LOCALIZED INFORMATION SERVICE FOR CELLULAR NETWORKS USING MULTICAST CHANNELS

摘要

A system Is proposed for providing a localized information service using an infrastructure of a cellular communication network, the system comprising: a service source terminal arranged for transmitting a network upload message to the cellular communication network, said network upload message comprising a payload part; and a reflection entity of said cellular communication network arranged for receiving said network upload message, for generating one or more reflection messages comprising said payload part, and for sending said one or more reflection messages to at least one service destination terminal that has a predetermined spatial relationship with said service source terminal, wherein a spatial zone is defined and the system is arranged for automatically operating in a connected mode of the cellular communication network at least one of the service source terminal and the at least one service destination terminal that is inside the spatial zone.
