Multimedia Messaging Service Center in a Component Based Architecture

Multimedia-sanomanvälityspalvelu (MMS) on matkapuhelinten väliseen viestintään kehitetty palvelu, joka mahdollistaa yhteyden Internet maailmaan. Multimedia-sanomanvälityspalvelua voidaan käyttää luomaan yhteys matkapuhelimen käyttäjän ja ulkoisen sovelluspalvelimen välille. MMS voidaan nähdä sovelluksena, joka yhdistää multimediaviestin luonnin, käsittelyn sekä toimituksen monelle eri sisältö tyypille. Multimedia-viestikeskus (MMSC) on uusi verkkoelementti, joka on vastuussa multimediaviestien varastoinnista ja toimituksesta. Multimedia-viestikeskuksella on kolme loogista elementtiä, jotka ovat välityspalvelin, sovellusrajapinnat ja matkapuhelinverkkorajapinta. Operaattorit sekä kolmannen osapuolen sovelluskehittäjät voivat kehittää lisäarvopalveluita multimedia-sanomanvälityspalvelulle hyödyntämällä sovellusrajapintoja. Sovellusrajapinnat perustuvat olemassa oleviin Internet protokolliin. Tämä diplomityö tutkii Multimedia-sanomanvälityspalvelun verkkoelementtien rajapintoja. Tulevaisuudessa on tarkoitus lisätä Multimedia-sanomanvälityspalvelun verkkoelementtejä sähköisen kaupankäynnin kehysarkkitehtuuriin, joka perustuu komponentteihin.

Adding Value to Message Mediation in Multioperator MMS Network Architecture

Mobiiliviestintään käytetystä lyhytsanomapalvelusta (Short Messaging Service, SMS) on tullut ilmiömäinen menestys. SMS-palvelulle on tulossa seuraaja, jota kutsutaan monimediaviestipalveluksi (Multimedia Messaging Service, MMS). MMS-viestit voivat sisältää useita erilaisia kuva-, ääni- ja videoformaatteja. Vaikka yhteensopimattomia SMS-keskuksia yhdistämään tarvitaan Intellitel Messaging Gatewayn kaltaisia sanomanvälitystuotteita, ei tällainen SMS-keskeinen lähestyminen sanomanvälitykseen ole MMS-kykyisen sanomanvälittimen kannalta järkevä ratkaisu. MMS-kykyisen sanomanvälittimen täytyy lisätä arvoa itse sanomanvälitysprosessiin, jotta tuotteesta tulisi menestyksekäs. Tässä työssä käsitellään MMS-sanomanvälityksen ongelmallisuuksia. Erityisesti painotetaan MMS-kykyisen sanomanvälittimen kehittämistä olemassaolevasta SMS-sanomanvälitintuotteesta, sekä selvitetään syitä arvonlisäyksen välttämättömyydelle. Työssä esitetään myös erilaisia arvonlisäystapoja MMS-sanomanvälitykseen. Eräitä esitetyistä arvonlisäystavoista käytetään käytännön osassa toteutetussa Nokian MMS-keskuksen MM7/VAS-rajapintaan kytkeytymään kykenevässä sanomanvälityskomponentissa.

Assessing intellectual capital in a research institute environment in steel industry

Diplomityön tavoitteena oli tutkia aineettoman pääoman hallintaa terästeollisuuden tutkimuslaitosympäristössä, sekä luoda mittaristo kuvaamaan sen tilaa ja kehitystä. Työn rajausten mukaan aineeton pääoma jaettiin Annie Brookingin jaottelun mukaan, ja tarkasteluun valittiin teollisoikeudet sekä henkilöstövoimavarat. Empiirinen osa työstä perustui pääasiassa haastatteluihin sekä Case –yrityksen sisäisiin julkaisuihin. Näitä pyrittiin tulkitsemaan kvalitatiivisten tutkimusmenetelmien oppien mukaan. Tutkimustulosten perusteella voidaan todeta teollisoikeuksien hyödyntämisen olevan suhteellisen vähäistä terästeollisuuden parissa. Syitä tähän on työssä käsitelty melko laajasti. Henkilöstön kehittäminen pitkällä tähtäimellä sekä tiedonkulun tehostaminen henkilöstön keskuudessa ovat puolestaan asioita, joihin kiinnitetään kyseisellä teollisuudenalalla kiitettävässä määrin huomiota. Työn loppupuolella esitelty aineettoman pääoman mittaristo tarjoaa yritykselle työkalun, jonka avulla voidaan monipuolisesti arvioida tätä yrityksille nykyisin elintärkeää asiaa. Lopullista ratkaisumallia se ei aineettoman pääoman mittaamiseen tarjoa, mutta luo kuitenkin tärkeän ensiaskeleen kohti tulevaisuuden yhä kehittyneempiä mittausmenetelmiä.

