Patent ID: 8682310

Claim:
A network-based method of improving communications in a cellular wireless communication network wherein a first serving node including a first transceiver provides communication services to users in a cell covering a geographic area, comprising, by the serving node: monitoring user activity and determining the cell has deficient capacity if a traffic load exceeds a predetermined load threshold; monitoring user link quality metrics for users in the cell and determining the cell has deficient coverage if a link quality metrics for a predetermined number of users fall below a predetermined quality threshold; determining a geographic position of one or more users in the cell; and in response to detecting a pattern of capacity or coverage deficiency in the cell: performing measurements selected from the group consisting of Timing Advance (TAdv), Angle of Arrival (AOA), and neighboring nodes signal strength on the users indicating capacity or coverage deficiency; determining, in response to the measurements, that the deficiency is localized in an area of the cell; and determining that a second serving node should be deployed within the localized area to alleviate the deficiency; wherein the second serving node transmits at lower power level than the first serving node.
