Claim 13:
14. A communications apparatus, comprising:
a receiver;
a transmitter;
a processor; and
a non-transitory computer readable medium having a program stored thereon for execution by the processor, the program including instructions to:
receive, though the receiver, a random access request sent by a terminal device, wherein the random access request comprises a random access preamble and uplink data, and wherein the terminal device is in an inactive state; and
cause the transmitter to send a random access response to the terminal device, wherein the random access response has a message format that is selected from a plurality of message formats comprising at least three message formats, wherein the at least three message formats comprises a first message format, a second message format and a third message format, wherein each message format of the at least three message formats is different from each other message format;
wherein the random access response being in the first message format triggers the terminal device to switch to a connected state;
wherein the random access response being in the second message format triggers the terminal device to send a radio resource control (RRC) connection request to the communications apparatus; and
