Flexi Multiradio 10 Base Station can be installed on a wall, poll, or floor. It fits in the existing legacy GSM/EDGE/CDMA/WCDMA BTS footprints as well. Flexi Multiradio 10 BTS outdoor is protected to at least IP65 level and can be installed as such at an outdoor site. In addition, both indoor and outdoor cabinet installation options are available. Installation locations for a Flexi Multiradio 10 Base Station can be smaller than or the same as those reserved for previous BTSs.

5.5 Flexi Multiradio 10 Base Station - SW configuration overview Overview of Flexi Multiradio 10 Base Station SW configuration. Flexi Multiradio 10 Base Station can be SW-configured according to requirements of a given radio technology - GSM/EDGE, WCDMA/HSPA+, or LTE (TD/FDD). Additionally, many SW-definable features can be activated by the software. For example: • • • • • • • • • •

g

sector activation (one, two, or three sectors active of a 3-sector RF Module) RF power mode for active sector (8, 20, 40, 60, or 80 W) LTE cell bandwidth (1.4, 3, 5, 10, 15, or 20 MHz) MHA support and control Antenna Tilt support and control dual band and multiband support four-way uplink diversity mode 4TX MIMO downlink mode transport interface synchronization method (for example, GPS, timing over packet) The full feature list for each RAT can be found in Feature List document.

5.6 Flexi Multiradio 10 Base Station - acoustic noise About low acoustic noise of Flexi Multiradio 10 Base Station. The acoustic noise produced by a Flexi Multiradio 10 Base Station site is low because of reduced power consumption and an increased unit integration level. Site acceptance is easier, especially at urban outdoor sites. Fan speeds and acoustic noise are adapted to the BTS load and ambient temperature.

5.7 Flexi Multiradio 10 Base Station - commissioning overview About simplicity of Flexi Multiradio 10 Base Station commissioning.

16

DN0971928

Issue: 01I



The autodetection feature of Flexi Multiradio 10 Base Station makes commissioning and integrating fast and easy. The commissioning wizard guides the user step-by-step through the whole commissioning process. At the end of the process, the commissioning wizard produces a BTS Commissioning Report.

5.8 Flexi Multiradio 10 Base Station - operation and maintenance advantages About fast and simple maintenance of Flexi Multiradio 10 Base Station. Simplicity and speed of maintenance improves operational reliability. Maintenance is improved by module integration and automatic fault detection procedures. Special attention has been paid to Flexi Multiradio 10 Base Station software start time, reducing, for instance, downtime when a new software package is put into use.

5.9 Intelligent shut-down concept Definition of the intelligent shut-down feature. Intelligent shut-down 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 shut-down, separate backup systems for BTS and transmission are unnecessary.

5.10 Intelligent shut-down in Flexi Multiradio 10 Base Station About the intelligent shut-down feature activated in Flexi Multiradio 10 Base Station. Flexi Multiradio 10 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 Flexi BTS detects a problem with the power provisioning - so switching to battery power supply - an alarm is raised, and the BTS automatically reduces the required power consumption. As a result, Flexi BTS is operating with reduced or no service offered as long as there is enough power. Once the AC power is restored, the Flexi 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 steer the BTS behavior while working on batteries:

Issue: 01I

• •


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 NetActTM or with BTS Site Manager. The setting especially of the first timer value shall consider the specific situation in the network. For example, a three-sector two-carrier Flexi Multiradio 10 BTS WCDMA (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. Figure 2

5.13 Flexi Multiradio 10 Base Station - data and voice capacity About Flexi Multiradio 10 Base Station's flexible traffic capacity. Flexi Multiradio 10 Base Station is a compact multi-purpose BTS designed to support all future high speed broadband data and voice services over an air interface. Smooth data and voice capacity evolution is provided through software. The processing capacity of Flexi Multiradio 10 Base Station can be configured to support the maximum capacity that the air interface allows. In addition to the flexible traffic capacity, Flexi Multiradio 10 Base Station also allows a free mix of traffic patterns to accommodate whatever proportion of voice and data is required. Depending on network capacity requirements, the capacity installed can be matched with the capacity of the air interface.

5.14 Flexi Multiradio 10 Base Station - feederless site vs distributed site Overview of the feederless BTS site solution's advantages over the distributed site solution. Standard Flexi Multiradio 10 Base Station modules support the Feederless BTS site application where one RF Module, Remote Radio Head, or the entire Flexi BTS is installed close to the antennas. For a feederless site, traditional long antenna feeders or masthead amplifiers are not needed thanks to which the BTS site RF performance is optimized in both uplink and downlink. The benefits of feederless sites are: • • • • • •

Better RF performance because there are no downlink and uplink feeder losses. Easier installation because of reduced cabling to the tower. No long antenna feeders (typically six for a three-sector site). No masthead amplifiers/tower-mounted amplifiers. Reduced total wind load and weight. Reduced total power consumption.

RF Module and Remote Radio Head can be software-activated and configured to support one, two, or three sectors, or one sector with 2TX MIMO with optional four-way uplink diversity. In the Distributed Site solution, RF Module(s) or Remote Radio Head(s) are located up to 20 km away from the main Flexi System Module site.

