1.3 Impact of the Upgrade

Impact on Services

During software activation, BTS services are interrupted for three minutes.

BTS services are interrupted during a BTS upgrade. The duration of the service interruption depends on the software loading mode. This section uses a BTS with the DRFU + GRFU + GTMU configuration as an example to show the duration of the service interruption in different modes during an upgrade, as listed in Table 1-1.

Table 1-1 Impacts of the upgrade on the ongoing system

Software Loading Mode

Duration of the Service Interruption during loading

Duration of the Service Interruption during activation

TDM transmission mode

IP transmission mode

TDM transmission mode


Normal Mode 0 minutes 0 minutes 3 minutes

Rapid Mode (No Service)

20 minutes 0 minutes 3 minutes

Rapid Mode (Reserve BCCH trx)

0 minutes 0 minutes 3 minutes

In IP transmission mode, services will not be interrupted during loading for three Load Modes. In TDM transmission mode, the values for Load Mode are described as follows:

Normal Mode: Software loading does not interrupt ongoing services.

Rapid Mode (No Service): Software loading interrupts services on all TRXs.

Rapid Mode (Reserve BCCH trx): Software loading interrupts services only on non-BCCH TRXs.

Impact on Network Communications

During software activation, the communication between the BTS and the BSC is interrupted for two minutes.

1.4 Precautions

1.4.1 Notes1. Determine whether the M2000 and BSC6900 need to be upgraded according to the

"Related Product Versions" section in the 3900 GSM Series Base Station V100R013C00SPC047 Release Note.




2. Services will be interrupted during the upgrade. Therefore, you are advised to upgrade the BTS software during off-peak hours.

3. During the BTS upgrade process, do not reset boards or the BTS.

4. The figures in this document are captured from iManagerM2000 V200R011C00SPC200. This document uses the upgrade from BTS3000V100R009C00 to BTS3000V100R013C00SPCXXX as an example.

5. The time information required for each procedure is for reference only.

6. Configurations on the BSC6900 LMT or configuration management express (CME) require BTS configuration control rights, which may result in a BTS upgrade failure on the M2000. Therefore, during the BTS upgrade on the M2000, do not use the BSC6900 LMT or CME to perform any operations on the BTSs to be upgraded.

7. Data configuration on the SMT will occupy BTS management rights, which may result in a BTS upgrade failure on the M2000. Therefore, during the BTS upgrade on the M2000, do not use the SMT to obtain BTS management rights on the BTSs to be upgraded.

8. The M2000 can upgrade software only for the following boards: GTMU, TRX board, UBRI and UTRP. The software of the monitoring boards and USCU must be upgraded on the BSC6900 LMT or SMT. For details, see the 3900 Series GSM BTS V100R013C00SPC047 Upgrade Guide (BSC6900 LMT-Based) and 3900 Series GSMBTS V100R013C00SPC047 Upgrade Guide (SMT-Based).

9. When upgrading a BTS on the iManager M2000 V200R010C00SPC200 or a later version, do not turn on or turn off the automatic loading and activation switch manually, because the M2000 automatically turns on and turns off the switch. Before performing a loading task, the M2000 disables the automatic loading and activation switch. After the loading task is complete, the Auto Download Active Function Switch is OFF. After the activation task is complete, the M2000 enables the automatic loading and activation switch.

10. If the BTS software does not run properly after the upgrade or KPIs after the upgrade do not meet the customers' requirements, perform version rollback and contact Huawei technical support.

11. Only BTS3000V100R012 or later versions support the UTRP.

V100R013, M2000-Based)

CAUTION All modes of a multi-mode base station and the base station controllers (if any) must be

managed by the same M2000, and the modes have been bound to each other on the M2000. For details about how to determine the mode of a base station, see section 7.5 "How Do I Judge Whether a Base Station Runs in Multi-Mode or Single-Mode?"

For a multi-mode base station, ensure that the versions of different modes are compatible with each other after the upgrade. If a multi-mode and co-module base station is upgraded mode by mode, the upgrade interval between two modes should not exceed one day.

1.4.2 Upgrade Precautions

Table 1-1 Alarm generated on a dual-mode base station during a mode-by-mode upgrade

Precautions Aspect

Description

Problem Description

In versions earlier than BTS3900 V100R004C00SPC130(GBTS:BTS3000V100R013C00SPC019), Input Voltage Alarm Upper Threshold is set to a small value, 57V, which leads to a false alarm. Therefore, in BTS3900 V100R004C00SPC130(GBTS:BTS3000V100R013C00SPC019), the value of this parameter is changed to 58V.

However, this change causes the alarm ALM-26271 Inter-System Monitoring Device Parameter Settings Conflict to be generated when the following conditions are met:

The EMU board is shared between two modes of the dual-mode base station.

The version of one mode is upgraded to BTS3900 V100R004C00SPC130 (GBTS:BTS3000V100R013C00SPC019)or a later version during a mode-by-mode upgrade.

