IP mobility support using proxy mobile node registration
First Claim
1. A method for performing mobile node registration of a terminal device which is coupled to a wireless communication device, said method comprising the steps of:
- signaling, from said terminal device, a need for mobile data services; and
initiating, in said wireless communication device, mobile node registration of said terminal device in response to said signaling step;
wherein said signaling step comprises transmitting packetized data from said terminal device to said wireless communication device, and wherein said initiating step further comprises the steps of;
monitoring, in said wireless communication device, said packetized data for an Internet Protocol (IP) address contained in an IP address request; and
initiating, in said wireless communication device, mobile node registration using said IP address if said IP address request is for a static IP address.

Abstract
A system and method for performing mobile node registration. The system comprises a terminal device for transmitting packetized data, and a wireless communication device coupled to said terminal device for monitoring said packetized data for an Internet Protocol (IP) address contained in an IP address request. The wireless communication device initiates mobile node registration using said IP address if said IP address request is for a static IP address. The wireless communication device prevents the terminal device from sending or receiving packetized data when initiating mobile node registration, and allows said terminal device to send and received packetized data upon completion of mobile node registration. As a result, the mobile node registration occurs transparently to the terminal device, obviating the need for the terminal device to have its own Mobile IP support.

6. A system for performing mobile node registration, the system comprising:
-
a terminal device for signaling a need for mobile data services; and
a wireless communication device for initiating mobile node registration of said terminal device in response to said signaling;
wherein said terminal device signals said need for mobile data services by transmitting packetized data, and wherein said wireless communication device monitors said packetized data for an Internet Protocol (LIP address contained in an IP address request, and initiates mobile node registration using said IP address if said IP address request is for a static IP address.- View Dependent Claims (7, 8, 9, 10)
