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.
