Universal Mobile Telecommunications System (UMTS) is the European third generation (3G) mobile system. By the end of 2004 all Swiss mobile operators will have their UMTS-Networks installed. Following services are supported by UMTS:

• Voice-Services (push-to-talk, voice-mail, telephone-conferencing) - Data-Services (m-commerce, e-mail, internet, intranet) - Multimedia-Services (video-conferencing, video-clip, video-phone)

In an empirical survey eight in Switzerland active companies were asked which UMTS-business-services business-customers would be interested in or were wanted. These companies come from the following business-areas: industry, trade, service and public services. For the random check consultation a questionnaire was created, which was discussed and worked through together with the surveyed company. The questionnaire contained following questions:

• Location allocation (e.g. Where is being worked?) - Mobile communication (e.g. Which technologies/devices used?) - UMTS in general (e.g. UMTS - level of awareness?) - Desired business-services (e.g. Which business-services are needed?) - Costs (e.g. Willingness to pay?/What kind of billing-method?)

Through the segmentation of the Swiss business market, based on business-areas of the Swiss Systematic of Economic Sectors (NOGA), new business-area specific business services could be compiled and a rough segmentation of the Swiss business market was made.

Furthermore the business model and value chain of our associated company sunrise was analyzed. By means of a SWOT analysis current and future positions of sunrise?s value chain as UMTS-operator in Switzerland were pointed out.

It is evident from this diploma thesis, that data-services (e.g. e-mail, web-services) will gain on importance in the near future, although voice-services are still the most used business-services.