Impact When the EMU board is shared between two modes, the preceding alarm is generated if the values of Input Voltage Alarm Upper Threshold are inconsistent between two modes.

After the versions of two modes are both upgraded to BTS3900 V100R004C00SPC130 (GBTS:BTS3000V100R013C00SPC019)or a later version, the preceding alarm is cleared because the values of Input Voltage Alarm Upper Threshold are consistent between the two modes.




Precautions Aspect

Description

Workaround 1. Before the upgrade, remove the EMU board from the mode not to be upgraded by running one of the following commands:

RMV BTSBRD: used for GSM

RMV EMU: used for UMTS or LTE

2. If the EMU board is not removed from the mode not to be upgraded before the upgrade, manually filter out the preceding alarm after the upgrade.

Probability 100%

1.5 Mode-by-Mode Upgrade of a Multi-Mode Base Station

This section provides details about upgrading one mode of a multi-mode base station. You can ignore this section if the base station to be upgraded is not a multi-mode base station.

1.5.1 Impacts on the Services of the Peer EndUpgrading the GSM mode of a GL/GU/GUL multi-mode base station will interrupt the services of other modes for less than 3 minutes.

1.5.2 Loading Control RightsThe USCU and the RF modules shared by all modes of a multi-mode base station can be upgraded with the mode that has loading control rights.

The M2000 sets loading control rights automatically. For details about which mode has loading control rights, see Appendix 1 Version Mapping Information. You can obtain this appendix from the multi-mode base station release notes in the document package delivered with the software version of the multi-mode base station.

If ALM-26277 Inter-System Control Rights Conflict is reported, run the SET BTSLOADCTRL command to set loading control rights. For details, see section "7.6 How Do I Grant or Cancel Loading Control Rights in GSM Mode?".

6 Version Rollback

If the network malfunctions after the upgrade or the KPIs after the upgrade do not meet the operator's requirements, roll back the version and report the event to Huawei.

For a multi-mode base station, if multiple modes that have been upgraded to the target versions need to be rolled back, roll back all the modes to the source versions.

On the M2000 client, click and select the NE, then run the DSP BTSSWRBKCAP command to check whether a fast version rollback can be implemented. If the result shows that there is a software version that can be rolled back, perform the steps described in section 6.1 "Performing a Fast Version Rollback." If there is no version that can be rolled back, perform the steps described in section 6.2 "One-Click Rollback."

If network reconfiguration is required after the upgrade is complete, contact Huawei for technical support before performing the version rollback.

V100R013 supports the integrity protection of BTS software function, but V100R009 and V100R012 do not support the integrity protection of BTS software function. When rolling V100R013 back to V100R009 or V100R012, ensure that the integrity protection of BTS software function is disabled. Otherwise, the rollback fails. Run the MML command SET BTSDIGSIGN to set the integrity protection of BTS software function.

Before performing fast version rollback, run the MML command LST CMCTRLSW to check whether configuration management control switch on the BSC is enabled. If the switch is enabled, fast version rollback will fail. Therefore, before fast version rollback, run the SET CMCTRLSW command to disable the configuration management control switch.

Fast version rollback is faster than one-click version rollback because loading software is not required during fast version rollback. To perform a fast version rollback, perform the following steps:

Step 1 Log in to M2000 client, and then choose Software > NE Upgrade Task Management > NE Upgrade Task. The NE Upgrade Task tab page is displayed.

Step 2 On the displayed NE Upgrade Task tab page, click Create in the upper left corner. On the displayed list, select GBTS.

Step 3 In the displayed GBTS-NE Upgrade Wizard dialog box, set the rollback parameters, as shown in Figure 6-1.


2. Upgrade Type: select Rollback.

3. NEs to Be Selected: select NE(s) whose version is to be rolled back.

When rolling back the version of a single BTS, search the NE by entering the NE name. When rolling back the version of BTSs in batches, select BSC, Connection Status, NE Type, and Multi-mode to categorize the BTSs.

CAUTIONWhen rolling back upper-level and lower-level BTSs in cascaded mode on the M2000, if the upper-level BTS is rolled back and reset first, the communication between the lower-level BTS and the M2000 is interrupted. Therefore, the M2000 shows that the lower-level BTS fails to be rolled back due to timeout. The lower-level BTS, however, is actually rolled back successfully. To avoid this problem, it is recommended that you roll back cascaded BTSs one by one.

If the alarm is generated, wait five minutes for the alarm to clear. If the alarm clears, the BTS is rolled back successfully. If the alarm persists, the rollback fails.

If the progress does not reach 100% and a failure message is displayed, the rollback fails.




When fast version rollback fails, run the MML command LST CMCTRLSW to check whether the configuration management control switch on the BSC is turned on. If the switch is turned on, run the SET CMCTRLSW command to turn off the switch and then perform fast version rollback again. If the switch is turned off, contact Huawei technical support.
