摘要： Methods and systems are presented for establishing communications in a wireless local area network involving obtaining at least one measurement of load for each of a plurality of access point (AP) devices, automatically selecting one of the plurality of AP devices as a selected AP device by taking into account the at least one measurement of load for each of the plurality of AP devices, and associating a station (STA) device with the selected AP device, wherein the selected AP device and the STA device are capable of communicating data within a wireless local area network. Also, at least one measurement of signal strength as measured at the STA device for each of the plurality of AP devices may be obtained, and automatic selection of one of the plurality of AP devices may further take into account the at least one measurement of signal strength for each AP device.

摘要： While setting up a fixed wireless system, each subscriber radiotelephone is configured to a permanent home cell. Subscribers located at the border of a cell may be configured to multiple cells for better coverage. The signal levels at the border subscriber's position are received and the mean values of each determined. These mean values are listed in descending order. If the largest mean value is greater than a predetermined threshold, the subscriber is configured to only the home cell. If the largest mean value is within a predetermined range, the second largest mean value is evaluated to determine if it is within the predetermined range. If so, the subscriber is configured to both serving cells. If the second largest mean value is outside the predetermined range, the subscriber is configured to only the home cell.

摘要： A fixed wireless access system includes circuitry for routing a call for a subscriber having a directory number not only through the primary cell, but also through any secondary cell for a border cell subscriber. In each case, the primary and secondary cells borders a geographically located near the geographic location of the border cell subscriber. For calls that are being routed to the border cell subscriber, one of a plurality of subscriber features including call forward no-answer, call forward unconditional or multiple access directory numbers may be used to cause the switch to trigger one or more fixed wireless access controllers to generate page request signals to the base stations for the border cell subscriber. For calls originated by the border cell subscriber, the subscriber's directory number is placed within the subscriber list for each base station whose cell borders are located geographically near the border cell subscribers geographic location. Accordingly, if the border cell subscriber unit locks onto a base station of a secondary border cell, the controller recognizes the subscriber unit and may process the call.
摘要翻译：固定的无线接入系统包括用于为具有不仅通过主小区的目录号码的用户路由呼叫的电路，而且还通过用于边界小区用户的任何二次小区路由呼叫。在每种情况下，主单元和次单元在边界小区用户的地理位置附近位于地理位置。对于被路由到边界小区用户的呼叫，可以使用多个用户特征中的一个，包括呼叫转移无应答，无呼叫前转无条件或多个接入号码，以使交换机触发一个或多个固定无线接入控制器以向边界小区用户的基站生成寻呼请求信号。对于由边界小区用户发起的呼叫，对于其小区边界位于边界小区用户地理位置附近的每个基站，订户的目录号码被放置在用户列表内。因此，如果边界小区用户单元锁定到辅助边界小区的基站，则控制器识别用户单元并且可以处理该呼叫。