Architecture for a Session Initiation Protocol Based Presence Client

Mitä on läsnäolo? Tämä työ määrittelee läsnäolon tietyn henkilön, laitteen tai palvelun halukkuudeksi kommunikoida. Nykyään on olemassa lukuisia läsnäolotietoa levittäviä sovelluksia, joista jokainen käyttää erilaista protokollaa tehtävän suorittamiseen. Vasta viime aikoina sovellusten kehittäjät ovat huomanneet tarpeen yhdelle sovellukselle, joka kykenee tukemaan lukuisia läsnäoloprotokollia. Session Initiation Protocol (SIP) voi levittää läsnäolotietoa muiden ominaisuuksiensa lisäksi. Kun muita protokollia käytetään vain reaaliaikaiseen viestintään ja läsnäolotiedon lähetykseen, SIP pystyy moniin muihinkin asioihin. Se on alunperin suunniteltu aloittamaan, muuttamaan ja lopettamaan osapuolien välisiä multimediaistuntoja. Arkkitehtuurin toteutus käyttää kahta Symbian –käyttöjärjestelmän perusominaisuutta: asiakas-palvelin rakennetta ja kontaktitietokantaa. Asiakaspalvelin rakenne erottaa asiakkaan protokollasta tarjoten perustan laajennettavalle usean protokollan arkkitehtuurille ja kontaktitietokanta toimii läsnäolotietojen varastona. Työn tuloksena on Symbianin käyttöjärjestelmässä toimiva läsnäoloasiakas.

A Generic Framework Architecture for Portal Front End

A modem software development requires quick results and excellent quality, which leads to high demand for reusability in design and implementation of software components. The purpose of this thesis was to design and implement a reusable framework for portal front ends, including common portal features, such as authentication and authorization. The aim was also to evaluate frameworks as components of reuse and compare them to other reuse techniques. As the result of this thesis, a goo'd picture of framework's life cycle, problem domain and the actual implementation process of the framework, was obtained. It was also found out that frameworks fit well to solve recurrent and similar problems in a restricted problem domain. The outcome of this thesis was a prototype of a generic framework and an example application built on it. The implemented framework offered an abstract base for the portal front ends, using object-oriented methods and wellknown design patterns. The example application demonstrated the speed and ease of the application development based on the application frameworks.

Benefits and Limitations of Service Oriented Architecture

In this thesis I examine Service Oriented Architecture (SOA) considering both its positive and negative qualities for business organizations and IT. In SOA, services are loosely coupled and invoked through standard interfaces to enable business process independence from the underlying technology. As an architecture, SOA brings the key benefit of service reuse that may mean anything from simple application reuse to taking advantage of entire business processes across enterprises. SOA also promises interoperability especially by the Web services standards that enable platform independency. Cost efficiency is mainly a result of the savings in IT maintenance and reduced development costs. The most severe limitations of SOA are performance implications and security issues, but the applicability of SOA is also limited. Additional disadvantages of a service oriented approach include problems in data management and complexity questions, and the lack of agreement about SOA and its twofold nature as a business as well as technology approach leads to problematic interpretation of the available information. In this thesis I find the benefits and limitations of SOA for the purpose described above and propose that companies need to consider the decision to implement SOA carefully to determine whether the benefits will outdo the costs in the individual case.

Enterprise architecture – the foundation for a strategy

This artcle describes work done with enterprise architecture of the National Digital Library. The National Digital Library is an initiative of the Finnish Ministry of Education and Culture. Its purpose is to promote the availability of the digital information resources of archives, libraries and museums, and to develope the long-term preservation of digital cultural heritage materials. Enterprise architectures are a tool for strategic management and planning. An enterprise architecture also functions as an aid at a more practical level. It shows, for example, what kind of changes and improvements may be made in one system without overlap or conflict with other systems.

The Application of Enterprise Architecture Approach to Military Concept Development–Case Study

Abstract—Concept development and experimentation (CD&E) plays an important role in driving strategic transformation in the military community. Defence architecture frameworks, such as the NATO architecture framework, are considered excellent means to support CD&E. There is not much empirical evidence, however, to indicate how enterprise architectures (EA) are applied in the military community or particularly in military CD&E. Consequently, this paper describes and discusses empirical application of the EA approach in CD&E. The research method in the paper is a case study. Situational method engineering (SiME) is used as a framework to adapt the EA approach to the case project of the paper. The findings of the paper suggest that the EA is applicable to CD&E work, although all aspects of the original concept could not be expressed in the EA model of the case project. The results also show that the SiME method can support in applying the EA framework to the CD&E in the case project.

