The Macro BTS solutions are composed of 2 main families.

The BTS 12000 family supplies an indoor solution with the BTS 12010 and an outdoor solution with the

BTS 12020. Both provide high capacity, large coverage, support of high power solution (up to 60W) and

full UMTS frequencies range (2100 or 900).

The BTS 6100 family provides an indoor compact solutions with the BTS 6110 and an outdoor compact

solution with the BTS 6120.

They provide Medium Capacity with large coverage solution.

Pico Node B

The extension of the BTS portfolio provides a large range of solutions for any situation.

For Hot spot coverage (high capacity for small coverage), you can use the micro Node and its main

features which are 128 Channel Elements with a 5W power.

For indoor coverage, its very low power allows to place the pico BTS close to where people are in

building, office location.

To use the maximum power at the antenna connector when high feeder losses are expected (tower), you

can replace the standard BTS solution by the combination of a Remote Radio Head (RRH) and a digital

Node B. We will detail this configuration in the coming slides.

For the digital solution, 2 main cases are deployed. In the first case, a digital BTS is located in the

equipment user space of a dBTS 2U, meaning that it takes the space of 2 units in a standard BTS user

space such as GSM BTS. It allows to have a cost-effective deployment in existing sites. From UA5.1, the

dBTS 4U might also be used to extend the capacity in terms of channel elements. In the second case, a

digital BTS is located in a compact cabinet. The dBTS 6100 can also be used with the RRH. In UA5.1, note

that the dBTS 6100 can also be associated with a remote part called the rBTS 6100, in order to create a

macro BTS, that can be easily transported in any location thanks to the split of the macro BTS functions

into 2 compact cabinets: dBTS + rBTS.

� the left compartment includes the power amplifiers, the RF combiners, the battery,

� the right compartment includes the functional modules, the RF combiners, the User space (4xU), the

rectifiers (UCPS rack), and the AC filtering.

The main enhancements are:

� Energy system: rectifiers and DC distribution are located in a rack, common with the 18020

GSM/UMTS.

� Cooling system: two fans (one for each compartment) instead of one.

� User space: four modules instead of three.

Compared to the AC only variant, the AC/DC integrates the following changes:

� The internal batteries are removed;

� The battery space houses a DC Connection Block;

� The rectifiers are replaced by fillers.

The DC input voltage range is -40.5 V up to – 57 V.

The AC main power is still required to power the heaters and the maintenance plug.

Here is presented the Remote Radio Head (RRH) configuration that is designed for macro-cellular

applications. RRH is basically a solution where the transceiver, the Multi Carrier Power Amplifier (MCPA)

and the filter functions are located remotely from the BTS.

In this particular configuration, the main functions of the BTS Digital shelf are network interface and call

processing.

The Remote Radio Head solution for UMTS is composed of two modules. The Optical Interface Module

(C3OIM) is located inside the UMTS BTS cabinet, in the Digital shelf. The Remote Radio Head is located on

the remote site.

The main functions of the RRH are signal processing, up and down frequency conversion, transmission

amplification with the Power Amplifier (PA) and coupling with the duplexer.

The Node B supports the following basic functions:

� Call processing: this includes channel setup and management for both common and dedicated

channels, cell management, power control, handover and measurement.

This function is in charge of the radio resource management inside the BTS. This function

manages the UMTS services and the internal services used for configuration and implementation

purposes.

The call processing function is also in charge of channel set-up and management for the common

and dedicated channels, cell management, power control, handover, and measurement.

� Network interface: interface management with the RNC, optional interfaces for enhanced

capacity or remote network connectivity.

� Uu interface (UMTS User interface): this interface is used between the BTS (Univity BTS)

and the UE (User Equipment). It is dependent on the technology used on the radio (for

example, it can be W-CDMA or TD/CDMA)

� Iub interface (Interface UMTS BTS): this interface links up the Univity RNC and the Univity

BTS

� Synchronization: to retrieve a highly stable radio frequency from the network interface.

Radio access and modem

This includes modulation / demodulation, frequency up / down-conversion, amplification.

Radio channel coding / decoding introduces redundancy into the source data flow, increasing its rate by

adding information calculated from the source data, in order to allow the detection or correction of

signal errors introduced by the transmission medium.

The channel coding algorithm(s) used and the amount of redundancy introduced may be different for the

different types of logical channels and different types of data.

Decoding function tries to reconstruct the source information using the redundancy added by the channel

coding function to detect or correct possible errors in the received data flow.

The Node B supports the following OA&M functions:

� Operation and Maintenance (see dedicated section further on)

� Alarm management

Event reports are sent by all pieces of equipment to the OAM platform in order to constantly

inform the system about the state of the whole network. Two types of even reports must be

carefully handled by the OAM system:

� Hardware anomalies automatically generate alarms which are forwarded up to the Alarm

Browser of Preside NSP.

� State changes usually generate notifications which are stored in the notification log file for

investigation purposes, later on.

� Configuration and Supervision

This function is in charge of configuring and supervising the modules which ensure inventory

information, reporting and plug & play management.

� Performance monitoring

This function performs measurements on radio channels (current and surrounding cells) and

translates these measurements into radio channel quality estimates. Measurements may include:

� Received signal strengths (current and surrounding cells)

� Estimated bit error ratios (current and surrounding cells)

� Estimation of propagation environments (high / low-speed, satellite, etc.)

