TV taskussa - tänään ja tulevaisuudessa

The objective of my thesis was to find out how mobile TV service will influence TV consumption behaviour of the Finns. In particular the study focuses on the consumption behaviour of a well educated urban people. For my thesis, I provided a detailed analysis of the study results of a large scale questionnaire research FinPilot from the year 2005 based on an assignment of Nokia Ltd. In order to deepen the study results, I focused on the above mentioned group of young people with good education. The goal of the FinPilot research was to give answers to the following questions: what kind of programs, in what kind of circumstances, and for which reasons are they watched when using the mobile television service. The results of the research consisted mainly of data like figures, graphics etc. The data was explaned from the helicopter perspective, for it gave additional value to the research and consequently to my own thesis. My study offered complementary, unique information about their needs as it was based on questionnaires supplemented by individual interviews of the group members, their free comments as well as group discussions. The study results proved that mobile TV service did not increase the total TV consumption time. The time used for watching the mobile TV was significantly shorter than the time for watching the traditional TV. According to my study, the young urban people with good education are more interested to adapt the mobile TV service than the average Finns. Being eager to utilize the added value offered by the mobile TVs they are a potential target group in launching and marketing processes. On the basis of the outcome of the thesis, the future of mobile TV service seems very promising. The content and the pricing, however, have to match the user's needs and expectations. All the study results prove that there exists a social order for mobile TV service.

A design and a prototype for a mobile information service for tourists

Tourism is one of the biggest industry branches with billions of tourists traveling every year around the world. Therefore, solutions providing tourist information have to be up to date with both changes in the industry and the world’s technological progress. The aim of this thesis is to present a design and a prototype of a tourist mobile service which is individual-oriented, cost-free for the end user, and secure. On the information providers’ side, the solution is implemented as a Webbased database. The end users access the information through a Bluetooth application on their mobile devices. The Bluetooth-based solution allows to avoid any costs for the end users, that is tourists. The study shows that, even with small data transfers, the tourists could save significantly when compared to possible roaming charges for data transfer. Also, the proposed mobile service is not intrusive, as it is provided through an application installed by tourists voluntarily on their mobile devices. Through design and implementation this work shows that it is possible to build a system which can be used to provide information services to tourists through mobile phones. The work achieved a successful ongoing synchronization between the client and the server databases. Implementation and usage were limited to smart phones only, as they provide better technological support for the solution having features like maps, GPS, Wi-Fi, Bluetooth and Databases. Moreover, the design of this system shows how Bluetooth technology can be used effectively as a means of communication while minimizing its shortcomings and risks, such as security, by bypassing Bluetooth server service discovery protocol (SDP) and connecting directly to the device. Apart from showing the design and implementation of the end-user costfree mobile information service, the results of this work also highlight the possible business opportunities to the provider of the service.

Towards combining interactive mobile TV and smart spaces : architectures, tools and application development

Technological developments in microprocessors and ICT landscape have made a shift to a new era where computing power is embedded in numerous small distributed objects and devices in our everyday lives. These small computing devices are ne-tuned to perform a particular task and are increasingly reaching our society at every level. For example, home appliances such as programmable washing machines, microwave ovens etc., employ several sensors to improve performance and convenience. Similarly, cars have on-board computers that use information from many di erent sensors to control things such as fuel injectors, spark plug etc., to perform their tasks e ciently. These individual devices make life easy by helping in taking decisions and removing the burden from their users. All these objects and devices obtain some piece of information about the physical environment. Each of these devices is an island with no proper connectivity and information sharing between each other. Sharing of information between these heterogeneous devices could enable a whole new universe of innovative and intelligent applications. The information sharing between the devices is a diffcult task due to the heterogeneity and interoperability of devices. Smart Space vision is to overcome these issues of heterogeneity and interoperability so that the devices can understand each other and utilize services of each other by information sharing. This enables innovative local mashup applications based on shared data between heterogeneous devices. Smart homes are one such example of Smart Spaces which facilitate to bring the health care system to the patient, by intelligent interconnection of resources and their collective behavior, as opposed to bringing the patient into the health system. In addition, the use of mobile handheld devices has risen at a tremendous rate during the last few years and they have become an essential part of everyday life. Mobile phones o er a wide range of different services to their users including text and multimedia messages, Internet, audio, video, email applications and most recently TV services. The interactive TV provides a variety of applications for the viewers. The combination of interactive TV and the Smart Spaces could give innovative applications that are personalized, context-aware, ubiquitous and intelligent by enabling heterogeneous systems to collaborate each other by sharing information between them. There are many challenges in designing the frameworks and application development tools for rapid and easy development of these applications. The research work presented in this thesis addresses these issues. The original publications presented in the second part of this thesis propose architectures and methodologies for interactive and context-aware applications, and tools for the development of these applications. We demonstrated the suitability of our ontology-driven application development tools and rule basedapproach for the development of dynamic, context-aware ubiquitous iTV applications.

