Abstract
A method for selecting a channel for an access point (AP) in a Wireless Local Area Network (WLAN). The method includes the AP receiving network conditions of APs within the sensing range of a terminal sent by the terminal, and the AP selecting a channel based on the received network conditions. By forwarding the network conditions of other APs which can be detected by the terminal, the method of the present invention enables an AP to select a channel from the view of a terminal to avoid conflicts at the terminal, thereby improving the available bandwidth of the terminal, and giving a better experience to users.
Claims18
A method for selecting a channel for an Access Point (AP) in a Wireless Local Area Network (WLAN), the method comprising:
- receiving, by the AP from a terminal, network conditions of APs that are within the sensing range of the terminal;
- and
- selecting, by the AP, a channel based on the received network conditions;
- wherein the network conditions comprise:
- (i) information on a downlink channel from an AP to the terminal that is within the sensing range of the terminal;
- or (ii) downlink channel information and traffic load information of an AP within the sensing range of the terminal.
A method for assisting an access point (AP) in selecting a channel in a Wireless Local Area Network (WLAN), comprising:
- collecting, by a terminal, network conditions of APs within the terminal's sensing range;
- and
- sending, by the terminal, the collected network conditions to the APs within the terminal's sensing range;
- wherein the network conditions comprise information on (i) a downlink channel from an AP within the sensing range of the terminal to the terminal;
- or (ii) the downlink channel information and traffic load information of an AP within the sensing range of the terminal.
An Access Point (AP) in a Wireless Local Area Network (WLAN), comprising:
- a network conditions communicator, for receiving network conditions of APs within the sensing range of a terminal sent by the terminal;
- and
- a channel optimizer, for selecting a channel based on the received network conditions, wherein the network conditions comprise:
- (i) downlink channel information from an AP within the sensing range of the terminal to the terminal;
- or
- (ii) downlink channel information and traffic load information of an AP within the sensing range of the terminal;
- Wherein the downlink channel information comprises at least one of a channel number, a channel strength and wireless mode.
