Introduction to Flexi Multiradio BTS WCDMA

1 Introduction to Flexi Multiradio BTS WCDMA This chapter gives a general overview of Flexi Multiradio Base Station WCDMA. Flexi Multiradio BTS WCDMA is a part of NSN 3G macro BTS site solution. From a BTS site installation and hardware point of view, Flexi Multiradio BTS introduces a new way to build BTS sites using modules, without a specific BTS cabinet. Because of its small weight and size, modular design and full frontal accessibility, Flexi Multiradio BTS is easy to install in various locations. From a feature and performance point of view, Flexi architecture provides a smooth evolution from UltraSite WCDMA BTSs, without compromising performance or capacity. Flexi Multiradio BTS modules can be used with different BTS configurations for an integrated site solution. The existing site support and auxiliary cabinets can be used to house Flexi Multiradio BTS modules, or modules can be installed, for example, on a wall. A Flexi Multiradio BTS consists of three types of RF Modules per frequency band and one System Module with a transmission sub-module. The same Multiradio modules are used in both indoor and outdoor sites. Flexi Multiradio BTS is designed for easy installation, commissioning, and maintenance. One person can carry the modules and install them on the floor or on the wall. Because of the modular solution, the footprint, space, weight and power feeding system of the site can be optimized. The acquisition time, cost, and acceptance time of a new site is reduced. Flexi Multiradio BTS does not require regular maintenance.

Features


6 Features 6.1 Cost-efficient modular site With Flexi Multiradio BTS WCDMA, the same equipment can be used to build coverage and capacity. A high WCDMA carrier-capacity and wide coverage per site means fewer sites, which makes building a WCDMA network more cost-effective. Flexi Multiradio BTS WCDMA can be installed in an existing Talk Family and UltraSite GSM/EDGE/WCDMA site for a data capability upgrade; Flexi Multiradio BTS WCDMA is designed to use most of the existing site equipment.

Easy installation A Flexi Multiradio BTS WCDMA module can be lifted, carried, and put into place by one person. The average module installation time is reduced compared to the previous WCDMA BTSs.

Features


Intelligent BTS Shutdown Intelligent BTS Shutdown with BBU Unit feature optimizes the investment to one battery backup system on a high-capacity BTS, especially on sites that operate as important transmission hub nodes. With intelligent shutdown, separate backup systems for BTS and transmission are unnecessary. The Flexi WCDMA BTS with battery backup system supports an intelligent BTS site power shutdown procedure in the event of an AC power failure. During the commissioning of each site, the operator can define different shutdown timers and priorities for the BTS sectors and carriers. Intelligent shutdown is activated from Power systems by activating one external alarm (EAC) lines to Flexi BTS. When the Flexi Multiradio BTS detects a problem with the power provisioning – so switching to battery power supply - an alarm will be raised and the BTS will automatically apply mechanism to reduce the required power consumption. By this the Flexi Multiradio BTS will then stay in field as long as the power lasts with reduced or no service offered.When the AC power is getting back, the Flexi Multiradio BTS offers full service again. The reduction of power is done via the stepwise shutdown of services which are triggered by operator configurable timers per BTS. Different shutdown scenarios can be configured for the BTS by setting these timers. Two timers with two different actions are steering the BTS behavior while working on batteries: • •

when the first timer is exceeded, selected number of cells will be switched off (for example 222 to 111) when the second timer is exceeded, all cells of that BTS will be switched off gracefully, means the UEs in that cell will be forced to change to a different cell.

The timer values can be configured via NetAct or with BTS SM. The setting especially of the first timer value shall consider the specific situation in the network. For example, a three-sector two-carrier Flexi WCDMA BTS (2+2+2) site equipped with battery backup operates as a transmission hub node towards other BTSs in a chain. The first timer can be set to shut down the second carriers of the BTS, to operate as 1+1+1 (for example) 30 minutes after an AC power failure. The second timer can be set to shut down the remaining 1+1+1 BTS (for example) one hour after the AC power failure, in order to support the transmission node for as long as possible with the existing battery capacity. Timers can be set according to the configuration and priorities of each site.

Reliable operation Simplicity and speed of maintenance procedures improve operation reliability. Maintenance is improved by module integration and automatic fault detection procedures. Special attention has been paid to Flexi Multiradio BTS WCDMA software start time, reducing, for instance, the downtime when a new software package is taken into use.

