1 Overview

1.1 Presentation

Note: The logical configuration can be activated completely independently from thephysical connection of the BTS. Creating adjacencies and call tests must beconducted after the BTS is functional and connected to the network.

Coordination is needed between BTS and OMC-R sites to define the initialsettings. The Qmux address must always be set. For A9100/A910 BTSs, thetransmission mode is configured via OML.

The GPRS option is not applicable when the Abis chain to the BTS is passingthrough a satellite connection.

G1 MKII BTSs can only be used if they have a BIUMD card (Chain) and if theyare equipped with DRFU. They cannot be used if they have a BIU2M card (Star).If they have the BIU2M card, either the BTS or the card must be replaced.

G2 BTSs can only be used if they have a FUMO or DRFU card. They cannotbe used if they have a FUCO card, in this case either the BTS or the cardmust be replaced.

In order to create a required configuration it is also possible to add more thanone new BTS and more than one cell. In this case it is better to perform all thelogical parameters modification into a single PRC.

1.1.1 Cases

The following cases apply:

C1: BTS is installed on a new Abis. There is no traffic outage.

C2: BTS is installed on an existing Abis with downstream BTSs. This case

causes a traffic outage on the downstream BTSs.

C3: BTS is installed at the end of an Abis chain (no downstream BTSs).There is no traffic outage.

1.1.2 Options

The method takes into account one option:

O1 : Configuring the GPRS for the cells

O2 : Abis connection via satellite.

O3: Create cell(s) shared (applicable only for A9100 BTSs ).

1.1.3 Restrictions

None.

1.2 Preparation

1.2.1 Prerequisites

The following prerequisites apply:

BTS sites are clean, tidy and easily reachable.

The Abis is installed and tested.

For Case 2, the jumper linking the upstream and downstream BTSs has

been installed. This jumper is removed during this scenario.

BTS(s) is installed and commissioned.

For option O3: Clock synchronization cable(s) must be already installed

between BTSs involved into cell shared .

BTS(s) must be configured with the correct initial settings.

There are adequate resources to handle the new traffic channels and LapD.

All BTS SW packages and OMU-CPF are loaded in BSC memory.

1 Overview

1.2.2 Site Specific Information

You need the following site specific information:

Identification of cases and options to perform

BTS site topology

Case 1: Characteristics of the Abis (name, Qmux TS if BTS(s) to insert is

G1/G2 BTS).

Characteristics of the BTS(s) (family, HW generation, name, Qmux address,

number of sectors, mode of transmission, antenna diversity, master or

slave, Qmux TS for G1/G2 BTS).

List of cells to create with parameters value ( LAC, CI, frequency, TS

definition). The list has to be exhaustive.

List of cells supporting GPRS and parameters value ( RA code, RA color,

Min_Pdch, Max_Pdch_High_Load, Max_Pdch )List of adjacencies with parameters (list of impacted cells, direction of

the HO)

1.2.3 External Tasks

The following external task is to be taken into account:

1. All cells are declared at MSC site

2. Ask the personnel at MSC to perform a MSC database update for takinginto account the parameters for the new BTS.

3. In case of Option 2, check and update if needed the CRC4 for the Abis atthe BSC site.

4. Update adjacencies on neighbours OMCs if necessary

1.3 Scheduling

Table 1 describes the sites, personnel and duration of each Grouped task andthe total time to perform the scenario.

2.3 Scenario Description

The detailed tasks for adding a BTS are described below.

Note: Case specific tasks are marked with a C1, C2 or C3 in the Note column.Detailed Tasks that do not have C1, C2 and C3 in the note column are common

to all three cases and must be performed.To add a BTS to:

A new Abis, use Case 1 (C1)

An existing Abis with downstream BTSs, use Case 2 (C2)

A BTS to the end of an existing Abis (no downstream BTSs), use Case 3

(C3).

Options are marked with O1, O2, O3 in the Note column. Detailed tasks thathave O1, O2, O3 are applied only if that option is choosen.

2.3.1 Perform initial checks

Note:map each new cell

Use the Check All option ( without forcing celladministrative state) in Check PRC to check theparameters, hardware and telecom impact ofyour PRC1.

If the check produces error messages, correctthe configuration as required and re-attempt thecheck. Continue corrections and checks until noerrors occur.

2.3.5 Insert BTS

To minimize traffic outage, you must keep the time between the lock andunlock cells to a minimum.

For option O 3: Clock synchronization cable(s) must be already installed

between BTSs involved into cell shared . If the cables are not installed performthis installation using chapter Install Synchronization Cables form BTS SiteMaster/ Slave Synchronization scenario.


C1, C3 If not done previously, the BTS must bephysically connected to the new Abis link(use BTS Connection ).

C2 Inform the OMC-R you are ready to insert the

BTS into the Abis link.
