1. A random access method, comprising:
receiving, by a terminal, random access configuration information from a network side device, wherein the random access configuration information comprises at least a random access threshold; and
selecting, by the terminal, a random access manner according to the random access configuration information;
wherein after the selecting, by the terminal, a random access manner according to the random access configuration information, the method further comprises:
using, by the terminal, the selected random access manner for nth random access, wherein n is a positive integer; and
after the nth random access fails or is not completed or is unsuccessful, selecting, by the terminal, a random access manner for (n+1)th random access according to any one of the following methods:
when both of the two random access manners can meet a preset priority requirement, selecting a random access manner different from that for the nth random access;
after the random access manner for the nth random access has been selected for a preset number of times, when both of the two random access manners can meet a preset priority requirement, selecting a random access manner different from that for the nth random access;
after the random access manner for the nth random access has been executed for a preset time, when both of the two random access manners can meet a preset priority requirement, selecting a random access manner different from that for the nth random access;
selecting a random access manner according to a newly generated random access parameter, wherein the newly generated random access parameter is less than a random access parameter corresponding to the nth random access, and a difference between the two random access parameters is a specified value; or
when both of the two random access manners can meet a preset priority requirement, selecting a random access manner according to the newly generated random access parameter, wherein the newly generated random access parameter is less than a random access parameter corresponding to the nth random access, and a difference between the two random access parameters is a specified value.
