Evaluation of OSA API's for 3rd party developers of Telco-services

Abstract

Changes in business models introduce new actors to the telecom business. A set of new demands occurs and to handle this, a technical enabler like OSA is needed. Telenor R&D, which often provides Telco services in research projects, must form an opinion concerning this framework. Thus an evaluation of OSA is inquired. This thesis presents an introduction and evaluations of the OSA framework, further, a closer look at two of the OSA API’s (User Status and Terminal Capabilities) are made. To enhance the evaluation, Youngster has been utilized as an example of where the OSA framework can be used. An implementation of one of the API’s has also been done with the use of Web Services and CORBA. Our main conclusion is that OSA has not managed to make the framework userfriendly. Too many details must be implemented to get access to Telco services, and 3rd party developers need to know unnecessary much about telecommunication.
