Defining Sy Subscription ID Search Filters

You can configure multiple search filters per data source. For example, if a data source supports searching by MSISDN and IMSI, you can define multiple MSISDN and IMSI filters.
Note: Best practice recommends to priority order filtered data sources higher than unfiltered ones. See Ordering Data Source Priority for details on re-ordering data sources.
The APN search filter supports regular expressions and uses these patterns:
  • Wild Card: Pattern.*
  • Equal to: Pattern
  • Not Equal to: ^(?!.*Pattern).*$
These rules are followed when using the search filters:
  • If only subscription ID filters exist, if at least one subscription ID filter is matched, the result is matched.
  • If only APN filters exist, if at least one APN filter is matched, the result is matched.
  • If APN filters and subscription ID filters exist, if at least one subscription ID filter and one APN filter are matched, the result is matched.

To define search filters:

  1. Click the Search Filters tab.
  2. In the Subscription ID filters section of the window, click Add.

    The Add Search Key Value window opens.

  3. Select the Key Type from the list:
    • NAI

      Network address ID

    • E.164 (MSISDN)

      Phone number

    • IMSI

      International Mobile Subscriber Identity

    • Alternate Filter

      If the Sy data source is a secondary data source, the Alternate Filter specifies a subscriber profile attribute retrieved from the primary data source lookup process. For example, if the primary data source returned a subscriber profile attribute named PaymentPlan with a value of either Prepaid or Postpaid, you could configure an alternate filter, PaymentPlan, to direct Sy lookup procedures for Prepaid subscribers to one data source and Postpaid subscribers to a different data source.

  4. Enter a regular Expression.
    For example:
    • 508.*

      Matches numbers beginning with 508

    • ".*@example.com"

      Matches strings ending with @example.com

    • .*

      Matches any input string

  5. Click Save.

    The expression displays in the list of Filters in the Subscription ID filters section of the window.

  6. Click Save to save your changes or proceed with Selecting Sy Associated Data Sources (optional).
