First Claim
Patent Images
1. A method for radio frequency identification based network access management comprising:
- providing a terminal that comprises an RFID reader;
wirelessly coupling to at least one RFID tag external to said terminal; and
initiating an authentication process whereby at least one of link layer information and IP layer information is sent from the at least one RFID tag to the terminal.

Abstract
A user terminal includes an RFID reader. When the user swipes or otherwise places the reader in proximity to a compatible RFID tag, the RFID tag sends a set of information to the terminal. This set of information contains the identifier of the preferred network point of connectivity (e.g. an IP address), as well as possible authentication information. Because of the short range, the information is not broadcast to a large audience. The information can also be encrypted, in which case only previously known keys allow the terminal to use the tags.

21. A mobile terminal, comprising a wireless transceiver, a data processor, and an RFID reader coupled to said data processor for receiving a transmission from at least one RFID tag, comprising information descriptive of at least one of link layer information and IP layer information for use by said mobile terminal for gaining access to a network.
- 22. A wireless communication system comprising a radio frequency identification based network access management system that includes a terminal that comprises a data processor and an RFID reader for being wirelessly coupled to at least one RFID tag external to said terminal, said data processor being responsive to information received via said RFID reader for initiating access to a network, said information comprising at least one of link layer information and IP layer information.
- 42. An RFID tag comprising an RF device and data storage for storing information for use by a mobile device when initiating access to a wireless network node.
