Automatic Software ManagementShort Term Requirements

Requirements Existing 3GPP Standards Status

“NE health-check”

OSS system has to be able to verify automatically that network elements are ready for software upgrade. The health-check (e.g. faulty HW Modules, critical alarms, free disk space) has to be executed during the dayshift to ensure the correct behavior and preconditions of the NE itself.

This is not explicitly mentioned in TS 32.53x, but could be easily introduced. Possible solutions could be an additional step/stop point and an extension / addition of a notification

Automated software download

The software download to the NEs should work in parallel with a minimum of unavoidable manual steps. A result overview list must be provided.

Supported by TS 32.53x Software Management IRP.

1. The profile configuration allows multiple network elements to download the software in parallel. For the network elements which meet the profile condition, they will initiate the software change accordingly.

2. The availability of new software in NE can be monitored by (5.5.6 Notification notifyNewSwAvailability (M)) (TS 32.532).

3. Manual operations (downLoadNESw, installNESw, ActivateNESw are also supported (TS 32.532).

Automatic Software ManagementShort Term Requirements


One-click NE software activation

Software activation should also work in parallel with a minimum of unavoidable manual steps. The NE health-check should support also the wrap-up activities for urgent issues.


1. The profile configuration allows multiple network elements to activate the software in parallel automatically.

2. The resumeSwMProcess operation can work for one-click NE software activation when a stop point has been configured in the profile.

3. Manual operations (downLoadNESw,installNESw,ActivateNESw can be used for urgent issues on individual NE (TS 32.532).

Automatic rollback

Only if the software activations fail completely an automatic rollback should be initiated.

1. No automatic rollback supported.

2. Manual operation (swFallback) has been designed for individual NE (TS 32.532).

Automatic Software ManagementLong Term Requirements


SW package is made available on OSS, and NEs are tagged on OMC for upgrade. Policies for software activation are set.


1. The profile configuration allows operators configured software management policies.

All necessary activities (NE-health check, SW download, SW activation, corrective actions) are carried out policy controlled by the software management application.


1. The profile configuration allows operators configured software management policies.

A final upgrade report is provided that will be used as basis for the final wrap up phase.


1. The availability of new software in NE can be monitored by (5.5.6 Notification notifyNewSwAvailability (M)) (TS 32.532).

Automatic Software ManagementLong Term Requirements


It is understood that with the long term approach the operator looses detailed control of each single step necessary for a software upgrade. A policy controlled bulk software upgrade is expected to be less error prone than today’s solutions

The policy management has been defined in TS 32.53x.
