A camped cell determining method, executed by a user equipment, UE, the method comprising: determining, by the UE, whether the UE needs to reselect a cell based on a cell reselection criterion which includes a criterion H and a criterion R; if the UE does not need to reselect the cell, obtaining, by the UE, parameter information of a camped cell and parameter information of at least one non-camped cell, wherein the parameter information is reference signal received power, RSRP, or reference signal received quality, RSRQ; determining, by the UE according to the parameter information of the camped cell and parameter information of any non-camped cell, whether a preset condition is met; if the preset condition is met, sending, by the UE, an indication message to a network device, wherein the indication message is used to indicate that the camped cell is a poor camped cell, or the indication message is used to indicate a quantity of times that the camped cell is a poor camped cell during a time, whereby the network device performs radio frequency, RF, optimization on the camped cell or optimizes a reselection parameter of the camped cell; and camping, by the UE, on the camped cell, which is optimized, wherein the preset condition is used to ensure that the parameter information of the non-camped cell is greater than the parameter information of the camped cell; wherein the preset condition comprises: the parameter information of the camped cell is less than a first threshold, and the parameter information of the non-camped cell is greater than a second threshold; and/or a difference between the parameter information of the non-camped cell and the parameter information of the camped cell is greater than a third threshold; wherein the camped cell is a poor camped cell provided that the UE does not meet a reselection criterion but meets the preset condition; wherein the RF optimization includes adjusting an antenna delivery power, an azimuth or a down-tilt of the camped cell. determining, by the UE, whether the UE needs to reselect a cell based on a cell reselection criterion which includes a criterion H and a criterion R; if the UE does not need to reselect the cell, obtaining, by the UE, parameter information of a camped cell and parameter information of at least one non-camped cell, wherein the parameter information is reference signal received power, RSRP, or reference signal received quality, RSRQ; determining, by the UE according to the parameter information of the camped cell and parameter information of any non-camped cell, whether a preset condition is met; if the preset condition is met, sending, by the UE, an indication message to a network device, wherein the indication message is used to indicate that the camped cell is a poor camped cell, or the indication message is used to indicate a quantity of times that the camped cell is a poor camped cell during a time, whereby the network device performs radio frequency, RF, optimization on the camped cell or optimizes a reselection parameter of the camped cell; and camping, by the UE, on the camped cell, which is optimized, wherein the preset condition is used to ensure that the parameter information of the non-camped cell is greater than the parameter information of the camped cell; wherein the preset condition comprises: the parameter information of the camped cell is less than a first threshold, and the parameter information of the non-camped cell is greater than a second threshold; and/or a difference between the parameter information of the non-camped cell and the parameter information of the camped cell is greater than a third threshold; wherein the camped cell is a poor camped cell provided that the UE does not meet a reselection criterion but meets the preset condition; wherein the RF optimization includes adjusting an antenna delivery power, an azimuth or a down-tilt of the camped cell.
