Controlling setting-up a connection in a mobile communication system includes storing, in at least one subscriber database, subscriber-oriented data for a subscriber registered in a home mobile radio network, entering the subscriber-oriented data in a subscriber database when the subscriber moves, and setting-up a connection for the subscriber with a mobile station using a mobile switching center coupled to the subscriber database.

Mobile communication system for controlling a connection setup

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.

Method and mobile radio communication network for the transmission of packet data

A method is described in which a number of subscriber profiles are flexibly allocated to a subscriber identity module. The subscriber has a subscriber identity module in his terminal. The terminal is also associated with a subscriber identity number. However, the subscriber identity number can be associated with two or more directory numbers that are distinguished by different associated subscriber profiles. The subscriber profiles are available and can be administered in a suitable manner in the network. Depending on the current status of the profile (activated/deactivated), a mobile-terminated call is switched through or diverted, e.g. to a so-called &ldquo;voice mailbox&rdquo;, that is to say an answering machine.
