Abstract: This application provides a measurement method and apparatus, and relates to the field of communications technologies. The method includes: measuring a currently camped cell in Δt, to obtain {Si|i is a positive integer, i≤N}; if any Si in {Si|i is a positive integer, i≤N} satisfies that SREF−Si greater than or equal to a first threshold, updating SREF so that SREF is equal to SN; and measuring one or more neighboring cells of the currently camped cell if SREF−Si is greater than or equal to the first threshold. To be specific, when determining that a cell state variable in Δt is always less than a cell state reference variable, a terminal may start measurement on the neighboring cells, and update the cell state variable from SREF to a cell state variable SN obtained through the last measurement in Δt.
