This application provides a PRACH resource selection method and an apparatus, to resolve a problem that a service requirement cannot be met in the prior art. In the method, a terminal device receives N synchronization signal blocks SSBs from an access device, determines a target PRACH resource selection manner based on at least one of a service type, a type of a trigger event that triggers random access, a signal strength change status of a reference signal received by the terminal device, mobility of the terminal device, and historical information, and selects, in the determined selection manner, a target PRACH resource from N PRACH resources corresponding to the N SSBs.
