2 OverviewCell broadcast service (CBS) provides a cell broadcast system that is supplemental to the existingdigital mobile communication platform. Through the cell broadcast system, the RNC sendsspecific short messages to cells in a designated area, and consequently the cells broadcast themessages to all the UEs supporting CBS within the coverage.The CBS provides the point-to-multipoint service for 3G network users.Messages broadcast using CBS are known as CBS messages. CBS-capable UEs constantly detectCBS messages and notify users of the messages received.The CBS has the following advantages:l Compared with the point-to-point service, the CBS enables multiple UEs to receive the

same message, saving system resources.l CBS service areas (SAs) map with physical cells in a one-on-one manner. This enables

CBS messages to be broadcast in designated areas.To meet the customers' requirements efficiently, Huawei employs two types of cell broadcastcenters (CBCs) to implement the CBS, namely, external CBC and built-in CBC.When the external CBC (WRFD-011000 Cell Broadcast Service) is used, it sends messages tothe RNC over the Iu-BC interface and then the RNC forwards the messages to UEs.When the built-in CBC (WRFD-011001 Simplified Cell Broadcast) is used, the RNC housingthe built-in CBC constructs messages and delivers them to UEs.Additionally, Huawei uses WRFD-020127 Warning of Disaster feature in built-in CBC scenario.Warning of Disaster is an enhancement to WRFD-011001 Simplified Cell Broadcast. In theabsence of an external CBC, Warning of Disaster enables Huawei RNCs to deliver warningnotifications to all users served by the RNCs as quickly as possible. The RNCs support initiating,modifying, and terminating warning notifications, and pre-designating target notification areas.Maintenance personnel manually trigger warning notifications on the LMT or U2000, which arethen sent to the RNCs.

3 Technical DescriptionThe external CBC and built-in CBC are used in different scenarios to meet different demandsof customers. They cannot be used at the same time. The warning of disaster function is supportedby only the built-in CBC.

WCDMA RANCBS Feature Parameter Description 3 Technical Description

3.1 External CBCThis section describes the system architecture, CBS message scheduling and forwarding,network topology with the Iu-BC interface configured, signaling protocols.

3.1.1 System ArchitectureThe CBC, as a part of the core network (CN), is connected to multiple RNCs through the Iu-BCinterface. The CBC manages the CBS messages, whereas the UMTS radio access network(UTRAN) performs transparent transmission of the CBS messages from the CBC.A common traffic channel (CTCH) needs to be configured for each cell supporting the CBSfeature. The CTCH is mapped onto a FACH.Figure 3-1 shows the system architecture when the external CBC is configured

Figure 3-1 System architecture when the external CBC is configured

CBC: cell broadcast center RNS: radio network subsystemSAC: service area code UTRAN: UMTS radio access network

In the release of RAN14.0, the second CBC can be configured as a redundancy CBC for thedisaster preventing.Figure 3-2 shows the system architecture when the second external CBC isconfigured.

Figure 3-2 System architecture when the second external CBC is configured

CBC: cell broadcast center RNS: radio network subsystemSAC: service area code UTRAN: UMTS radio access network

3.1.2 CBS Message Scheduling and ForwardingWhen the external CBC is used, the CBS implementation procedure is as follows:1. The external CBC sends a CBS message to the RNC over the Iu-BC interface. The message

contains service requirements such as the broadcast interval, broadcast times, and broadcastarea.

2. On receipt of the message, the RNC saves it to the buffer.3. The RNC schedules and forwards the message based on the CTCH bandwidth allocated to

the Uu interface and the service requirements.4. The UEs in CBS-capable cells receive CBS messages of the user-defined types.

UEs in idle mode or in the CELL_PCH or URA_PCH state can receive the CBS messages.5. The RNC deletes the CBS messages from the buffer.

3.1.3 Network Topology with the Iu-BC InterfaceThe external CBC supports only Iu-BC over IP. Therefore, switching from TCP/IP to IP overATM (IPoA) must be performed if the ATM transmission mode is used on the Iu-BC interface.Networking solutions are different in Iu-BC over IP mode and in Iu-BC over ATM mode.

Networking Solution in Iu-BC over IP ModeFigure 3-3 shows the networking solution in Iu-BC over IP mode.



6

Figure 3-3 Networking solution in Iu-BC over IP mode

CBE: cell broadcast entityRNS: radio network subsystem

The advantage and disadvantage of this networking solution are as follows:l Advantage

This networking solution provides flexible networking and simple configuration.l Disadvantage

If the IP addresses of the RNC and CBC are on different network segments, a route needsto be configured and extra routing devices need to be added. This leads to increase in thecost.

Networking Solution in Iu-BC over ATM ModeFigure 3-4 shows the networking solution in Iu-BC over ATM mode. In this mode, the ATMswitch implements the switching from the TCP/IP protocol stack to the IPoA protocol stack.



