CHAPTER 2. System Overview

1.0

The download and activation of a new package is performed using the Download menu and

Activation menu of the LSM GUI.

When upgrading the package, the service stops temporarily at the ‘change to the new

package’ step because the existing process needs to be stopped so that the new process can

start. Since the operating system does not need to be restarted, the service can be resumed

within several minutes. After upgrading the software, the eNB updates the package stored

in the internal nonvolatile storage.

Call Trace

The eNB supports the call trace function for a specific UE.

The operator can enable trace for a specific UE through the MME. The trace execution

results such as signaling messages are transmitted to the LSM.

OAM Traffic Throttling

The eNB provides the operator with the function for suppressing the OAM-related traffic

that can occur in the system using the operator command. At this time, the target OAM-

related traffic includes the fault trap messages for alarm reporting and the statistics files

generated periodically.

For the fault trap messages, the operator can suppress generation of alarms for the whole

system or some fault traps using the alarm inhibition command, consequently allowing the

operator to control the amount of alarm traffic that is generated. For the statistics files, the

operator can control the amount of statistics files by disabling the statistics collection

function for each statistics group using the statistics collection configuration command.
