In order to perform location-specific services of a broadcasting unit (3), virtual cells (22, 23, 24) for the location-specific services are set up so that cell data, which define a local cell area, are transmitted to a mobile receiving device (1) via the broadcasting unit (3). The cell data are stored in the mobile receiving device (1). The mobile receiving device (1) establishes its current position (25) and determines whether it is located in the cell area. In the event the mobile receiving device (1) is located in the cell area, the receiving device performs a service assigned to the cell data. The setting up of cells (22, 23, 24) for local-specific services by the broadcasting unit (3) in a multitude of mobile receiving devices (1) in the service area (2) of the broadcasting unit (3) enables geographical areas inside and outside the service area (2) to be split up into smaller, interactive and virtual service cells and cell clusters in a dynamic and optimal manner according to need and geographical and/or service-specific parameters. |