6.2 One BTS for all WCDMA network applications Flexi Multiradio BTS WCDMA is optimized for high-capacity and wide-coverage applications. It ensures cell ranges that meet the requirements of the coverage applications. Therefore, the number of sites required for building a WCDMA coverage is small. A seamless voice and data coverage area can be built easily. Flexi Multiradio BTS WCDMA has been developed for coverage applications. It offers: • • • •

high downlink power with 100 W Dual RF Module or 210 W 3-sector RF Module, optimum uplink performance and receiver sensitivity, outdoor modules that can be located close to antennas, reducing antenna feeder losses, optimized antenna system performance, including 3GPP antenna tilting and Mast Head Amplifier (MHA) support.

Antenna Line Optimized Antenna line is a separate optional site solution to further improve total BTS and antenna system site RF performance and to minimise costs.

Issue: 12B

Features


Flexi Multiradio BTS WCDMA Optimized Antenna line includes the following optional features, enabled by SW License keys (for further information, see License management): • • •

Integrated MHA power feeding and O&M control to the RF Module of the Flexi BTS Antenna line supervision by Return Loss measurement Integrated 3GPP standard Antenna Tilt power feeding and 3GPP Antenna Tilt O&M control to the RF Module of the Flexi BTS

Flexi RF Module has an integrated lightning protection circuit in all antenna connectors. The antenna connector of Flexi Multiradio BTS WCDMA is on the RF Module front panel. No additional units, connectors, or jumper cables are necessary between the Flexi Multiradio BTS WCDMA antenna connector and the antenna. This minimizes the antenna line length and losses and optimizes RF performance in both the uplink and downlink direction.

High-capacity HSDPA and HSUPA BTS Flexi Multiradio BTS WCDMA is a compact high-capacity voice and data BTS designed to support future High Speed Downlink Packet Access (HSDPA) based services and High Speed Uplink Packet Access (HSUPA) based services. Smooth HSDPA and HSUPA support is provided through SW. RF and System Modules simultaneously support existing voice, circuit, and packet data services. They also support HSDPA and HSUPA, meaning that no special HSDPA modules are necessary. The System Module can be used for high bit rates supported by HSDPA software. The processing capacity of the Flexi Multiradio BTS WCDMA can be configured to support the maximum capacity that the WCDMA air interface allows. In addition to flexible traffic capacity, Flexi Multiradio BTS WCDMA also allows a free mix of traffic patterns to accommodate whatever proportion of voice and data is required.

3GPP Iub compliant BTS Flexi Multiradio BTS WCDMA is fully compliant with the 3GPP Release 6 Iub standard interface between the BTS and the RNC. This makes multivendor RAN possible, after 3GPP Release 6 telecom Integration and Verification in a multivendor environment has been completed. Traffic from Flexi Multiradio BTS WCDMA O&M to the NetActTM network management system is carried in IP over ATM. Therefore, all NSN BTS-specific O&M traffic can be transferred transparently to any RNC.

6.3 Flexi Multiradio BTS WCDMA Feederless and Distributed Site concept Flexi Multiradio BTS WCDMA Feederless and Distributed Site Solutions refer to a situation where the System Module and RF Modules or Remote Radio Heads are installed apart from each other. The benefits of the Feederless and Distributed Site Solutions compared to a traditional BTS site are listed below: • • • •

18

Overall site RF performance is better compared to traditional installation. Uplink and downlink performances are 2 - 5 dB better compared with typical 30 - 80 meter long antenna feeders. The solutions open easier, new and optimized installation possibilities especially with difficult places. There is no need for mast head amplifiers.

DN7087165

Issue: 12B


Features

Flexi Multiradio BTS WCDMA Feederless and Distributed Site solutions utilise various power distribution solutions. DC feed to the feederless or distributed site is provided either by a NSN power system or third-party products. The input for the System Module is floating 48 VDC. There are five basic power supply alternatives for the BTS site and its modules: • • • • •

Flexi Power Module (FPMA) with a site support module, batteries, and cabinet FPMA installed in the proximity of the RF Module FPAB for a single RF Module Flexi Power Rectifier (FPRx) third-party AC/DC system (must meet the ETSI 300 132-2 standard)

6.3.1 Feederless site In the feederless site solution, the distance between the System Module and the RF Module or Remote Radio Head is up to 200 m, when using preconfigured optical cables. The feederless site solution can be used, for example, on a rooftop BTS site as shown in figure Feederless rooftop site. If the modules are installed on a rooftop, Flexi RF Module can be installed very close to the antenna. This enables connecting the RF Module to the antenna with a short jumper cable. When DC is fed from the DC power system (200 m measured from the power system equipment) to the RF Module or Remote Radio Head, the maximum distance is 200 m. The BTS site can be either DC or AC powered. In the latter case, an AC/DC converter (either the FPMA or a third-party converter) is required. Figure 6

DN70161455

Optical cable installation between the System Module and the RF Module or Remote Radio Head can be done with the following alternatives: • •

Issue: 12B

One 50 m or 100 m optical cable. By splicing and cutting optical cables on sites where a certain optical cable length is required.