7

Figure 3-4 Networking solution in Iu-BC over ATM mode

The advantage and disadvantage of this networking solution are as follows:l Advantage

This solution is cost-effective because legacy ATM switches in the CN can be used and noadditional devices are required.Legacy ATM switches in the CN can be used, therefore requiring no additional devicesand reducing the costs.

l DisadvantageThere are potential risks that the CN equipment of other vendors does not inter-operatewith Huawei external CBC.

3.1.4 Signaling ProtocolsFigure 3-5 shows the protocol stack of CBS



8

Figure 3-5 CBS protocol stack

The signaling procedures exchanged between CBC and RNC are listed as follows:l Write-Replace procedure: used to broadcast new messages or replace the old messages.l Kill procedure: used to stop the broadcasting of specific messages in specific cells.l Load Status Inquiry procedure: CBC inquires the available bandwidth for message

broadcasting in specific cells.l Message Status Inquiry procedure: inquiry of the CBS message status (number of

transmitting specific messages in a cell)l Reset: stopping CBS service in specific cellsl Restart Indication: When cells resume and the CBS service is available again, the RNC

notifies the CN the cell status.l Failure Indication: The RNC notifies the CN that CBS service in a cell fails.For details, see 3GPP TS 23.041.

3.2 Built-in CBCThe CBC built in an RNC sends the cell name and messages to UEs on a regular basis. In additionto the basic CBS function, Huawei built-in CBC also provides a disaster warning function. Thebuilt-in CBC sends normal broadcast messages in normal situations and sends emergencybroadcast messages in emergencies.

3.2.1 System ArchitectureWhen the built-in CBC is used, maintenance personnel can manually trigger CBS messages onthe LMT or U2000, and the messages are then sent to the RNC over the OMCH. The RNC



9

broadcasts the received messages within designated cells. The messages can be broadcastperiodically.Figure 3-6 shows the system architecture when the built-in CBC is configured.

Figure 3-6 System architecture when the built-in CBC is configured

3.2.2 CBS Message Scheduling and ForwardingWhen the built-in CBC is used, the CBS implementation procedure is as follows:1. The RNC constructs CBS messages in the same way as the CBS server and saves the

messages to the buffer.2. The RNC schedules and forwards the messages based on the CTCH bandwidth allocated

to the Uu interface and the service requirements.3. The CBC forwards messages to UEs over the Uu interface. The UEs in CBS-capable cells

receive CBS messages of user-defined types. UEs in idle, CELL_PCH, or URA_PCH modecan receive CBS messages.

4. The RNC deletes the CBS messages from the buffer.

3.2.3 Message Construction in the RNCIn the built-in CBC case, the RNC needs to simulate functions of a CBS server by constructingCBS messages. The following messages need to be constructed:l Write-Replace message: This message is used to carry information. It is constructed and

sent by the RNC.l KILL message: When the CBS function is disabled and the function is deactivated in the

cell, the RNC needs to send a KILL message to the cell to stop the cell broadcasting CBSmessages.

The RNC does not need to send the Write-Replace response message or the KILL responsemessage to the CN.

3.2.4 Warning of DisasterThis section describes the feature WRFD-020127 Warning of Disaster.



10

The warning of disaster function is used to inform UEs in a designated area of disasters orbreaking events through broadcast. The purpose is to enable the subscribers to respond cautiouslyto emergencies.The warning of disaster function is supported by only the built-in CBC. When the function isapplied, the RNC constructs messages and delivers them to UEs in a designated area. Thedesignated area can be a single cell, multiple cells, or all cells under the RNC. The Warning ofDisaster feature does not require an external CBC.Areas can be designated on a per RNC, location area, or cell basis. For details, see section 5.3.3Feature DeploymentThe warning of disaster function enables the network operators to compose emergency messageson the O&M console when disasters (such as earthquake, tsunami, and hurricane) occur. Then,the O&M console requests the RNC to send the emergency messages to all the UEs in thedesignated area. The RNC sends the messages within four seconds after receiving the request.

5.1.7 Configuring CBS for a Cell at the Radio Network LayerThe CBS setup process consists of the following tasks:1. Setting up a CTCH2. Configuring the RLC for the CTCH3. Configuring the Broadcast/Multicast Control (BMC)4. Updating the system information on the Iub interface5. Sending the RESTART IND message on the Iu-BC interfaceWhen configuring CBS for a cell, ensure that the configurations of cell-level parameters in IPmode and ATM mode are consistent. Figure 5-1 shows the procedure for configuring CBS fora cell (at the radio network layer).



17

Figure 5-1 Procedure for configuring CBS for a cell

The procedure for configuring CBS for a cell is as follows:

Step 1 Run the RNC MML command ADD UCTCH to add the CTCH for the cell supporting CBS.NOTE

FACH ID is the unique identifier of an FACH in a cell. You need to negotiate the channel configurationscheme with NodeB engineers according to the channel specifications supported by the NodeB.

