2.16.2 Reference CAF Applications

DSR delivers the following reference CAF applications which can be used by customers:

• Steering of Roaming (SoR): The SoR application lets home network operators control and distribute registration traffic of their outbound roamers. Use SoR to define static distribution roaming steering policies for each group of roaming partners that are part of the same country. Refer SoR User's Guide for more details.
• Zero Balance Application (ZBA): When a mobile data service subscriber initiates a data session, a network Element (PCEF or CTF) may attempt to setup a data session for the subscriber and query the OCS for service units. In the case where the subscriber has no credit in their account, the OCS will rejectthe request, usually with an indication that the subscriber has no credit. However, in most cases the PCEF, or other CTFs (Charging Trigger Functions), will continue to attempt to query the OCS. This can create overload on the OCS to handle requests for subscribers that will always be denied during the period in which the subscriber has no credit. The purpose of the ZBA application is to detect when a subscriber, identified by a MSISDN, has a zero balance in his/her account, the ZBA application under certain configurable conditions, may respond on behalf of the OCS and reduce the number of queries the OCS must handle for subscribers who temporarily have no credit. Refer Zero Balance Application User's Guide for more details.
