The present invention relates to a method, system, network element and computer program product for transmitting a data stream in a point-to-multipoint mode from a source entity to a plurality of users in a predetermined area of a cellular network, said predetermined area comprising a plurality of sub-areas. A predetermined, recurring time period is allocated to transmission of localized data specified for users of individual ones of said plurality of sub-areas, and a transmission capacity of the data stream is divided using said predetermined, recurring time period among adjacent sub-areas. Localized data is then transmitted during the predetermined, recurring time period using a divided transmission capacity allocated to the respective sub-area. Thereby, combination of global and local broadcast or multicast content is enabled in a broadcast system by avoiding overlapping of transmissions with different content at cell edges. |
