Method for random access in idle state and device

A method for random access in an idle state, the method comprising:

• receiving, by an evolved NodeB (eNB), a random access preamble sent by user equipment (UE), and sending a random access response message to the UE according to the random access preamble, wherein the random access response message carries first uplink grant information;
• receiving, by the eNB, a first message sent by the UE according to the first uplink grant information, wherein the first message comprises R bits, and wherein the first message carries a buffer status report (BSR) and equipment priority information for indicating a scheduling priority of the UE, and the BSR is used to indicate a volume of to-be-sent data of the UE, and wherein the equipment priority information is carried in the R bits of the first message;
• and
• allocating, by the eNB, an uplink resource to the UE according to the BSR and the equipment priority information and sending second uplink grant information to the UE for indicating the uplink resource allocated to the UE by the eNB.

User equipment (UE), comprising:

• a sender, configured to send a random access preamble to an evolved NodeB (eNB);
• a receiver, configured to receive a random access response message sent by the eNB according to the random access preamble, wherein the random access response message carries first uplink grant information;
• a processor, configured to generate an equipment priority information for indicating a scheduling priority of the UE, and to send a first message to the eNB according to the first uplink grant information by using the sender, wherein the first message carries a buffer status report (BSR) for indicating a volume of to-be-sent data of the UE and the equipment priority information, and wherein the first message comprises R bits, and the equipment priority information are carried in the R bits;
• wherein the receiver is further configured to receive second uplink grant information sent by the eNB, wherein the second uplink grant information indicates uplink resource allocated to the UE by the eNB according to the BSR and the equipment priority information;
• and
• wherein the processor is further configured to send the to-be-sent data to the eNB according to the second uplink grant information by using the sender.

A base station, comprising:

• a receiver, configured to receive a random access preamble sent by user equipment (UE);
• a sender, configured to send a random access response message to the UE according to the random access preamble, wherein the random access response message carries first uplink grant information;
• wherein the receiver is further configured to receive a first message, comprising R bits, sent by the UE according to the first uplink grant information, wherein the first message carries a buffer status report (BSR) for indicating a volume of to-be-sent data of the UE and equipment priority information for indicating a scheduling priority of the UE, and wherein the equipment priority information is carried in the R bits;
• a processor, configured to schedule the UE, and allocate an uplink resource to the UE according to the BSR and the equipment priority information;
• and
• wherein the sender is further configured to send second uplink grant information to the UE for indicating the uplink resource allocated to the UE by the base station.
