1. A cell reselection method, applied to a terminal and comprising:
obtaining reselection information related to cell reselection, wherein the reselection information comprises a per-cell reselection parameter of a neighboring cell; and
performing a cell reselection procedure based on the per-cell reselection parameter and a reselection condition for reselecting to the neighboring cell;
wherein the per-cell reselection parameter comprises at least one of the following parameters:
a minimum received signal level parameter, wherein the minimum received signal level parameter comprises a per-frequency minimum received signal level value corresponding to the neighboring cell and a first offset value, wherein the first offset value is a difference between a target minimum received signal level value and the per-frequency minimum received signal level value;
a minimum received signal level offset parameter, wherein the minimum received signal level offset parameter comprises a per-frequency minimum received signal level offset value corresponding to the neighboring cell and a second offset value, wherein the second offset value is a difference between the target minimum received signal level offset value and the per-frequency minimum received signal level offset value;
a minimum signal quality parameter, wherein the minimum signal quality parameter comprises a per-frequency minimum signal quality value corresponding to the neighboring cell and a third offset value, wherein the third offset value is a difference between the target minimum signal quality value and the per-frequency minimum signal quality value;
a minimum signal quality offset parameter, wherein the minimum signal quality offset parameter comprises a per-frequency minimum signal quality offset value corresponding to the neighboring cell and a fourth offset value, wherein the fourth offset value is a difference between the target minimum signal quality offset value and the per-frequency minimum signal quality offset value;
a measurement offset parameter, wherein the measurement offset parameter comprises a per-frequency measurement offset value corresponding to the neighboring cell and a fifth offset value, wherein the fifth offset value is an offset between the target measurement offset value and the per-frequency measurement offset value;
a first target offset, wherein the first target offset is a sum of differences between per-cell parameter values and per-frequency parameter values of at least one of a minimum received signal level parameter, a minimum received signal level offset parameter, a power compensation parameter, or a measurement offset parameter;
a second target offset, wherein the second target offset is a sum of differences between per-cell parameter values and per-frequency parameter values of at least one of a minimum signal quality parameter, a minimum signal quality offset parameter, or a measurement offset parameter.
