Claim:
1. An accessing method, comprising: receiving, by a user equipment (UE), a synchronous channel resource set sent by a base station, wherein the synchronous channel resource set comprises information of at least one synchronous channel resource; selecting, by the UE, a first synchronous channel resource from the synchronous channel resource set; sending, by the UE, an access request to the base station using the first synchronous channel resource to request to access the base station; receiving, by the UE, access feedback from the base station; and determining, by the UE, whether access is successful according to the access feedback; wherein before sending the access request to the base station, the method further comprises: obtaining, by the UE, a timing advance rule and system information, and determining a timing advance value according to the timing advance rule and the system information, for performing uplink transmission according to the timing advance value, wherein the timing advance rule is used for indicating a corresponding relationship of the system information and the timing advance value.
