A method for predetermining a resource in a process of random access, wherein the method comprises: receiving a random access preamble sent by user equipment, and determining preamble information according to the received random access preamble, wherein the preamble information comprises one or more of the following: the random access preamble, a random access preamble index, an index of a time resource used for transmitting the random access preamble, an index of a frequency resource used for transmitting the random access preamble, a start time resource in the time resource used for transmitting the random access preamble, and a start frequency resource used for transmitting the random access preamble; determining an RAR resource corresponding to the random access preamble according to a correspondence between the preamble information and random access response RAR resource information, wherein the RAR resource information comprises one or more of the following: the RAR resource, an RAR resource index, an index of a time resource used for transmitting an RAR message, an index of a frequency resource used for transmitting the RAR message, a start time resource in the time resource used for transmitting the RAR message, and a start frequency resource used for transmitting the RAR message, and the correspondence between the preamble information and the RAR resource information is configured by using signaling or preset by a system; and sending the RAR message corresponding to the random access preamble to the user equipment on the RAR resource corresponding to the random access preamble, wherein the correspondence between the preamble information and the RAR resource information is configured by using signaling or preset by the system, wherein the signaling comprises broadcast or multicast signaling, and the correspondence, configured by using signaling or preset by the system, between the preamble information and the RAR resource information is characterised by comprising: the RAR resource index corresponding to the random access preamble = the random access preamble index mod a quantity of RAR resources configured by using signaling or preset by the system, wherein herein mod denotes a modulo operation. receiving a random access preamble sent by user equipment, and determining preamble information according to the received random access preamble, wherein the preamble information comprises one or more of the following: the random access preamble, a random access preamble index, an index of a time resource used for transmitting the random access preamble, an index of a frequency resource used for transmitting the random access preamble, a start time resource in the time resource used for transmitting the random access preamble, and a start frequency resource used for transmitting the random access preamble; determining an RAR resource corresponding to the random access preamble according to a correspondence between the preamble information and random access response RAR resource information, wherein the RAR resource information comprises one or more of the following: the RAR resource, an RAR resource index, an index of a time resource used for transmitting an RAR message, an index of a frequency resource used for transmitting the RAR message, a start time resource in the time resource used for transmitting the RAR message, and a start frequency resource used for transmitting the RAR message, and the correspondence between the preamble information and the RAR resource information is configured by using signaling or preset by a system; and sending the RAR message corresponding to the random access preamble to the user equipment on the RAR resource corresponding to the random access preamble, wherein the correspondence between the preamble information and the RAR resource information is configured by using signaling or preset by the system, wherein the signaling comprises broadcast or multicast signaling, and the correspondence, configured by using signaling or preset by the system, between the preamble information and the RAR resource information is characterised by comprising: the RAR resource index corresponding to the random access preamble = the random access preamble index mod a quantity of RAR resources configured by using signaling or preset by the system, wherein herein mod denotes a modulo operation.
