Method and apparatus for IP mobility management selection

A network component comprising:

• a processor configured to implement a method comprising:
• receiving a first information about network-based IP mobility management from a network entity;
• receiving a second information about host-based IP mobility management, different from the first information, and a third authentication information from a mobile node, wherein the first information and the second information each comprises one or more supported IP mobility management protocols, the supported IP mobility management protocols including mobile IPv4, mobile IPv6, dual stack mobile IP, and proxy mobile IP;
• making a selection of an IP mobility management mechanism based only on the first information and the second information received from the network entity and the mobile node, respectively;
• and
• sending a message for selecting the IP mobility management mechanism to the network entity.

A method for IP mobility management selection in a network that includes a mobile node, a network entity, and an Authentication, Authorization and Accounting (AAA) server, the method comprising:

• the AAA server receiving a first information about network-based IP mobility management from the network entity;
• the AAA server receiving a second information about host-based IP mobility management, different from the first information, from the mobile node, wherein the first information and the second information each comprises one or more supported IP mobility management protocols, the supported IP mobility management protocols including mobile IPv4, mobile IPv6, dual stack mobile IP, and proxy mobile IP;
• the AAA server making a selection of an IP mobility management mechanism based only on the first information provided by the network entity and the second information provided by the mobile node;
• and
• the AAA server sending the selection of the IP mobility management mechanism to the network entity.

A communication network system having capability for IP mobility management selection, comprising:

• an Authentication, Authorization and Accounting (AAA) server configured to receive a second information about host-based IP mobility management from a mobile node;
• and
• a network entity, configured to provide a first information about network-based IP mobility management, different from the second information, to the AAA server,
• wherein the first information and the second information each comprises one or more supported IP mobility management protocols, the supported IP mobility management protocols including mobile IPv4, mobile IPv6, dual stack mobile IP, and proxy mobile IP;
• wherein the AAA server is configured to make a selection of an IP mobility management mechanism based solely on the first information about network-based IP mobility management provided by the network entity and the second information about host-based IP mobility management received from the mobile node, and to send the selection to the network entity.
