1 Before You Start

1.5 Precautions for the Upgrade 

This document instructs operation personnel to upgrade co-MPT base stations in batches on the LMT.



Time mentioned in this guide is for reference only.



To guarantee that the base station can be correctly upgraded using the LMT, the web browser version of the PC on which the LMT is installed (LMT PC for short) must be: −Microsoft Internet Explorer 8 or 9 −FireFox 3.0 or later



If any of the following alarms is generated in the base station to be upgraded, clear the alarm before the upgrade. Otherwise, the upgrade will fail. −ALM-26235 RF Unit Maintenance Link Failure −ALM-25901 Remote Maintenance Link Failure −ALM-26270 Inter-System Communication Failure −ALM-26272 Inter-System RF Unit Parameter Settings Conflict −ALM-26274 Inter-System Board Object Configuration Conflict −ALM-26277 Inter-System Control Rights Conflict −ALM-26279 Inter-System Board Installation and Configuration Mismatch



Check whether the LMT IP address of the base station to be upgraded has been changed before the upgrade. If it has, obtain the new IP address.



Do not run configuration commands for the base station that is being upgraded, including the ADD, MOD, RMV, and SET commands. If you must do so, log in to the LMT and run the DSP SOFTSTATUS command to check the software status of the base station. Operations can be performed only when the software status is Idle.



If a license file needs to be reloaded for the target version, obtain the license file of the current version before the upgrade. Ensure that the original license file can be reloaded if the eNodeB is rolled back. Determine whether you need to apply for an eNodeB license and reload it by referring to section 3.9.1Checking Whether You Need to Apply for an eNodeB License. For details about how to back up a license file, see section 3.10Back Up the License File of an eNodeB.



This document uses the figures of the upgrade from BTS3900 V100R008C00SPC260 to BTS3900 V100R010C10SPC255 as an example. During the actual upgrade process, replace BTS3900 V100R010C10SPCXXX with BTS3900 V100R010C10SPC255.



Do not perform the following operations during the upgrade process, including software downloading, activation, and process between the downloading and activation:

5 Verifying the Upgrade

Verifying the Upgrade

After an upgrade, follow the instructions in this chapter to verify the upgrade.

If the base station cannot start up after the upgrade, it will be automatically rolled back to the source version. The rollback takes about 15 minutes, during which base station services and maintenance are interrupted. Therefore, wait 15 minutes before you log in to the base station using the LMT. After you successfully log in to the base station, perform a self-test on the LMT to check whether the rollback is successful. For details about how to perform a self-test, see 3.6Checking the Status of the Base Station.

5.1 Verification Checklist After the upgrade is complete, perform the tasks in Table 1.1 to verify whether the upgrade is successful. Table 1.1 Verification checklist No .

6 Rolling Back to the Source Version

Rolling Back to the Source Version

For a multimode base station, if multiple modes that have been upgraded to the target versions need to be rolled back, it is recommended that all the target versions be rolled back to the source versions. If configuration parameters are modified after an upgrade, this command will invalidate the modified values of the parameters. Before running this command, assess impacts of the modified configurations and determine whether the impacts are acceptable.

6.1 Manual Rollback 6.1.1 (Optional) Setting the Loading Control Rights Before the Rollback of the Multimode Base Station To set the loading control rights before the rollback of the multimode base station, perform the following steps: Step 1 Log in to the LMT. Step 2 Run the SET LOADCTRL command with the parameter settings shown iniFigure 2.1 in the MML window. Table 1.1 lists the parameter settings.

6.1.2 Rollback Process

During the rollback, do not reset the base station or any board, power off the base station, or remove any board. Doing so will cause the rollback to fail. Run the RBK SOFTWARE commandto perform a version rollback without the need of parameter settings. Then, the configuration data is restored to the pre-upgrade status. During the rollback, the MML command information pane shows the rollback progress. When the progress reaches 100% and the execution result is Operation Succeeded, the system is reset and the rollback is complete. If the execution result shows that Failed Boards is not 0, refer to section 7.3 "How to Back Up the License File of an eNodeB?" to resolve the problem.

If a license file is loaded during the upgrade, determine whether the license file needs to be reloaded based 3.9.1.1.1Step 1Table 1.1 after the version rollback from V100R010C10SPC255.

6.2 Verifying Services See 5Verifying the Upgrade.



After the software version is rolled back to a source version earlier than SRAN10.1, the names of new alarms and events in SRAN10.1 will be displayed as Undefined on the LMT.



After an eNodeB in V100R010C00SPC050 is rolled back to the source version that is earlier than V100R010 series, there is a low possibility that ALM-26200 Board Hardware Fault is reported on the LBBPc. If the alarm cannot be cleared within 10 minutes, run the RST BRD command to reset the LBBPc to resume services.

7.3 How Do I Determine the BootROM Version? Run the DSP BRDVER command to query the BootROM version of the board. The released BootROM versions are numbered in two formats: XX.XXX.XX.XXX and VXXXRXXXCXXBXXX. You can use either of the following method to determine which version is an earlier one: 

Versions with the format XX.XXX.XX.XXX are released later than those with the format VXXXRXXXCXXBXXX.



Eliminate the non-digital characters contained in the version number in the same format, and you get a number. The larger the number, the later the BootROM version is. For example: In Version A (01.012.00.200) and Version B (01.013.01.001), the number of Version A is 101200200 and the number of Version B is 101301001. Because 101301001 is larger than 101200200, Version B was released later than Version A.

7.4 How Do I Select and Use Upgrade Software Packages? Upgrade Software Packages From BTS3900 V100R008 onwards, there are two kinds of upgrade software packages: SRAN package and single-mode package.
