408 Automatic Loading and Activation of BTS TMU Version

Description

This alarm is generated when the BSC detects that the version of the existing TMU software is inconsistent with that of the configured TMU software and the BTS activates the configured TMU software.

Parameters

ID	Name	Meaning
1	Site No.	Number of the site where the TMU version is loaded and activated automatically.
2	Cause	1=Querying the current version number of the BTS failed,4=Activating the TMU version failed,5=Activating the TMU version succeeded,6=Get TMU software to download failed
3	NACK cause	14= Parameter value limit exceeded,19= Bts board not config,38= Target file does not exist,39= File cannot be activated,100= Bts version is same whit the running software version,145= No management rights,255=Null
4	Site Name	Site Name
5	Alarm Attribute	0=Normal, Alarms period are longer than the Transient Threshold. 1=Transient Count, The times and the period of the alarms whose periods are shorter than the Transient Threshold are summed up. If the sum result is longer than the Alarm Occurrence Period Threshold or Alarm Occurrence Times Threshold, an alarm so called Transient Count Alarm is triggered. Because Transient Count Alarm is based on accumulative result, the recovery of the alarm may occur at least one Summing Cycle later. The Summing Cycle can be query by MML "LST STATSLDWIN".

Impact on the System

If the value of Cause is 5, the configured TMU software is activated. During the activation, the BTS is re-initialized and the services are interrupted.
If the value of Cause is not 5, the configured TMU software is not activated, and the BTS is running on the existing version. The BTS is not re-initialized, and the services are not interrupted.

System Actions

None

Procedure

Check the Cause and the NACK cause in Location info.
1. If the value of Cause is 5, you can infer that the TMU software is successfully activated. Check whether the TMU software version is the same as the target version.
  Y => The alarm handling is complete.
  N => Reload the correct version of the TMU software. The alarm handling is complete.
2. If the value of Cause is 4 and that of NACK cause is 145, you can infer that there are conflicts in the BTS management rights. Go to 2.
3. If the value of Cause is 4 and that of NACK cause is 255, you can infer that the BTS is in abnormal state. Go to 3.
4. If the value of Cause is 1 or 4 and that of NACK cause is 255, you can infer that the BTS is in abnormal state or the Abis interface board of the BSC is faulty. Go to 3.
5. If the value of Cause is 1 or 4 and that of NACK cause is 14, you can infer that the transmission or communication between the BSC and the BTS is faulty.Go to 5
6. If the value of Cause is 6, you can infer that the BTS software version fails to be obtained from the OMU. Go to 7.
7. If the value of Cause is 1 or 4 and that of NACK cause is 38 or 39, you can infer that the TMUis faulty. Go to 8.
