Abstract

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for informing identification of a UE (User Equipment) in the wireless communication system, the method comprising: receiving information related to a size of data to be transmitted to or from the UE, determining whether the UE is considered as the MTC_UE (Machine Type Communication _UE) or not based on the information; and informing a network that the UE is the MTC_UE by performing the MTC_UE specific access.

Claims

1. A method for a User Equipment (UE) operating in the wireless communication system, the method comprising:

receiving system information including a criterion value of a data size from a base station (BS), wherein the criterion value is to be compared with a size of a data available for transmission (DAT) of the UE;

determining whether the UE is considered as a Machine Type Commnucation_UE (MTC_UE) or not, by comparing the criterion value and the size of the DAT of the UE; and

performing a random access (RA) procedure, wherein the UE transmits a specific RA preamble dedicated for the MTC_UE only if the UE determines that the UE is considered as the MTC_UE, to the BS in the RA procedure.

2. The method of claim 1, further comprising:

receiving a paging message from the BS,

wherein the specific RA preamble is included in the paging message.

3. The method of claim 2,

wherein the paging message further includes a specific time value, and

wherein the UE determines that the UE is considered as the MTC_UE only during the specific time value if the size of the DAT of the UE is less than or equal to the criterion value.

4. The method of claim 1,

wherein the UE determines that the UE is considered as the MTC_UE if the size of the DAT of the UE is less than or equal to the criterion value.

5. The method of claim 4,

wherein the system information further includes a specific time value, and

wherein the UE determines that the UE is considered as the MTC_UE only during the specific time value if the size of the DAT of the UE is less than or equal to the criterion value.

6. The method of claim 1,

wherein the specific RA preamble is included in the system information.

7. A User Equipment (UE) for operating in the wireless communication system, the UE comprising:

an RF module; and

a processor to control the RF module,

wherein the processor configured to;

receive system information including a criterion value of a data size from a base station (BS), wherein the criterion value is to be compared with a size of a data available for transmission (DAT) of the UE;

determine whether the UE is considered as a Machine Type Commnucation_UE (MTC_UE) or not, by comparing the criterion value and the size of the DAT of the UE; and

perform a random access (RA) procedure, wherein the UE transmits a specific RA preamble dedicated for the MTC_UE only if the processor determines that the UE is considered as the MTC_UE, to the BS in the RA procedure.

8. The UE of claim 7, wherein the processor is further configured to receive a paging message from the BS,

wherein the specific RA preamble is included in the paging message.

9. The UE of claim 8,

wherein the paging message further includes a specific time value, and

wherein the processor determines that the UE is considered as the MTC_UE only during the specific time value if the size of the DAT of the UE is less than or equal to the criterion value.

10. The UE of claim 7,

wherein the UE determines that the UE is considered as the MTC_UE if the size of the DAT of the UE is less than or equal to the criterion value.

11. The UE of claim 10,

wherein the system information further includes a specific time value, and

wherein the processor determines that the UE is considered as the MTC_UE only during the specific time value if the size of the DAT of the UE is less than or equal to the criterion value.

12. The UE of claim 7,

wherein the specific RA preamble is included in the system information.
