Ericssons Business Communication Suite (BCS) är en Unified Communication-lösning, och är avsedd för större företag och teleoperatörer. BCS erbjuder tjänster som snabbmeddelanden, videosamtal, lägga till kontakter i grupper samt grupphantering mm. Syftet med detta projekt var tvåfaldigt; att utveckla och integrera ett program som kan kommunicera med Ericssons BCS, samt att dokumentera denna integration genom de erhållna kunskaperna från utvecklingen. Applikationen utvecklades för Windows Sidebar widget miljön och BCS miljön simulerades med hjälp av flera program och applikationer som tillhandahölls av Ericsson. Det första resultatet är en steg-för-steg integrationsguide, som innehåller installationsintruktioner för BCS-miljön samt riktlinjer för denna integration. Det andra resultatet är en widget som kan söka efter personer på sökmotorn www.eniro.se och utnyttja tjänster som tillhandahålls från BCS, som kontakt-och grupphantering samt videosamtal. Detta projekt visar att en tredjepartsutvecklad applikation kan integreras med BCS, och att tredjepartsutvecklare samt anställda på Ericsson kan använda steg-för-steg integrationsguiden för att sätta upp test- och utvecklingsmiljö för BCS. / Ericsson Business Communication Suite (BCS) is a Unified Communication solution destined for larger companies and telecommunication operators. BCS offers services such as instant messaging, video calls, contact group management and much more. The purpose of this project was twofold; developing and integrating an application that could communicate with Ericsson's Business Communication Suite, but also to document this integration through the knowledge acquired from the development. The application was developed for the Windows Sidebar widget engine and a BCS environment was simulated with the help of several programs and applications provided by Ericsson. The results of the project are a step-by-step integration guide, which contains environment setup as well as integration guidelines, and also a widget application that can search for people on the search engine www.eniro.se and utilize services provided by BCS such as contact and group management and video calls. This project demonstrates that a third party developed application can be integrated with Ericsson BCS, and that third party developers and people at Ericsson can use the step-by-step integration guide to easily setup the necessary BCS test environments.

Speech as a medium for communication has always been important in its ability to convey our ideas, personality and emotions. It is therefore not strange that Quality of Experience (QoE) becomes central to any business relying on voice communication. Using Unified Communication (UC) systems, users can communicate with each other in several ways using many different devices, making QoE an important aspect for such systems. For this thesis, automatic methods for assessing speech quality of the voice calls in Briteback’s UC application is studied, including a comparison of the researched methods. Three methods all using a Gaussian Mixture Model (GMM) as a regressor, paired with extraction of Human Factor Cepstral Coefficients (HFCC), Gammatone Frequency Cepstral Coefficients (GFCC) and Modified Mel Frequency Cepstrum Coefficients (MMFCC) features respectively is studied. The method based on HFCC feature extraction shows better performance in general compared to the two other methods, but all methods show comparatively low performance compared to literature. This most likely stems from implementation errors, showing the difference between theory and practice in the literature, together with the lack of reference implementations. Further work with practical aspects in mind, such as reference implementations or verification tools can make the field more popular and increase its use in the real world.
