SS. 3.2 WIMS 2.0 Initiative 3.2.1 What Is WIMS 2.0? WIMS 2.0 (Web 2.0 and IMS) {WIMS 2.0} is an open initiative founded by Luis Angel Galindo and David Moro. WIMS 2.0 seeks convergence between the Web 2.0 and the telecom new-generation services based on IMS (IP Multimedia Subsystem), to create innovative, appealing, and user-centric services and applica- tions. These services will combine features from both Web and telecom worlds. On the one hand, relevant features such as interactivity, ubiquity, social-orientation, user participation, and content generation will be adopted from Web 2.0 Services; on the other, IMS will enhance WIMS 2.0 services features with a collection of capabilities such as multimedia telephony, media sharing, push-to-talk, presence and context, online address book, and SO on, all of them being applicable to mobile, fixed, or convergent telecom networks. In addition, in order to provide more versa- tile and enriched services and a short-term implementation, WIMS 2.0 also consid- ers the utilization of pre-IMS Telco capabilities such as SMS/MMS messaging, circuit-switched video and voice calls, networked address books, and SO on. WIMS 2.0 comprises the strategies, technologies, and service platforms that will allow telecom operators to achieve this convergence with innovative Web 2.0 services in All-IP networks. Following the Web 2.0 revolution and the Telco 2.0 initiative {Telco 2.0}, a change in Telco traditional business model is recommended following the adoption of a user-centric and open-garden philosophy consisting in the enhancement of the openness, flexibility, and freedom in the fashion services are provided. IMS, along with its associated set of service enablers, has been identi- fied as the base platform to support this convergence and business model change. Service Delivery Platforms The two main goals of the WIMS 2.0 initiative {WIMS 2.0} are to create inno- vative services mixing the Web 2.0 and Telco World, and to create a new fair eco- system: the WIMS 2.0 ecosystem {WIMS 2.0
