Abstract

In various embodiments, methods and systems are provided for acquiring a mobile internet protocol address in a communication network. In an embodiment, a mobile network internet node key is sent to a service node. A mobile network internet node sends a mobile internet protocol access request message to an authentication node. The authentication node can then receive the mobile network internet node key transferred from the service node. In response to receiving a mobile internet protocol access accept message at the mobile network internet node transferred from the authentication node where the mobile internet protocol access accept message comprises the mobile network internet node key, the mobile internet protocol address is assigned at the mobile network internet node to a mobile station associated with a user identifier.

Claims

1. A method for obtaining a mobile internet protocol (MIP) address, comprising:

receiving, at a service node, a mobile internet node key, wherein the mobile internet node key is generated and transmitted to the service node based on a received data link request;

retrieving, by an authentication node and in response to an MIP access request, the mobile internet node key from the service node;

receiving at a mobile network internet node from the authentication node a MIP access accept message comprising the mobile network internet node key; and

assigning a MIP address to a mobile station at the mobile internet node in response to receiving the MIP access accept message.

2. The method of claim 1, further comprising:

generating the mobile network internet node key at a second authentication node in response to a data link request received from the mobile station.

3. The method of claim 2, further comprising:

providing the generated mobile network internet node key from the second authentication to the service node.

4. The method of claim 1, further comprising:

sending a MIP reply message to a gateway node from the mobile network internet node wherein the MIP reply comprises the MIP address.

5. The method of claim 4, further comprising:

sending a MIP session accept message from the gateway node to the mobile station wherein the MIP session accept message comprises the MIP address.

6. A system for obtaining a mobile internet protocol (MIP) address, comprising:

a service node configured to;

receive a mobile internet node key, wherein the mobile internet node key is generated and transmitted to the service node based on a received data link request;

a first authentication node, configured to;

retrieve, in response to a MIP access request, the mobile internet node key from the service node; and

provide a MIP access accept message comprising a the mobile network internet node key; and

a mobile network internet node, configured to

receive from the authentication node the MIP access accept message; and

assign a MIP address to a mobile station at the mobile internet node in response to receiving the MIP access accept message.

7. The system of claim 6, further comprising:

a second authentication node, configured to generate the mobile network internet node key in response to a data link request received from the mobile station.

8. The method of claim 7, wherein the second authentication node is further configured to provide the generated mobile network internet node key to the service node.

9. The method of claim 6, further comprising:

a gateway node, to receive a MIP reply message,

wherein the mobile network internet node is further configured to send a MIP reply message to the gateway node wherein the MIP reply comprises the MIP address.

10. The method of claim 9, wherein the gateway node is further configured to send a MIP session accept message to the mobile station wherein the MIP session accept message comprises the MIP address.
