Method and system for managing carrier frequencies in a wireless communication network
Abstract:
A method and system are provided for managing a radio access network (RAN). The RAN defines one or more wireless coverage areas (WCAs) to serve one or more mobile nodes (MNs). Each MN requests data from the RAN at a requested forward-link data rate and the RAN transmits data to the MN at an actual forward-link data rate.For each WCA, an average of the actual forward-link data rates, an average of the requested forward-link data rates, and an RF-link utilization is determined. The RF-link utilization of the WCA is determined by dividing the average actual forward-link data rate of the WCA by the average requested forward-link data rate of the WCA. The RAN is managed by scheduling the addition of one or more carrier frequencies to one or more WCAs, where the scheduling is based on the RF-link utilization of the WCAs.
Abstract(Chinese):

提供了一种用于管理无线电接入网络（RAN）的方法和系统。 RAN定义一个或多个无线覆盖区域（WCAs）以服务于一个或多个移动节点（MN）。 每个MN以所请求的前向链路数据速率从RAN请求数据，并且RAN以实际的前向链路数据速率向MN发送数据。 对于每个WCA，确定实际的前向链路数据速率的平均值，所请求的前向链路数据速率的平均值和RF链路利用率。 通过将WCA的平均实际前向链路数据速率除以WCA的平均所请求的前向链路数据速率来确定WCA的RF链路利用率。 通过调度对一个或多个WCA的一个或多个载波频率的添加来管理RAN，其中调度基于WCA的RF链路利用率。
