In this section:
The EMS uses the EMS CALEA user role for all LI configuration operations from and to the SBC Configurator, and the admin user role for communicating over netconf to the SBC. The EMS creates the SBC CALEA user credentials automatically when a SBC (including the SBC Configurator) registers to it. Cloud SBC instances are registered dynamically in the EMS.
A single CDC configuration is supported per cluster.
To configure CDC for cloud M-SBC instance:
To create basic configuration for M-SBC:
admin
user. Under Network Mgmnt, click Cluster / VNF Management. The Cluster/VNF Management window is displayed.
Create M-SBC cluster. For more information, refer to Creating an SBC SWe Cluster.
Click Configurations tab.
Click New Configuration. The New Configuration pane is displayed.
Select the version of the configuration from the Version drop-down.
Select an SBC Configurator instance from the Master Configurator drop-down.
This node is used to create the configuration. The SBC Configurator nodes are displayed based on the version selected. Only unlocked SBC Configurator nodes are listed.
Enter a name for the configuration in the Configuration Name field. The SBC configuration name can contain only letters, numbers, dashes (-), apostrophes ('), underscores (_), colons (:) and spaces.
The cluster ID is set as the default name for the first configuration. You can modify the name. The name must be unique.
The subsequent configurations are named with a combination of cluster name and some unique identifying information. The default name varies based on how the configuration is created.
Click Create. A circular progress bar is displayed against the Master Configurator node. It takes around six minutes to load master configuration.
When the Master Configurator node is loaded, the Open Editor button is displayed next to the Master Configurator node.
Click Open Editor. The SBC Configuration Manager window is displayed.
Click Apply Saved Changes and Close. A circular progress bar is displayed.
The configuration is saved on EMS SWe and the following window is displayed:
Create CDC configuration (Proceed to Configuring CDC using EMS CALEA User Account).
For LI, the CDC configuration is performed using the CDC Configuration Manager through EMS. You can Create CDC information only as EMS calea
user from the EMS CDC configuration window.
Prerequisites
Enable calea
user. For information, refer to Enabling Lawful Intercept on EMS Standalone.
Procedure
calea
user.Click Cluster CDC tab. The Cluster CDC pane is displayed.
Click Launch CDC Configuration Manager. The SBC Configuration Manager window is displayed.
Create Call Data Channel for M-SBC (Proceed to Creating Call Data Channel for M-SBC).
The SBC SWe provides the ability to configure the IP address, TCP port, and other parameters used for communication towards the mediation server.
To create a new Call Data Channel:
In the SBC Configuration Manager window, navigate to Configuration > Intercept > Call Data Channel. The Call Data Channel window is displayed.
Select default from Address Context drop-down menu.
Click New Call Data Channel. The Create New Call Data Channel window is displayed.
You can configure the LI using the default Address Context only.
Name: Type the name of the call data channel.
Intercept Standard: Select packetcable from the drop-down menu.
Vendor ID: Select ss8 from the drop-down menu.
Media IP Interface Group Name: Select media IP interface group name from the drop-down menu.
Click Save. The object is created successfully.
Click OK.
After the Call Data Channel is created, you must create Mediation Server objects associated with the Call Data Channel. The CDC configuration supports configuring up to eight Mediation Servers.
To create mediation server:
Navigate to Configuration > Intercept > Call Data Channel > Mediation Server. The Mediation Server window is displayed.
Select default from Address Context drop-down menu.
Select the Call Data Channel created for M-SBC from the drop-down menu.
Click New Mediation Server. The Create New Mediation Server window is displayed.
Type the mediation server name in Msname.
Click Save. The Object is created successfully.
Click OK. The Mediation Server List window is displayed. You can create up to eight mediation servers for M-SBC.
This screen includes the LI Mediation Server TCP Media intercept parameters.
To view TCP parameters:
Navigate to Configuration > Intercept > Call Data Channel > Mediation Server > Media > TCP. The TCP window is displayed.
Select default from the Address Context drop-down menu.
Select the Call Data Channel from the drop down menu.
Select the Mediation Server from the drop-down menu.
Configure the required details.
The configurations can only be updated with State as Disabled and Mode as Out Of Service.
Enable the mediation server by changing the State as Enabled and Mode as In Service.
Click Apply Saved Changes and Close.
Activate the CDC configuration (Proceed to Activating CDC Configuration for M-SBC).
To activate a cluster configuration for SBC SWe:
admin
user.Select the M-SBC cluster for which the CDC configuration is created.
Click Configuration tab. The Configuration pane is displayed.
Click Activate Configuration. The Activation in progress status is displayed. When the activation is completed, the nodes in the cluster are updated with the active configuration, the Configuration Status is displayed as Last update complete.
This object displays the mediation server media statistics.
To view the LI statistics:
Click Cluster CDC tab. The Cluster CDC pane is displayed.
Click View Nodes. The nodes list in the cluster is displayed.
Select the required node to view the mediation server media status.
Click Launch Node LI Stats. The Mediation Server Media Status window is displayed.
