<p>A method for controlling access to content by an Acquisition Point (AP; 101, 201) to Presentation Points (PPs; 102, 103, 202) in clusters (120, 130, 140) in a domain (100, 200). The AP receives (601) from a PP an access content request (107) comprising the PPs cluster identity and the PP's priority. The AP verifies (602) if access is granted to a PP in the cluster and, if so, grants access to the requesting PP (604). If not, the AP verifies (603) if access is granted to PPs in a maximum number of clusters. If not, the AP grants access (604). If the maximum is reached, the AP verifies (608) if the requesting PP's priority is higher than the priority of every PP in another cluster. If not, access is denied (609); if so, the AP grants access to the requesting PP and denies access to the PPs in the cluster with the lowest priority values (610). An Acquisition Point is also claimed.</p> |
