<p>The present invention is a method for providing network access to a Mobile Terminal (MT) in a packet switched telecommunications network. An access-request is sent from a Gateway server to an Authentication, Authorization, and Accounting (AAA) server for requesting network access for the MT. The access-request includes an Access Point Name (APN) for identifying a selected APN and a MT identity parameter for identifying the MT. The AAA determines whether or not the MT is authorized on the selected APN. If the MT is not allowed on the selected APN, the Gateway server selects a subsequent APN from a list of selectable APNs based on a generic APN. However, if the MT is allowed on the selected APN, the AAA server sends an access-accept message for indicating to the Gateway server that the MT is allowed on the APN combination.</p> |