Overvoltage protection is required in installations with a risk of overvoltage by induction or indirect lightning. This functionality is implemented using Flexi System External OVP (FSEC) or Over Voltage Protection (FSES). Furthermore, the FSEC is used for joining a thick long DC cable and the Flexi RF Module or System Module DC cable. Protection level of FSEC/S is 15kA (Class II).

6.3.2 Distributed site In the distributed site solution, the distance between the System Module and RF Modules or Remote Radio Heads can be up to 15 km. The existing optical fibres can be utilized and equal benefits as in the feederless site concept achieved. The RF Module and System Module can be attached to the existing optical fibre network by using a 2 m single mode optical cable that has IP55 protection in the RF Module and System Module end of the cable. Single mode components and single mode transceivers are used for connecting the System Module to the RF Module. A typical distributed site is a pole installation. The power distribution to the RF Module is local and can be either DC or AC (an FPMA next to the RF Module or a third-party system). Depending on the location of the RF Module, overvoltage protection might be needed. Overvoltage protection is required in installations with a risk of overvoltage by induction or indirect lightning. Optional overvoltage protection functionality (Class II) is implemented using Flexi System External OVP (FSEC) for DC feeding. The FSEC is needed in places where the 3U RF Module or the long DC feeder cable between the RF Module and FPMA is susceptible to indirect strokes. Furthermore, the FSEC is used for joining a thick long DC cable and the Flexi

Features

RF Module or System Module DC cable. Remote Radio Heads have integrated Class II overvoltage protection, so no external OVP is required at the RF Module end. In case AC input is used, overvoltage protection has to be carried out locally.

Flexi System Module Capacity Evolution


7 Flexi System Module Capacity Evolution Flexi System Module capacity is designed to support flexible and cost-optimized site capacity evolution. Traffic capacity Standard Operating SW of the System Module rel. 1 (FSMB) includes support for 32 Channel Elements (CE) to be used for Common Channels. Standard Operating SW of the System Module rel. 2 (FSMC/D/E) includes support for Common Channels for 6 cells/10 km or 3 cells/20 km. The available baseband capacity of Flexi Multiradio BTS WCDMA can be optimized depending on the BTS configuration and the required traffic capacity of the BTS site. More capacity can be enabled by activating HSxPA Processing Set License Keys or Rel99 Channel Element License keys.

Processing Sets Processing Sets are capacity units defined by # users / HSxPA throughput. Licenses for processing sets are BTS licenses as any other licenses. HSDPA • • •

HSDPA BTS Processing Set 1: up to 32Users/7.2 Mbps per BTS HSDPA BTS Processing Set 2: up to 72Users/21 Mbps per BTS HSDPA BTS Processing Set 3: up to 72Users/84 Mbps per BTS

HSUPA •

HSUPA BTS Processing Set: up to 24Users/5.8 Mbps per LCG

HSPA licensing is valid for Flexi System Modules FSMC/D/E.

Rel99 Channel Elements License Keys Both FSMB System Module and FSMC/D/E System Modules use Rel99 Channel element License keys to enable Rel99 capacity.

Management and software

8 Management and software 8.1 Local Management Tool WCDMA BTS Site Manager software is used to manage Flexi Multiradio BTS WCDMA commissioning, supervision, maintenance, and testing, as well as transmission configuration. Figure 8

WCDMA BTS Site Manager main view

Flexi Multiradio BTS WCDMA site can be controlled remotely by opening a WCDMA BTS Site Manager session at a remote RNC/Flexi Direct RNC or NetActTM site. The manager PC is connected to the BTS by means of an Ethernet connection locally at the site or remotely by specifying the IP address in the Site Manager. The site manager SW package includes the following:

Issue: 12B

DN7087165

23


• •


The WCDMA BTS Manager including antenna line and antenna equipment control and management The FlexiTransport Manager, for transmission management

WCDMA BTS Site Manager runs in the following environments: • • •

Microsoft Windows 2000, XP, Vista, and 7 Windows Server 2003 Red Hat Enterprise Linux 4 ES GNOME desktop

Flexbus-related configurations are performed with FlexiHub Manager.

8.2 Configuration management Once the BTS is in normal operation, a polling process is used to check possible changes in the BTS configuration. When modules are added to or removed from the BTS, the information in the HW database changes.

