2Huawei Proprietary and Confidential



Table 1-1 Upgrade scenario

Upgrade Scenario

Description


In this scenario, the specifications related to the BTS software to be loaded and the BTS software to be activated are as follows:

A maximum of 500 BTSs can be loaded at a time, but you are advised to load 300 BTSs at a time. In addition, you are advised to load a maximum of 100 BTSs (in parallel mode) of one BSC at a time.

If the number of BTSs to be loaded on the BSC exceeds 100, every 100 BTSs increases the loading time at a step equal to the time it takes for 100 BTSs to be loaded.

The M2000 allows BTSs under a maximum of five BSCs to be activated at a time. A maximum of 500 BTSs can be activated at a time, but you are advised to activate 75 BTSs at a time. In addition, you are advised to activate a maximum of 15 BTSs of a BSC at a time.

In this scenario, the BSC is not reset. Therefore, the services of the BTSs that are not upgraded are not affected.

Large-sized BTS upgrade (resetting the BSC)

In this scenario, the specifications related to the BTS software to be loaded and the BTS software to be activated are as follows:

A maximum of 500 BTSs can be loaded at a time, but you are advised to load 300 BTSs at a time. In addition, you are advised to load a maximum of 100 BTSs (in parallel mode) of one BSC at a time.

If the number of BTSs to be loaded on the BSC exceeds 100, every 100 BTSs increases the loading time at a step equal to the time it takes for 100 BTSs to be loaded.

The M2000 allows BTSs under a maximum of five BSCs to be activated at a time. A maximum of 500 BTSs can be activated at a time, but you are advised to activate 300 BTSs at a time. In addition, you are advised to activate all the BTSs under a BSC to be activated.

The upgrade in this scenario is quick, but the BSC in this scenario is reset. Therefore, the services of all the BTSs under the BSC are interrupted.

The BTS can be upgraded to the target version on the M2000, SMT, or USB storage device. For details, see “1.1.1 Table 1-1Mapping between upgrade guide, upgrade mode, and upgrade scenario”;

1.4 Impacts of the Upgrade

Impacts on Services

During software activation, the services are interrupted. The interruption time depends on the upgrade scenario, as described in Table 1-1.

Table 1-1 Impacts of software activation on services

Upgrade Scenario Service Interruption Time

Small-sized BTS upgrade (without resetting the BSC) (15 BTSs) 9–20 minutes

Large-sized BTS upgrade (resetting the BSC) 9 minutes




During the small-scale BTS upgrade (from BTS3000V100R008 to BTS3000V100R009), the service interruption time depends on the number of upgraded BTSs and the types of configured boards in the BTSs. The service interruption time of a BTS is related to the upgrade sequence of the BTS in the upgrade task. For example, if 15 BTSs are upgraded and the BTS configuration is GTMU+DRFU, the services of the 15 BTSs are interrupted for 9 to 20 minutes.

The service interruption time of the cascaded BTSs changes in a certain range.

When the alarm indicating that the GSM cells are out of service is cleared, the services are resumed. In other words, the service interruption time ends when this alarm is cleared.

Impacts on Network Communications

During software activation, the communication between the BTS and the BSC is interrupted. The interruption time depends on the upgrade scenario, as described in Table 1-1.

Table 1-1 Impacts of software activation on communication

Upgrade Scenario Communication Interruption Time


2 minutes

Large-sized BTS upgrade (resetting the BSC) 7 minutes

1.5 Precautions1. Determine whether the M2000 and the BSC6900 should also be upgraded according to

the version configuration information released with the BTS3000V100R009C00SPC079 Release Notes.doc.

2. Services are interrupted during the upgrade. Therefore, the upgrade must be performed at the time specified by the customer.

3. The figures in this document are from iManagerM2000V200R009C00SPC250. This document takes the upgrade from BTS3000V100R008C11 to BTS3000V100R009C00SPC011 as an example.

4. The service interruption time and the communication interruption time mentioned earlier are obtained on the assumption that the network performance is the best. Therefore, the time is for reference only.

5. Configurations on the BSC6900 LMT or the CME require BTS configuration rights. Therefore, do not upgrade BTSs through the BSC6900 LMT or CME. Otherwise, the one-click upgrade may fail.

6. Before an upgrade from BTS3000V100R008 to BTS3000V100R009, data configurations must be converted according to the configuration model. Therefore, you need to confirm the configuration model of the upgraded BTS in advance. The configuration model refers to the relations between the CPRI connection and the physical location of the RFU or RRU. The configuration model may vary, depending on the type of BTS. If the required configuration model is not used in the commercial network, see section 7.6 "How toPerform the Software Upgrade If the Required Configuration Model Is Not Used in theCommercial Network?"






7. The BTSs whose versions are different before an upgrade should be upgraded in batches. For details, see section 7.5 "Why the BTSs of Different Versions Before the UpgradeCannot Be Upgraded in the Same Batch? Why the BTSs of Different Target VersionsAfter the Upgrade Cannot Be Rolled Back in the Same Batch?"