Step 2 Run the RNC MML command ADD UCELLCBSDRX to set the CBS DRX schedulingparameters for the cell supporting CBS.

NOTE

Generally, you can set the scheduling parameters to default values.

Step 3 Run the RNC MML command ADD UCELLCBSSAC to set the SAC that identifies the servicearea (SA) for the cell supporting CBS.

NOTE

You can add a specific CBS cell to the CBS SA by setting the cell ID (CELLID).CBS SAC identifies a CBS cell. The SAC is determined in network planning.CBS SAs are different from CS/PS SAs. CBS SAs have a one-on-one mapping with physical cells.CBS cannot be configured for two or more operators in a cell at the same time. In MOCN networks, it isrecommended that the CBS be configured for the primary operator or one of secondary operators.

Step 4 Run the RNC MML command ADD UCELLCBS to enable CBS in a cell. You can enable CBSonly after other radio network layer configurations are complete. After CBS is enabled, you can



18

monitor the RESTART IND message on the Iu-BC interface and the CBS scheduling messageon the Uu interface.----End

5.1.8 Verifying CBSStep 1 Check whether the CBS function works properly.

1. Ping the CBS IP address of the RNC on the CBC. If the ping operation is successful, itindicates that the data transmission from CBC to RNC is normal.

2. Ping the CBC IP address on the RNC. The source IP address is the device IP address, thatis, the IP address of the CBS. PING IP: SRN=0, SN=16, SIPADDR="12.12.12.12",DESTIP="11.11.11.11"; If the ping operation is successful, it indicates that the datatransmission from RNC to CBC is normal. If the ping operation fails, check theconfiguration.

3. Check whether the CBS socket is connected properly. To do this, trace messages over theIu interface and view whether the SABP_LOAD_QUERY is sent to the RNC, as shownin Figure 5-2

Figure 5-2 Viewing the SABP_LOAD_QUERY message

4. As shown in 5.1.8 Verifying CBS, the SABP_LOAD_QUERY_CMP message returnedfrom the RNC contains the information element (IE) available-bandwidth.

5.3 WRFD-020127 Warning of Disaster5.3.1 When to Use Warning of Disaster

In the absence of an external CBC, you are advised to use the Warning of Disaster feature tosend warning notifications about natural disasters (such as earthquakes and tsunamis) to mobileusers as quickly as possible. As an enhancement to WRFD-011001 Simplified Cell Broadcast,Warning of Disaster helps to better safeguard lives and property.

5.3.2 PlanningThe Warning of Disaster feature does not require an external CBC.

5.3.3 Feature DeploymentActivation

Before you activate Warning of Disaster, ensure that Simplified Cell Broadcast has beenactivated and the CBS is functioning normally in associated cells.To activate Warning of Disaster, perform the following steps:

Step 1 Activate the feature license.Step 2 Run the RNC MML command SET URNCCBPARA with CB Switch and CTCH switch of

cell broadcast both set to ON(ON).Step 3 Run the RNC MML command ADD UCBSAREA to set parameters for the designated

notification areas.Step 4 Run the RNC MML command ADD UCBSMSG to set parameters for cell broadcast messages.

----End

Activation ObservationTo verify whether the feature has been activated, use a test UE to camp on a designated cell, andcheck whether the test UE can receive CBS warning notifications.

5.4 Enabling UE Battery Saving for CBSAfter CBS is activated, UEs monitor the CTCH even when no CBS messages are sent, increasingbattery consumption of UEs. Two methods for UE battery saving were available, which aredescribed as follows:l Dynamically turning on/off the CTCH indicator

When no CBS messages are sent at the current scheduling moment, the CTCH indicator isturned off by default in system information block 5 (SIB5). The RNC sends the systeminformation to turn on the CTCH indicator if a CBS message is to be sent.The turned-on CTCH indicator will be turned off if no CBS messages are sent during acertain period.

l Dynamically adjusting the length of scheduling messagesIf no CBS messages are sent at the current scheduling moment, the RNC reduces the lengthof scheduling messages; if a CBS message is to be sent at the current scheduling moment,the RNC extends the length of scheduling messages.

NOTE

Using the methods for UE battery saving increases the transmission delay of CBS messages. It is goodpractice to disable UE battery saving for Warning of Disaster.

5.4.1 Dynamically Turning On/Off the CTCH IndicatorRun the RNC MML command ADD UCELLCBSDRX command withCTCH_DYN_CTRL_SWITCH selected in the CbsEnhanceSwitch parameter.

5.4.2 Dynamically Adjusting the Length of Scheduling MessagesStep 1 Run the RNC MML command DEA UCELLCBS to deactivate the CBS function for a cell.Step 2 Run the RNC MML command ADD UCELLCBSDRX with

CBS_SCHBLOCK_DYN_ADJ_SWITCH selected in the CbsEnhanceSwitch parameter.Step 3 Run the RNC MML command ACT UCELLCBS to activate the CBS function for a cell.
