Web 2.0 applications and services. CSPs can encourage adoption of their IMS/NGN capabilities by regional and global Web 2.0-enabled social networks, or Internet portal and commerce companies, by allowing the Internet/Web 2.0 companies to

Several CSPs have successfully deployed blended applications commercially with the SEP approach including Telefónica O2 UK Limited, a leading communications company for consumers and businesses in the United Kingdom. The company launched its O2 Litmus project to work with developers to create a wide range of wireless and Internet-enabled applications and services and then allow O2 customers to test and rate them. Other service providers taking this approach include Telecom Italia, 3 and SingTel.
Next-Generation Network Approach
Another approach service providers can take is pursuing blended applications through NGNs, such as IP Multimedia Subsystem (IMS) or Multimedia Domain (MMD). CSPs are investing hundreds of millions of dollars into NGNs based on IP technology, with IMS being the most popular. However, many CSPs have deployed IMS services but are not generating

easily access and create blended applications on top of their NGNs. While this approach may involve a significant investment on the part of the Internet and Web 2.0 companies, as well as the CSPs, it allows everyone to benefit from the richness and innovation of blending the Web domain with the telecom domain. With the NGN approach, CSPs also have increased control over which Internet or Web 2.0 capabilities they would like to blend with their IMS/NGN networks, as well as the roadmap for new converged services based on blended applications.
Several service providers have launched NGN services, including SK Telecom and KTF , the two largest mobile operators in South Korea; Softbank Mobile Corp in Japan, one of the first providers to deploy an IMS network over 3G; and mobilkom austria group, a leading mobile service provider in Central and Eastern Europe. These CSPs, as well as many others
