摘要： A plurality of methods, computer program product, and apparatus that use a lower 32 bit field of a 64-bit 802.11 TSF timer, so as to encode the reference time instant without the ambiguity as to whether there the reference time is referring to a future time or a past time. According to an aspect of the present invention, the fact that the low order 32 bits of the TSF timer wraps over in about 71 minutes is exploited to remove any ambiguity in the reference times contained in the Schedule Element frame. One method employs an algorithm base on distance between two reference points to determine whether the timer has wrapped around a time period, and another method uses a delay interval or a timeout to determine whether or not the TSF timer is wrapped or unwrapped. Another method includes determining whether an absolute value of X-O is less than, or greater than or equal to maximum value M/2.

摘要： A plurality of methods, apparatus and computer program for providing warning to a station (STA) associated with an Access Point (AP) in a WLAN that a disassociation the AP is imminent. The steps include (a) selecting a station (STA) for disassociation from a particular Access Point (AP) of a WLAN; (b) by updating a newly created reason code field of a message to indicate to the selected STA that it has become a candidate for disassociation; and (c) transmitting the message to the selected STA. Upon receipt by the STA of a message indicating that the selected STA has become a candidate for disassociation, the selected station scans other Access Points from a list to find another Access Point to associate with before being cut off by the current Access Point.

摘要： An apparatus and method is provided for measuring medium activity patterns in wireless networks and deriving information about the radio environment from the measured medium activity/patterns. This invention is three-fold. First, it defines what to measure, including medium idle/busy patterns based on power detection, medium idle/busy pattern based on preamble detection, and medium idle/busy pattern based on virtual sensing. Second, it provides a mechanism for communicating the measurement request and report, as illustration for the case of IEEE 802.11. And last, it defines the information that can be derived given these measurements as discovery of: non-802 devices, 802.11e systems, 802.11e contention-based medium access priorities, 802.11e controlled medium access usage, 802.11b/g existence, and hidden stations.

摘要： The present invention is a system, apparatus, and method for a "Priority" field that is included in the information transmitted by an Access Point (AP) (801 i ) about its neighbor APs (801 i ) and the network service providers (SPs) that it supports. A "Priority" field (1O3 i -6 154 i .2 203.i.2 233 266) is included in at least one of a Neighbor Report element (100), an AP Channel Report element (150), and a service provider's information element (200 230 260). The service provider priority field (203.i.2 233 266) is contained in any protocol frame transmitted by the AP (801 i ) that contains information about one or more service providers that it supports. The "Priority" field (103 i .6 154- i .2 203.i.2 233 266) contains a numeric value or a symbolic indicating a recommendation from the AP (801 i ) concerning which AP/APs and service provider(s) SP/SPs for a STA (802 j ) to scan first or access in an eventual roaming/accessing process. For roaming/accessing purposes, more than one neighboring AP (801 i ) can have the same priority value and not all the APs (801 i ) that are neighbors or support SPs necessarily have the same priority value.
