Over the past years Mobile Business has gained significant progress not only because of higher transfer rates as well as advanced processing power and memory capabilities of networks and mobile devices but also because of novel location-based mobile applications which raise many expectations in the mobile market. As a result network operators start to offer their services to 3rd party application providers which fosters the development of innovative applications. However, today mobile applications are forced to operate in the restricted environment of one network operator which is rather cumbersome for the development of novel location-based mobile applications that need to exchange location data between different network operators, over different countries. In this paper we discuss a system architecture aimed for location-based services that overcomes the aforementioned deficiencies. It uses transaction pseudonyms for the exchange of sensitive data by preserving users privacy and allows the development of novel applications that are operated by 3rd party application providers accessing different network services. We show that the management of identities and pseudonyms allows even roaming users access to different kinds of location-based services.