8.3 Remote User Event Log Management Remote User Event Log Management (RUEM) is a feature that allows a network management system (NMS) to trace operations done in network elements (NEs) by different users. This functionality is sometimes called “Audit Trail”. User access and operations might be successful or fail and in both cases this is logged. Figure 9

Audit trail

With RUEM, operations are logged on FTM/FCT and sent to NetAct within one single RUEM log file. NWI3 logged operations: • • • •

Login attempts (successful + unsuccessful) Logout Configuration changes (on fragment level) Local account updates

HTTP logged operations: • •

Reboot operations Reset to factory default operation

8.3.1 RUEM concept - how does it work? RUEM correlates each management operations with each user: • •

NWI3 and XOH management operations implements session concept (username/password) HTTP operations which are logged is operations which required username/password

Figure 10

The RUEM concept

Notification - Watermark Operations that are logged by RUEM are stored in FTM/FCT in a ring buffer (internally).This buffer is filled up for each logged operation. As soon as a critical value (that is watermark, ~70% of total buffer size) is reached, FTM/FCT sends a notification to NetAct (mediated by OMS in Flexi).

The RUEM upload mechanism 1. Triggered by NetAct

Issue: 12B

DN7087165

25



2. Triggered by Network element (FTM/FCT) - if the Watermark level is reached

After a successful reading of the logfile by the NMS the read logfile is deleted from the BTS to free memory space for the next log entries. Log files in the BTS are kept in nonvolatile memory and thus data is not lost upon power breaks. Exception: In case NetAct still does not upload the RUEM log file, the buffer might fill up to its maximum size and even exceed this. In latter situation the buffer has an overflow, some old information gets lost permanently. It is not recoverable! This special event called as wrapped-over event. This should be logged in RUEM log file.

8.4 Software updates Flexi Multiradio BTS can store two software packages in its memory. The software can be loaded either locally, with the BTS Site Manager software, or remotely from NetAct TM. Site visits are unnecessary for routine O&M tasks. Typically, local software downloading is done only when the NetActTM connection is missing, such as during commissioning. Flexi Multiradio BTS software can be downloaded as a background operation without interrupting the operation of the BTS. The new software can be activated at any time. Reboot is required in order to take the software into use. Flexi Multiradio BTS only uses downloadable software. All software can be downloaded and updated from NetActTM. This procedure is centralised, meaning that several BTSs can be upgraded with the new software either simultaneously or one by one. Flexi Multiradio BTS keeps the current and old software packages in its flash memory. Either of these software versions can be activated at any time. Reboot is required in order to take the software into use. Updated softwares (current and previous) in the BTS can be seen through BTS Site Manager/NetActTM.

8.5 External alarms and controls Electrically, Flexi Multiradio BTS WCDMA provides external alarms and controls similar to UltraSite WCDMA BTS. The BTS alarms and control inputs and outputs can be configured and tested locally at the BTS site with WCDMA BTS element manager SW. Up to 24 user-definable external inputs and six (6) user-controllable outputs are available and can be freely configured during commissioning to support different observation or control needs at the BTS site. Flexi System External Alarm (FSEB) should be used if old UltraSite or TalkSite alarm connections, or more than 12 alarm inputs, are used. If control outputs are used the maximum cable length is 15 m (49.2 ft). In normal operation, the BTS’s external alarms and control outputs are managed from NetActTM after they have been configured. External alarms and control outputs are available from the System Module but not from the Extension System Module.

8.6 SW upgrade and licensing Regular SW upgrade does not have an impact on the existing license files in network elements. The old functions work with the old license files. For new functions that are introduced with the new SW release, corresponding license files must be obtained and distributed to the network elements to activate the feature. In later releases, license files can be distributed to the network elements before the SW release upgrade. New license files are taken into use only when the corresponding SW release is activated in the network element.

Issue: 12B

A topology upload is needed so that the Network license Manager application receives the correct target identifiers to be used in licensing. The lack of a license does not affect the (remote) management access to the base transceiver station (BTS) in the field. Missing licenses might cause interruption to the services after the software upgrade.

9.2 Mechanics All Flexi Multiradio BTS modules are outdoor-capable, weather-sealed and at least IP55 class protected. Flexi Multiradio BTS modules consist of the following main parts: •

•

•

• • •

Module core. The core mechanics, with installed gaskets in all of the connectors, shield the module core against water, snow, and solid foreign objects, and make the module core IP65 weatherproof. The core mechanics also provide EMC shielding. Module casing. This provides fixing points for modules to the plinth and supports the stack of modules. The module core can be changed even if the module is at the bottom of the module stack. Fan assembly. This provides fresh air to cool the module. Each module controls its own fans according to temperature information, and two redundant fans enable module operation at normal temperatures, even with one fan. The fan sub-module can be changed in an operational module at a site where back access is provided. Module cables. All cables are IP55 protected. Optional Front and Back covers for BTS site installations without a cabinet. or Optional cabinets: – – –

Iub connection to RNC (Transmission connectors) The connectors for the Iub are located on the front panel of the transmission sub-module (FTxx). The cables are routed to the side of the System Module.

