Abstract
A network includes access points that admit/terminate mobile station associations based upon the loading level of the access point and/or whether a mobile station can associate with a further access point. Mobile stations transmit information indicative of the access points to which they can associate. The access points determine whether to admit/terminate a mobile station association based upon access point loading.

A method of controlling access point loading in a wireless network, comprising:
- receiving, by a first one of a plurality of access points, information transmitted by a mobile station, the information including an indication of one or more access points in the plurality of access points with which the mobile station can associate, said information further including an indication that at least one of said one or more access points can associate with said mobile station using a frequency channel other than a current frequency channel used by said first access point;
- determining, by said first one of the plurality of access points, whether the mobile station can establish an association with a second one of the plurality of access points based on said received information;
- and
- determining whether to admit an association of the mobile station with the first one of the plurality of access points based upon a loading level of the first one of the plurality of access points and said determination of whether said mobile station can establish an association with said second one of the plurality of access points, wherein the first one of the plurality of access points does not receive a request for an association with the mobile station from the mobile station after denying an association with the mobile station.

An access point, comprising:
- a transceiver configured to provide communication with a mobile station over a radio link;
- a memory configured to store information including, for one or more mobile stations, with how many and with which access points each of the one or more mobile stations can associate, and an indication as to which access points said one or more mobile stations can associate with using a frequency channel other than a current frequency channel;
- and
- an association module configured to determine whether to accept an association with a mobile station based upon a loading level of the access point, the stored information, and a determination of whether said mobile station can establish an association with another access point,
- said association module further configured to not receive a reguest for an association with a mobile station from said mobile station after denying an association with said mobile station.
