According to a sixth embodiment of the present invention, this embodiment is based on the above embodiment, and introduces a present invention. Ming application examples.

The flow involved in the antenna fault determination method of this embodiment is as follows:

Step 1: Filter the antenna pairs corresponding to the cells covered by the base station based on the number of antenna balances and the RSSI data.

Among them, one or more of the following filtering methods can be used:

1) filtering the antenna pair corresponding to the cell covered by the base station having the "room" or "indoor" attribute;

2) In the antenna balance number, if an antenna is centered, one antenna balance number is 0, the other is not 0, or both antennas are 0, then the antenna pair of the cell is filtered out, and does not participate in subsequent Calculation

In an optional technical solution, a count threshold, that is, a cell antenna balance threshold, may be added in the antenna balance number. The default value is 10000, and other values may be set as needed. The antenna pair of this cell is subsequently calculated only when the cell antenna balance statistics exceeds the threshold in one of the pair of antennas.

3) In the RSSI data of one week, if the RSSI maximum value of one of the pair of antennas is ≥ 0, the antenna pair is filtered out and does not participate in subsequent calculations.

Step 2: For all antenna pairs remaining after filtering, in order to ensure the uniqueness of the calculated antenna pair, the following cyclic calculation is performed one by one by using "radio network controller ID + base station ID + cell ID + antenna pair ID" as an index:

A1: In the number of antenna balances, firstly collect the sum of the antenna balance times of the two antennas in each antenna pair in one week, and then calculate the balance number of the antenna pair by dividing the sum of the larger values by the sum of the smaller values. The ratio is recorded as the antenna main diversity balance.

A2: If the antenna primary diversity balance is ≥ 3, the calculation of step A3 is performed, and if it is less than 3, the jump is performed, and the calculation of the next antenna pair is performed.

A3: using the "radio network controller ID + base station ID + cell ID + antenna pair ID" as an index, find the RSSI data of the two antennas in the antenna pair in the RSSI data recorded in the week, and take the larger one as The maximum diversity of the primary diversity RSSI of the antenna pair. If the maximum value of the primary diversity RSSI is less than -103 dBm, it is determined that the antenna pair is not connected to the antenna diversity, and the output suggests "antenna failure. Please check whether the diversity antenna is connected. Perform the calculation of the next antenna pair. If it is not less than -103dBm, subtract the corresponding RSSI data of the two antennas of the antenna pair and take the absolute value to obtain the maximum RSSI of the antenna main diversity. The difference is then averaged relative to the number of RSSI record points in a week to obtain an average of the RSSI maximum difference of the antenna main diversity.

A4: If the average value of the 0.25 ≤ antenna main diversity balance/antenna main diversity RSSI maximum difference of the antenna pair is ≤ 4, it is determined that the antenna pair is reversed or inverted, and added to the size 鸳鸯In the reversed cell list, the calculation of the next antenna pair is performed. If the average value of the antenna main diversity balance/antenna main diversity RSSI maximum difference is not within the above numerical interval, the calculation of the next pair of antennas is directly performed.

Step 3: Determine an antenna fault related to the standing wave ratio for the antenna pair that has been determined to be reversed or inverted, and locate the cell in which the connection sequence error occurs.

Optionally, for any cell that has an inverted antenna pair, if there is no opposite antenna ID of the other cell in the same station, it is determined that “the antenna failure caused by the antenna standing wave ratio is too high”, Among them, the method of judging the same station: the same is the radio network controller ID + base station ID. The so-called co-located antenna ID means that if the cell is the antenna pair 1, 2, the other cell is also the antenna pair 1, 2.

If the same antenna pair in the same station has the same antenna pair, but the reversed antenna pair ID and the antenna pair ID under the cell are different, it is determined that the antenna is generated due to the antenna standing wave ratio being too high. malfunction";

If the cell (assuming CellID1) has another antenna pair of the same frequency cell (assumed to be CellID2) in the same station, the antenna pair is reversed, and the antenna pair ID and the presence of the CellID1 are connected. If the opposite antenna pair ID is the same, it is determined that "CellID1 and CellID2 antennas are reversed"; if the antenna pairs of the three intra-frequency cells of the station are reversed, and the antenna pairs of the three cells are reversed, If it is the same, it is determined that "CellID1, CellID2, and CellID3 have antenna reversal".

To determine the same-frequency cell in the same station, the wireless parameter table needs to be imported. When the two cells belong to the same radio network controller ID+base station ID, and the carrier center frequency DUARFCN used by the downlink channel is the same, the two cells are in the same station. Co-frequency cell. The above-mentioned inverse mean value is either a big reverse or a small reverse.
