1 s for Unified Communication and Collaboration of an SOA-based Converged Platform Ki-Sook Chung,, Young-Mee Shin Convergence Research team, Electronics and Telecommunications Research Institute 161 Gajeong-dong, Yuseong-gu, Daejeon, , KOREA Abstract. Since there are lots of communication means and devices such as e- mail, short messaging, messengers, wired or wireless telephone and even social network services, we need some unified communication environment for the smarter work place. We introduce a converged service platform with open service components for the unified communication and collaboration in this paper. Using the converged service platform, the third party service providers can create applications easily by composing the open service components and execute their applications since the CSP covers the entire lifecycle of services. The CSP provides UCC (Unified Communication and Collaboration) components in the form of web services. The UCC components of the CSP cover basic communication functionalities as well as social collaboration functionalities and can be mashed up into various applications for the smart collaboration in a company. Keywords: SOA,, Unified Communication 1 Introduction The SOA ( Oriented Architecture) is one of the key mechanisms which enable service developers to create new applications rapidly using existent service component with high reusability. An SOA implementation can consist of a combination of technologies, products, APIs, supporting infrastructure extensions, and various other parts [7]. We introduce an SOA-based converged service platform that specifically supports the creation, execution, and management of service components and the core UCC (Unified communication and collaboration) components which are provided by the platform. These components have been designed to provide various communication functionalities including VoIP, short messaging, , and chatting, and social functionalities such as micro-blogging, group discussion, and contents sharing among coworkers in a company.

Shin More specifically, the UCC components can be categorized into user session management, third party call control, short messaging, , directory, presence, direct messaging, bulletin board, and real-time group discussion services. These are implemented in the form of -based web services or restful web services and registered in the registry of the CSP and provide 54 operations related to UCC functionalities. As an implementation of SOA technology, these service components are opened to 3rd party service providers so that application developers can compose those components and make their applications rapidly. 2 Converged Platform The core functional parts of the CSP are shown in the figure 1 and categorized into the following 3 main functional modules. UCC service components Basics Call SMS Presence Social Network Directory Direct Msg. Discussion Group/Activity Company Board Composition Editor Semantic Annotation Semantic Discovery Composition Goal-driven Application Creation Native App Execution ID based AA 3 rd party App Runtime Execution Engines Adaptation Application Management Management Portal Application Management Management Profile Management Goal Ontology Integrated Registry / Application Repository Application/ profile User/ASP profile Fig. 1. Converged Platform Architecture Composition module This module provides semantic service creation environment to application developers. We provide a graphic service editor tool which interworks with service registry. To enable goal-driven application, this module includes semantic service annotation and discovery functions using the goal ontology and service registry. Execution module This module is responsible for running application logics and executing service components within the logic when requested. It also has identity-

This module has WAS (web application server) and ESB (enterprise service bus) as service execution facilities and interworks with other servers outside the CSP. Application management module This module provides means for managing applications, service components, and users. This module consists of data repositories for user profile, service profile, application profile, and other management facilities for the maintenance of the platform. We provide management portal site where the third party service providers and platform operators can manage their applications and related data remotely. The portal allows the access to the resources according to the user level and authorizes users who try to manipulate their resources such as their applications and relevant data.[12] 3. UCC s and Application example 3.1 UCC s The main service components of the CSP are those for unified communication and collaboration. We have targeted the convergence of IT and telecommunication services according to the recent trends of the smart work. Therefore, we implemented two categories of APIs: components for the basic communications and components for collaboration. s for the basic communication These components include , short messaging, third party call including VoIP, as well as presence service. These are implemented as -based web service similar to ParlayX web services [1]. With these APIs, application developers who have no knowledge about network protocols can make applications using network capabilities. Table 1. s for Basic Communication Communication Functionalities Type Third Party Call - make/end a Call Control - get Call Status - send Mail SMS Presence - send Short Message - send Group Short Message - get/set User Presence - get Buddy List

4 494 K.-S. Chung and Y.-M. Shin s for the collaboration With the widespread population of smartphones, lots of people use SNS (Social Network ) such as twitter [2] and facebook [3] as a means of communications. Due to these SNS, people can hear real-time news or small talks of others more rapidly and easily than before and new business models such as social commerce and social game are getting more attention. Social Directory Group Discussion Bulletin Board Table 2. s for Collaboration Functionalities - search/get a part profile - search/get a user profile - get Contact List - get/add/modify/delete Contact Information - get Group List/Group Information - get Activity List/Activity Information - get Activity Post List - add/delete/search Activity Post - get Activity Post Reply List - add/delete Activity Post Reply - get New Post Count of an Activity - get the Post Number of an Activity - get Board List - get the Count of new Post on a Board - get/add/delete One s Favorite Post List - get/search Post List of a Board - get/add/delete Post of a Board - add new Post Reply to a Board - get Reply List of a Post - get the Count of Posts of a Board - send/delete Direct Message - get DM List/DM information/new DM count Type Direct Message (DM) Using these functionalities, the company s employees can collaborate with each other and improve efficiency of their work inside and/or outside their company. The examples of the enterprise SNS are yammer [6], socialtext [5], cubetree [4] and etc. 3.2 Application example cocotime mobile app We developed several applications by composing the UCC service components. Among them, we introduce a mobile application, cocotime, which is implemented for android smart phones. The cocotime application uses lots of UCC components and it has the following functions. Group discussion: People in a group, for example, project group, can write and read one s opinions in real-time so that they can collaborate.
