Abstract: A method for controlling access to content by an Acquisition Point to Presentation Points in clusters in a domain. The AP receives from a PP an access content request comprising the PPs cluster identity and the PP's priority. The AP verifies if access is granted to a PP in the cluster and, if so, grants access to the requesting PP. If not, the AP verifies if access is granted to PPs in a maximum number of clusters. If not, the AP grants access. If the maximum is reached, the AP verifies if the requesting PP's priority is higher than the priority of every PP in another cluster. If not, access is denied; if so, the AP grants access to the requesting PP and denies access to the PPs in the cluster with the lowest priority values. An Acquisition Point is also claimed.
