The present disclosure relates to communication methods and apparatus. On one example method, a terminal device obtains measurement results of N cells, where the N cells include M non-public network cells, where N is an integer greater than or equal to 1, and where M is an integer greater than or equal to 0. The terminal device determines, based on the measurement results of the N cells and measurement result offset values corresponding to H first cells in the N cells, a target cell on which the terminal device is to camp, where H is an integer greater than or equal to 1, and where H≤N.
