MAP Callout Service Configuration

Map Application Part (MAP) callout service configuration involves configuring:

  • The default MAP callout service and any other MAP call out services.
  • The Signaling Connection Control Part (SCCP) calling party address properties for MAP call out requests.
  • The Pricing component to define prerating queries for MAP services.
The MAP callout service requires that MATRIXX Call Control Framework is enabled in your system.

Service Configuration

MAP call out services are enabled by default. To enable MAP call out services if they are disabled, answer y to the following create_config.info question: Optional Feature:Do you want to enable MAP or LDAP call outs (y/n)?

During MATRIXX Engine configuration, system administrators can configure the following properties for the default MAP call out service, and any other MAP call out services:
  • The default timeout for responses to MAP call out requests.
  • The normalization rule sets to use for normalizing MAP callout results fields.
For information about configuring MAP call out service properties, see the discussion about how to configure MAP call out services.

SCCP Calling Party Address Configuration

System administrators can also configure, per processing pod, the following properties for the SCCP calling party address used in MAP call out requests:
  • The point code (pc) and global title (gt) values to use in the SCCP calling party address field in MAP call out requests.
  • The SCCP sub-system number to use.

If required, you can configure a separate SCCP calling party address per called global title. For example, you can set the calling global title to 4512345678 if the called global title starts with 45.

For information about configuring the SCCP address used in request messages for MAP callouts, see the discussion about how to configure the SCCP address for requests.

Pricing Configuration

During pricing configuration, pricing administrators define pre-rating queries for MAP callout services by configuring the following pre-rating data:
  • MAP callout actions — A pre-rating callout action defines MAP call out request properties for the following types of queries:
    • MAP-ATI and MAP-SRI requests to an external database, such as an Mobile Number Portability (MNP) database.
    • MAP-Interrogate-SS (supplementary service) requests to the Home Subscriber Server (HSS), for example, to retrieve the call forwarding status from the HSS for roaming VoLTE subscribers.
  • Data Modify Actions — A data modify action defines how to manipulate a field value in the MtxDiamRoMsg or MtxTcapMsg MDCs, or descendant of these MDCs, before the message is passed to rating. You can use a data modify action to:
    • Delete a field value in the destination MDC (MtxDiamRoMsg, MtxTcapMsg, or their descendants).
    • Replace a field value in the destination MDC with a constant.
    • Copy a field value from the source MDC (MtxDiamRoMsg, MtxTcapMsg, MtxSubscriberObject, or a descendant of these MDCs) to a field in the destination MDC.
  • Profiles — A pre-rating profile is a collection of pre-rating callout actions and data modify actions. Pre-rating actions can belong to more than one pre-rating profile.
  • Generators — A pre-rating generator defines the decision tables to use when determining the MAP callouts to perform. The results can be a pre-rating profile or a SKIP value.
  • The service type and service context to associate with each pre-rating generator.

For more information about pricing configuration for MAP call out services, see the discussion about PreRating query properties in My MATRIXX Help. For more information about data modify actions, see the discussion about data modify actions in My MATRIXX Help. For more information about PreRating, see the discussion about PreRating in My MATRIXX Help.

Information Query Flags

You select the information to query from the following options in the MAP callout action, Info Query Flags field:
  • Subscriber Location
  • Subscriber State
  • Subscriber IMEI
  • Service Info
  • Redirection Info
  • Routing Info
  • MNP Info
  • Interrogate Supplementary Service
  • Custom
A request for one or more types of information (like the subscriber location or state) is successful only if that information is returned in the response.

Custom MAP Callouts

Select the Custom flag if you are not looking for specific information. You can then use selective updates to customize the callout object after it is in the message. For more information, see the discussion about example MAP ATI call out extension configuration.
Note: Include only one custom query per PreRating profile. If multiple custom queries are attempted, only the result of the last query is stored. You cannot perform custom MAP-Interrogate-SS queries.
