An OM command that queries the channel interference band level of a specified BTS. This command mainly queries the interference band level of idle channels to monitor the channel interference in real time.
The interference band level is the uplink interference level of a channel reported by the BTS to the BSC in the RF RESOURCE INDICATION message when the channel is idle. There are five levels of interference bands.
Each level range can be preset at the data configuration console:
Interference band 1: -105 dBm to -98 dBm;
Interference band 2: -98 dBm to -90 dBm;
Interference band 3: -90 dBm to -87 dBm;
Interference band 4: -87 dBm to -85 dBm;
Interference band 5: -85 dBm to -47 dBm
A high-level interference band indicates a high interference level.
Generally, if an idle channel falls in interference band level 4 or 5, the interference is counted.
1. The MML client should communicate with the BSC properly.
2. The BSC should communicate with the BTS properly.
| ID | Name | Description |
|---|---|---|
| IDXTYPE | Index type | Meaning: how to specify a BTS Value range: BYNAME(By Name), BYIDX(By Index) Explanation: This parameter determines whether to specify a BTS by its name or index. Default value: None |
| BTSIDX | BTS Index | Meaning: BTS index Value range: 0-2047 Explanation: 1. This parameter specifies the number of a BTS. Each BTS is numbered uniquely in a BSC. 2. This parameter is mandatory if Index Type is set to BYIDX(By Index). Default value: None |
| BTSNAME | BTS Name | Meaning: BTS name Value range: 1-32 characters Explanation: 1. This parameter specifies the name of the target BTS. Each BTS is named uniquely in a BSC. 2. This parameter is mandatory if Index Type is set to BYNAME(By Name). Default value: None |
| TRX | TRX No. | Meaning: TRX number Value range: 0-71 Explanation: 1. This parameter specifies the TRX number. 2. If this parameter is not specified, the channel interference band information of all the TRXs in the specified BTS are queried. Default value: None |
