Abstract
The invention relates to a method for transmitting broadband, IP-based data streams in a point-to-many points communications network, based on a mobile radiotelephone network. According to said method, a universal multicast channel is installed in the cells of the mobile radiotelephone network for transmitting IP-based multicast data streams from a base station (RBS) to subscriber-end terminals (RNT).
Claims12
A method for transmitting broadband, IP-based data streams in a point-to-multipoint communications network, in which
- a universal multicast channel for the transmission of broadband, IP-based multicast data streams from a base station (RBS) to subscriber-end access devices (RNT) is provided in the radio cells of the communications network
- and subscriber-end access devices (RNT) which wish to receive register desired data streams with the base station (RBS), and the base station (RBS) tells them an identifier for the desired data streams.
The method as claimed in one of the preceding claims, in which
- information relating to a data stream which has been chosen by a subscriber-end access device (RNT) is stored in a register or in a database in a base station (RBS).
The method as claimed in one of the preceding claims, in which
- base station (RBS) marks all the IP data packets which are associated with a requested data stream by means of a header in the IP data packets before passing them on in the direction of the subscriber-end access device (RNT).
The method as claimed in one of the preceding claims, in which IP-based data streams are bundled on the multicast channel using a time-division multiplex component.
The method as claimed in one of the preceding claims, in which
- digital transmission of radio programs (Digital Audio Broadcasting) and/or television programs (Digital Video Broadcasting) take place or takes place via the multicast channel.
The method as claimed in one of the preceding claims, in which an intelligent, fixed-position agent in a base station (RBS) takes over the procurement, administration, filtering, distribution and/or billing for the data streams.
