Method for performing location-specific services, broadcasting unit and mobile receiving device

摘要

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.

主权项

1. A method for performing location-specific services of a broadcasting unit, comprising:
receiving by a mobile receiving device, geographic area data transferred from the broadcasting unit, the geographic area data defining a plurality of geographic areas by coordinates as partial areas of a service area covered by a broadcast transmitter of the broadcasting unit, the plurality of geographic areas being setup for the location-specific services, and by: storing the geographic area data in the mobile receiving device, determining in the mobile receiving device a current geographic position of the mobile receiving device, determining by the mobile receiving device a current presence of the mobile receiving device in a geographic area from the plurality of geographic areas by determining whether the current geographical position is located in the determined geographic area defined by the geographic area data, and performing a service that is assigned to the determined geographic area in the mobile receiving device in an event of a positively determined presence of the mobile receiving device in the determined geographic area; and wherein: the geographic area data define a three-dimensional regional geographic area; a current three-dimensional position of the mobile receiving device is determined; and the current presence of the mobile receiving device in the three-dimensional regional geographic area is determined on a basis of the current three-dimensional position.
