A method of processing in random access procedure performed by a base station and a random access node, comprising the following steps: the random access node transmitting a Preamble to the base station; the base station calculating a timing alignment TA according to the Preamble detected by the base station itself and transmitting the TA to the random access node; the base station receiving random access detection information reported from a transparent relay station and selecting as a service node for the random access node one of the base station and the transparent relay station; the random access detection information including identification information of the received Preamble, the received power of the received Preamble and the TA corresponding to the received Preamble; the transparent relay station being a station that does not transmit downlink synchronous channel broadcast messages, system configuration broadcast messages or resources allocation broadcast message; the random access node adjusting an uplink timing advance according to the TA calculated by the base station and transmitting uplink signaling to the base station; the base station determining whether the random access node collides with other random access nodes according to the identification information transmitted by the random access node in said uplink signalling, and notifying the random access node of collision detection result through a contention resolution message and notifying the random access node of an access condition through the contention resolution message according to the selected service node, and the random access node performing an access procedure based on the access condition; wherein the step of notifying the random access node comprises, if the base station selects the base station as the service node for the random access node, the base station notifying the random access node of a collision detection result; if the base station selects the transparent relay station as the service node for the random access node, the base station transmitting the TA calculated by the transparent relay station and the collision detection result to the random access node through the contention resolution message. the random access node transmitting a Preamble to the base station; the base station calculating a timing alignment TA according to the Preamble detected by the base station itself and transmitting the TA to the random access node; the base station receiving random access detection information reported from a transparent relay station and selecting as a service node for the random access node one of the base station and the transparent relay station; the random access detection information including identification information of the received Preamble, the received power of the received Preamble and the TA corresponding to the received Preamble; the transparent relay station being a station that does not transmit downlink synchronous channel broadcast messages, system configuration broadcast messages or resources allocation broadcast message; the random access node adjusting an uplink timing advance according to the TA calculated by the base station and transmitting uplink signaling to the base station; the base station determining whether the random access node collides with other random access nodes according to the identification information transmitted by the random access node in said uplink signalling, and notifying the random access node of collision detection result through a contention resolution message and notifying the random access node of an access condition through the contention resolution message according to the selected service node, and the random access node performing an access procedure based on the access condition; wherein the step of notifying the random access node comprises, if the base station selects the base station as the service node for the random access node, the base station notifying the random access node of a collision detection result; if the base station selects the transparent relay station as the service node for the random access node, the base station transmitting the TA calculated by the transparent relay station and the collision detection result to the random access node through the contention resolution message.