Drivers and barriers of mobile travel and tourism service adoption : a study of individual perceptions and business model development in a travel and tourism context

The Travel and Tourism field is undergoing changes due to the rapid development of information technology and digital services. Online travel has profoundly changed the way travel and tourism organizations interact with their customers. Mobile technology such as mobile services for pocket devices (e.g. mobile phones) has the potential to take this development even further. Nevertheless, many issues have been highlighted since the early days of mobile services development (e.g. the lack of relevance, ease of use of many services). However, the wide adoption of smartphones and the mobile Internet in many countries as well as the formation of so-called ecosystems between vendors of mobile technology indicate that many of these issues have been overcome. Also when looking at the numbers of downloaded applications related to travel in application stores like Google Play, it seems obvious that mobile travel and tourism services are adopted and used by many individuals. However, as business is expected to start booming in the mobile era, many issues have a tendency to be overlooked. Travelers are generally on the go and thus services that work effectively in mobile settings (e.g. during a trip) are essential. Hence, the individuals’ perceived drivers and barriers to use mobile travel and tourism services in on-site or during trip settings seem particularly valuable to understand; thus this is one primary aim of the thesis. We are, however, also interested in understanding different types of mobile travel service users. Individuals may indeed be very different in their propensity to adopt and use technology based innovations (services). Research is also switching more from investigating issues of mobile service development to understanding individuals’ usage patterns of mobile services. But designing new mobile services may be a complex matter from a service provider perspective. Hence, our secondary aim is to provide insights into drivers and barriers of mobile travel and tourism service development from a holistic business model perspective. To accomplish the research objectives seven different studies have been conducted over a time period from 2002 – 2013. The studies are founded on and contribute to theories within diffusion of innovations, technology acceptance, value creation, user experience and business model development. Several different research methods are utilized: surveys, field and laboratory experiments and action research. The findings suggest that a successful mobile travel and tourism service is a service which supports one or several mobile motives (needs) of individuals such as spontaneous needs, time-critical arrangements, efficiency ambitions, mobility related needs (location features) and entertainment needs. The service could be customized to support travelers’ style of traveling (e.g. organized travel or independent travel) and should be easy to use, especially easy to take into use (access, install and learn) during a trip, without causing security concerns and/or financial risks for the user. In fact, the findings suggest that the most prominent barrier to the use of mobile travel and tourism services during a trip is an individual’s perceived financial cost (entry costs and usage costs). It should, however, be noted that regulations are put in place in the EU regarding data roaming prices between European countries and national telecom operators are starting to see ‘international data subscriptions’ as a sales advantage (e.g. Finnish Sonera provides a data subscription in the Baltic and Nordic region at the same price as in Finland), which will enhance the adoption of mobile travel and tourism services also in international contexts. In order to speed up the adoption rate travel service providers could consider e.g. more local initiatives of free Wi-Fi networks, development of services that can be used, at least to some extent, in an offline mode (do not require costly network access during a trip) and cooperation with telecom operators (e.g. lower usage costs for travelers who use specific mobile services or travel with specific vendors). Furthermore, based on a developed framework for user experience of mobile trip arrangements, the results show that a well-designed mobile site and/or native application, which preferably supports integration with other mobile services, is a must for true mobile presence. In fact, travel service providers who want to build a relationship with their customers need to consider a downloadable native application, but in order to be found through the mobile channel and make contact with potential new customers, a mobile website should be available. Moreover, we have made a first attempt with cluster analysis to identify user categories of mobile services in a travel and tourism context. The following four categories were identified: info-seekers, checkers, bookers and all-rounders. For example “all-rounders”, represented primarily by individuals who use their pocket device for almost any of the investigated mobile travel services, constituted primarily of 23 to 50 year old males with high travel frequency and great online experience. The results also indicate that travel service providers will increasingly become multi-channel providers. To manage multiple online channels, closely integrated and hybrid online platforms for different devices, supporting all steps in a traveler process should be considered. It could be useful for travel service providers to focus more on developing browser-based mobile services (HTML5-solutions) than native applications that work only with specific operating systems and for specific devices. Based on an action research study and utilizing a holistic business model framework called STOF we found that HTML5 as an emerging platform, at least for now, has some limitations regarding the development of the user experience and monetizing the application. In fact, a native application store (e.g. Google Play) may be a key mediator in the adoption of mobile travel and tourism services both from a traveler and a service provider perspective. Moreover, it must be remembered that many device and mobile operating system developers want service providers to specifically create services for their platforms and see native applications as a strategic advantage to sell more devices of a certain kind. The mobile telecom industry has moved into a battle of ecosystems where device makers, developers of operating systems and service developers are to some extent forced to choose their development platforms.

