1. An aggregate maximum bit rate (AMBR) control method, the method comprising:
obtaining, by a mobility management network element, M pieces of single network slice selection assistance information (S-NSSAI) corresponding to a terminal device and a first slice aggregate maximum bit rate (slice-AMBR) corresponding to each piece of S-NSSAI in the M pieces of S-NSSAI, wherein M is a positive integer, and wherein the first slice-AMBR corresponding to each piece of S-NSSAI is a subscribed first slice-AMBR corresponding to the S-NSSAI; and
sending, by the mobility management network element, the M pieces of S-NSSAI and the first slice-AMBR corresponding to each piece of S-NSSAI to an access network device, wherein the first slice-AMBR corresponding to each piece of S-NSSAI is used to determine at the access network device a second slice-AMBR corresponding to the S-NSSAI, and the second slice-AMBR corresponding to each piece of S-NSSAI is used to control an aggregate bit rate of non-guaranteed bit rate (non-GBR) quality of service (QOS) flows in a network slice indicated by the S-NSSAI.
