The present disclosure provides a method for evaluating cross-cell coverage, which includes: finding, according to a neighboring cell configuration table of a cell in a base station, a cell with a number of configured neighboring cells that is larger than a number threshold for configured neighboring cells; designating the found cell as an original cell; carrying out a processing to obtain the cross-cell coverage evaluation parameters of the original cell; and determining the original cell i provides and/or suffers from cross-cell coverage when the cross-cell coverage evaluation parameter of the original cell exceeds respective cross-cell coverage evaluation thresholds. The present disclosure further provides an apparatus for evaluating cross-cell evaluation, which is capable of determining whether or not a cell provides cross-cell coverage to make parameters of a wireless network adjusted timely and limit the coverage of the wireless network in a supposed one.
