9 Creating Application Detection and Control Profiles

This chapter explains how to create Oracle Communications Service Broker Policy Controller (Policy Controller) Application Detection and Control (ADC) profiles that specify Quality of Service (QoS) limits and application redirection information for services.

This chapter assumes that you know the name of any predefined (PCEF-based) ADC rules that you must reference, including the ADC-Rule-Name AVPs to use.

About ADC Profiles

ADC profiles specify QoS limits and any application redirection information for service data flow traffic that your rules select. Your Policy Controller rules actually specify the application traffic that ADC profiles apply to. The ADC profile then applies QoS limits, and if redirection is used, the Web location to where the subscriber is redirected.

None of these options are required for a ADC profile to function; you can select the set of options that best suit your implementation.

ADC profiles can be either be dynamic (created within Policy Controller) or predefined (created and stored in your PECF).

ADC profiles are included in deployments along with your rulesets and PCC profiles. You can deploy, export, and re-import them as .rap files.

You use the Policy Designer Application Detection and Control Profile tab to manage ADC profiles.

Each ADC profile contains:

• Activation/deactivation dates and times that specify how long the ADC profile is in force.

• QoS limits, including:

  • A QoS Class Identifier (QCI) that specifies the type of traffic. There are nine specified options, or you can create your own.

  • The actual upper and lower bandwidth limits in bps, kpbs, Mbps, or Gbps.

  • An uplink status that controls whether uplink or downlink or both are allowed.

• Redirect Information, including:

  • The type of Web location (IPV4, IPV6, URL or SIP-URL)

  • The address to where the server subscribers are redirected.

  • A switch that turns the redirection options on and off.

You may also use any ADC profiles stored in your PCEF with the Policy Designer (predefined PCC rules). To use a predefined PCC rule in Policy Designer, simply create a new ADC profile with just the predefined PCC rule's name as it appears in the PCEF and select Predefined Profile from Apply Predefined Profiles/Apply Dynamic Profiles menu box. Predefined ADC profiles are marked with a check mark in the Predefined Profiles column of the Application Detection and Control Profiles tab.

Planning Your ADC Profiles

The procedures in the following section assumes that you already know the details of the ADC profiles to create, such as:

• The QoS limits to set.

• Redirection details including:

  • The internet protocol used by the redirection target.

  • The server address of the redirection target. If no address is specified, the default redirection set in the PCEF (if any) is used.

Creating an ADC Profile

To create an ADC Profile:

1. Start Policy Designer.

2. Navigate to Application Detection and Control Profiles.

3. Click Create.

   The ADC profile detail fields appear.

4. Enter a unique name for the ADC profile.

5. Select either Dynamic Profile or Predefined Profile from the dialog box.

6. Set a time limit for the ADC profile to be active:

   • To make the new ADC profile effective immediately and indefinitely, leave the Always Active check box checked.

   • To limit the ADC profile to a specific time period deselect the Always Active check box and enter start and stop dates and times:

     • Activation Time: Select the CEST time zone icon and select a time zone from the Select a Time Zone list. Then select the calendar/cloak icon to display the Select Date and Time date editor. Select a date and time for the ADC profile to activate. Click OK to make your choice take effect.

     • Deactivation Time: The time zone you set for the Activation Time is automatically also applied to the Deactivation Time. However, you can set a different time zone for Deactivation Time if your implementation requires it.

     Your activation and deactivation times can be set in different time zones

7. Specify the QoS parameters:

   1. QCI - QoS Class Identifier type as defined in the 3GPP TS 23.203 v9.90 (2011-06) standard. See the standard for details:

      http://www.3gpp.org/ftp/Specs/html-info/23203.htm

      Can be one of the default QCI values listed in Table 9-1, or any new ones that you create. Multiple QCI values can be used for the same services.

      Table 9-1 Default QCI Values

      QCI Value	Priority	Guaranteed Bit Rate?	Typical Service
      1	2	Yes	Conversational voice.
      2	4	Yes	Live video streaming.
      3	3	Yes	Real time gaming.
      4	5	Yes	Buffered video streaming.
      5	1	No	IMS Signalling.
      6	6	No	Buffered video streaming, TCP-based services (for example, email, chat, FTP, p2p file sharing, progressive video).
      7	7	No	Voice, live video streaming, interactive gaming.
      8	8	No	Buffered video streaming, TCP-based services (for example, email, chat, FTP, p2p file sharing, progressive video).
      9	9	No	Buffered video streaming, TCP-based services (for example, email, chat, FTP, p2p file sharing, progressive video).

