Up to now, location based services (LBS) in telecommunications network environments are available while only being narrowly linked to the underlying network technology or access technology. This contrasts with the supply of internet applications and the demand for LBS by clients and third parties. The novel methods, also under security & billing aspects, should cover the need of even the operators and accelerate the economical implementation of LBS for networks of the next generation. The invention relates to LBS that, by using XML protocols, permit registration on servers and logging off. These servers can be part of a public key infrastructure, whereby the management of the locations, which are specified at least geographically by degree of latitude and degree of longitude, of the availability of web services occurs as an extension of public key management methods. According to the novel methods, LBS should be able to be used by clients in transit, for example, in vehicles but also in a virtual home environment in a manner that is independent of networks, platforms and programming languages. |
