OMC Environment Setting
From the previous description of the differences in an SDR base
station and a traditional 2G base station, we know that the SDR
base station has two network management systems, that is, an
OMCR and an OMCB. Most of work is done on the OMCB, as
shown in Figure 1.13. In actual networking, we may install the
OMCB and the OMCR on two standalone servers, or integrate
them in one network management system (iSMG) and install them
on one server (SBCX). The installation and debugging in this
manual assume that the OMCB and the OMCR are installed on
one SBCX.

When an Abis Interface Uses E1/T1 as the Bearer
The Abis interface of the iBSC is connected to the base station by
means of an E1/T1 interface board (DTB) instead of an IPBB
interface board. It processes base station information on an EUIP.
In this case, the OMC-B operation and maintenance gateway of
the base station is the IP address set on the EUIP of the iBSC;
No Ethernet switch is used on the base station side. By means of
E1/T1, the base station is directly connected to the E1 interface
board (DTB) of the Abis interface of the iBSC

Networking description
When jointly deployed, an OMCB and an OMCR are logically two separate NM units
though they are physically installed on SBCX boards. In this case, the iBSC needs to
provide two IP interfaces, connected respectively to an SDR base station and an OMCB
server; the BSC needs to be configured with a virtual address (RPU interface address)

OMCB introduction
The configuration and management of conventional 2G BTS
(such as BTSV2 and BTSV3) is performed through OMCR
(including the iSMG). In contrast, the configuration of ZXSDR
BTS is mostly performed through LMT or OMCB (OMCR
completes the configuration of some wireless data only).
The Operation and Maintenance Center for Node B (OMCB) is
the operation and maintenance unit defined by 3GPP to
manage Node B. As dual-mode products supporting GSM and
3G systems, ZXSDR BTS also supports OMCB. The old single-
thread link mode (OMCRBSCBTS) is changed to the dual-
thread link mode (OMCBBTS and OMCRBSCBTS) and
then one more entity exists above BTS
OMCR data configuration
The OMCR data configuration mentioned in this
document refers to the ZXSDR-related data configuration
on the BSC side. The other configuration performed
during BSC installation commissioning is not described in
this document. The data configuration on OMCR covers
four parts:
a) Settings about BSC global resources;
b) Abis interface board configuration;
c) IP interface configuration;
d) Radio parameter configuration of ZXSDR sites.
OMCB data configuration
OMCB is the operation and maintenance center for
ZXSDR BTS. During the commissioning, you can
configure the data of ZXSDR BTS through OMCB. In
addition, the remote maintenance of ZXSDR BTS is also
implemented through OMCB.
LMT General introduction
LMT can be used to perform local debugging: Connect the
commissioning PC to ZXSDR and perform data configuration
locally through LMT software on the commissioning PC.
You can use LMT to configure
transmission-related data (such as IP addresses and routes)
physical configuration data (such as board configuration data
and topology relation data)
some radio configuration data (such as frequency band data
and central frequency data)
and to perform ZXSDR version management.
Synchronization
The synchronization between the foreground and the
background refers to the synchronization of data from the
foreground to the background or vice versa Three
conditions must be met before you can create a
connection between the foreground and the background:
The ZXSDR-related interface parameters have
been correctly configured on OMCR.
The ZXSDR management NE has been correctly
created on OMCB.
The transmission parameters have been correctly
configured on LMT.
SDR data configuration
It should be noted that the data configured on LMT is the same
as that configured on OMCB. During the commissioning of
ZXSDR, configure the data on the BSC side through OMCR
and then configure the data on the ZXSDR side. You may
configure the data on the SDR side in two ways:
a) configure all the data through OMCB, then configure the
transmission parameters of ZXSDR on LMT so that LMT
establishes a connection with the background, and finally
synchronizes the data from OMCB to ZXSDR;
b) configure all the data on LMT, then create the ZXSDR
management NE on OMCB so that the NE establishes a
connection with the foreground, and finally sends the
configuration data of ZXSDR to the background.
Configuration preparation
The configuration data to be prepared includes the BTS configuration data
and the Abis interface interconnection data. The BTS configuration data
includes the site type, the number of carriers per RRU, LAC, CI, and frequency
data. The Abis interface interconnection data includes the GSM site ID, the
BTS IP address, and the IP Abis address of iBSC

OMCR and OMCB
From the previous description of the differences in an
SDR base station and a traditional 2G base station, we
know that the SDR base station has two network
management systems, that is, an OMCR and an OMCB.
Most of work is done on the OMCB.In actual networking,
we may install the OMCB and the OMCR on two
standalone servers, or integrate them in one network
management system (iSMG) and install them on one
server (SBCX). The installation and debugging in this
manual assume that the OMCB and the OMCR are
installed on one SBCX.
When using IP over E1
By means of E1/T1, the base station is directly connected
to the E1 interface board (SDTB) of the Abis interface of
the iBSC;
The Abis interface of the iBSC processes base station
information on an EUIP. In this case, the OMC-B
operation and maintenance gateway of the base station is
the IP address set on the EUIP of the iBSC;
The OMC-B server is still accessed to the iBSC by means
of an IPBB board.
One example
The following table is an example of IP address planning. For the
sake of direct observation, the third digit of a base station IP
address is used to represent a site number, as shown by x in the
following table.

Networking description
When jointly deployed, an OMCB and an OMCR are logically two separate
NM units though they are physically installed on SBCX boards. In this case,
the iBSC needs to provide two IP interfaces, connected respectively to an
SDR base station and an OMCB server; the BSC needs to be configured
with a virtual address (RPU interface address).
Connection between the SDR and the BSC: When E1 is physically used for
access, the interface board on the SDR side is SA and that on the BSC side
is SDTB (EUIP is required for the access of IP); when FE/GE is used, the
interface board on the SDR side is CC and that on the BSC side is IPBB.
Connection between the OMCB and the BSC: when FE/GE is used, the
interface of the OMCB (that is, the external network interface of the SBCX)
is generally HEART1. IPBB is used on the BSC side.
Networking example
In the example as shown in above Figure, the IP address of the
OMCB server and that of the SDR are not in the same network
segment IP. Therefore, it is necessary to add a route from an
OMCB gateway to an SDR network segment.
How to Add route
In the Linux system, the command used to add a route is as follows:
route add -net destination network address gw next hop address netmask
network mask interface ip
In this example, the IP address of the OMCB server is 139.1.1.200. Its gateway
address, that is, the IPBB_OMCB address, is 139.1.1.254. The IP address of
the SDR is in the network segment 118.18.1.0. Then, the command used to
add a route to the iBSC virtual address on the OMCB (that is, the SBCX) is as
follows:
#route add –net 118.18.1.0 gw 139.1.1.254 netmask 255.255.255.0 eth1
Set a permanent route
After you have added a route by using the route add
command, to prevent the configured route being lost due
to the restart of the SBCX, you may edit the /etc/rc.d
/rc.local file as a root user and add the following line to
this file:
#route add –net 118.18.1.0 gw 139.1.1.254 netmask
255.255.255.0 eth1
Thus, each time the SBCX is started, the route will be
automatically added.
LMT General introduction
The software packet of the SDR often contains two files: one is the foreground software - software specification package, the other is the debugging software LMT.
General introduction
JRE installation
Load the JRE in running the LMT. If the JRE is not installed in the debugger, the JRE should be installed under the LMT directory. The path is \.....\BLMT_v4.00.101b2\JRE\jre-6u2-windows-i586-p.exe. (If a different LMT version and the JRE have been installed in the debugger, re-installation is not required.)
