  • Patent number: 11503484
    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 ?t, 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.
