1 Setting Up IM-SCF CAP Phase 1

This chapter describes how to set up an IM-SCF CAP Phase 1 interworking module.

About IM-SCF CAP Phase 1 Setup

The process of IM-SCF CAP phase 1 setup requires the following:

1. Adding an IM-SCF CAP phase 1 to your Oracle Communications Service Broker deployment. You can add as many modules of type IM-SCF CAP phase 1 as you need. See "Adding an IM-SCF CAP Phase 1 to the Service Broker Deployment" for more information.

2. Configuring the IM-SCF CAP phase 1. See "Configuring an IM-SCF CAP Phase 1" for more information.

Adding an IM-SCF CAP Phase 1 to the Service Broker Deployment

To add an IM-SCF CAP phase 1:

1. In the domain navigation pane, expand the OCSB node.

2. Expand the Processing Tier node.

3. Expand the Interworking Modules node.

4. Select IM Management.

5. On the bottom of the IM Management pane, click New.

6. In the New window, fill out the fields as follows:

   • In the Type list, select IMSCFCAP1.

   • In the Version list, select the required version.

   • In the Name field, enter a name for this module as it should appear in the list of modules. In this field, you can only use lower case letters (a-z), upper case letters (A-Z), numbers (0-9), and underscores (_). If you attempt to use a character which is not allowed, Service Broker displays the error message and prompts you to enter a different name.

7. Click OK.

8. In the notification window that reminds you to commit the changes, click OK.

9. To add the new IM-SCF CAP phase 1 to your deployment, in the Change Center pane, click Commit.

   An new module of type IM-SCF CAP phase 1 is now added to your Service Broker deployment. The new module is displayed in the domain navigation pane under the Interworking Modules node.

Configuring an IM-SCF CAP Phase 1

To configure an IM-SCF CAP phase 1:

1. In the Change Center, click Lock & Edit.

2. In the domain navigation pane, under the Interworking Modules node, select the newly added IM-SCF CAP phase 1.

Configuring General Parameters

The General subtab displays the protocol variant that is used to encode and decode SS7 messages and enables you to specify an alias for an IM instance.

Table 1-2 describes the configuration parameters on the General subtab.

Table 1-2 General Parameters

Name	Type	Description
Alias	STRING	Specifies an alias of the IM instance. Using this alias, the SS7 SSU recognizes the instances of the IMs to which incoming messages should be routed. For more information on how the SS7 SSU uses aliases and how to configure incoming routing in the SS7 SSU, see the discussion on configuring the SS7 Signaling Server Unit for SIGTRAN in Oracle Communications Service Broker Signaling Server Units Configuration Guide.
Plugin	STRING	Specifies the protocol variant used over the SS7 interface. It informs the IM which plug-in (class) to use to encode and decode SS7 messages.

Charging Services

You can configure IM-SCF to monitor session duration and charge sessions. IM-SCF provides the following capabilities:

• Credit reservation requests generation

  IM-SCF sends these requests to IM-OCF through the OE. IM-OCF translates credit reservation requests to Diameter CCRs, which are then forwarded to a billing application.

• Session monitoring and charging

  IM-SCF monitors and charges a session on its own.

• Quota reauthorization

  You can specify whether IM-SCF reauthorizes a quota upon receiving various triggers from an MSC.

To set up IM-SCF charging services, you use the Charging Services tab. This tab contains the subtabs described in Table 1-7.

Table 1-7 Charging Services Subtabs

Subtab	Description
General	Enables you to specify how IM-SCF sets up and sends credit reservation requests to the OE. See "General" for more information.
Reauthorization Triggers	Enables you to specify whether IM-SCF reauthorizes a quota upon receiving various triggers from an MSC. See "Reauthorization Triggers" for more information.

General

The General subtab enables you to specify how IM-SCF sets up and sends credit reservation requests to the OE. The OE forwards these requests to application-facing IMs as defined in the orchestration logic.