� Transmission range (it means through timing information)

� Doppler shift, Synchronization status, …

TILTerminal

Active iCCM Passive iCCM or filler

The TIL Terminal is connected via a TCP/IP connection to the active iCCM.

This connection is either remote (called network connection) or local (called peer-to-peer connection).

TIL Network connection:

� The network connection is only applicable for an BTS in a live UMTS network.

� The TIL Terminal access is via the RNC to the BTS iCCM, on the IP-over-ATM interface. The iRNC acts

as a router for the IP messages.

� The TIL user has to know the public IP address of the iCCM module. This public IP address can be

fixed or dynamically assigned by a DHCP server.

� Note that the TIL does not handle dynamic IP address allocation of the iCCM: i.e, if the IP address of

the iCCM changes between two TIL connections, TIL operator has to know the new IP address of the

iCCM for the subsequent connection.

TIL peer-to-peer connection:

� The TIL terminal is directly connected to the iCCM module on the Ethernet debug port 10/100 BaseT.

� This debug port has the same hard-coded IP address. It is factory designed and is independent of the

iCCM. Thus the TIL user always knows the IP address used to access the iCCM for a peer-to-peer

connection. An IP aliasing mechanism allows the user to define several IP addresses on this same

interface.

Radiating BTS

The Radiating BTS command allows you to make the BTS transmission in stand-alone mode for the Radio Frequency tests. Two BTS modes are available:

� Normal mode

� Radiate mode

In Normal mode, the middle area section of the Radiating BTS window contains the following three columns:

• Alpha (Cell 1) • Beta (Cell 2) • Gamma (Cell 3)

Each column contains the following fields:

• State • Admin State • Maximum Transmission Power • Primary Scrambling Code

• Primary CPICH Power • Primary SCH Power • Secondary SCH Power • TMA present

In Normal mode, the bottom area section of the Radiating BTS window contains the following options:

� ACTIONS consist of three commands:

� Submit. This command determines if the value range of the parameters you entered is acceptable. If necessary, you can change the wrong parameter values (a list of radiating BTS parameters, which are site-specific and are compliant with the customer needs).

� Default. This command restores all default radiating parameters.

� Refresh. This command refreshes all current radiating parameters.

� RADIATING MODE consist of two commands:

� Start Radiating. This command is grayed out to indicate it is unavailable because the BTS mode is the Normal mode.

� Stop Radiating. This command is grayed out to indicate it is unavailable because the BTS mode is set to Normal mode.

� BTS MODE consist of commands:

� — Radiate. This command activates the Radiate mode.

� — Normal. This command is grayed out to indicate it is unavailable because the BTS Mode is set to Normal mode.

� Close quits the Radiating BTS window in Normal mode.




In Radiate mode, the top section of the Radiating BTS window contains the following fields:

• BTS Mode • Downlink Frequency • Frequency type (1900 or 2100)

Middle section of the Radiating BTS window in Radiate mode

In Radiate mode, the middle section of the Radiating BTS window contains three columns of

parameters:

• Alpha (Cell 1) • Beta (Cell 2) • Gamma (Cell 3)

Each column contain the following fields:

• State • Admin State • Maximum Transmission Power

• Primary Scrambling Code • Primary CPICH Power

• Primary SCH Power • Secondary SCH Power • TMA present

In Radiate mode, the bottom section of the Radiating BTS window allows setting the

following options:

� ACTIONS with three possible commands:

� Submit. This command determines if the value range of the parameters you

entered is acceptable. If necessary, you can change the wrong parameter

values (a list of radiating BTS parameters, which are site-specific and are

compliant with the customer needs)

� Default. This command restores all default radiating parameters.

� Refresh. This command refreshes all current radiating parameters.

� RADIATING MODE with two possible commands:

� Start Radiating. This command activates the Radiate mode.

� Stop Radiating. This command deactivates the Radiate mode.

� BTS MODE with two possible commands:

� Radiate. This command is grayed out, to indicate it is unavailable because the

BTS Mode is the Radiate mode.

� Normal. This command activates the Normal mode.

� Close. This command allows quitting the Radiating Bts window in Radiate mode.

IP Ping

The IP Ping command allows you to check the IP connection with the OMC-B.

The IP Ping window shows the following fields:

� OMC-B IP Address: displays the current address of the OMC-B (by default) which is stored in the Installation and Commissioning parameters.

� Ping Count: number of pings to perform (1 to 5)

� Last IP Ping Result: displays the result of the last ping action

� the bottom area of the window contains three commands:

� Default: sets the contents of the IP Address field to the configured OMC-B IP address.

� Ping: runs the test.

� Cancel: quits the ping test.

After selecting Ping, the IP Ping window displays the new result message.

ATM F4/F5 test

The ATM F4/F5 test involves the following steps:

� The ATM F4/F5 test must be initiated from the TIL GUI.

� The TIL sends a request to the CCM/iCCM.

� An ATM connection between the BTS and the RNC is created with the specific parameters

The number of sent messages is compared with the number of received messages. This report is sent to the TIL GUI.

� The previous ATM connection is canceled.

The ATM F4/F5 test is used to test the ATM link between the BTS and the RNC. This command is only applicable with a RNC in PCM configuration.

The ATM F4/F5 test can be started either from the BTS or initiated from the RNC through the ATM OAM flow.
