1 Activating IP based Iub for Flexi WCDMA BTSPurposeFollow the procedure below to activate feature RAN74: IP based Iub for Flexi WCDMA BTS.

For more information on the feature, see RAN74: IP based Iub for Flexi WCDMA BTS in WCDMA RAN, rel. RU10, feature descriptions.

Exemplary reference configurations using this feature are presented in Configuring WCDMA RAN transport document.

The configuration examples in the activation instructions use the IP addressing pre-sented in figure IP-based Iub connectivity for Flexi WCDMA BTS.

Figure 1 IP-based Iub connectivity for Flexi WCDMA BTS

Before you startEnabling IP-based Iub requires the following interface units in the RNC:

in RNC2600, the NPGE Gigabit Ethernet interface unit - RAN77: RNC Ethernet Physical Interface feature

in RNC196/450, IP-interface upgrade - RAN1225: IP Interface Upgrade for RNC196 and RNC450 feature

In the Flexi WBTS, an FTIA, FTIB, FTJA, FTFB, or FTLB hybrid PDH/Ethernet transport sub-module is required.

The feature is an optional application with a separate license control.

This feature belongs to the application software. Before you activate the feature, make sure you have a valid license (a file including the feature information) installed. Before a licensed feature can be activated, the license must be transferred and installed in the RNC. For information on transferring the license to the RNC, see License management operations in RNC in WCDMA RAN license operation.

You can install the license by using NetAct or a local MML interface. If you install the license using NetAct, the feature covered by the license is automatically set to the ON state. If you use the MML interface, you must also set the feature state (ON/CON-FIG/OFF). In new installations, the default state is OFF. When installing a new incre-ment, the previously set state remains as the default.

For the specific instructions on the license installation in the RNC, see W7L INSTALL OR UPDATE LICENCE in W7 - Licence and Feature Handling.

For more information, see Licence-based feature management, W7 - Licence and Feature Handling, and License management principles. See also System Administration Principles in NetAct Product Documentation and Licensed sales items in RU20 in License management in WCDMA RAN.

Use the ZW7 command to activate the license for the feature with feature code 1079. Note that the license is capacity based, and the measure of the capacity is the number of BTSs.

If the IP-based Iub is not ON, the IP based route ID cannot be configured.

RNW configuration has to be done according to the network plan. Configuration can be created by using either the RNW object browser (RNC EM application) or the RNW plan interface. The IP-layer configuration can be managed using the local MML interface or the IP plan interface from NetAct.

BTS parameters can be configured with the BTS Site Manager or NetAct. For more information about BTS parameters, see Plan Editor Flexi Transport Module Parameters.

Restart of the WBTS is required after activation of this feature.

g In case RNC and BTS are configured to the same Layer 2 broadcast domain(s) (for example to the same VLANs), the IP addressing used for the user plane traffic and BFD sessions termination requires a special emphasis. For more details, see Tech-nical Support Note, TN-RNC-SW-146 in NOLS.

Steps

1 Configure the IP-based Iub in the RNC with the MML interface.g If NPGEP unit is used, all physical connections must be plugged in during creation

of IFGEx otherwise all the NPGEP units report a fault and NPGEP with any missing Ethernet connection restarts.

If VLAN is used:

a) Enable and check administrative status of IFGE0:ZQRN:NPGE,0:IFGE0:::::UP;ZQRI;

b) Create a VLAN interface to the NPGE-0 unit. The VLAN name is 'VL1', VLAN ID is 2 (VLAN ID can have value between 2 to 4094), the VLAN is attached to the physical interface IFGE0.ZQRM:NPGE,0:VL1:2:IFGE0;

c) Configure the IP address of the VLAN interface.ZQRN:NPGE,0:VL1:10.2.1.1,P:29:;g Pay attention to the IP address planning with the VLAN configuration at system

level. The sample IP addressing figures shown here depict the configuration with IP layer routing without the VLAN configuration option.

If VLAN is not used:d) Configure the IP address for the NPGE GE interface:

ZQRN:NPGE,0:IFGE0:10.2.1.1,:29:;ZQRI:NPGE,0:;

Proceed with the configuration for both cases:e) Configure the gateway for the NPGE to the external router:

ZQKC:NPGE,0:10.3.1.0,30:10.2.1.2:LOG;f) Create a DSPM (DSCP to PHB mapping) profile for the Ethernet interface (IFGE0):

Refer to the ZQ8B command in the MML manual.This is optional; also a default value can be used.

g) Assign a DSPM profile to an IP interface in the NPGE by using the given profile ID or the default profile ID:ZQ8S:NPGE,0:IFGE0:ENA::;

h) Check the internal IPoATM from the NPGE to ICSU:ZQMQ:ICSU,0::NPGE,0:::ALL;

i) Configure the Iub control plane subnet for ICSU units:ZQMN:1:10.1.1.0,26:;ZQML:;g The system configures the MTU for ICSU IP over ATM interface to value 1472

for the automatically generated internal full mesh IPoA. The ICSU Iub IPoA inter-

