摘要:
The invention relates to method for producing a link between a person requesting a service (Client) and a service provider (Server) 3 in a decentralized mobile radio network with a service/service provider search service (Service Discovery) wherein the person requesting the service (Client) sends a Service Discovery Request in the form of a multicast message to locally adjacent stations of the decentralized mobile radio network in order to localize an as yet unknown service provider (Server) who can provide the desired service, said stations being IP routers, and said stations forward the multicast message to neighboring stations thereof before finally forwarding it to the service provider (Server) who replies with a Service Discovery Reply. The message is characterized in that the routing information of the Service Discovery Request and the Service Discovery Reply are added to the routing tables of the stations in order to retrace the way back to the person requiring the service (Client).
摘要:
A mobile communication terminal operatively coupled to at least two mobile radio communication systems in respectively associated mobile radio networks, each of which provides a user of the communication terminal with a number of services of different type. The user may thus effect efficient management of the services provided for him by virtue of the communication terminal being designed to receive and effect further processing of data records which are associated with one respective type of the services.

摘要:
The present invention relates to a method for the transmission of data in a multi-carrier system, provided with a frequency band, the carrier frequencies of which are distributed in a sub-carrier band, dividing the frequency band. On the transmission side, dependent on current transmission properties, an adaptive pre-emphasis of the transmission signal is carried out for a part of the carrier frequencies in the sub-carrier band. The transmitter thus has the capacity to determine current transmission properties as well as adaptive pre-emphasis of a part of the carrier frequencies in the sub-carrier band of the transmission signal.
