    Abstract: A technique for distributing in a multicasting network media content via two or more media layers is described. The media layers are hierarchically arranged in accordance with a scalable coding protocol such as the Scalable Video Coding (SVC) protocol. In a method implementation of this technique, in a first step a first number of media recipients for a first media layer that is transmitted via a first bearer of the multicasting network is determined. Then, a second bearer of the multicasting network for at least one second media layer is selected taking into account the first number and a hierarchical relationship between the first media layer and the second media layer.

    Abstract: 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.

    Abstract: A method of dynamically re-allocating a frequency spectrum to a plurality of radio networks (RNs; 16 ) in accordance with a predefined spectrum allocation scheme is described. A spectrum resource is previously allocated to each RN ( 16 ) or group of RNs ( 16, 16 '). An electronic spectrum request for a RN ( 16 ) or a group of RNs ( 16, 16 ') is generated and transmitted via a communications network ( 18 ) to a server infrastructure ( 12 ) which also receives electronic spectrum requests for other RNs ( 16 ), the server infrastructure ( 12 ) processing the received electronic spectrum requests in accordance with the spectrum re-allocation scheme to re-allocate the spectrum resources to the plurality of RNs ( 16 ).
