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.)
