Abstract

A system and method for invoking the performance of mobile node registration in a wireless communication network. The system comprises a terminal device for transmitting and receiving packetized data and a communication device coupled to the terminal device. The communication device monitors the packetized data for an Internet Protocol (IP) address contained in an IP address request. If the IP address request is for a static IP address the communication device waits for network movement information. Based on the received network movement information, the communication device solicits network address information. Upon receipt of the network address information, the terminal device then initiates Mobile Node registration. As a result, the Mobile Node registration is automatically invoked whenever the terminal device changes its network point-of-attachment.

Claims

1. A method for invoking mobile node registration in a wires communication network having a terminal device coupled to a mobile communication device for transmitting and receiving packetized data, said method comprising:

interfacing said mobile communication device with said wireless communication network;

receiving, by said mobile communications device, network movement information from the wireless communication network;

soliciting, by said mobile communications device, network IP address information from said wireless communication network;

receiving, by said mobile communication device, network IP address information from said wireless communication network; and

initiating, by said terminal device, mobile node registration in response to said network movement information received by said mobile communication device.

2. The method of claim 1, further including,

monitoring, by said mobile communication device, said transmitted packetized data for an IP address contained in an IP address request, and

waiting, by said mobile communication device, for network movement information if said IP address request is for a static IP address.

3. A system for automatically invoking mobile node registration in a wireless communication network, said system comprising:

a mobile communication device for interfacing over a wireless link with said wireless communication network, said mobile communication device receiving network movement information from said wireless communication network;

a terminal device, having an IP address, coupled to said mobile communication device, for transmitting and receiving packetized data associated with the IP address, wherein said terminal device initiates mobile node retraction in response to said network movement information;

wherein said mobile communication device includes means for monitoring said packetized data transmitted by said terminal device for an IP address contained in the IP request; and

wherein the IP address is a static IP address.

4. A system for automatically invoking mobile node registration in a wireless communication network, said system comprising:

a mobile communication device for interfacing over a wireless link with said wireless communication network, said mobile communication device receiving network movement information from said wireless communication network;

a terminal device, having an IP address, coupled to said mobile communication device, for transmitting and receiving packetized data associated with the IP address, wherein said terminal device initiates mobile node registration in response to said network movement information and wherein the IP address is a static IP address;

wherein said mobile communication device includes means for monitoring said packetized data transmitted by said terminal device for an IP address contained in the IP request; and

wherein the mobile communication device includes means for soliciting the wireless communication network for network IP address information in response to the network movement information.

5. A system for automatically invoking mobile node registration in a wireless communication network, comprising:

a mobile communication device for interfacing over a wireless communication link with the wireless communication network, the mobile communication device receiving network movement information from the wireless communication network; and

a terminal device, having a static IP address associated with a home agent, coupled to the mobile communication device;

wherein the terminal device, through the wireless communication link, transmits packetized data to, and receives packetized data from, an internetworking function using an Internet Protocol, and the terminal device initiates mobile node registration in response to the network movement information.

6. The system of claim 5, wherein the wireless communication network is a CDMA wireless network.

7. The system of claim 6, wherein the movement information is a change the wireless communication network system ID received by the mobile communication device.

8. The system of claim 6, wherein the movement information is a change in the wireless communication network ID received by the mobile communication device.

9. The system of claim 5, wherein the terminal device initiates mobile node registration by soliciting an agent advertisement message that identifies the home agent or one of a plurality of foreign agents.
