Method and apparatus for redirecting messages from a mobile terminal

The invention provides a method and an apparatus for redirecting messages from a terminal GH, in particular of a mobile terminal of a first network provider, which is connected via a gateway node GMS a second network provider to an access network ASN. In the exchanged messages are in each case network access identifiers NAI, consisting of a character string for identification of the terminal GH and a character string for addressing a server of the network provider. The Netzwerkzugriffidentifizierer NAI is reformatted in the inventive process such that the messages are not initially transmitted to the server AAA-GH of the first network provider, but first to the server AAA GMS of the second network provider. After evaluation of the data contained in the messages, the messages are passed through to the server AAA-GH of the first network provider then after consultation formatting of network access identifiers NAI.