12 DN70481473Issue 02B


Id:0900d805807861b2


face MTU value should not be configured greater than 1472 in order to keep the SCTP layer fragmentation aligned with the BTS SCTP defragmentation func-tionality. If the MTU size on Iub is configured to be smaller than 1500, respec-tively the MTU size for ICSU unit has to be descreased (with the MML ZQRN command) to avoid fragmentation at NPGE.

j) Configure the IP based route to the IFGE0 for the Iub. Enter values for the bandwidth allocation according to the transport network dimensioning plan:ZQRU:ADD:1,"IUBWBTS1":8000:500:100:100:ON;ZQRC:NPGE,0:IFGE0:IPV4=10.2.1.1:ID=1:;or in case VLAN is used:ZQRC:NPGE,0:VL1:IPV4=10.2.1.1:ID=1:;

2 Configure the bidirectional forwarding detection (BFD) session to supervise the IP path to the BTS.

g BFD configuration is an optional step.a) Configure the BFD profile:

ZYGR:C:PROF=1,RXINT=500,TXINT=500,DMULT=2;b) Configure the BFD session between the RNC and BTS:

ZYGS:C:NPGE,0,1,10.2.1.1,10.3.1.1:PROF=1,ALARM=OFF;c) Set the BFD session state to enabled and the alarm state to on when the BTS is inte-

grated to the RNC:ZYGS:S:NPGE,0,1:ALARM=ON,MODE=0;

3 Configure DCN for the RNC.For instructions on configuring RNC (OMU) for data communication network (DCN), see Configuring IP stack in OMU in Configuring IP connection for RNC.

4 Configure the IP-based Iub in the RNC RNW Object Browser GUI.f The system configures the static IP route in ICSU towards Control Plane Destina-

tion Address Iub. When the IPNB object is disconnected from the WBTS, the static IP route is deleted based on its ROUTE NUMBER. Do not delete the static IP route manually, as it may cause a situation where the ROUTE NUMBER which might be used by other manually created IP routes, is removed while the IPNB object is dis-connected from the WBTS.

a) Open the RNC RNW Object Browser GUI.b) Create the IPNB object for the IP-based Iub control plane connections by selecting

Object h New h IP Iub h IPNB.1. Provide the IPNB with an object identifier.2. Give BTS CP/UP 10.3.1.1 IP address as a Control Plane Destination Address

Iub.3. The IP Based Route Identification value is retrieved from the WBTS object once

IPNB and WBTS are connected (when the IPNB ID is set in the WBTS and the corresponding IPNB exists in the system).

4. Configure minSCTPPort (Minimum SCTP port number). Make sure that the SCTP Port ID have a unique value.

DN70481473Issue 02B

5. In the D-NBAP List enter 1 for the Communication Control Port ID; the SCTP Port Number for D-NBAP is automatically calculated.

c) Create or modify the WBTS object so that it contains the IPNB reference and IP Iub user plane configuration.Ensure that the IPNB is selected, the IP Based Route ID is given, and the Iub Trans-port media selection is IP Iub.1. Configure IPNBId (IPNB object identifier) into the WBTS data.2. Set the attributes related to IP-based Iub user plane correctly.

Set IPBasedRouteIdIub so that it refers to the IP based route configured per MML ZQRU / ZQRC for the given BTS. In the example provided, value 1 is used.

In the IubTransportMedia (Iub Transport Media Selection) parameter, check IP Iub only.

The default values can be used for MinUDPPortIub, DSCPMedDCH, DSCPLow, DSCPHigh, DSCPMedHSPA, HSDPAULCToDSCP, HSUPADLCToDSCP, ToAWEOffsetNRTDCHIP, ToAWEOffsetRTDCHIP, ToAWSOffsetNRTDCHIP, and ToAWSOffsetRTDCHIP.

5 Configure the IP-based Iub in the Flexi WCDMA BTS.g Please note that depending on the BTS software release (WN6.0 or WN6.0 EP1),

the order of the steps might be different.

a) Open the BTS Site Manager.b) Start TRS Commissioning.

g The selection of the transport mode (ATM Iub/IP Iub/Dual Iub) can be made only in the BTS Site Manager Commissioning Wizard, not in the Flexi TRS Manager.

c) Enter the name and Id of the BTS. Enter the transport (TRS) and BTS IP address for DCN.

d) Set Transport Mode to Iub IP and take Ethernet interface (EIF) in use.e) Configure the Transport Ethernet Interface IP address (use example value

10.3.1.1/30). With WN6.0 EP1, when using VLANs, leave the IP address field empty and add new VLAN, configure the IP address, enter the Committed information rate and select Enable QoS checkbox.

