Abstract
The invention consists of a new registration and authentication protocol for between a Mobile Node and a Home Agent. The new protocol uses a novel messaging sequence to request registration, authentication and authorization of the Mobile Node when it is located on a foreign network, and the novel protocol will avoid some of the standard registration and authentication protocol messages in order to eliminate the problems associated with re-transmission errors.
Claims17
A method for registration and authentication of a mobile node on a foreign network comprising:
- a foreign agent on the foreign network initiating an initial sequence of first registration messages to one or more Authentication, Authorization and Accounting (AAA) servers of a home network of the mobile node to confirm authentication of the mobile node;
- the foreign agent receiving a second registration request message from the mobile node;
- the foreign agent transmitting the second registration request message to the home agent without transmission to said one or more AAA servers if the authentication of the mobile node is confirmed by responses received by the foreign agent to the initial sequence of first registration messages;
- the foreign agent receiving a registration response to the second registration request message from the home agent upon confirmation by the home agent of the authentication of the mobile node through said one or more AAA servers;
- and
- the foreign agent transmitting the registration response to the second registration request message to the mobile node.
A communications network comprising:
- a home network having a home agent coupled to a first of one or more Authentication, Authorization and Accounting (AAA) servers;
- a foreign network having a foreign agent, the foreign network having the mobile node located thereon;
- wherein the foreign agent is configured to:
- initiate an initial message sequence between the foreign agent and the first AAA server, to confirm authentication of the mobile node;
- receive a registration request message from the mobile node after confirmation of authentication of the mobile node;
- transmit the registration request message to the home agent without transmission to said one or more AAA servers if the authentication of the mobile node is confirmed by response(s) received by the foreign agent in the initial message sequence;
- receive a response to the registration request message from the home network upon confirmation by the home agent of the authentication of the mobile node through said one or more AAA servers;
- and
- transmit the response to the registration request to the mobile node.
A non-transitory, computer accessible memory medium storing program instructions for registration and authentication of a mobile node on a foreign network, wherein the program instructions are executable by a processor of a foreign agent to:
- initiate an initial sequence of first registration messages to one or more Authentication, Authorization and Accounting (AAA) servers of a home network of the mobile node to confirm the authentication of the mobile node;
- receive a second registration request message from the mobile node;
- transmit the second registration request message to the home agent without transmission to said one or more AAA servers if the authentication of the mobile node is confirmed by responses received by the foreign agent to the initial sequence of first registration messages;
- receive a registration response to the second registration request message from the home agent upon confirmation by the home agent of the authentication of the mobile node through said one or more AAA servers;
- and
- transmit the registration response to the second registration request message to the mobile node.
