Firewall protection for wireless users
First Claim
1. A method of protecting a mobile wireless user via a firewall comprising:
- defining a mobile user profile indicative of a firewall configuration corresponding to the mobile user;
establishing the firewall configuration at a firewall application in a wireless transceiver corresponding to the current location of the mobile user, the wireless transceiver operable for wireless communication with the mobile user via a wireless access unit; and
establishing the same firewall configuration at a firewall application in a second wireless transceiver when the user is located in the area corresponding to the second wireless transceiver.

Abstract
In a computer telecommunications network, firewalls protect a machine or network from undesired message transmissions. In the case of a firewall employed on a user side of the wireless link, a message rejected by the firewall has already consumed the wireless resources required to transmit. A system for protecting a mobile wireless user via a firewall employed at the wired line, or ISP side, of the wireless link in a wireless network allows a specific user profile to be provided for each user that is indicative of a desired firewall configuration corresponding to the mobile user. A firewall configuration is established at a firewall application in a wireless transceiver corresponding to the current location of the mobile user, and the same firewall configuration is established, via a wireless handoff, at a second wireless transceiver when the user is located in the area corresponding to the second wireless transceiver, thereby protecting a plurality of wireless users prior to wasteful wireless transmission of undesired messages.

27. A method of protecting mobile wireless users via a firewall comprising:
-
defining a first mobile user profile indicative of a first firewall configuration corresponding to the first mobile user; establishing the firewall configuration at a firewall application in a base station; defining a second mobile user profile indicative of a second firewall configuration corresponding to a second mobile user; establishing the second firewall configuration at the firewall application in the base station; receiving message packets at the base station; when the message packets are directed to the first mobile user, determining, according to the first mobile user profile, whether to forward the message packets to the first mobile user; and when the message packets are directed to the second mobile user, determining, according to the second mobile user profile, whether to forward message packets directed to the second mobile user. - View Dependent Claims (28)
