1. A measurement method, comprising:
determining, by a communications device, a first reference signal received power based on at least one reference signal received power measurement result on a first non-anchor carrier, including:
determining, by the communications device based on m reference signal received power measurement results on the first non-anchor carrier, m reference signal received power measurement results on a first anchor carrier, wherein the first anchor carrier is an anchor carrier of a serving cell, and m is a positive integer;
determining, by the communications device, the first reference signal received power based on M−m reference signal received power measurement results on the first anchor carrier and the m reference signal received power measurement results on the first anchor carrier, wherein the first reference signal received power is a reference signal received power on the first anchor carrier, M is greater than or equal to 2, and M is greater than m;
wherein the first non-anchor carrier is a carrier on which the communications device receives a paging message from a network device in the serving cell in which the communications device is located;
determining, by the communications device, a criterion S on the serving cell based on the first reference signal received power; and
wherein the criterion S is a basic condition for a terminal device to camp on a current cell, and the criterion S is met based on Srxlev>0 and Squal>0, wherein the Srxlev is a calculated cell received level value, and the Squal is a calculated cell quality value, both of the Srxlev and the Squal are used to determine whether the serving cell meets the criterion S.