BTS Element Management port (LMP) An Element Manager PC can be connected to the management port connector at the System Module, for commissioning, operations, maintenance, and testing of the BTS. An RJ45 Ethernet connector is used.

Antenna connectors (Ant 1-6) The antenna feeders are connected directly to the RF Modules. With three dual power amplifier RF Modules the maximum number of antenna connections is 12. The antenna connector type is 7/16 .

Ethernet control bus These interfaces can be used to carry initialisation data, control data, and signalling data from the BTS to any auxiliary equipment that has an Ethernet port and an IP address.

Power feeding (Power supply connectors) A Flexi Multiradio BTS site has one common DC input power supply that is connected to the System Module. The System Module distributes DC current to the RF Modules and to a second System Module operating in baseband extension mode. The AC connector is at a separate optional AC/DC Module.

External alarms and controls (EAC) One EAC connector is located at the System Module. A separate weather-protected EAC connector box (FSEB) can be used to ease the connection of each physical alarm and control wire. One optional Flexi System OVP IP55 protected box for power lines (FSEC) can be used to weather protect overvoltage protectors (OVP) of the DC or AC power lines of the BTS site.

External Synchronization Input (Sync in) When using this hardware connector, Flexi Multiradio BTS WCDMA can be optionally synchronized with an external clock signal (for instance GPS, 2 or 10 MHz signal) when Iub transport is not providing clock reference signal, for instance, when Iub over Ethernet does not carry clock reference.

External Synchronization Output (Sync out) Flexi Multiradio BTS WCDMA can provide clock reference signal to other co-located BTS nearby (2G, 3G and future BTS).

GSM/EDGE and WCDMA co-siting

10 GSM/EDGE and WCDMA co-siting Flexi Multiradio BTS WCDMA is designed so that it is compatible with existing BTSs and it is easy to install on an existing site.

Mechanics Flexi Multiradio BTS WCDMA modules have much smaller space requirements than those of the Talk family and UltraSite EDGE/WCDMA BTSs. Floor installations of modules can be done using the same fixing points.

Power system When Flexi Multiradio BTS WCDMA is installed to an existing GSM/EDGE BTS site, the same connection types and power supply types can be used. The existing alarm connections, for example, the fire alarm and door alarm, can also be connected to Flexi Multiradio BTS WCDMA.

Antennas To minimise the work in adding WCDMA antennas to GSM BTS sites, part of the existing antenna infrastructure can be reused. A diplexer is an attractive way to add the Flexi Multiradio BTS WCDMA to the existing site, if the additional loss can be tolerated in the antenna line. Actual losses depend on the combination but (for example) in the case of GSM 900/WCDMA, the typical loss is less than 0.5 dB. NSN supplies diplexers for all necessary combinations. The Multi Radio Combiner (MRC) solution makes it possible to build an antenna line sharing site with a minimum effect on existing system performance. Downlink causes only a slight degradation for the BTS performance. A typical downlink loss is less than 0.6 dB. The Mast Head Amplifier (MHA) retains the uplink performance. There are three different MRC units that cover the bands: 850 MHz, 900 MHz and 2100 MHz. The MRC 850 and MRC 900 units give the possibility to co-siting GSM EDGE and WCDMA BTSs in the same frequency band through antenna line sharing. There are no limitations to system frequency allocation (G-G-W, G-W-G, W-G-G). The MRC 2100 unit allows WCDMA and WCDMA BTSs co-siting in the same frequency band through antenna line sharing. Using MRC units makes it also possible to co-site third-party BTSs.

Flexi Multiradio BTS WCDMA mounting kits for GSM/EDGE BTS Flexi Multiradio BTS WCDMA modules can be installed inside an existing GSM/EDGE cabinet. The following mounting kits are available for that purpose: • • • • • • •

Issue: 12B

Talk Conversion Kit (EMIA/EMIB) Flexi Mounting Kit Vertical for 2G (FMUA) Flexi Mounting Kit Horizontal for 2G (FMUB) Flexi Mounting Kit for WODA (FMUH) Mounting Kit for NB Flexi Outdoor (FMUG) Mounting Kit for WREB (FMUJ) 4U Mounting Kit for UltraSite EDGE (FMUM)
