2.2.5 Easy Operation and Maintenance
Through interworking with the management systems (LSM, Web-EMT, and CLI), the eNB
provides the maintenance functions such as system initialization and restart, system
configuration management, management of fault/status/diagnosis for system resources and
services, management of statistics on system resources and various performance data and
security management for system access and operation.
Graphics and Text Based Console Interfaces
The LSM manages all eNBs in the network using the Database Management System
(DBMS). The eNB also interworks with the console terminal to allow the operator to
connect directly to the Network Element (NE), rather than through the LSM, and perform
the operations and maintenance.
The operator can use the graphics-based console interface (Web-EMT, Web-based Element
Maintenance Terminal) or the text-based Command Line Interface (CLI) according to user
convenience and work purposes. The operator can access the console interfaces without
additional software. For the Web-EMT, the operator can log in to the system using Internet
Explorer. For the CLI, the operator can log in to the system using the telnet or the Secure
Shell (SSH) in the command window.
The operator can perform the management of configuration and operational information,
management of fault and status, and monitoring of statistics and so on. To grow/degrow
resources or configure a neighbor list that contains relation of multiple NEs, the operator
needs to use the LSM.
Operator Authentication Function
The eNB provides the authentication and privilege management functions for the system
operators.
The operator accesses the eNB using the operator’s account and password via the CLI.
At this time, the eNB grants the operator an operation privilege in accordance with the
operator’s level.
The eNB also logs the access successes and failures for CLI, login history, and so on.
Highly-Secured Maintenance
The eNB supports the Simple Network Management Protocol (SNMP) and SSH File
Transfer Protocol (SFTP) for security during communications with the LSM, and the
Hypertext Transfer Protocol over SSL (HTTPs) and Secure Shell (SSH) during
communications with the console terminal.
Online Software Upgrade
When a software package is upgraded, the EPC can upgrade the existing package while it is
still running.
The package upgrade is done by downloading a new package  activating of the new
package.
