摘要

A cell coverage management service associated with a wireless communication service provider may collect geolocated traffic data related to coverage areas of the provider's wireless communication network. The service may generate and update associations between geolocations and cells based on the traffic data and determine defects or deficiencies in the current coverage among cells. The service may further identify particular remedies or solutions to address the defects or deficiencies and implement the remedies at corresponding cell sites.

說明書

In situations where an area of high interference was identified, the cell coverage service 140 may determine downtilting the antenna(s) at overshooter cell(s) as a remedy. The angles for antenna downtilting may be calculated based on predetermined rule(s) or formula(e) involving the location, terrain, capacity, and signal strength of both the serving cell and overshooter cell(s). In situations where a poor coverage area was identified, the cell coverage service 140 may examine the distance, orientation, and signal strength of each cell that affects the poor coverage area and identify an intended serving cell. The cell coverage service 140 may then determine uptilting the antenna(s) at the intended serving cell as a remedy. The angles for antenna uptilting may be calculated based on predetermined rule(s) or formula(e) involving the location, terrain, capacity, and signal strength of the intended serving cell.

Because multiple cell coverage defects or deficiencies may be determined concurrently (or determined within a short period of time among one another) at block 406, remedies for the defects or deficiencies may involve inconsistent or contradictory actions at one or more cell sites. In these cases, the cell coverage management service 140 may prompt an engineer, operator, or administrator for prioritization or adjustment of certain remedies. In some embodiments, the remedy prioritization or adjustment may be automatically conducted based on predetermined remedy reconciliation rules.
