Patent number: 8302148Abstract: To improve transmission of digital broadcast information, there is proposed a method of transmitting digital broadcast information from a main transmitter (12) to at least one repeater (14). There is generated a composite digital broadcast signal carrying first digital broadcast information according to a first digital broadcast specification (DVB-T) and second digital broadcast information according to a second digital broadcast specification (DVB-H). The composite digital broadcast is then broadcasted such that the second digital broadcast information (DVB-H) is sent in a transmission mode used for transmission of the first digital broadcast information (DVB-T).Type: GrantFiled: December 22, 2004Date of Patent: October 30, 2012Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Jörg Huschke, Ralf Tönjes, Uwe Horn

Publication number: 20090252084Abstract: The present invention relates to a method of communicating a push-to data packet within a communications system, where the push-to packet originates from a push-to client participating in a push-to user group comprising at least two push-to clients. The method comprises receiving the push-to data packet from a push-to server and broadcasting the push-to data packet over a broadcast distribution network to broadcasting clients which are not part of the push-to user group. A communications interface arranged to communicate push-to data packets, originating from a push-to client participating in a push-to user group comprising at least two push-to clients, from a push-to server to a broadcast node arranged to broadcast the push-to data packets to broadcasting clients which are not part of the push-to user group is also disclosed.Type: ApplicationFiled: July 18, 2005Publication date: October 8, 2009Inventors: Gabor Fodor, Ralf Tönjes

Patent number: 7558262Abstract: The invention relates to a method for performing a flexible multicast of multicast data to a multicast group within a telecommunication system wherein the multicast data is provided by a broadcast/multicast server and transferred to the users registered to the multicast group by means of channels. In the invention multi-channel multicast groups (B1,B2, . . . ) are provided. Each multi-channel multicast group offers at least one channel wherein a channel transports content. The availability and configuration of the multi-channel multicast group is announced to the users by means of an announcement multicast group (A). The user either initiates the changing to an announced multi channel multicast group or the user is forced by the operator to change in case the operator wants to control the allocation of resources.Type: GrantFiled: November 29, 2002Date of Patent: July 7, 2009Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Ralf Tönjes, Ralf Keller, Thorsten Lohmar, Frank Hundscheidt

Patent number: 7366517Abstract: Method of arranging a cellular radio network in a geographical area which is already covered by an existing cellular radio network, wherein cell clusters of the cellular radio network to be introduced and using a specific transmission frequency are located in areas determined by connecting at least two cells of the existing cellular radio network using the specific transmission frequency, and wherein the cell clusters are arranged such that they do not overlap with the cells of the existing cellular radio network. The cell clusters of the introduced cellular radio network may be adjusted by reducing the cell size of cell clusters of the introduced cellular radio network, and by introducing new cells into cell clusters of the introduced cellular radio network. The invention allows to reuse frequencies of an existing cellular radio network by an introduced cellular radio network in the same geographical area.Type: GrantFiled: July 26, 2006Date of Patent: April 29, 2008Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Ralf Keller, Ralf Tonjes, Wolfgang Stahl, Jörn Thielecke, Jörg Huschke, Udo Wachsmann