Table 3-1 Checklist of data collection in the case of software activation failure

Data Collection Operation

BSC logs On the BSC6900 LMT, run the LST OMUAREA command to query whether the active directory is version_a or version_b.

Log in to the BSC6900 file server. Save the configure.log file to the directory \mbsc\bam\version_a\log or \mbsc\bam\version_b\log.







BTS configuration data On the BSC6900 LMT, run the LST OMUAREA command to query whether the active directory is version_a or version_b.

Log in to the BSC6900 file server. Save all the files to the directory \mbsc\bam\version_a\ftp\bts_upgrade or \mbsc\bam\version_b\ftp\bts_upgrade.

CAUTION

If the pre-activation check on the configuration data is successful, do not perform data configuration on the BTS before an upgrade. If the check fails, check whether the pre-activation of the configuration data is successful.

The time for checking the pre-activation of the configuration data depends on the number of BTSs.

− The pre-activation check on every 50 BTSs takes about 20 minutes.

− The pre-activation checks on the data configuration of different BTSs controlled by a BSC are performed in serial mode. Therefore, the time for checking each set of 50 BTSs increases by 20 minutes. For example, the pre-activation check on 150 BTSs takes 60 minutes (20 minutes x 3).

Step 1 Log in to the M2000 client, and then choose Software > NE Upgrade Task Management > NE Upgrade Task. On the displayed Upgrade Task Management tab page, click Create in the upper left corner. Then, on the displayed menu, choose GBTS > GBTS Special Configuration & Software Upgrade (MBTS).

3.15 Loading the BTS SoftwareBefore loading the BTS software in the case of a small-scale or large-scale upgrade, see the system specifications, as shown in 1.2.1 Table 1-1.




CAUTIONIf the version of the BTS software is BTS3000V100R008C11 before an upgrade, do not reset the BTS after loading the BTS software and before activating the BTS software. If you reset the BTS at that time, you must re-load the BTS software.

The elapsed time for loading the BTS software depends on the number of upgraded BTSs and the types of configuration boards in the BTSs.

In the case of not more than 100 BTSs: Assume that the number of BTSs to be loaded is 100 and the BTS configuration is GTMU+DRFUs. In this case, the BTS software loading in ordinary mode takes 45 minutes, either in small-scale or large-scale upgrade.

In the case of more than 100 BTSs: Assume that the number of BTSs to be loaded is 150 and the board configuration is GTMU+DRFUs. In this case, the BTS software loading in ordinary mode is divided into two batches, either in small-scale or large-scale upgrade. The first batch loading completes 100 BTSs and the second batch loading completes the remaining 50 BTSs. The loading time is 90 minutes (45 minutes x 2 batches).

Step 1 Log in to M2000 client, and then choose Software > NE Upgrade Task Management > NE Upgrade Task.

Step 2 On the displayed Upgrade Task Management tab page, click Create in the upper left corner. Choose GBTS > GBTS Special Configuration & Software Upgrade (MBTS).

2 Loading the BTS Software




− Upgrade solution: Perform Small-sized BTS upgrade (without resetting the BSC) or Large-sized BTS upgrade (resetting the BSC). For details, see 7.4.1 Table 7-1.

− Configuration model: not required in the case of rollback− Operation selection: select Quick load and Load by

Configuration

The software loading in quick load mode in the case of rollback can accelerate the loading process. Note that the quick load mode may lead to service interruption. In addition, the software loading duration varies with the number of BTSs and the types of configuration boards in the BTSs

− In the case of less than 100 BTSs: Assume that the number of BTSs to be loaded is 50 and the board configuration is GTMU+DRFUs. In this case, the BTS software loading in quick load mode takes 12 minutes, either in small-scale or large-scale upgrade.

− In the case of more than 100 BTSs: Assume that the number of BTSs to be loaded is 150 and the board configuration is GTMU+DRFUs. In this case, the BTS software loading in quick mode is divided into two batches, either in small-scale or large-scale upgrade. The first batch loading completes 100 BTSs and the second batch loading completes the remaining 50 BTSs. Thus, the required duration of software loading is 12 minutes x 2 batches = 24 minutes, regardless of whether it is small-scale upgrade or large-scale upgrade.

7.4 How to Handle the BTS Software Upgrade Failure?

Answer:






The software upgrade failure may be caused due to various reasons. In this case, you need to perform the following operations:

Before collecting the information described in 7.3.1 Table 7-1, you must back up BTS configuration data.

Step 1 If the pre-activation check or activation of configuration data fails, contact Huawei engineers. See section 3.14 "Performing the Pre-activation Check on the Configuration Data" to ensure that the pre-activation check is successful.

Step 2 If the upgrade failure is caused by other reasons, collect the detailed information about the software upgrade failure. In addition to the information listed in 7.3.1 Table 7-1, you also need to collect the detailed information about the upgrade failure by double-clicking the progress field to open the Detail dialog box, which provides the detailed information about upgrade failure.

Before collecting the information described in 7.3.1 Table 7-1, you must back up BTS configuration data.