Uusien tuotantotapojen haasteet : esimerkkitapauksina mobiili-TV ja monimediaisuus YLE Uutisissa

Opinnäytetyön tavoitteena oli selvittää, millaisia ovat uusien tuotantotapojen haasteet uudenlaiselle sisällöntuotannolle ja uutisympäristölle. Monimediaisen tuotannon esimerkkitapauksiksi rajattiin mobiili-TV ja YLE Uutiset. Mobiili-TV:n tutkimusta varten kootulle testiryhmälle tehtiin subjektiivisen laadun kokemista mittaava MOS-testi (Mean Opinion Score), jossa selvitettiin testattavien mielipiteitä matkapuhelimen kautta esitettyjen videotiedostojen kuvan- ja äänenlaadusta sekä eri pakkaustapojen käyttökelpoisuudesta mobiili-TV:ssä. Testillä haettiin esille myös sisällöllisesti sopiva ja käyttökelpoinen suhde, jolla mobiili-TV:n lähetteen kokonaiskaistanleveys olisi kuvan ja äänen välillä hyvä jakaa. Lisäksi samalla testiryhmällä tutkittiin, mitä mobiili-TV:stä yleensä tiedetään, millaisena palvelu koetaan ja millaista sisältöä siihen kaivattaisiin. Tämän kuluttajatutkimuksen mukaan mobiili-TV:hen soveltuvimmiksi sisältötyypeiksi koettiin uutiset, ajankohtaisohjelmat ja osin urheilu. Mobiili-TV:ssä ei ole vielä paljoakaan tarjontaa, joten väline on suurelle yleisölle oikeastaan täysin tuntematon. Testiryhmän mielestä se voisi kuitenkin joissakin tilanteissa korvata tai täydentää perinteisen TV-vastaanottimen käyttöä. Mobiili-TV:n sisältötyyppitutkimuksen lisäksi tutkittiin YLE Uutisten sisällöntuotantomenettelyjä. Teemahaastattelujen avulla selvitettiin, millainen on toimituksen tuotantotapa, miten ylivälineellinen sisällöntuotanto siellä mahdollisesti toteutuu, millainen on sen mahdollinen mobiili-TV-palvelu ja miten siellä suhtaudutaan niin sanottuun kansalaisjournalismiin. Haastattelujen johtopäätöksinä YLE Uutisissa ei vielä toteudu aito ylivälineellinen tuotanto, mutta merkkejä muutoksesta on näkyvissä. Kansalaisjournalismin nousu on havaittu, mutta käytännön vastauksia siihen ei vielä ole. YLE Uutisten nykyinen 3G-matkapuhelimillakin käytettävä internet-TV-palvelu on toteutettu suoratoistopalveluna (engl. streaming), eikä vielä DVB-H-verkkotekniikkaa hyödyntäen, joten se on teknisesti melko matalalaatuista. Esimerkkinä toteutuneesta ylivälineellisestä tuotannosta on opinnäytetyössä esitelty Kansainvälisen Jean Sibelius -viulukilpailun monimediainen uutispalvelu. Lopuksi esitetään tutkimuksen pohjalta löytyneitä mahdollisuuksia, jotka tukevat YLE Uutisten tuotannon järjestämistä ylivälineelliseksi ja kansalaisten sisällöntuotantoa. aktivoivaksi.

