Abstract

Disclosed herein is a method of analyzing portable Internet signals in a measuring instrument. The method includes the steps of (a) acquiring synchronization using a preamble included in a currently received frame, (b) acquiring the access parameters of a DL_MAP included in the frame, and checking the validity of the DL_MAP, (c) if, as a result of the check at step (b), the DL_MAP is determined to be valid, acquiring downlink parameters and burst configuration information by interpreting the DL_MAP, and (e) performing a variety of diagnoses, including evaluation of signal quality for each burst, using the parameters and the burst configuration information.

Claims

1. A method of analyzing portable Internet signals in a measuring instrument, comprising the steps of:

(a) acquiring synchronization using a preamble included in a currently received frame;

(b) acquiring access parameters of a downlink_MAP (DL_MAP) included in the frame, and checking validity of the DL_MAP;

(c) if, as a result of the check at step (b), the DL_MAP is determined to be valid, acquiring downlink parameters and burst configuration information by interpreting the DL_MAP; and

(e) performing a variety of diagnoses, including evaluation of signal quality for each burst, using the parameters and the burst configuration information.

2. The method according to claim 1, further comprising, between steps (c) and step (e), step (d) of acquiring uplink parameters by analyzing an uplink_MAP (UL_MAP) included in the burst configuration information.

3. The method according to claim 2, wherein step (e) further comprises identifying the signal quality for each burst using a jog button.

4. The method according to claim 1, wherein the validity check at step (b) is performed using a Cyclic Redundancy Check (CRC) value included in the DL_MAP.

5. The method according to claim 4, wherein the access parameters of the DL_MAP comprise a length of a DL_MAP message and a repetitive encoding method of the DL_MAP message.

6. The method according to claim 5, wherein the variety of diagnoses at step (e) comprise Error Vector Magnitude, Error Vector Spectrum, Error Vector Time, I/Q Constellation, Cell ID, Segment, DL_MAP information, UL_MAP information, DL_MAP IE or UL_MAP IE.

7. The method according to claim 2, wherein the validity check at step (b) is performed using a Cyclic Redundancy Check (CRC) value included in the DL_MAP.

8. The method according to claim 3, wherein the validity check at step (b) is performed using a Cyclic Redundancy Check (CRC) value included in the DL_MAP.
