Self-Configuration and Self-Establishment
Self-configuration and self-establishment enable automatic setup of radio
parameters and automatic configuration from system "power-on" to "in-service",
which minimizes the effort in installing the system. The detailed functions are as
follows.
 Self-Configuration (OTAR Based SON)
o Self-configuration of Initial Physical Cell Identity (PCI)
o Self-configuration of Initial neighbor information
o Self-configuration of Initial Root Sequence Index (RSI)
o Self-configuration of Initial Tx Power
o Self-configuration of Initial Carrier
 Self-Establishment
o Automatic IP address acquisition
o Auto OAM connectivity
o Automatic software and configuration data loading
o Automatic S1/X2 setup
o Self-test
Self-Optimization
PCI Auto-configuration
PCI Auto-configuration provides functions such as PCI collision/ confusion
detection and PCI reallocation.
Automatic Neighbor Relation
Automatic Neighbor Relation (ANR) configures and manages the intra-LTE NRT
to guarantee stable UE mobility in the LTE system. Samsung ANR fully meets the
requirements of the 3GPP LTE standard. Samsung ANR provides automatic NR
addition and X2 interface establishment function triggered by UE mobility and
periodical NRT management function.
Random Access Channel (RACH) Optimization
After PCI Auto-Configuration is done, RSI selection gets the selected PCI and
determines its index in the provisioned PCI list. RSI selection then chooses the
RSI with the same index in the provisioned RSI list, and informs to OAM and
stack.
Easy Operation and Maintenance
Through interworking with the management systems (SmallCell EMS and CLI),
the SmallCell provides the maintenance functions such as system initialization and
restart, system configuration management, management of fault/status/diagnosis
