Abstract
A method provides subscriber-specific activation of network-based mobility management using an authentication server. According to the method, network-based mobility management is enforced, even if the mobile terminal supports terminal-based mobility management. This gives a network provider complete control over mobility management in his network, preventing configuration problems during the configuration of mobile terminals. In the method, after the successful authentication of a subscriber, the authentication server transmits an authentication confirmation message to an authentication client in an access network. The received authentication confirmation message contains an activation attribute for activating network-based mobility management, if the authentication server does not provide a common mobile key for terminal-based mobility management.

29. An authentication server for a subscriber-specific activation of network-based mobility management, comprising:
-
a preparation unit to prepare an authentication confirmation message, which contains an activation attribute if the authentication server does not provide a common mobile key for terminal-based mobility management, the activation attribute activating network-based mobility management; and a transmission unit to send the authentication confirmation message to an authentication client in an access network of the subscriber, after successful authentication of the subscriber. - View Dependent Claims (30, 31, 32)

33. A method for subscriber-specific activation of network-based mobility management, comprising:
-
preparing an authentication confirmation message, which contains an activation attribute if and only if an authentication server of a subscriber does not provide a common mobility key for terminal-based mobility management, the activation attribute activating network-based mobility management; and sending the authentication confirmation message to an authentication client in an access network, the authentication confirmation message being sent by the authentication server of the subscriber after successful authentication of the subscriber.
