9 Setting Up IM-SCF AIN 0.2

This chapter describes how to set up an IM-SCF AIN 0.2 interworking module.

About IM-SCF AIN 0.2 Setup

The process of IM-SCF AIN 0.2 setup requires the following:

Adding an IM-SCF AIN 0.2 to your Oracle Communications Service Controller deployment. You can add as many modules of type IM-SCF AIN 0.2 as you need. See "Adding an IM-SCF AIN 0.2 to the Service Controller Deployment" for more information.
Configuring the IM-SCF AIN 0.2. See "Configuring an IM-SCF AIN 0.2" for more information.

Adding an IM-SCF AIN 0.2 to the Service Controller Deployment

To add an IM-SCF AIN 0.2:

In the domain navigation pane, expand the OCSB node.
Expand the Processing Tier node.
Expand the Interworking Modules node.
Select IM Management.
On the bottom of the IM Management pane, click New.
In the New window, fill out the fields as follows:
- In the Type list, select IMSCFAIN02.
- 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 Controller displays the error message and prompts you to enter a different name.
Click OK.
In the notification window that reminds you to commit the changes, click OK.
To add the new IM-SCF AIN 0.2 to your deployment, in the Change Center pane, click Commit.

A new module of type IM-SCF AIN 0.2 is now added to your Service Controller deployment. The new module is displayed in the domain navigation pane under the Interworking Modules node.

Configuring an IM-SCF AIN 0.2

To configure an IM-SCF AIN 0.2:

In the Change Center, click Lock & Edit.

In the domain navigation pane, under the Interworking Modules node, select the newly added IM-SCF AIN 0.2.

The IM-SCF AIN 0.2 configuration screen contains the subtabs described in Table 9-1.

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 9-4.

Table 9-4 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.

Configuring Media Resources Parameters

The Media Resources subtab enables you to define the media resources that the SSP can connect in order to play announcements.

The table in the Media Resources subtab displays the media resources that are used to play announcements. Each row represents one media resource. When defining a new media resource, you need to specify the fields described in Table 9-8.

Table 9-8 IM-SCF AIN 0.2 Media Resource Definition Fields

Name	Type	Description
Name	STRING	Specifies a name of the media resource
Alias	STRING	Specifies a unique identifier that applications use to instruct IM-SCF which media resource to connect in order to play announcements. Alias is used by IM-SCF to lookup for media resource details in this table. Aliases are defined in a URI format. For example: mrf.network@domain.com.

Answer Indication	BOOL	Specifies whether a switch sends Answer message to the calling party upon connection to the media resource. Possible values: True Connection to the media resource causes the switch to generate answer indication towards the calling party. This opens a media path from the caller to the media resource (bothwayPathRequired) False The media path opens only in the direction from the media resource to the caller Default value: True

Configuring TCAP Parameters

The TCAP subtab enables you to set up parameters of the IM TCAP layer.

Table 9-9 describes configuration parameters on the TCAP subtab.

Table 9-9 TCAP Parameters

Reject Timeout in Seconds	INT	Specifies the time period in seconds that the IM waits for possible REJECT. The timer starts when sending INVOKE for class 1-3 operations.
Application Part Guard Timer	INT	Specifies the PSM timer, which is a timer for incoming operations. The PSM timer defines the maximum time in seconds that the application (TC-User) has to respond to incoming INVOKE messages.
Activate Invoke Alarm in Application Layer	BOOL	When the TCAP layer receives an INVOKE, it triggers back PABORT if there is no response. The waiting time period for response is configured in the encoding library. The Activate Invoke Alarm in Application Layer parameter specifies whether or not to activate this timer. Possible values: True False Default value: False.
Result Split Length	INT	Specifies the maximum length of the TCAP RESULT message. When the actual length of the message exceeds the specified value, the message is split.

Configuring Monitoring Parameters

The Monitoring tab enables you to define how Runtime MBeans and notifications operate for an IM-SCF.
