RNC WCDMA BTS


Creating Traffic DescriptorsThis page is not available if the Flexi HSPA Adapter (I-HSPA Adapter) is selected to be in use but the ATM Iu-PS/Iur is not in use

If the I-HSPA Adapter is not in use, you need to define at least four traffic descriptors: one for the BTS capacity on the VP level, one for the IUB signalling terminations, one for the AAL2 user path and one for the DCN interface.

If the I-HSPA Adapter is in use and the ATM Iu-PS/Iur is in use, you need to define at least five traffic descriptors: one traffic descriptor for each Iu- PS/Iur termination (Iu-PS Control Plane, Iu-PS User Plane, Iur Control Plane, and Iur User Plane) and one for the DCN interface


Configuring Iub Termination

Supported ATM interfaces are PDH and SDH interfaces, IMA groups, and pseudowires on a PSN tunnel

The IUB Terminations via One Virtual Path option is disabled and cleared if the configuration contains more than one ATM interface or pseudowire


UBR+ for Iub User Plane

If the UBR+ is enabled, enter the minimum desired cell rate in the Min. Desired Cell Rate field and the UBR share in the UBR Share field

Configuring Iub Transport – ATM over Ethernet, IP Iub, Dual Iub, DCN and IP Setting


Defining Physical layer configuration for Ethernet

Only one Ethernet interface can be selected to be in use, except for FTIB with Iub IP transport mode. When FTIB is using Iub IP mode, two Ethernet interfaces can be selected.


Defining Transport Address and Quality of Servicesettings

IP address/subnet of the enabled Ethernet Interface on TRS and the corresponding bandwidth.

Select ‘Include Ethernet Overhead’ to include Ethernet overhead in shaping.

This page is available if the FTIA, FTIB or FTJA unit is in the TRS and an Ethernet interface has been configured to be in use

In Dual Iub traffic mode, the path is used for user plane traffic, and in Iub IP mode it is used for all traffic

Defining ATM Over Ethernet settings - Pseudowire


Dual Iub for Flexi WCDMA BTSAllowing data traffic offload using

Ethernet interfaces at RNC and Flexi BTSsOperator benefits• significant cost savings in backhaul, like

with solution Hybrid Backhaul with Pseudo Wires

• no external pseudo wire gateway required at RNC site

• higher peak rates possible as with n*E1s

Dual Iub allows • offloading data traffic to alternative

Ethernet path using 3GPP Rel-5/Rel-6 compliant Iub/IP protocol stack

• any Ethernet physical layer (e.g. DSL, ng-SDH, adaptive modulation microwave..) may be used

• ATM/TDM for delay critical R’99 voice and data traffic as well as signaling traffic

Ethernet Ethernet


Defining Dual Iub settings 1/2

• With the Dual Iub feature it is possible to connect the BTS and the RNC by parallel ATM and IP paths

• The advantage of Dual Iub is that the high volume HSPA traffic which is not sensitive to delay and loss can be offloaded from the ATM path to the IP path.

• In Dual Iub configuration, the DCN is completely separated from the IP network for the User Plane

• These pages are available if :– the Flexi HSPA Adapter (FHA) is not in the configuration– there are FTIA, FTIB, or FTJA units in the TRS– an Ethernet interface with the Dual Iub transport mode has been configured

to be in use


Defining Dual Iub settings 2/2


IP based Iub for Flexi WCDMA BTS

• Flexi WCDMA BTS, Ultrasite WCDMA BTS and RNC support 3GPP Rel-5/Rel- 6 compliant Iub/IP protocol stack via integrated Ethernet interfaces

• Based on IPv4• Reduced planning and configuration effort due to

complete absence of ATM layer• Reduced maintenance costs, e.g. BTS rehosting is

basically just a change of an IP address• Priority marking on IP (ToS/DSCP) and Ethernet (VLAN

priority bits) layer

OPEX/CAPEX reduction by using cost efficient packet transport with 3GPP compliant IP/Ethernet Iub stack

3G BTS RNC


Defining Iub IP settings 1/2

• In Iub IP, the BTS and the RNC are connected via an IP/Ethernet network.

• Since all traffic is transported via the IP/Ethernet network, the network must be reliable enough and its delay and delay variation suitably low.

• These pages are available if :– the Flexi HSPA Adapter (FHA) is not in the configuration – there are FTIA, FTIB, or FTJA units in the TRS– an Ethernet interface with the Iub IP transport mode has been configured to

be in use


Defining Iub IP settings 2/2

IP signaling subnet within RNC. ICSU must be in this subnet!

ICSU – Interface Control and Signalling UnitSCTP – Stream Control Transmission Protocol UDP – User Datagram ProtocolCAC – Connection Admission ControlBFD – Bidirectional Forwarding Detection

BFD is a network protocol used to detect faults between two forwarding engines.

Far end IP address for BFD.


Timing over Packet

• Synchronization information, needed for running air interface with required frequency accuracy, can be provided to BTSs over high quality packet network (e.g. Metro Ethernet)

• Allows to keep costs low by obsolescing use of GPS or Hybrid Backhaul (simultaneous usage of TDM and packet backhaul) for synchronization

Solution includes:• Timing over Packet (ToP) Master Clock at RNC sending synchronization information to

BTSs. RNC site node can be used to connect ToP Master• FTIB in Flexi BTS (ToP Slave) for recovering clock signal from Timing over Packet data

Taking full advantages of packet transport for BTS backhaul

Defining Local Cell Setting


Defining WCDMA carrier candidates and local cellgroups

WCDMA carrier candidates are determined at the network planning stage. It is essential that the value input matches the expected value in the radio network plan. You should not select the values arbitrarily

Up to four different values can be defined for each frequency band. The frequencies are calculated according to the entered channel numbers and displayed in the Frequency MHz column

Note that if the System Module FSMB is used in the configuration, it is mandatory to use the Extension System Module to get the Local cell groups in useLocal cells with the same UARFCN value must belong to the samelocal cell group.

Parameter can be used to override nominal filter tuning to minimize noise to neighboring frequency band

Defining HSUPA Setting

In case of ‘Default in Use’ is selected for HSUPA Resource Allocation, baseband resources for HSUPA are allocated dynamically.In case of user defined resource allocation baseband resources are allocated statically based on number of HSUPA users and Minimum Baseband Decoding Capacity in Mbps.

For traffic with rate guarantees

Defining AISG MHA settings


Antenna Line Settings 1/7

MHA type: Other• the BTS doesn’t provide DC power to MHA, nor generates MHA alarm• MHA power supply has to be fed from an external source• UL/DL Delay in the MHA can be user-defined



NOKIA MHAs:WMHA – Single MHAWMHB – 2 single MHAs, separate power feedWMHC – Dual MHA, single power feed through its “BTS2” port.



for WMHC/WMHD only the WMHC/WMHD requires power supply through its “BTS2” port. This selection is made for the FRxx ANT port which is connected it.



for WMHC/WMHD only If an additional equipment behind the MHA requires power supply through antenna feeder, the voltage can be defined by the user or automatically set by the BTS.



for all MHA types the existence if Diplexers/Triplexers is to be defined for two reasons:- the additional loss is to be considered by the BTS for correct signal gain.- the additional delay affects the round trip time



for all MHA types - the number of Diplexers/Triplexers is to be defined:1: X-plexer on BTS side only, wideband antenna2: X-plexer on both sides, BTS and antenna3: With broadband antenna and MHAs

Round Trip time Delay:- calculated by the BTS Site Manager or…



Round Trip time Delay:- …user defined (after measurement)
