Abstract
A method for determining filter mask for the relevance testing of identifiers, which are able to be transmitted to a communication device by way of a communication network in messages, with the steps of: determining relevance identifiers relevant for the communication device, and determining irrelevance identifiers irrelevant for the communication device, determining at least on initial filter mask in each case for each relevance identifier, which is passable for the respective relevance identifier and is not passable for the irrelevance identifier, combining at least two initial filter masks as a combination filter mask, which is passable for the respective relevance identifier associated with the respective initial filter mask and testing the respective combination filter mask, same being retained instead of its respective basic initial filter masks, if all irrelevance identifiers are able to be masked with the combination filter mask or being rejected, it is passable for at least one irrelevance identifier.
