8.1 Overview

This chapter introduces cell-related basic operations. Including addition/deletion of a

cell, configuration of cell basic property data (such as cell system type, CGI, BTS

color code and network color code, cell installation status, cell available TRXs, and

TRX property, etc.), configuration of cell advanced property data, batch modification

of cell parameter etc.

8.2 Adding a Cell

Here, take "Module [3]" in the multi-module BSC as an example of adding a cell for

illustrating the configuration of cell data.

8.2.1 BTS Equipment

In the [Object List] window of the initial data configuration interface, click on the left

of "Module [3]". "Site0" configured under this module will be displayed, as shown inFigure 1.1

Figure 1.1 Select a site

Select "Site0" to pop up the [Site Device] tab page on the right interface, as shown in

The BTS type of "Site0" is BTS312. Six TRXs have already been configured to it. The

other boards are fully configured.

8.2.2 Adding a Cell

There are two methods to add a cell. Below, the characteristics and operation

procedures of the two methods are respectively described

I. Adding a Cell

the system will automatically name the new cell.

Start Cell No. None Start cell No. (cell ID). Cells are numbered

sequentially in a BM. If the cell numbers in a

specified range starting from the start cell No. have

already been used, new cells will be numbered

after the last occupied cell No. sequentially.

operation, this parameter is starting number used to

identify different cells.

If this parameter is selected, it indicates that the

new cell is to be named after the site.

II. Batch Adding Cells

This function is used to add a batch of cells to a BM by one operation. In system

deployment, or large-scale system expansion, this function can help the operator

save data configuration time.

Right click "Module [3]" in [object list], the short-cut menu will pop up, as shown in

this interface, FH modes can be selected, and MA groups and MAIO can be

automatically generated. The system supports cell baseband FH and RF FH.

The system will automatically search for the TRXs of the cell and list all of them in the

interface of FH Property. Select an FH mode among the three options "Not FH",

"Baseband FH" and "RF FH" in the pull-down list of [FH Mode], a dialogue box will

pop up for users to confirm the operation. See Figure 1.2.

Click , FH parameters can be configured.

II. Configuring Baseband FH

If "Baseband FH" is selected for FH mode, click in IFigure 1.2, the interface

shown in Figure 1.1 will pop up to query whether the baseband FH supports timeslot

FH.

FH Group No. None MA group No. MA is a frequency set composed of 64frequencies at the maximum. It is a sub-set of CA and

does not include BCCH frequencies under RF FH

mode. When the baseband FH supports timeslot FH,

at least two MA groups should be configured, one of

which does not include any BCCH frequency. If the

baseband FH supports timeslot FH for extension

BCCH, another group of MA is required to be

configured, not including the frequency for the

extension BCCH.

MAIO None It is recommended that the MAIO of each TS in a TRX

be the same and the MAIO of different TRXs in a cell

be different under frame FH. Under TS FH, the MAIO

of each channel in a TRX can be configured

differently.

Hopping None It is used to indicate whether each TRX is hopping.

When the baseband FH supports timeslot FH, at

Caution:

The HSN of all FH groups in the same cell must be the same.

Because RF FH is accomplished by changing the actual working frequency of the

TRX, the TRX properties under RF FH mode are different from those under other

mode. In Figure 1.1, double click any TRX in "TRX No.", [TRX Property] interface will

pop up, as shown in Figure 1.2.

Caution:

Under FH mode, TRXs cannot be deleted from the list of [Assigned Frequencies] in
