Abstract
A random access method is described that includes a network device determines a first channel access type used by a terminal device to access a first unlicensed frequency band, where the first channel access type is one of channel access types of an unlicensed frequency band, and there are two channel access types of the unlicensed frequency band: frame based equipment (FBE) and load based equipment (LBE). The network device sends a first system message to the terminal device, where the first system message carries first indication information, and the first indication information is used to indicate the first channel access type. The terminal device obtains the first system message from the network device, and accesses the first unlicensed frequency band by using the first channel access type indicated by the first indication information.
