METHOD AND DEVICE HAVING PRUNING MECHANISM TO IDENTIFY WIRELESS ACCESS POINTS IN MULTIPLE-SSID ENVIRONMENT
First Claim
1. A method having a pruning mechanism to identify wireless access points (APs) in multiple-SSID environment comprising:
- (A) collecting a plurality pieces of wireless signal data in an environment by an identification device;
(B) based on an information of basic service set identification (BSSID) comprised in the pieces of wireless signal data, determining that at least two pieces of the wireless signal data have the same BSSID by the identification device to keep only one of the at least two pieces of the wireless signal data, and determining at least one of the pieces of wireless signal data in which the BSSID is derived from a media access control (MAC) address of at least one of wireless APs under management based on data comprised in the pieces of wireless signal data to delete the at least one of the pieces of wireless signal data;
(C) based on information of a channel, a wireless mode, a received signal strength indicator (RSSI) and the BSSID of the remained wireless signal data after step (B), determining that at least two pieces of the remained wireless signal data have the same channel, the same wireless mode, a difference of the RSSI absolute value smaller than a first predetermined value and a hamming distance of the BSSID smaller than a second predetermined value by the identification device to keep only one of the at least two pieces of the remained wireless signal data; and
(D) based on a number of the pieces of the remained wireless signal data after step (C), determining a number of the unmanaged wireless APs that exist in the environment by the identification device, in which the number of the unmanaged wireless APs corresponds to the number of the pieces of the remained wireless signal data.

Abstract
A method having a pruning mechanism to identify wireless APs in multiple-SSID environment that includes the steps outlined below. (A) Wireless signal data in an environment are collected. (B) Only one of the at least two pieces of the wireless signal data having the same BSSID is kept and delete the at least one of the pieces of wireless signal data that has the BSSID derived from a MAC address of wireless APs under management. (C) Only one of the at least two pieces of the remained wireless signal data having the same channel, the same wireless mode, a difference of the RSSI absolute value that is smaller than a first predetermined value and a hamming distance of the BSSID that is smaller than a second predetermined value is kept. (D) Based on a number of the remained wireless signal, a number of the unmanaged wireless APs is determined.

5. A device having a pruning mechanism to identify wireless APs in multiple-SSID environment comprising:
-
a signal collecting module configured to collect a plurality pieces of wireless signal data in an environment; and a processing module configured to, based on an information of BSSID comprised in the pieces of wireless signal data, determine that at least two pieces of the wireless signal data have the same BSSID by the identification device to keep only one of the at least two pieces of the wireless signal data, to determine at least one of the pieces of wireless signal data in which the BSSID is derived from a MAC address of at least one of wireless APs under management based on data comprised in the pieces of wireless signal data to delete the at least one of the pieces of wireless signal data, based on information of a channel, a wireless mode, a received signal strength indicator (RSSI) and the BSSID of the remained wireless signal data, to determine that at least two pieces of the remained wireless signal data have the same channel, the same wireless mode, a difference of the RSSI absolute value smaller than a first predetermined value and a hamming distance of the BSSID smaller than a second predetermined value by the identification device to keep only one of the at least two pieces of the remained wireless signal data and, based on a number of the pieces of the remained wireless signal data, to determine a number of the unmanaged wireless APs that exist in the environment corresponding to the number of the pieces of the wireless signal data by the identification device. - View Dependent Claims (6, 7, 8)
