8-2 Huawei Technologies Proprietary Issue 07 (2006-08-20)

8.1 Overview

This chapter introduces cell-related basic operations. Including adding/deleting a cell,

configuring cell basic property data (such as cell system type, CGI, BTS color code andnetwork color code, cell installation status, cell available TRXs, and TRX property, etc.),configuring cell advanced property data, batch modifying cell parameter etc.

8.2 Adding 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 Configuring BTS Equipment

Step 1 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 in Figure 8-1

Figure 8-1Select a site

Step 2 Select "Site0" to pop up the [Site Device] tab page on the right interface, as shown in Figure8-2

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

boards are fully configured.

8.2.2 The way to Add Cells

There are two ways to add cells. Below, the characteristics and operation procedures of thetwo ways are respectively described

Adding one Cell or multiple cells to a BM by one operation

Right click "Site0" of "Module [3]", the short-cut menu will pop up, as shown in Figure 8-3.

Start suffix No. None When multiple cells are to be added by one operation,

this parameter is starting number used to identifydifferent cells.

Cell Number None Number of the cells which are added to a site by oneoperation

Name cell bysite's name

Selected If this parameter is selected, it indicates that the new cellis to be named after the site.

in the User-defined template.

See Table 8-2 for the description of the parameters in [Batch Add Cells].

Table 8-2Description of the parameters in [Batch Add Cells]Parameter Default Description

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

sequentially in a BM. If the cell Numbers in aspecified range starting from the start cell No. havealready been used, new cells will be numbered afterthe last occupied cell No. sequentially.

MCC+MNC None MCC and MNC of the start cell.

LAC+CI None LAC and CI of the start cell.

CGI Increment Step 1 The increment step of CGI between two successivecells added in the batch addition procedure.

Modify Site No.Range

None This parameter is to specify the No. range of the sitesfor which cell batch addition is to be implemented.

Number of Cell in aBatch

None This parameter is to specify the number of cells to beadded for each site within the site No. range.

Add a Batch ofEmpty Sites

Selected New cells are only batch-added to the sites that havenot been configured with cells.

Use Default Cell

Template

Select Select this parameter to add a cell as defaulted. If not,

select user-defined cell template.

Each value in the panes of the interface is a frequency No., representing a frequency. Click the

pane where the value specified is located, and the color of the pane will become yellow,which means the frequency has been allocated to the cell. Click the pane again, the frequency

will be de-selected. Multiple frequencies can be selected or de-selected by using the right keyof the mouse to drag.

The frequencies include E-GSM and R-GSM frequencies, as shown in Figure 8-12.

8.3.8 Other Configurations

Configurations to sites and modules can be more easily done with short-cut menus.

Select and right click a module object, a short-cut menu shown in Figure 8-52 will pop up for

users to configure module properties and batch add cells.

Abis Flow Control

Permitted

Selected Whether to allow performing flow control for

Abis interface.

Allow Reassign selected Indicates whether to allow Reassign TCH.When BSC receive the ASSIGNMENT

FAILURE from UM, the BSC initiate thesecond ASSIGNMENT.

Frequency band of

reassign

Same band The parameter is used to choose band for

re-assignment.

If "Same Band" is selected, system will prefer

the channel in the same band forre-assignment; If "Different Band" is selected,

system will prefer the channel in the differentband for re-assignment.

Allow eMLPP Not

selected

Indicates whether to allow eMLPP. BSC

choose the lowest subscriber to handover, andthe higher subscriber obtains the idle TCH.

Idle TCH Thrsh. For SD

to TCH HO

80 When the idle rate of TCH reaches this threshold,

MS is allowed to directly hand over from SDCCHto TCH

Max. Radio CH ReleaseRetry Times

1 Indicates the maximum release retry times

allowed when the abnormal release of radiochannel occurs.

Service Type Req (SD

to TCH HO)

MSC

servicerequest

Indicates the allowed service request type when

the handover between SDCCHA and TCH occurs.Cannot be edited.

T3101(100ms) 30 Timer used in TCH immediate assignment. T3101

times when the TCH immediate assignment (IMMASS) is delivered and ends when the linkestablishment indication (EST IND) is reported. If

T3101 does not receive EST IND in the specifiedduration, BSS will release the SDCCH occupied.

T3103A(s) 10 In the case of intra-BSC handover, the timer startsat source cell delivering handover command to

MS, and stops at receiving internal clear

command or establish indication. In the case ofinter-BSC handover, the timer starts at source celldelivering handover command to MS, and stops at

receiving clear command or establish indicationfrom MSC.

T3103B1(s) 10 In the case of intra-BSC handover, the timer starts

at destination cell delivering internal handover

acknowledge, and stops at receiving handoverdetect or internal clear command. In the case ofinter-BSC handover, the timer starts at destination

cell delivering handover request acknowledge,and stops at receiving handover detect or clearcommand.

T3103B2(s) 10 The timer starts at destination cell receiving

handover detect (Not need to apply for an opticfiber time slot) or receiving PATH ACK (Need toapply for an optic fiber time slot), and stops at

receiving handover complete.

T3107(s) 10 The timer starts at old CCB (Call Control Block)

receiving message MSG_ASS_CH_READY from

new CCB, and stops at receiving assignmentfailure or internal clear command. Also starts atnew CCB receiving channel activation

acknowledge, and stops at receiving assignmentcomplete or internal clear request.

T3109(s) 27 The timer starts at delivering message CHANNEL

RELEASE, and stops at receiving messageRELEASE INDICATION.
