		3.1.2  CBS Message Scheduling and Forwarding
			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 broadcast area.
			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 and the service requirements.
			4. The RNC deletes the CBS message from the buffer.

The warning of disaster function is used to inform UEs in a designated area of disasters or breaking
events through broadcast. The purpose is to enable the subscribers to respond cautiously to
emergencies.

The warning of disaster function is supported by only the built-in CBC. When the function is applied, the
RNC constructs messages and delivers them to UEs in a designated area. The designated area can be
a single cell, multiple cells, or all cells under the RNC.

The warning of disaster function enables the network operators to compose emergency messages on
the OM console when disasters (such as earthquake, tsunami, and hurricane) occur. Then, the OM
console requests the RNC to send the emergency messages to all the UEs in the designated area. The
RNC sends the messages within four seconds after receiving the request.

3.2.3 Message Construction in the RNC

In the built-in CBC case, the RNC needs to simulate functions of a CBS server by constructing CBS
messages. The following messages need to be constructed:

Write-Replace message: This message is used to carry information. It is constructed and sent by the
RNC.

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 CBS messages.

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

CBS 4 Engineering Guidelines

4 Engineering Guidelines

The following provides engineering guidelines regarding the configuration of CBS.

4.1 CBS Configuration in the Case of the External CBC

This section describes the CBS configuration procedure when the external CBC is used.

4.1.1 Activating the External CBC License

When the RNC uses the external CBC, the CBS license is required. To activate the CBS license,
perform the following steps:

1. Obtain a new license file.

2. Upload the license file to the BAM installation directory\FTP\license directory on the OMU by
using the FTP.

3. Run the ACT LICENSE command on the M2000 or RNC LMT to activate the license file.

4. Run the SET LICENSE command on RNC LMT to set the CBS license.

4.1.2 Configuring the Iu-BC Interface

To configure the Iu-BC interface, you must configure related data according to the actual network
topology.



The IP addresses on the Iu-BC interface can be shared. The device IP address of the Iu-BC interface board, however,
must be configured exclusively and cannot be shared.

4.1.3 Configuring CBS in Iu-BC over IP Mode

RNC Configuration

 Add an IP address of the Ethernet port.

Run the ADD ETHIP command to add the IP address of the Ethernet port.

The IP address of the Ethernet port connected to the CBC and the IP address of the CBC must be
on the same network segment.

 Add the device IP address of the interface board.

Run the ADD DEVIP command to add the device IP address of the interface board.

The IP address of the RNC interface board must be the same as the CBS IP address.

 Add the CBS configuration.

Run the ADD UCBSADDR command to add the TCP IP address used for the SOCKET
communication between the CBC and the RNC.

If the RNC IP address and the CBC IP address are on different network segments, configure the
related route before running the preceding command to ensure that the IP link works properly.

Router Configuration

For details, see the associated router configuration document. The data must be negotiated with the
RNC.

CBC Configuration

Configure the IP address of the CBC and the route from the CBC to the RNC.