Step 3 After the related information is collected, you can perform re-upgrade or rollback according to the actual conditions.

Perform re-upgrade if the upgrade time permits.

− Conditions of re-upgrade

The re-upgrade function can be used only when the BTS software activation fails.

− Purpose of re-upgrade

If the software activation fails during the upgrade, the activation task needs to be recreated. On the BSC6900 LMT, however, the BTS of activation failure may not be displayed in the list. In this case, you can select Re-Upgrade to view all the BTSs controlled by the BSC, and then select the BTS of activation failure for re-activation.

− Re-upgrade solution

Re-upgrade can be performed only after a new task of Small-sized BTS upgrade (without resetting the BSC) is created. If re-upgrade fails, contact Huawei technical support engineers.

Perform rollback if the upgrade time does not permit.

− Conditions of rollback

Perform re-upgrade unless customers require rollback.

− Rollback solution

You are advised to perform small-sized BTS rollback. For details, see Table 7-1.






Table 7-1 Rollback scenario

Scenario Description

Small-sized BTS rollback If the small-sized BTS upgrade fails, perform the small-sized BTS rollback.

If the large-sized BTS (not more than 15) upgrade fails, you are advised to perform small-sized BTS rollback.

Large-sized BTS rollback If the large-sized BTS (more than 15) upgrade fails, you are advised to perform large-sized BTS rollback.

− Re-rollback is performed only when rollback fails. The usage of re-rollback is similar to the usage of re-upgrade.

− For details on version rollback, see chapter 6 "Version Rollback."

If the problem persists, contact the local Huawei office.

7.5 Why the BTSs of Different Versions Before the Upgrade Cannot Be Upgraded in the Same Batch? Why the BTSs of Different Target Versions After the Upgrade Cannot Be Rolled Back in the Same Batch?

Answer:

In the case of software upgrade, the BTS upgrade software package may be different (according to section 3.2 "Obtaining Reference Documents and the Target Software Package") for the BTSs of different versions before the upgrade. For a software upgrade, however, all the BTSs to be upgraded can only be loaded with the same upgrade software package. Therefore, the BTSs of different versions before the upgrade cannot be upgraded in the same batch.

You can load the BTS software in different batches based on the software packages and then activate the BTS software together.

In the case of software rollback, the rollback process is different for BTSs of different target versions. For example, the rollback process of the target BTS version BTS3000V100R008C02 is different from that of the target BTS version BTS3000V100R008C11. For details, see section 6.2 "Rollback Process."






7.6 How to Perform the Software Upgrade If the Required Configuration Model Is Not Used in the Commercial Network?

Answer:

If the required configuration model (for Turkey) for software upgrade is not listed in the current configuration model list (for general, for Czech Tmobile, and for Germany O2), you need to perform the following steps:

Step 1 Contact Huawei technical support to prepare the general file for Turkey model according to the actual network conditions. The name of the general file is SiteConvertDesc.xml. This file can be saved in any directory on the M2000 file server.

In this document, the general file is saved in the root directory of the FTP file server installed on the M2000.

Step 2 Log in to the M2000 client. Click on the tool bar. The MML Command window is displayed.

Step 3 On the left pane of the MML Command window, click BSC6900 GSM in NE Type. In the navigation tree, select a BSC version, as shown in Figure 7-1.

If the MML command configuration file of the current BSC version is not downloaded, a dialog box will be displayed prompting you to download the file from the server. Click YES, and the Upgrade dialog box is displayed. When the upgrade progress reaches 100%, the MML command configuration file is completely downloaded. Click OK.

Step 4 On the LMT interface of the MML Command window, enter DLD GENFILE in the

Command Input box. Click to set related parameters as follows:

Source File: .\SiteConvertDesc.xml






Destination File: \

IP Address: the IP address of the M2000 server

User Name: ftpuser by default

User Password of FTP SERVER: ftpuser by default

Step 5 Click .

Step 6 Check the progress report at the lower part of the MML Command window. Ensure that the general file is successfully downloaded.

Step 7 In the NE Upgrade Wizard dialog box, select the BSC whose general file is downloaded in Controller. The Turkey model is displayed in Configuration Model, as shown in Figure 7-1.

7.7 How to Enable and Disable the Automatic Loading and Activation Function in Batch Mode?

Answer:

Step 1 On the BSC6900 LMT, click Batch on the upper right corner of the window. The Batch tab page is displayed.

Step 2 Copy the required MML commands to be run in batch mode from the Example.txt file to the command input box. Select All, Step by Step, Breakpoint, or Range according to the actual situation, and then click Go, as shown in Figure 7-1. Messages are displayed, informing you of the execution result.






Because the loading and the activation of the software require the user to wait, thus you are advised to select the All mode. The execution modes and their meanings are as follows:

All: You only need to click Go once.

Step by Step: You need to click Go before each MML command is executed.

Breakpoint: You can set break points for the execution to control the execution process.

Range: You can specify the numbers of MML commands to be executed.
