When a mobile station (10) in a mobile telephone system is called, a check is made whether the mobile station is operatively available for answering an incoming call to the mobile station. If the mobile station is found to be unavailable for answering the call, the telephone number of the caller (11) is registered. Name information relating to the caller is retrieved from the operator (110), which provides the caller's telephone subscription. A digital text message is provided with identity information, comprising the registered telephone number and the corresponding name information, and is transmitted to the mobile station, once the mobile station becomes operatively available.
