Framework of Media-Independent Pre-Authentication Improvements: Including Considerations for Failed Switching and Switchback
First Claim
Patent Images
1. A method for controlling a handoff decision related to switch back of a mobile node between a first network and a second network in a media independent pre-authentication framework, comprising:
- a) providing the mobile node with a location determination module that is configured to provide a location determination in relation to access points in neighboring networks;
b) based at least in part on an output of said location determination module, using a location-based algorithm to avoid oscillation between said first and second networks.

15. A method for mitigating effects of undesired switch back of a mobile node between a first network and a second network in a media independent pre-authentication framework, comprising:
-
a) maintaining contexts related to a first network for a period of time such that the contexts can be quickly recovered when the mobile returns to the first network;
b) having said mobile node use said contexts upon returning to said first network. - View Dependent Claims (16, 17)

18. A method for mitigating effects of undesired switch back of a mobile node between a previous network and a new network in a media independent pre-authentication framework, comprising:
- transmitting data packets to both said previous network and said new network for a period of time so as to avoid loss of packets if the mobile node moves back to said previous network from said new network.
