Abstract

A method for indicating the presence of a text message in a mobile radiotelephone network if the recipient is registered as a subscriber both in the mobile radiotelephone network and in another communication network as a subscriber. It is provided that the availability of the subscriber in the other communication network is stored in the database, which is allocated to the subscriber, of the mobile radiotelephone network, and in wherein message central module communicates a message concerning the presence of a text message for the subscriber to a control module of the other communication network (PISN), and wherein this control module thereupon causes the displaying of an item of information concerning the presence of a text message in the message central module of the mobile radiotelephone network to a terminal apparatus allocated to the subscriber within the other communication network.
