- About Call Control Framework Integration
  MATRIXX Call Control Framework Integration provides information about MATRIXX Call Control Framework support and configuration.
- MATRIXX Call Control Framework
  MATRIXX includes an integrated GSM Service Control Function to support call control capabilities for telephony services.
  - Supported CAP Operations
    Call Control Framework (CCF) provides support for CAMEL Application Part (CAP) operations using the CAP1, CAP2, CAP3, and CAP4 protocols.
  - Supported Operations for VoiceXML
    Call Control Framework (CCF) provides support for CAP operations and the Capability Set 2 (CS2) for VoiceXML (VXML).
  - Voice Calls Using CAP4 Protocol
    Message sequences for voice calls using the CAMEL Application Part 2 (CAP2), CAP3, and CAP4 protocols are usually the same. However, CCF handles the following exceptions to message sequences for voice calls using the CAP4 protocol:
  - Time Zone Handling
    Call Control Framework (CCF) can handle dates and times in different time zones.
  - Transaction Overload Handling
    If the volume of voice and SMS traffic overloads the platform, Call Control Framework (CCF) throttles incoming voice and SMS transactions while continuing to process existing ones.
  - Network Request Processing
    Call Control Framework (CCF) can assign incoming requests to any processing server within a customer sub-domain.
  - MATRIXX Network Enabler
    The Network Enabler is a MATRIXX service that load balances TCAP messages across the processing servers, which offer charging and balance control operations. Each Network Enabler acts as a signaling gateway process (SGP) and the MATRIXX services on the processing servers act as application server processes (ASPs).
  - Network Enabler Fallback Processing
    Network Enabler performs fallback processing if it receives messages destined for a valid sub-domain but that sub-domain is down or unreachable, or if it fails to look up the sub-domain. If all sub-domains are down or unreachable, then MATRIXX Traffic Routing Agent (TRA) closes down all SCTP/IP links with SIGTRAN network clients.
- Supported Message Sequences
  MATRIXX Call Control Framework (CCF) provides support for message sequences using the Camel Application Part (CAP) protocol.
- Configuring MATRIXX Network Enabler
  This section describes how to configure MATRIXX Network Enabler.
- Configuring CAMEL Gateway
  CAMEL Gateway is a CAMEL Application Part (CAP) server. Configure CAMEL Gateway to allow communication between MATRIXX Engine and Network Enablers through the CAP protocols.
- Configuring Routing Preferences
  Configuring routing preferences allows you to define how routes are prioritized between CAMEL Gateway on each engine and Network Enablers.
- Configuring Correlation ID Length
  Call Control Framework (CCF) supports configurable correlation ID lengths. CCF handles 10 digit correlation ID lengths by default.
- Support for CAP1
  Call Control Framework (CCF) supports the processing of roaming voice calls that use the CAP1 protocol.
- Charging for CS1 INAP Calls
  Call Control Framework (CCF) provides support for processing and applying charging for voice calls that use the CS1 INAP protocol.
- Sending Furnish Charging Information
  You can configure Call Control Framework (CCF) to send Furnish Charging Information (FCI) operations at specific points during call handling. CCF sends FCI operations to instruct the Mobile Switching Center (MSC), or service switching point (SSF), to add charging information to the call data record (CDR) for a call.
- Support for MT Call Forwarding
  When handling a mobile terminating (MT) call, Call Control Framework (CCF) can forward the call to another number if the call is not answered, or the called number is busy.
- TCAP Handover and Relay Configuration
  Call Control Framework (CCF) can handover (relay) incoming TCAP requests for subscribers that MATRIXX cannot find in its subscriber database to another platform for processing. For example, when migrating to the MATRIXX platform, CCF can relay incoming TCAP requests to the incumbent platform for subscribers that have not yet been migrated across. After handover, the incumbent platform processes the TCAP request without any further involvement with MATRIXX.
- Support for Announcements
  MATRIXX Call Control Framework (CCF) provides support for playing pre-call announcements. The following topics describe CCF pre-call announcement functionality and explain how to configure CCF to play announcements.
- Support for USSD Services
  Call Control Framework (CCF) supports making Mobile Application Part (MAP) Unstructured Supplementary Service Data (USSD) call out requests to deliver USSD notifications to a subscriber. CCF also supports USSD services for queries, call back, and interactive menus using MAP-Process-UnstructuredSS-Request messages, and MAP-UnstructuredSS-Request messages.
- Announcements (IVR) and USSD Menus
  Call Control Framework (CCF) provides support for menu driven announcements using IVRs and interactive USSD service menus that give subscribers options for retrieving and updating their balances and account details.
- Apache FreeMarker Template Configuration
  You can configure Apache FreeMarker templates for handling Call Control Framework (CCF) services such as Unstructured Supplementary Service Data (USSD) query and call back services, and menu services using announcements or interactive USSD menus.
- Mobile Application Part (MAP) Call Outs
  MATRIXX Call Control Framework (CCF) provides support within the Charging Server for making MAP call out requests to an external platform in response to TCAP or Diameter messages that require them.
- Extending MAP Callouts
  You can extend the data used in Mobile Application Part (MAP) callout requests and results. You can include customized private extension data in the extensionContainer parameter in MAP ATI (AnyTimeInterrogation) and MAP SRI (SendRoutingInfo) operations. This feature enables you to manipulate the data sent and returned in MAP callouts, for example, to correct the digits dialed by a user when roaming.
- LDAP Callout Service
  Call Control Framework (CCF) provides support for making Lightweight Directory Access Protocol (LDAP) call out requests to an LDAP server in response to TCAP or Diameter messages that require them.
- Callout Response Data MDCs
  Call Control Framework (CCF) holds response data for Mobile Application Part (MAP) callouts and Lightweight Directory Access Protocol (LDAP) callouts for a call or a session in MATRIXX Data Container (MDC) format.

MATRIXX Call Control Framework

MATRIXX includes an integrated GSM Service Control Function to support call control capabilities for telephony services.

MATRIXX Call Control Framework (CCF) includes the following capabilities:

Direct connection to the Circuit Switched (CS) core network to enable charging and monitoring of voice calls and SMS MO without any dependency on third-party systems.
Support for multiple service patterns, such as the CAP2, CAP3, and CAP4 voice charging service patterns, and CAP3 SMS charging service pattern.
Support for charging for CAP1 and CS1 INAP calls using timers or the TSAN reorigination service.
Support for additional non-charge related Intelligent Network (IN) capabilities such as pre-call announcements, number translation, and number portability.
A flexible mechanism for controlling how to play pre-call announcements, including executing scripts implemented using VOICE XML (VXML) on an internal or an external IVR system.
Support for Unstructured Supplementary Service Data (USSD) notifications, queries, and call back services.
Support for interactive menus using IVR announcements or USSD.
Functionality for querying an external system, such as an HLR or an MNP database, using the MAP protocol.
Functionality for querying an LDAP server.

CCF enables service providers to replace their legacy IN Service Control Point (SCP) infrastructure with next-generation networks.

Note: When CCF is enabled, memory usage might increase by up to 552 MB.