Transition management and the sustainable nutrients economy in the Netherlands; positioning paper

In this positioning paper transition management (TM) and the sustainable nutrient economy are addressed. We discuss TM from its scholarly origins in the 1990’s to its implementation as a comprehensive sector-wide policy program on sustainability in The Netherlands during the first decade of the 2000´s. Although the program was innovative and provoked a new approach to environmental policy and governance, the program at large failed to set the right conditions under which sustainable transition take place. Lessons from the Netherlands, both successful and less successful, are addressed in this positioning paper to inform Finnish governmental and knowledge institutes on how (not) to implement TM on environmental issues. When looking at sustainable nutrient economy the paper takes a historical view at how problems with nutrients (especially phosphates) were dealt with in the Netherlands during the post World War II era. This transition did not occur easily. In the agricultural sector environmental policies to prevent nutrient problems were not easily accepted, as large agricultural economic interests were at stake and the sector’s main actors were generally opposed to (radical) environmental transition. Currently, sustainable nutrient economy initiatives are starting to receive attention on the political agenda once again. In 2011 a sector- and chain-wide covenant was signed, showing that sustainable nutrient transition goals get commitment from stakeholders throughout the nutrient chain. We judge that TM provides useful elements that are applicable to Finnish governance modes to support sustainable nutrient economy transition. However, the Finnish government should be careful when implementing TM to prevent making the same mistakes the Dutch government made in previous years.

Ecosystem architecture design: endogenous and exogenous structural properties

The aim of this dissertation is to bridge and synthesize the different streams of literature addressing ecosystem architecture through a multiple‐lens perspective. In addition, the structural properties of and processes to design and manage the architecture will be examined. With this approach, the oft‐neglected actor‐structure duality is addressed and both the position and structure, and action and process are under scrutiny. Further, the developed framework and empirical evidence offer valuable insights on how firms collectively create value and individually appropriate value. The dissertation is divided into two parts. The first part comprises a literature review, as well as the conclusions of the whole study, and the second part includes six research publications. The dissertation is based on three different reasoning logics: abduction, induction and deduction; related qualitative and quantitative methodologies are utilized in the empirical examination of the phenomenon in the information and communication technology industry. The results suggest firstly that there are endogenous and exogenous structural properties of the ecosystem architecture. Out of these, the former ones can be more easily influenced by a particular actor whereas the latter ones are taken more or less for granted. Secondly, the exogenous ecosystem design properties influence the value creation potential of the ecosystem whereas the endogenous ecosystem design properties influence the value appropriation potential of a particular actor in the ecosystem. Thirdly, the study suggests that there is a relationship between endogenous and exogenous structural properties in that the endogenous properties can be leveraged to create and reconfigure the exogenous properties whereas the exogenous properties prose opportunities and restrictions on the use of endogenous properties. In addition, the study suggests that there are different emergent and engineered processes to design and manage ecosystem architecture and to influence both the endogenous and exogenous structural properties of ecosystem architecture. This study makes three main contributions. First, on the conceptual level, it brings coherence and direction to the fast growing body of literature on novel inter‐organizational arrangements, such as ecosystems. It does this by bridging and synthetizing three different streams of literature, namely the boundary, design and orchestration conception. Secondly, it sets out a framework that enhances our understanding of the structural properties of ecosystem architecture; of the processes to design and manage ecosystem architecture; and of their influence on the value creation potential of the ecosystem and the value capture potential of a particular firm. Thirdly, it offers empirical evidence of the structural properties and processes.

A cyber security architecture for military networks using a cognitive network approach

Cyber security is one of the main topics that are discussed around the world today. The threat is real, and it is unlikely to diminish. People, business, governments, and even armed forces are networked in a way or another. Thus, the cyber threat is also facing military networking. On the other hand, the concept of Network Centric Warfare sets high requirements for military tactical data communications and security. A challenging networking environment and cyber threats force us to consider new approaches to build security on the military communication systems. The purpose of this thesis is to develop a cyber security architecture for military networks, and to evaluate the designed architecture. The architecture is described as a technical functionality. As a new approach, the thesis introduces Cognitive Networks (CN) which are a theoretical concept to build more intelligent, dynamic and even secure communication networks. The cognitive networks are capable of observe the networking environment, make decisions for optimal performance and adapt its system parameter according to the decisions. As a result, the thesis presents a five-layer cyber security architecture that consists of security elements controlled by a cognitive process. The proposed architecture includes the infrastructure, services and application layers that are managed and controlled by the cognitive and management layers. The architecture defines the tasks of the security elements at a functional level without introducing any new protocols or algorithms. For evaluating two separated method were used. The first method is based on the SABSA framework that uses a layered approach to analyze overall security of an organization. The second method was a scenario based method in which a risk severity level is calculated. The evaluation results show that the proposed architecture fulfills the security requirements at least at a high level. However, the evaluation of the proposed architecture proved to be very challenging. Thus, the evaluation results must be considered very critically. The thesis proves the cognitive networks are a promising approach, and they provide lots of benefits when designing a cyber security architecture for the tactical military networks. However, many implementation problems exist, and several details must be considered and studied during the future work.