Tutkimuksessa on selitetty MegaFonin ennustamis- ja lähestymistavat, joilla on valotettu todellista markkinatilannetta. Tämän tutkielman informaatio on kerätty useista lähteistä, kuten: yleistä aiheeseen liittyvää kirjallisuutta, sisäisiä raportteja ja Megafonin materiaalia, yhteistyökumppaneiden aineistoa, Internettia ja muuta saatavilla olevaa materiaalia. Tuloksena on määritelty päätöksenteon avainkohdat ja osaltaan perinteiset lähestymistavat on kyseenalaistettu.

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.

Mobile Marketing in Japan

Mobiilimarkkinoinnin markkinat ovat vasta rakentumassa ja suurin osa alan toimijoista etenkin Suomessa yrittää vielä löytää rooliaan. Sen sijaan Japanissa sisällöntuotantoliiketoiminta matkapuhelimille kukoistaa ja mobiilimarkkinointi on jo saavuttanut merkittävän aseman mobiili-internetin palvelutarjonnassa. Toisin kuin Suomessa, jossa mobiilimarkkinat ovat vielä lastenkengissä, Japanissa myös mobiilimarkkinoinnin arvoketju on vähitellen muotoutumassa.Tämän tutkimuksen tavoitteena oli antaa käsitys Japanin mobiilimarkkinoinnin dynamiikasta ja luoda viitekehys operaattorin tulevalle roolille mobiilimarkkinoinnin markkinoiden rakentamisessa. Tutkimus on deskriptiivinen ja aineisto on kerätty alan kirjallisuudesta sekä haastattelemalla tärkeitä mobiilimarkkinoiden toimijoita Japanissa. Japanissa operaattoreilla (NTT DoCoMo, J-Phone ja KDDI) on erittäin vahva asema mobiili-internetin ja mobiilimarkkinoinnin markkinoilla. Ne hallitsevat asiakasrajapintaa, päättävät mobiiliverkon ja matkapuhelimien ominaisuuksista sekä siitä, ketkä sisällöntuottajista pääsevät osaksi heidän laskutusjärjestelmäänsä. Markkinoinnissa operaattoreilla ei ole yhtä näkyvää roolia. Omistussuhteiden kautta ne kuitenkin vaikuttavat lähes koko arvoketjuun. Operaattorit ovat yhdessä Japanin suurimpien mainostoimistojen kanssa luoneet tytäryhtiöitä, jotka hoitavat mainonnan operaattorin mobiiliportaalissa. Japanissa operaattori on ottanut hallitsevan roolin mobiilimarkkinoiden rakentamisessa. Tiivis yhteistyö eri toimijoiden, kuten matkapuhelinvalmistajien, sisällöntuottajien ja mainostoimistojen kanssa, on mahdollistanut kokonaisvaltaisen palvelupaketin tarjoamisen. Palvelupaketti sisältää käyttäjäystävällisen liittymän mobiili-internetiin sekä edulliset puhelimet. Juuri tiivis yhteistyö onkin ollut yksi tärkeimmistä menestystekijöistä Japanin markkinoita rakennettaessa. Mobiilimarkkinoita rakennettaessa operaattorilla on merkittävä rooli markkinoiden muodostajana ja sisällön kokoojana. Operaattorien tulee varautua roskapostin vastaiseen taisteluun, jos sähköpostia annetaan lähettää suoraan matkapuhelimeen. On erityisen tärkeää varmistaa, ettei käyttäjien tarvitse kärsiä roskapostista, muuten suoramarkkinoinnin mahdollisuus matkapuhelimeen menetetään. Ainoastaan aktiivisella edistämisellä ja osallistumisella mobiili-internetin sisällöntuotanto- ja markkinointiliiketoimintaan operaattori voi vahvistaa markkina-asemaansa ja varmistaa osuutensa tulevista markkinoista.