f) Configure Quality of Service settings or use default values.g) With WN6.0 and earlier releases, if VLAN was configured in the RNC, take the VLAN

in use and assign a VLAN Id.h) Configure Far end SCTP subnet and ensure that the RNC ICSU IP is included in

the subnet.In the example provided, the ICSU control plane subnet in the RNC is 10.1.1.1/26.

i) Configure Minimum SCTP Port and Minimum UDP Port. The value of Minimum SCTP Port has to match the value set previously using RNC RNW Object Browser GUI.

j) Fill in the values according to transport network planning for the CAC Committed Bit Rate, Signalling Bit Rate, and DCN Bit Rate.In the example provided, these are: 2 Mbit for CAC Committed Bit Rate, 100 kbit for Signalling, and DCN Bit Rate.

k) Configure the BFD sessions to supervise the IP path to the RNC.

14 DN70481473Issue 02B

g The BFD configuration is an optional step. It requires BFD session established in the RNC as instructed in step Configure the bidirectional forwarding detection (BFD) session to supervise the IP path to the BTS.

l) Configure the synchronization source.m) Add the default gateway; ensure that the gateway is reachable given by the subnet

mask in the Transport Ethernet Interface.In the example provided, the external router default gateway is 10.3.1.2.

g A timing source is not automatically available for the IP Iub, and the synchronization source is provided by either a timing over packet master or Synchronous Ethernet. For more information, see Activating RAN1254: Timing over Packet for BTS Appli-cation SW and Activating RAN1708: BTS Synchronous Ethernet.

Expected outcomeThe RAN74: IP based Iub for Flexi WCDMA BTS feature has been activated, and after the IPNB object creation NBAP/SCTP terminations are created at the RNC.

3. Configure the BFD session to supervise the IP path to the RNC.g The BFD configuration is an optional step. It requires BFD session estab-

lished in the RNC as instructed in step Configure the bidirectional forwarding detection (BFD) session with the MML interface to supervise the IP path to the BTS.

To enable the BFD session, check In use and Active checkboxes in the Bidirec-tional Forwarding Detection section.Configure BFD-related parameters. BFD is a network protocol used to detect faults between two forwarding engines. It provides a low-overhead detection of faults even on physical media that do not support failure detection of any kind, such as Ethernet, virtual circuits, tunnels, and MPLS LSPs. BFD establishes a session between two endpoints over a particular link.Parameters that are set for establishing the BFD session are the following: Desired min. TX interval with the default value of 500 ms and the range

500-5000 ms in steps of 500 ms. Required min. RX interval with the default value of 500 ms and the range

500-5000 ms in steps of 500 ms. Detection multiplier with the default value of 5 and the range 2-10. Destination address (the IP address of the peer node that the BFD session

is to be established to).g Detection multiplier multiplied by the negotiated transmit interval, provides

the Detection Time for the transmitting system in Asynchronous mode.g Desired min. TX interval is the minimum interval, that the local system

would like to use when transmitting BFD control packets. The value zero is reserved.

g Required min. RX interval is the minimum interval, in microseconds, between received BFD Control packets that the system is capable of sup-porting. If the value is 0, the transmitting system does not expect the remote system to send any periodic BFD control packets.

Quality of Service - In the table you can modify queue weights. The rows in the table are always enabled and the weight is a mandatory parameter for each queue. AXC Manager proposes default values for weight parameters when a new A2UP is created. The possible values for the weight range from 1 to 1000 with 1 for the lowest priority and 1000 for the highest. Default values for weight parameters are the following: Q1: Strict queue, weight is not modifiable Q2: 1000 Q3: 500 Q4: 1

Default - With this button you set the default queue weight values in the Quality of Service table.g The Quality of Service table is visible only if:

AXCF is present and AXC is in the EUBB mode. AAL2 multiplexing is enabled, which is always true for EUBB in the ATM

Iub and Dual Iub mode. When EUBB is in the IP Iub mode, AAL2 multi-plexing is always disabled.

g You can delete a User Path by selecting the desired User Path and clicking Delete. You can modify a User Path by clicking Modify. While modifying the User Path you can modify only Performance Monitoring checkbox and QoS parameters.

f) Click Activate BTS settings to take the new settings in use. It is recommended to activate the settings only after you have configured both Iub terminations and BTS IP settings.

Expected outcomeFeature RAN1633: Dual Iub for UltraSite WCDMA BTS has been activated.

Further informationAAL2 signaling (STC alarm, Performance Monitoring and used WAMs with A2EA) and user paths (Performance monitoring) can be modified only when BTS AAL2 Multiplexing is enabled. NBAP terminations can not be modified at all.

g Note that deleting an Iub termination does not result in the deletion of Virtual Channel or Termination. As a consequence of deleting a signaling link, the related user paths are removed, while virtual channel and termination are not deleted.
