In this section:

 

The EMS uses the EMS CALEA user role for all LI configuration operations from and to the SBC Configurator; admin user 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 the EMS. Cloud SBC instances are registered dynamically in the EMS.

A single CDC configuration is supported per cluster. The S-SBC does not support creation of a mediation server.

Prerequisites

To configure CDC for cloud S-SBC instance:

  • Instantiate EMS SWe instance with LI interface support using the EMS_SA_HEAT_TEMPLATE_<NAME> Heat Template. For more information, refer to "EMS Standalone Instantiation for Geographical Redundancy (GR) Deployment" topic in EMS documentation.
  • Create a Configurator cluster. For more information, refer to "Creating an SBC SWe Configurator Cluster' in EMS documentation.

  • Create a Configurator instance. For more information, refer to Instantiating SBC Configurator using Heat Template.

S-SBC Basic Configuration

To configure a basic S-SBC configuration, do the following:

  1. Log on to EMS as admin user.
  2. Under Network Mgmnt, click Cluster / VNF Management. The Cluster/VNF Management window is displayed.

  3. Create S-SBC cluster. For more information, refer to "Creating an SBC SWe Cluster" in EMS documentation .

  4. Click Configurations tab.

  5. Click New Configuration. The New Configuration pane is displayed.

    New Configuration

  6. Click Master Configurator tab.

  7. Select the version of the configuration from the Version drop-down.

  8. Select 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.

  9. 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.


  10. 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.

    Open Editor

  11. Click Open Editor. The SBC Configuration Manager window is displayed. 

    SBC Configuration Manager

  12. Create the basic S-SBC configuration on the SBC configurator. For information on S-SBC configuration, refer to "Creating an SBC SWe Cluster" topic in EMS documentation.

  13. Click Apply Saved Changes and Close. A circular progress bar is displayed.

    The configuration is saved on the EMS SWe and the following window displays:

    Locked Configurator

    .

  14. Create CDC configuration (Proceed to Configuring CDC using EMS CALEA User Account below).

Configuring CDC using EMS CALEA User Account

The LI Call Data Channel must be configured on  the S-SBC to indicate that it supports interception. For LI, the CDC configuration is performed using the CDC Configuration Manager through the 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" topic in EMS documentation.

Configure Cluster CDC for Cloud S-SBC nodes

To configure cluster CDC for cloud S-SBC nodes, accomplish the following:

  1. Log on to EMS as calea user.
  2. Under Network Mgmnt, click Lawful Intercept. The Lawful Intercept CDC Provisioning window is displayed.

  3. Click Cluster CDC tab. The Cluster CDC pane is displayed.

    Cluster CDC Tab


    The following parameters are displayed:

    Cluster Configuration Parameters

     ParameterDescription
    Locked ConfigurationSpecifies the configuration name.
    Configuration RoleSpecifies the type of the configuration role. The roles are Default and Alternate.
    ClusterSpecifies the name of the cluster.
    Master ConfiguratorSpecifies the name of the locked master configurator instance.

  4. Select S-SBC cluster with locked configurator node.

  5. Click Launch CDC Configuration Manager. The SBC Configuration Manager window is displayed. 

    Launch CDC Configuration Manager

  6. Create call data channel (Proceed to Creating Call Data Channel for S-SBC below).

Creating Call Data Channel for S-SBC

To create a new Call Data Channel:

  1. In the SBC Configuration Manager window, navigate to Configuration > Intercept > Call Data Channel. The Call Data Channel window is displayed.

    Call Data Channel for S-SBC

     You can configure the LI using the default Address Context only. 

  2. Select default from Address Context drop-down menu.

    Call Data Channel for M-SBC

  3. 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.

  4. Specify the following values:

    1. Name: Type the name of the call data channel.

    2. Intercept Standard: Select packetcable from the drop-down menu.

    3. Vendor ID: Select ss8 from the drop-down menu.

      Create CDC

      Call Data Channel Parameters

       ParameterDescription
      NameSpecifies the name of the CDC.
      Intercept StandardSpecifies the intercept standard used.
      Vendor IdSpecifies the vendor of the LI server used.

  5. Click Save. The object is created successfully.

  6. Click OK.

    Call Data Channel List

     

  7. Click Apply Saved Changes and Close.

  8.  Activate the CDC configuration (Proceed to Activating CDC Configuration for S-SBC below).

Activating CDC Configuration for S-SBC

To activate a cluster configuration for SBC SWe, accomplish the following:

  1. Log on to EMS as admin user.
  2. Under Network Mgmnt, click Cluster / VNF Management. The Cluster/VNF Management window is displayed.

  3. Select S-SBC cluster for which the CDC configuration is created. 

  4. Click Configuration tab.  The Configuration pane is displayed.

    Configuration Pane
