Abstract:
1. A method for forwarding short messages from a transmitter to a destination number of a receiver in Global System for Mobile Communications/Universal Mobile Telecommunication System (GSM/UMTS) mobile radio networks, wherein the destination number of the receiver is replaced by a forwarding number before the routing information needed for delivering the short message is determined, after which the routing information is determined and the short message is delivered by means of the forwarding number, characterized in the steps of: generating a short message (SMS) in a terminal of the transmitter which is intended for a terminal of the receiver; conveying the short message via the mobile radio network to a short message service center (SMSC) and temporarily storing the message; requesting a home location register (HLR) for routing information of the receiver by a mobile application part (MAP) command, and sending routing information for the short message, which is transmitted as standard from the short message service center (SMSC) to the home location register (HLR); interjecting the short message (SMS) delivery process between the short message service center (SMSC) and the home location register (HLR) by conveying the short message to an interaction function of a service node that is incorporated in the signaling path between the short message service center (SMSC) and the home location register (HLR); checking by a translation function of the service node whether a forwarding number is set up for the destination number; if this is so, directly modifying the destination number into the forwarding number by the translation function of the service node; forwarding the routing request with the forwarding number to the home location register (HLR); determining in the home location register (HLR) the routing information belonging to the forwarding number and returning this information to the service node which forwards it to the short message service center (SMCSC); and using this routing information, by the short message service center (SMSC) for conveying the short message to the forwarding number of the associated terminal of the receiver.
