ABSTRACT:
The invention relates to a method for controlling the exchange of data between mobile subscribers in a packet-oriented mobile communication network, wherein management of each subscriber occurs at a specific control node (SGSN) of the mobile communication network according to the actual whereabouts of the subscriber inside the mobile communication network; links from/to a mobile communication transmitter device of the mobile subscriber are controlled inside the mobile communication network by the corresponding control node; wherein an address register comprising all of the addresses allocated to mobile subscribers managed by said control node is stored in the control network node; a destination address allocated to the data packets is read out in the control network node from incoming data packets and is compared to the address register by means of a search function; if the destination address is available in the address register, the data packets are exclusively handled by the control node in the mobile communication network and are further transmitted; if the destination address is missing in the address register, the data packets are transmitted by the control node to another network node (GGSN) of the mobile communication network for further processing.
