Abstract: Provided are a random access method, apparatus and system. The method includes: receiving, by a user equipment, configuration information of a Physical Random Access Channel (PRACH) dedicated for a super real-time service and/or configuration information of a preamble dedicated for the super real-time service notified by a base station; and when the user equipment has the super real-time service and has a short Transmission Time Interval (TTI) support capability, by the user equipment, transmitting a preamble to the base station through a PRACH resource dedicated for the super real-time service or transmitting the preamble dedicated for the super real-time service to the base station according to the configuration information of the PRACH dedicated for the super real-time service and/or the configuration information of the preamble dedicated for the super real-time service, so as to trigger the base station to allocate a short TTI resource to the user equipment.
