1. A method for random access type selection, being applicable to a terminal device, the method comprising:
selecting a random access type according to target information, the target information comprising at least one of a round trip time (RTT) of signal propagation between the terminal device and a network device, a timing advance (TA) estimated by the terminal device, or a reference signal received power (RSRP) measured by the terminal device;
wherein selecting the random access type according to the target information comprises:
determining a first value according to both the RTT and the RSRP; and
selecting a contention-based 2-step random access when the first value is greater than a first threshold;
selecting a contention-based 4-step random access when the first value is less than or equal to the first threshold.
