Configuring Local Profile Selection

During the authorization process, SBR Carrier uses user-defined profile selection rule sets to select the local profile used to authorize the request. To select the correct profile for authorization, the server compares the HSS or downstream server response with the profile selection rule sets in the order in which they are defined. A match is declared when everything in a profile selection rule set is included in the HSS or downstream server response. If a match is found, the local profile associated with the profile selection rule set is merged with the HSS or downstream server response to form a complete profile which is used to authorize subscriber’s requests.

The merged profile is cached in SBR Carrier and used to authorize all future requests from the subscriber. The cached profile in SBR Carrier and the HSS are synchronized through the Push Profile Request (PPR) process, which notifies the SBR Carrier server about the profile modification through a PPR message. If there is a conflict between the two databases, the HSS profile data takes precedence over the SBR Carrier profile data.

A specific profile can be configured for processing requests with no matching rules, or you can configure the server to reject all requests for which no match is found.

SBR Carrier can also provide backup support for the HSS by continuing to process requests when the HSS is unavailable. A specific profile can be defined for processing requests in this situation, or you have the option to reject all requests when the HSS is unavailable.

Note: SBR carrier selects the local profile based on the individual AVPs and not based on the AVPs within the grouped AVPs.

To configure the local profile selection using the Web GUI:

  1. Select Diameter Configuration > Policy > Local Profile Selection.

    The Local Profile Selection page (Figure 171) appears.

Selection Page
  2. Configure a local profiles selection rule set. For more information about configuring a profile selection rule set, see Creating a New Profile Selection Rule Set, Editing Profile Selection Rule Sets, and Deleting Profile Selection Rule Sets.
  3. Define the order of the rule sets by selecting each rule set and using the Up or Down arrow.
  4. Specify whether to reject all requests or use a specific profile when there is no match found during the profile selection process in the When No Ruleset Matches area.
    • Select the Reject All option to reject all requests that do not have a matching rule.
    • Select the Use Selected Profile option and select a profile that you want to use for requests that do not have a matching rule.
  5. Specify whether to reject all requests or use a specific profile to continue to process the authorization requests when HSS is unavailable. In the When HSS is Not Available area, you can:
    • Select the Reject All option to reject all requests when HSS is unavailable.
    • Select the Use Selected Profile option and select a profile that you want to use for all requests when HSS is unavailable.
  6. Click Save to save the configuration.

Creating a New Profile Selection Rule Set

A profile selection rule set consists of ordered lists of user-defined attributes and/or non-3GPP interworking policies. To create a profile selection rule set, first you select the profile for which you want to create the selection rule set. You then add the user-defined attributes and non-3GPP interworking policies.

To create a profile selection rule set using the Web GUI:

  1. In the Local Profile Selection page (Figure 171), click Add.

    The Add Profile Matching Ruleset dialog box (Figure 172) appears.

    Figure 172: Add Profile Matching Ruleset Dialog

  2. Select the profile for which you want to create the profile selection rule set from the Profile list.
  3. Create matching rules for the selected profile. For more information about creating matching rules, see Creating New Matching Rules.

    Each row represents a rule. A rule can contain one or more attributes. You can modify the matching rules by using the Edit and Delete buttons.

  4. Click OK to save the configuration.

    The Local Profile Selection page (Figure 171) displays an updated list of local profiles selection rule sets.

Creating New Matching Rules

To create new matching rules using the Web GUI:

  1. In the Add Profile Matching Ruleset dialog box (Figure 172), click Add.

    The Add Profile Matching Rule dialog box (Figure 173) appears.

  2. From the Add Profile Matching Rule dialog box, you can:

Configuring User Defined Attribute Matching Rules

To configure user defined attribute matching rules using the Web GUI:

  1. In the Add Profile Matching Rule dialog box (Figure 173), select the User Defined Attributes option.

    The Match these AVPs from response pane (Figure 174) appears.

  2. Click Add.

    The Add AVP dialog box (Figure 175) appears.

  4. Enter a value for the selected attribute in the Value field and click Add.
  5. Repeat steps 3 and 4 to assign more attributes to the matching rule.
  6. When you are finished adding attributes, click Cancel. The Match these AVPs from response pane (Figure 174) displays the updated list of attributes. You can modify the matching rule attributes list by using the Edit and Delete buttons.
  7. Click OK.

    The Add Profile Matching Ruleset dialog box (Figure 172) displays the updated matching rule list.

Editing Profile Selection Rule Sets

To edit the existing profile selection rule set using the Web GUI:

  1. Select Diameter Configuration > Policy > Local Profile Selection.

    The Local Profile Selection page (Figure 171) appears.

  2. Select the profile selection rule set entry that you want to edit.
  3. Click Edit.

    The Edit Profile Matching Ruleset dialog box (Figure 177) appears.

  4. Change the profile for which you want to add or edit the profile selection rule set from the Profile list.
  5. In the Rules area, you can:
    • Click Add to add a new matching rule for the selected profile. The Add Profile Matching Rule dialog box (Figure 173) appears. For more information about creating new matching rules, see Creating New Matching Rules.
    • Select a matching rule entry and click Edit to edit the existing rule. For more information about the fields in the Edit Profile Matching Rule dialog box, see Creating New Matching Rules.
