Systems and methods for early determination of network support for mobile IP
First Claim
1. A method for a mobile node configured for communication in a wireless communication system, the method comprising:
- connecting the mobile node, via a processor in the mobile node, to a wireless network;
testing for satisfaction of any disconnect condition of a plurality of disconnect conditions, wherein each disconnect condition of the plurality of disconnect conditions is an early indication of network support for Mobile IP, wherein the step of testing comprises determining whether authentication is required by the wireless network during Link Control Protocol (LCP) negotiation, wherein determining whether authentication is required comprises indicating to the wireless network that the mobile node will not perform authentication, and wherein the step of testing is performed prior to packet network connection between the mobile node and the wireless network; and
disconnecting from the wireless network without performing authentication if authentication is required by the wireless network during LCP negotiation.

Abstract
In a wireless communication system, a method for early determination of network support for Mobile IP is disclosed. A mobile node is in communication with a wireless network. Then a test is performed for a disconnect condition wherein the disconnect condition is an early indication of network non-support for Mobile IP as identified by at least a requirement for authentication. Early indication relates to identification of the non-support for Mobile IP prior to or during network packet connection. If the disconnect condition is found, the mobile node disconnects from the wireless network. If the disconnect condition is not found, the mobile node stays connected to the wireless network.

13. A mobile node adapted to communicate in a wireless network supporting Internet Protocol (IP), the mobile node comprising:
-
a processor for executing instructions; and memory for storing the instructions, wherein the instructions test for a plurality of disconnect conditions, wherein at least one disconnect condition of the plurality of disconnect conditions is evaluated prior to packet network connection, wherein the disconnect conditions of the plurality of disconnect conditions identify network non-support for Mobile IP, wherein the at least one disconnect condition includes determination of an authentication requirement for the wireless network during Link Control Protocol (LCP) negotiation, wherein determining the authentication requirement comprises indicating to the wireless network that the mobile node will not perform authentication, wherein the instructions disconnect the mobile node from the wireless network without performing authentication if any disconnect condition of the plurality of disconnect conditions is found. - View Dependent Claims (14, 15, 16, 17)