Flexi Multiradio 10 Base Station - Single RAN aspects

6 Flexi Multiradio 10 Base Station - Single RAN aspects 6.1 RF Sharing 6.1.1 RF sharing overview Overview of the RF sharing concept. The RF sharing feature allows Flexi Multiradio BTS RF Module to operate in a concurrent mode with two Radio Access Technologies (RATs). BTS resources between RATs are allocated and shared by allowing two Flexi EDGE/WCDMA/LTE System Modules to share the same Flexi BTS Multiradio RF Module or Remote Radio Head (RRH). RF Module or RRH transmits RF carrier signals for two or more RATs at the same frequency band. The RF Sharing concept simplifies the antenna system complexity, and provides the operators with future-proof BTS site evolution. Figure 3

Multiradio BTS site

The BTS site backhaul traffic can be aggregated on one integrated IP/Ethernet interface by utilizing integrated QoS aware Ethernet switching. Synchronization Hub feature can be used for reference clock distribution on the BTS site.

6.2.1 QoS Aware Ethernet Switching overview Overview of the QoS Aware Ethernet Switching feature. QoS Aware Ethernet Switching allows multiple Ethernet interfaces in the BTS to be connected through the integrated Ethernet switch. One of the interfaces is used for the backhaul connection, while others might be used to connect other BTSs (at the same or another site). It is also possible to daisy chain several network devices. The Ethernet switch is VLAN- and QoS-aware. The egress traffic of the switch can be shaped to meet the bandwidth limitations of the backhaul network. Additionally, a policy can be applied to the ingress traffic to protect the BTS from the interface overload.

g

Ethernet switching is required at the BTS where the layer 2 traffic aggregation/daisy chain is to be implemented.

6.2.2 Flexi Multiradio 10 Base Station System Module as a synchronization hub Overview of synchronization in Flexi Multiradio 10 Base Station System Module.

Issue: 01I

Each System Module can act as a synchronization hub for other near-located System Modules. For example, it can output 2.048 MHz SynchOut based on any available synchronization source. If PDH interfaces are available in the System Module, they can also be used for synchronization distribution to other devices. If the BTS loses all sync sources, it switches to hold-over mode. Then, the BTS Oven Controlled Crystal Oscillator (OCXO) keeps running with the last known control value, and still provides the sync output.

8.2.3 Remote User Event Log Management - overview Definition of the Remote User Event Log Management concept. 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. In both cases this is logged. Figure 9

The RUEM concept

8.2.6 Remote User Event Log Management - logged operations storing About storing of the Remote User Event Log Management logged operations. Operations that are logged by RUEM are stored in 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, FCT will send a notification to NetActTM (mediated by OMS in Flexi).

8.2.7 Remote User Event Log Management upload mechanism How the Remote User Event Log Management logfiles are uploaded to NetActTM. 1. Triggered by NetActTM

32

DN0971928

Issue: 01I



2. Triggered by Network element (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 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 NetActTM still does not upload the RUEM log file, the buffer might fill up to its maximum size and even exceed this. In the latter situation the buffer has an overflow and some old information gets lost permanently. It is not recoverable. This special event is called a wrapped-over event. This should be logged in RUEM log file.

8.3 Flexi Multiradio 10 Base Station configuration management About tracking Flexi Multiradio 10 Base Station configuration changes. 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 hardware database changes.

8.4 Flexi Multiradio 10 Base Station software updating About updating Flexi Multiradio 10 Base Station software. Flexi Multiradio 10 Base Station can store two software packages in its memory. The software can be loaded either locally, with the BTS Site Manager software, or remotely from NetActTM. Site visits are unnecessary for routine operation and maintenance (O&M) tasks. Typically, local software download is done only when the NetActTM connection is missing, for example, during the commissioning process. Flexi Multiradio 10 Base Station software can be downloaded as a background operation without interrupting the BTS operation. The new software can be activated at any time. Reboot is required in order to put the software into use.

Issue: 01I

DN0971928

33



Flexi Multiradio 10 Base Station only uses downloadable software. All software can be downloaded and updated from NetActTM. This procedure is centralized, meaning that several BTSs can be upgraded with the new software either simultaneously or one by one. Flexi Multiradio 10 Base Station keeps the current and previous software packages in its flash memory. Either of these software versions can be activated at any time. A reboot is required in order to put the software into use. Updated software (current and previous) in the BTS can be seen through BTS Site Manager/NetActTM. The RF Module and RRH SW is updated automatically during Flexi Multiradio 10 Base Station SW update.

8.5 Flexi Multiradio 10 Base Station - configuring external alarms and controls How to configure and test Flexi Multiradio 10 Base Station external alarms and controls. BTS inputs and outputs can be configured and tested locally at the BTS site with Flexi Multiradio BTS Site Manager software. Six user-defined external inputs and six usercontrolled inputs/outputs are available and can be freely configured to support various observation or control needs at the BTS site. In normal operation, the external alarms and control outputs of the BTS are managed from NetActTM after they have been configured.
