Abstract

Systems and methods are described for configuring customer premises equipment in a wireless network in response to reconnection of subscriber station to a base station. A set of rules is provided that governs configuration of a network interface based in part on whether the interface connects to a different base station after reconnection. Reconfiguration may include cycling power of the network interface and the decision to cycle power may be based on network configuration determined after the loss of communication. This decision can be made after the loss of communication and after the network interface is reconnected to the wireless network through the same or a different base station. The rules may be processed by a combination of subscriber equipment, network interface and base station. Power may be cycled responsive to a message transmitted by the one base station to the network interface.

Claims

1. A method for power cycling in a network interface, comprising:

establishing communication between a new base station of a wireless network and the network interface, the network interface having a current network address;

intercepting at the new base station incorrectly addressed data from the network interface, the intercepting occurring after the communication is established between the network interface and the new base station;

identifying a disconnection of the network interface from an old base station of the wireless network based on the new base station intercepting the incorrectly addressed data from the network interface; and

transmitting, after the identifying the disconnection, a message from the new base station to the network interface instructing the network interface to cycle power, the power cycling of the network interface comprising powering down the network interface and powering up the network interface, the power cycling of the network interface causing the network interface to request a new network address to replace the current network address, the transmitting being based on a predetermined rule that identifies a network condition for the power cycling, and the network condition including whether a first network configuration of the new base station is different from a second network configuration of the old base station.

2. The method of claim 1, wherein the network condition further includes whether the disconnection of the network interface results from fading of a signal received from the old base station.

3. The method of claim 1, wherein the power cycling is deferred for a predetermined time.

5. The method of claim 1, wherein the network condition further includes whether a signal between the network interface and the new base station meets or exceeds a predetermined minimum strength.

6. The method of claim 1, wherein the power cycling is deferred until a signal between a signal between the network interface and the new base station meets or exceeds a predetermined minimum strength.

7. The method of claim 1, wherein the message is a broadcast message.

8. The method of claim 1, wherein the transmitting the message is performed as part of the network interface registering with the new base station.

9. The method of claim 1, wherein a subscriber station comprises the network interface.

10. The method of claim 1, wherein customer premises equipment comprises the network interface.

4. A system for power cycling in a network interface, comprising:

means for establishing communication between a new base station of a wireless network and the network interface, the network interface having a current network address;

means for intercepting at the new base station incorrectly addressed data from the network interface, the intercepting occurring after the communication is established between the network interface and the new base station;

means for identifying a disconnection of the network interface from an old base station of the wireless network based on the new base station intercepting the incorrectly addressed data from the network interface; and

means for transmitting, after the identifying the disconnection, a message from the new base station to the network interface instructing the network interface to cycle power, the power cycling of the network interface comprising powering down the network interface and powering up the network interface, the power cycling of the network interface causing the network interface to request a new network address to replace the current network address, the transmitting being based on a predetermined rule that identifies a network condition for the power cycling, and the network condition including whether a first network configuration of the new base station is different from a second network configuration of the old base station.