      
      

   2. Gate Status - Specifies the PCEF action (gate open or closed) when service data flow traffic arrives from Policy Controller. Can be one of the following:

      • Uplink Enabled - Allows data uploading.

      • Downlink Enabled - Allows data downloading.

      • Both Enabled - Allows both data uploading and downloading.

      • Both Disabled - Disallows both data uploading and downloading.

      • Removed - This option is reserved for Oracle use.

   3. Set the Maximum Bandwidth options:

      • Maximum Bandwidth - Upload - Set a maximum upload data rate allowed by entering an integer in the dialog box and selecting a bit rate from the bit rate list.

      • Maximum Bandwidth - Download - Enter maximum download data rate allowed by entering an integer in the dialog box and selecting a bit rate from the bit rate list.

   4. Set the Guaranteed Bandwidth options:

      • Guaranteed Bandwidth - Upload - Set a minimum download data rate to use by entering an integer in the dialog box and selecting a bit rate from the bit rate list.

      • Guaranteed Bandwidth- Download - Enter a minimum download data rate to use by entering an integer in the dialog box and selecting a bit rate from the bit rate list.

8. Set the Redirection Information parameters:

   1. Select an internet protocol for the redirection target from the Type list.

   2. Enter the server IP address of the redirection target in the Server Address dialog box. If you do not specify an address, your PCEF uses it's own default redirection address.

   3. Select a setting from the Support list to enable/disable the redirection. The default blank setting does not send the redirection AVP (Redirect-Information); Redirection Enabled sends the redirection AVP, and Redirection Disabled sends the redirection AVP but instructs the PCEF to not redirect traffic for the profile.

   4. Click OK.

Changing the ADC Profile Table Display

You can change the list of ADC profiles columns or rearrange those columns using the View menu on the upper left of the Application Detection and Control Profiles tab.

To change the ADC profile display:

1. Start the Policy Designer.

2. Create ADC Profiles or import a deployment that includes ADC profiles.

3. Select an item from the View list:

   • The Columns item displays a list of all columns. Select or deselect individual columns to display/hide them.

   • The Reorder Columns item displays the Reorder Columns box. Select columns and move them up or down using the arrows on the right side of the box. Then click OK to make your changes take effect.

Filtering ADC Profiles by Text, Bandwidth, or Date

You can limit the list of ADC profiles displayed in the Application Detection and Control Profiles tab by entering parameters in the Filter field at the upper left side of the Policy and Charging Control tab.

At any time you can select the eraser icon to remove your filtering parameters and return to the default ADC profile display.

1. Start the Policy Designer.

2. Create ADC Profiles or import a deployment that includes ADC profiles.

3. Select Text, Bandwidth, or Date from the Filter list.

4. Enter parameters for the filter:

   • Text - As you type the list of ADC profiles is filtered by the text you enter.

   • Bandwidth - When you select Bandwidth, bandwidth dialog boxes appear. As you enter bandwidth limits, the list of ADC profiles is filtered by those parameters.

   • Date - When you select Date, the calendar/clock icons appear. As you select dates and times, the list of ADC profiles is filtered by the dates you choose.

Deleting ADC Profiles

You cannot delete an ADC profile until you have removed that profile from any rules that reference it. Ensure that the Profile/Rule Relationships column is empty for a ADC profile before you attempt to delete it. Hover your cursor over that column to find the names of rules that reference the ADC profile.

To delete an ADC profile:

1. Start Policy Designer.

2. (If necessary) Import the deployment containing the ADC profile to delete.

3. Navigate to the Application Detection and Control Profiles tab.

4. Ensure that the Profile/Rule Relationships column for the ADC profile is empty.

   You can hover your cursor over this table cell to find the names of the rules that reference the ADC profile. Remove any remaining rule references.

5. Select the ADC profile.

6. Click Delete.
