The receiving unit 101 of the wireless communication device 100 receives a MAC address and a service key from the mobile terminal 200 through wireless communication.

Here, the MAC address received from the mobile terminal 200 is a physical unique address of the wireless communication apparatus. The first half is a unique address of the manufacturer, and the second half is a unique address given arbitrarily by the manufacturer. For example, the MAC address may be a hexadecimal number with a MAC address size of 48 bits, such as "aa: bb: cc: dd: ee:

The MAC address received from the mobile terminal 200 may be a MAC address randomly changed for each connection between the mobile terminal 200 and the wireless communication device 100 in order to protect personal information of the mobile terminal user. For example, the MAC address received from the mobile terminal 200 in the initial connection may be "aa: bb: cc: dd: ee: ff" A randomly changed MAC address such as "dd: ee: cc: aa: ff: bb" may be received.

The service key received together with the MAC address may be assigned to each of the wireless communication device functions, and may be data having the same size as the MAC address.

If the encryption key received from the mobile terminal 200 matches the encryption key stored in the encryption key storage unit 104 and the mobile terminal 200 is authenticated, And extracts the service key from the cryptographic key received from the cryptographic module 200.

For example, if the encryption key received from the mobile terminal 200 and the encryption key stored in the encryption key storage unit 104 are "gg: dd: jj: hh: ii: ee: ff: kk: When the mobile terminal 200 is authenticated, the service key "gg: hh: ii: e: ff: kk: ll: aa: bb" : jj: kk: ll "can be extracted.

The division unit 110 of the wireless communication apparatus 100 grasps information on the communication environment between the wireless communication apparatus 100 and the mobile terminal 200 and divides the long data into a plurality of short data .

For example, as a result of acquiring information on the communication environment between the wireless communication apparatus 100 and the mobile terminal 200 through the division unit 110, data of a maximum of 1602 bytes can be transmitted through wireless communication, 200 is 16000 bytes, the dividing unit 110 sets 16000 bytes, which is the length of the transmittable data, to 1600 bytes excluding the length of the cyclic redundancy check data, which will be described later, to one data length of the short data . As a result, the long byte whose data length is 16000 bytes can be divided into 10 short data whose data length is 1600 bytes.

After the above-described header is transmitted to the mobile terminal 200, a plurality of short data may be sequentially transmitted to the mobile terminal 200 in accordance with the configuration order of the long data through the transmission unit 103 described above.

The cyclic redundancy checking unit 111 of the radio communication apparatus 100 checks whether transmission of each of a plurality of short data is completed through a cyclical redundancy check in the case where a plurality of short data is transmitted to the mobile terminal 200 The cyclic redundancy checker 114 may generate cyclic redundancy check data for each of a plurality of short data and merge the same at the end.

The communication control unit 113 of the wireless communication apparatus 100 receives the length information of the long data analyzed and analyzed from the header analyzing unit 112 and receives the short data from the mobile terminal 200 And controls the receiving unit 101.

For example, when the length information of the long data received from the mobile terminal 200 is analyzed to be 16000 bytes and provided to the communication controller 113, the communication controller 113 transmits a plurality of short data And when the length of the accumulated short data exceeds 16000 bytes, the receiving section 101 can be controlled to stop the reception of the short data.

Here, the cyclic redundancy check unit 111 of the radio communication apparatus 100 checks whether or not each of a plurality of short data has been received through a cyclical redundancy check when a plurality of short data is received from the mobile terminal 200 After the completion of the inspection, the cyclic redundancy checker 114 can remove the cyclic redundancy check data merged into each of the plurality of short data.
