Claim 9:
10. A communications apparatus, comprising:
a transmitter;
a receiver;
a processor; and
a non-transitory computer readable medium having a program stored thereon for execution by the processor, the program including instructions to:
cause the transmitter to send a random access request to a network device, wherein the random access request comprises a random access preamble and uplink data;
receive, through the receiver, a random access response sent by the network device; and
perform a state transition AND/OR operation corresponding to a message format of the random access response that is a message format from a plurality of message formats comprising a first message format, a second message format and a third message format, wherein each message format of the plurality of message formats is different from each other message format;

wherein performing the state transition AND/OR operation comprises performing:
switching to a connected state in response to the random access response being in a first message format;
sending a radio resource control (RRC) connection request to the network device in response to the random access response being in a second message format; and
