Abstract
An method for a wireless station to select an access point among a plurality of access point possibilities using a combination of characteristics about each access point such as signal strength, access point load, protocol, maximum throughput, multi-user MIMO capability, and channel load.
Claims15
A method to be performed at a station to access a Wireless Local Area Network (WLAN), the method comprising:
- determining, according to a benefit function, a plurality of access point scores corresponding to a plurality of access points giving access to the WLAN, the benefit function based on a scoring mechanism to assign weights to three or more qualities corresponding to an access point, the three or more qualities corresponding to the access point comprising at least three qualities selected from the group consisting of signal strength, a load of the access point, a load of other access points on the same wireless channel as the access point, a number of access points on the same wireless channel as the access point, a maximum data rate of a connection to the access point, protocols supported by the access point, and security protocols supported by the access point;
- and
- determining a selected access point for network access, the selected access point with a highest access point score of the plurality of access point scores.
A method to be performed at a station to select access points on multiple networks, the method comprising:
- determining, according to a benefit function, a plurality of access point scores corresponding to a plurality of access points giving access to a plurality of Wireless Local Area Networks (WLANs), the benefit function based on a scoring mechanism that assigns a weights to three or more qualities corresponding to an access point, the three or more qualities corresponding to the access point comprising at least three qualities selected from the group consisting of signal strength, a load of the access point, a load of other access points on the same wireless channel as the access point, a number of access points on the same wireless channel as the access point, a maximum data rate of a connection to the access point, protocols supported by the access point, security protocols supported by the access point, and one or more other noise sources on the same wireless channel as the access point;
- and
- determining a selected access point for network access, the selected access point with a highest access point score of the plurality of access point scores.
An apparatus for use by a station to access a Wireless Local Area Network (WLAN), the apparatus comprising:
- a processor configured to:
- determine, according to a benefit function, a plurality of access point scores corresponding to a plurality of access points giving access to the WLAN, the benefit function based on a scoring mechanism to assign weights to three or more qualities corresponding to an access point, the three or more qualities corresponding to the access point comprising at least three qualities selected from a group consisting of signal strength, a load of the access point, a load of other access points on the same wireless channel as the access point, a number of access points on the same wireless channel as the access point, a maximum data rate of a connection to the access point, protocols supported by the access point, and security protocols supported by the access point;
- and
- determine a selected access point for network access, the selected access point with a highest access point score of the plurality of access point scores.
