A method and system are provided for transmitting information in a Mobile Internet Protocol (IP) environment, which includes a home agent (HA) provided at a home network, a base station (BS) broadcasting a pilot signal, a foreign agent (FA) provided at or associated with the BS, a mobile node (MN) providing the ability to detect and identify itself to a BS, a proxy mobile node (PMN) Identifying the MN wherein the PMN is provided at the BS. If the PMN identifies the MN, the PMN retrieves an IP address for each of the MN, FA and HA and sends a registration request to the FA. The FA relays the registration request to the HA, and the proxy MN is registered with the HA. Thus, the MN functionality is provided transparently to the MN by the PMN. This significantly simplifies the configuration of the MN and the Mobile IP network.

1. A method for use in a base station comprising a mobile internet protocol (MIP) proxy node for transparently providing mobile IP services to a plurality of mobile nodes, the method comprising: receiving a signal from a mobile node;determining MIP information on behalf of the mobile node, the MIP information including an IP address of an agent associated with the mobile node;sending a registration request to the agent on behalf of and transparent to the mobile node; andreceiving MIP packets from the agent on behalf of the mobile node. 2. The method of claim 1, further comprising: transmitting the MIP packets to the mobile node. 3. The method of claim 1, further comprising: receiving the MIP packets from the agent via tunneling. 4. The method of claim 1, further comprising: identifying the mobile node as a visitor associated with a home network. 5. The method of claim 1, further comprising: monitoring a lifetime of a MIP session. 6. The method of claim 1, further comprising: monitoring a lifetime of a MIP message. 7. The method of claim 1, further comprising: deregistering the mobile node on a condition that the proxy node receives a notification indicating that the mobile node has moved to a new proxy node. 8. The method of claim 1, further comprising: identifying the mobile node based on the signal. 9. The method of claim 4, wherein the signal comprises a link layer message. 10. A base station, comprising: a mobile internet protocol (MIP) proxy node for transparently providing mobile IP services to a plurality of mobile nodes;a receiver comprising circuitry configured to receive a signal from a mobile node;circuitry configured to determine MIP information on behalf of the mobile node, the MIP information including an IP address of an agent associated with the mobile node;a transmitter comprising circuitry configured to send a registration request to the agent on behalf of and transparent to the mobile node; andthe receiver further configured to receive MIP packets from the agent on behalf of the mobile node. 11. The base station of claim 10, wherein the transmitter is further configured to transmit the MIP packets to the mobile node. 12. The base station of claim 10, wherein the receiver is further configured to receive the MIP packets from the agent via tunneling. 13. The base station of claim 10, further comprising: circuitry configured to identify the mobile node as a visitor associated with a home network. 14. The base station of claim 10, further comprising: circuitry configured to monitor a lifetime of a MIP session. 15. The base station of claim 10, further comprising: circuitry configured to monitor a lifetime of a MIP message. 16. The base station of claim 10, further comprising: circuitry configured to deregister the mobile node on a condition that the proxy node receives a notification indicating that the mobile node has moved to a new proxy node. 17. The base station of claim 10, further comprising: circuitry configured to identify the mobile node based on the signal. 18. The base station of claim 10, wherein the signal comprises a link layer message.