Measuring mobile WAP protocol based services

WAP tulee olemaan tulevaisuudessa tärkeässä roolissa, kun etsitään sopivaa tiedonsiirtoprotokollaa uusille mobiilipalveluille. Vaikka WAP jollain tavalla epäonnistui ensimmäisessä tulemisessaan sen suosio varmasti tulevaisuudessa tulee kasvamaan. WAP:in heikko suosio ei johtunut niinkään protokollan tiedonsiirto ominaisuuksista, vaan WAP-palveluiden kehittymättömyydestä. Tulevaisuuden palvelut kuitenkin ovat kehittyneempiä ja WAP:in suosio tulee kasvamaan. Viimeisimpänä WAP:ia käyttävänä palveluna on esitelty MMS. Kun uudet WAP:iin pohjautuvat palvelut yleistyvät, asettaa se uusia vaatimuksia myös WAP gateway:lle. Työssä tarkastellaan erilaisia mahdollisuuksia mitata mobiilisti WAP palvelujen palvelun tasoa. Työssä myös toteutetaan mobiili WAP palveluiden mittauskomponentti, joka toimii osana laajempaa ohjelmistoa. Tarkoituksena on toteuttaa mittauskomponentti, joka emuloi mahdollisimman hyvin todellista loppukäyttäjää.

On Transmission System Design for Wireless Broadcasting

This thesis considers aspects related to the design and standardisation of transmission systems for wireless broadcasting, comprising terrestrial and mobile reception. The purpose is to identify which factors influence the technical decisions and what issues could be better considered in the design process in order to assess different use cases, service scenarios and end-user quality. Further, the necessity of cross-layer optimisation for efficient data transmission is emphasised and means to take this into consideration are suggested. The work is mainly related terrestrial and mobile digital video broadcasting systems but many of the findings can be generalised also to other transmission systems and design processes. The work has led to three main conclusions. First, it is discovered that there are no sufficiently accurate error criteria for measuring the subjective perceived audiovisual quality that could be utilised in transmission system design. Means for designing new error criteria for mobile TV (television) services are suggested and similar work related to other services is recommended. Second, it is suggested that in addition to commercial requirements there should be technical requirements setting the frame work for the design process of a new transmission system. The technical requirements should include the assessed reception conditions, technical quality of service and service functionalities. Reception conditions comprise radio channel models, receiver types and antenna types. Technical quality of service consists of bandwidth, timeliness and reliability. Of these, the thesis focuses on radio channel models and errorcriteria (reliability) as two of the most important design challenges and provides means to optimise transmission parameters based on these. Third, the thesis argues that the most favourable development for wireless broadcasting would be a single system suitable for all scenarios of wireless broadcasting. It is claimed that there are no major technical obstacles to achieve this and that the recently published second generation digital terrestrial television broadcasting system provides a good basis. The challenges and opportunities of a universal wireless broadcasting system are discussed mainly from technical but briefly also from commercial and regulatory aspect

