1. A cell reselection method, performed by a terminal, comprising:
receiving first priority information of a combination of a frequency point and a network slice supported by the frequency point; and
performing a cell reselection based on the first priority information at least in part by:
for a reselection of an intra-system inter-frequency cell, an intra-system intra-frequency cell and an inter-system cell, determining based on the first priority information whether a cell with a priority higher than or equal to a priority of a serving cell of the terminal exists in the intra-system inter-frequency cell, the intra-system intra-frequency cell and the inter-system cell; and
in response to inexistence of a cell with a priority higher than or equal to the priority of the serving cell of the terminal, when a signal quality of the serving cell is less than a second threshold and a cell with a signal quality higher than a third threshold exists in the intra-system inter-frequency cell, the intra-system intra-frequency cell and the inter-system cell, determining a cell with a signal quality higher than the third threshold as a target cell in the cell reselection.
