1 Overview

1.1 Presentation

This scenario describes how to create and configure extended cells.

The maximum range defined in GSM for the access to a cell is 35 km. Thegoal of an extended cell is to increase the maximum distance between the

BTS and the MS, without changing the Air interface, to 70 km. Two differentcells are combined in order to create the extended cell. One cell (ExtendedInner) covers the range from 0 to 35 km and another cell (Extended Outer)covers the range from 35 to 70 km.

According to the engineering rules:

For 9100 BTS, the extended cell allows for several non -hopping TRXs

Extended cells are supported only on 9100 BTS with SUMA

LCS is supported on extended cells

GPRS is supported on extended cells

Both GSM and DCS frequency bands are allowed for extended cells

3 extended cells per BTS are allowed: 3 times (inner + outer)

Multiple CCCH is not supported in Extended Cell.

1.1.1 Cases

The following cases apply:

C1: Create Extended Cell

C1.1: Create Extended Inner Cell

C1.2: Create Extended Outer Cell.

C2: Modify Single Cell to Extended Cell

C2.1: Modify Single Cell to Extended Inner Cell

C2.2: Modify Single Cell to Extended Outer Cell.

Note: You can combine different cases to create the required configuration:

To create an complete Extended Cell, use a combination of C1.1and C1.2

If one cell is already created, use a combination of C1.1 and C2.2 or C1.2

and C2.1

If both cells must be modified, use a combination of C2.1 andC2.2.

1.1.2 Options

O1: GPRS on extended cell can apply.

1.1.3 Restrictions

None.

If the Extended Inner or Outer Cell has GPRS, useSet Cell Telecom Parameters to check and modify(if necessary) the GPRS parameters as follows:

MAX_PDCH, MAX_PDCH_HIGH_LOAD and

MIN_PDCH must have even valuesNB_TS_MPDCH must be set to 0 when the cell

type is Extended Inner / Outer

MAX_EGPRS_MCS is MCS4 for Extended

Outer and MCS9 is for Extended Inner

EN_NACC, EN_PSI_STATUS and

EN_STREAMING are disabled.

Note:If LCS was activated on thecell, and the operator wants to keep itactivated, do not set MAX_PDCH=0 on

these cells.

To configure GPRS on a cell:

Set the Routing Area Code

Set the Routing Area Color

MAX_PDCH, MAX_PDCH_HIGH_LOAD and

MIN_PDCH must have even values

NB_TS_MPDCH must be set to 0 when the cell

type is Extended Inner / Outer

If LCS with AGPS is activated, you can also modifythe EN_CONV_GPS, EN_MS_Assisted_AGPSand EN_MS_BASED_AGPS parameters.

To have EGPRS on the extended cell:

Both inner and outer cells must have EGPRS

declared (the EN-EGPRS parameter is set to

Enable)

All TRXs from inner and outer cells mustsupport EDGE (all TRXs are TRAs).

Note:

To have GPRS on the cell,

Trx_Pref_Mark must be 0 for at least

one TRX.To modify it for a block of TRX,use the Java Script Set/UpdateCircuit/Packet Mark ConfigurationUsing Script.

To modify only one cell, use the

edit cell command (see Set Cell

Set the Routing Area Color

MAX_PDCH,

MAX_PDCH_HIGH_LOAD

and MIN_PDCH must have even

values

NB_TS_MPDCH must be set to

0 when the cell type is Extended

Inner / Outer

MAX_EGPRS_MCS is MCS4 for

Extended Outer

EN_NACC, EN_PSI_STATUS

and EN_STREAMING are

disabled.

When GPRS is created on the cell,you can also modify the followingparameters:

Min_PDCH

NB_TS_MPDCH

Max_Pdch_High_Load

En_fast_initial_GPRS_access

Ps_Pref_Bcch_Trx

max_GPRS_Cs

max _EGPRS_Mcs

En_EGPRS

If LCS with AGPS isactivated, you can alsomodify the EN_CONV_GPS,EN_MS_Assisted_AGPS andEN_MS_BASED_AGPS parameters.

To have EGPRS on the extendedcell:

Both inner and outer cells must

have EGPRS declared (the

EN-EGPRS parameter is set to

Enable)

All TRXs from inner and outer

cells must support EDGE (allTRXs are TRAs).

Note:

To have GPRS on the cell, Trx_Pref_Mark must be 0

for at least one TRX.To modify it for a block of TRX, use the Java Script Set

/ Update Circuit / Packet Mark Configuration UsingScript.

To modify only one cell, use the edit cell command

(see Set Cell Telecom Parameters)

If En_fast_initial_GPRS_access is set to Enable,

respect the following rule:Min_PDCH >= En_fast_initial_GPRS_access +

NB_TS_MPDCH.