Lotus Dominon käyttö Mobiilihakemisto-palvelussa

In this thesis I researched different possibilities to get calendar information via Internet in Lotus Domino server and how to apply this information in practice. Sonera Mobile Folder service supports Microsoft Exchange email server and Sonera wants to extend the support to Lotus Domino email server system. The aim of the work is to sign in to Lotus Domino server with a wanted user identifier and find this user's calendar and free/busy information. The best solution to find the wanted information is to use Domino Web Access via Internet browser. This way the wanted information is in standard XML form and it is easy to parse in to a wanted shape. You can also get extra benefits by using this kind of Web Access because often the firewalls of the companies do not block incoming service requests in HTTP-port. This means that users do not need to change the settings of the company system. In this thesis there is also an introduction of the current Mobile Folder and it is compared to other services similar to it.

Pico Cell Integration to Operator’s Incident Management Process

Mobile network coverage is traditionally provided by outdoor macro base stations, which have a long range and serve several of customers. Due to modern passive houses and tightening construction legislation, mobile network service is deteriorated in many indoor locations. Typically, solutions for indoor coverage problem are expensive and demand actions from the mobile operator. Due to these, superior solutions are constantly researched. The solution presented in this thesis is based on Small Cell technology. Small Cells are low power access nodes designed to provide voice and data services.. This thesis concentrates on a specific Small Cell solution, which is called a Pico Cell. The problem regarding Pico Cells and Small Cells in general is that they are a new technological solution for the mobile operator, and the possible problem sources and incidents are not properly mapped. The purpose of this thesis is to figure out the possible problems in the Pico Cell deployment and how they could be solved within the operator’s incident management process. The research in the thesis is carried out with a literature research and a case study. The possible problems are investigated through lab testing. Pico Cell automated deployment process was tested in the lab environment and its proper functionality is confirmed. The related network elements were also tested and examined, and the emerged problems are resolvable. Operators existing incident management process can be used for Pico Cell troubleshooting with minor updates. Certain pre-requirements have to be met before Pico Cell deployment can be considered. The main contribution of this thesis is the Pico Cell integrated incident management process. The presented solution works in theory and solves the problems found during the lab testing. The limitations in the customer service level were solved by adding the necessary tools and by designing a working question pattern. Process structures for automated network discovery and pico specific radio parameter planning were also added for the mobile network management layer..

Service Description Creation Empowerment to Mobile End Users

Increasing usage of Web Services has been result of efforts to automate Web Services discovery and interoperability. The Semantic Web Service descriptions create basis for automatic Web Service information management tasks such as discovery and interoperability. The discussion of opportunities enabled by service descriptions have arisen in recent years. The end user has been considered only as a consumer of services and information sharing occurred from one service provider to public in service distribution. The social networking has changed the nature of services. The end user cannot be seen anymore only as service consumer, because by enabling semantically rich environment and right tools, the end user will be in the future the producer of services. This study investigates the ways to provide for end users the empowerment to create service descriptions on mobile device. Special focus is given to the changed role of the end user in service creation. In addition, the Web Services technologies are presented as well as different Semantic Web Service description approaches are compared. The main focus in the study is to investigate tools and techniques to enable service description creation and semantic information management on mobile device.

The Usage of Microsoft Push Notification Service on Mobile Devices

Along with the increasing in demand of mobile computing, Push Notification (PN) is widely used in mobile phones and other devices. PN allows the developer to send messages to the end users even when the client application is not running at the moment. This solves the problem produced by non-supported multi-tasking feature as well as saving battery life. Microsoft Push Notification Service (MPNS) is one solution to use PNs in Windows Phones. The thesis gives the developers an idea of how to use PNs by introducing MPNS, comparing MPNS with other Push Notification Services, usage of different PN types analysis, and PN simulation system implementation.
