Abstract: A Physical Random Access Channel (PRACH) resource selection method includes a terminal device receiving N synchronization signal blocks (SSBs) from an access device, determining 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 selecting, in the determined selection manner, a target PRACH resource from N PRACH resources corresponding to the N SSBs.
