LINK VERIFICATION IN A WIRELESS NETWORK

摘要

A method and apparatus for verifying the status of a wireless connection between a wireless device and an access point are disclosed. If the number of missed beacon frames exceeds a threshold value, the wireless device transmits a link verification request to the access point. If the wireless device receives a response to the link verification request, the wireless device may verify the connection and then retrieve downlink data from the access point. If the wireless device does not receive a response, then the wireless device may terminate the wireless connection.

主权项

1. A method of operating a wireless device associated with an access point in a wireless network, the method comprising:
counting a number of missed beacon frames corresponding to the access point; comparing the number of missed beacon frames with a threshold value; transmitting a link verification request to the access point if the number of missed beacon frames equals the threshold value; listening for a response, from the access point, to the link verification request; and selectively terminating a connection with the access point in response to the listening.
