Abstract:
uring the last years an "e-Commerce" surge has swached over Europe. It has caused new businessmodels and -practices. There is no telling when it will stop. Causes which explain these increases are on the one hand the enormous amounts that are invested in the UMTS licenses by telecommunication-enterprises and on the other hand the immense dissemination and acceptance of wireless devices. Location sensitive, personalized multimedial information is provided to the users of the these features.
The term "Location Based Services" collects various location sensitive services. Knowing the position of the wireless device the providers of services are able to make services and information available to the users. The advantage of these services and information can be enhanced by personalization.
Personalization of information is the possibility of adapting the information to specific purposes and needs of the users. These needs can be collected and processed through personalization which represents a various number of technologies and applications. There is a large number of characteristics which can be added to personalization. It can be extended from the simple display of the user´s name on the WAP-site to complicated lists of navigation or models which are tailored to the special needs of the user.
Possible use of personalized location based services (PLBS) can be demonstrated by scenarios. This implies a differentiation between the fields business to consumer (B2C) and business to business (B2B) and distinguishing the scenarios between their sensitiveness in the delay of time of providing the information.
In technical view these location based services combine functions of determining the user´s position of a wireless device, for example by means of satellite Global Positioning Systems (GPS), and his availability by wireless network technologies.
