Claim 5:
6. A network device, comprising: a memory, a processor, and a computer program that is stored in the memory and that can run on the processor, wherein the computer program, when executed by the processor, causes the processor to:
configure a first resource fora terminal device, wherein the first resource is used for 2-step random access, and the first resource is different from a resource of a normal random access procedure RACH; and
send a first message,
wherein the first message comprises:
a first part and a second part; and
the first part is used to indicate that the network device does not allow a terminal device without a 2-step random access function to be attached to the first resource, the second part is used to indicate that the network device allows a terminal device with a 2-step random access function to be attached to the first resource, and the first resource comprises a downlink bandwidth part used only for 2-step random access; or
the first part is used to indicate that the network device does not allow a terminal device without a 2-step random access function to initiate random access on the first resource or transmit data, the second part is used to indicate that the network device allows a terminal device with a 2-step random access function to be attached to the first resource or initiate data transmission, and the first resource comprises an uplink bandwidth part used only for 2-step random access;
wherein that the first resource is different from the resource of normal RACH comprises at least one of the following:
a random access preamble of the first resource is different from a random access preamble of the resource of the normal RACH; and
a location of the first resource is different from a location of the resource of the normal RACH.
