Subscriber-specific enforcement of proxy-mobile-IP (PMIP) instead of client-mobile-IP (CMIP)
First Claim
1. A method of subscriber-specific activation of network-based mobility management, comprising:
- preparing an authentication confirmation message, which contains an activation attribute when determining an authentication server of a subscriber does not provide a common mobility key for terminal-based mobility management, the activation attribute indicating that activation of network-based mobility management is required for a mobile terminal of the subscriber that supports terminal-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 after successful authentication of the subscriber of the mobile terminal, andwherein with the terminal-based mobility management the mobile terminal supports Mobile-IP, and with the network-based mobility management the access network implements a Mobile-IP client function, andwherein receipt of an advertisement message at the mobile terminal enables terminal-based mobility management, andthe authentication client ensures that a foreign agent in the access network does not send the advertisement message to the mobile terminal when determining the authentication confirmation message contains the activation attribute that is set in association with the mobile terminal, thereby deactivating the terminal-based mobility management for the subscriber.

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.

12. 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 when determining the authentication server does not provide a common mobile key for terminal-based mobility management, the activation attribute indicating that activation of network-based mobility management is required for a mobile terminal of the subscriber that supports terminal-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 of the mobile terminal, and wherein with the terminal-based mobility management the mobile terminal supports Mobile-IP, and with the network-based mobility management the access network implements a Mobile-IP client function, and wherein receipt of an advertisement message at the mobile terminal enables terminal-based mobility management, and the authentication client ensures that a foreign agent in the access network does not send the advertisement message to the mobile terminal when determining the authentication confirmation message contains the activation attribute that is set in association with the mobile terminal, thereby deactivating the terminal-based mobility management for the subscriber. - View Dependent Claims (13, 14, 15)
