Abstract: A mobile station receives forward link signals and transmits reverse link signals for a communication session conducted via a wireless network. A controller maintains a reverse-active set that defines which sectors of the wireless network are used to receive the reverse link signals. When the mobile station transmits a request signal requesting the communication session, the controller may create the reverse-active set to include the sector that received the request signal with the highest signal strength. During the communication session, the signal strengths of the reverse link signals may be monitored in each of a plurality of sectors to obtain reverse-link signal strengths. The controller may maintain the reverse-active set based on the reverse-link signal strengths, adding sectors that report reverse-link signal strengths greater than an add threshold and dropping sectors that report reverse-link signal strengths less than a drop threshold.

Abstract translation: 移动站接收前向链路信号并发送用于通过无线网络进行的通信会话的反向链路信号。 控制器维护反向有效集合，其定义无线网络的哪些扇区用于接收反向链路信号。 当移动站发送请求通信会话的请求信号时，控制器可以创建反向有效集合以包括接收到具有最高信号强度的请求信号的扇区。 在通信会话期间，可以在多个扇区的每个扇区中监视反向链路信号的信号强度，以获得反向链路信号强度。 控制器可以基于反向链路信号强度维持反向有效集合，添加报告反向链路信号强度大于添加阈值的扇区，并且丢弃报告反向链路信号强度小于丢弃阈值的扇区。
