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.
Claims20
A method for registration and authentication of a mobile node of a home network on a foreign network, comprising:
- performing communication, by the mobile node on the foreign network, of at least part of an initial message sequence comprising communication between a mobile node, foreign agent of the foreign network, and one or more Authentication, Authorization and Accounting (AAA) servers;
- transmitting, by the mobile node on the foreign network after the initial message sequence, a registration request message to a home agent on the home network, wherein the registration request message is transmitted via the foreign agent on the foreign network, wherein the foreign agent is configured to forward the registration request message from the mobile node without transmission to one or more of the AAA servers to confirm authentication of the mobile node in response to the registration request message, and wherein the home agent is configured to exchange messages to confirm the authentication of the mobile node, based on receipt of the registration request message from the mobile node via the foreign agent, with at least one AAA server of the home network of the mobile node;
- and
- receive a registration response from the home agent via the foreign agent.
A method for registration and authentication of a mobile node of a home network on a foreign network, comprising:
- transmitting a registration request message to a home agent on the home network, wherein the registration request message is transmitted via a foreign agent on the foreign network, wherein the foreign agent is configured to forward the registration request message from the mobile node without transmission to one or more Authentication, Authorization and Accounting (AAA) servers to confirm authentication of the mobile node in response to the registration request message, and wherein the home agent is configured to exchange messages to confirm the authentication of the mobile node, based on receipt of the registration request message from the mobile node via the foreign agent, with at least one AAA server of the home network of the mobile node;
- and
- receiving a registration response from the home agent via the foreign agent.
An apparatus, comprising:
- a memory;
- and
- a processor in communication with the memory, wherein the processor is configured to:
- generate instructions to transmit a registration request message to a home agent on a home network, wherein the registration request message is transmitted via a foreign agent on a foreign network, wherein the foreign agent is configured to forward the registration request message from a mobile node associated with the apparatus without transmission to one or more Authentication, Authorization and Accounting (AAA) servers to confirm authentication of the mobile node in response to the registration request message, and wherein the home agent is configured to exchange messages to confirm the authentication of the mobile node, based on receipt of the registration request message from the mobile node via the foreign agent, with at least one AAA server of the home network of the mobile node;
- and
- receive a registration response from the home agent via the foreign agent.
