Patent number: 11523316Abstract: Distribution of traffic to cells in a communication network can be controlled. A distribution management component (DMC) can determine overall device traffic throughput for cells of a sector that satisfy a defined traffic throughput criterion relating to a harmonic mean of the device traffic throughput for the cells to desirably enhance or maximize the harmonic mean of the overall device traffic throughput. Based on the overall device traffic throughput for the cells, the DMC can determine whether to adjust a characteristic associated with a cell of the cells to facilitate adjusting distribution of device traffic among the cells of the sector to achieve desirable load balancing of traffic by the sector and in the network. Load balancing can be achieved by controlling respective parameters with regard to communication devices that are in idle mode or connected mode to facilitate directing communication devices and associated traffic to desired cells.Type: GrantFiled: May 25, 2021Date of Patent: December 6, 2022Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Huahui Wang, Tae Won Cho, Gopalakrishnan Meempat, Henry Kafka, Ravi Raina, Xiaoyu Wang, Laurie Bigler
