Making a telephone connection to a mobile communication terminal with the calling party controlling how the call should be established

摘要

The invention relates to a method for establishing a telephone connection to a mobile communications terminal device (11) via a mobile communications network (5, 7, 9), with at least one mobile telephone number being assigned to the mobile communications terminal device (11), wherein a supplement i.e. prefix or suffix as a control parameter is added to the mobile telephone number, the supplement being independent from the mobile telephone number. Before establishing the telephone connection an analysis of this supplement is made and the reachability of the mobile communications terminal device (11) is determined. The “reachability” is that the calling party only wants to make the call if the called party is available in real time i.e. does not want to be forwarded to voice-mail. Another example is that the call should only be established for calls that remain in the same network, so as to save costs. The supplement indicates whether the establishment of a telephone connection shall be initiated or suppressed. The establishment of the telephone connection is then initiated dependent upon the supplement only if there is a certain reachability case of the called mobile communications terminal device (11), the reachability case being indicated by the supplement.
