CAMEL
Phase 2
 Additional EDPs
 interaction between a user and a service using announcements, voice prompting and
information collection via in-band or USSD interaction;
 Control of call duration and transfer of AoC Information to the ms;
 The CSE can be informed about the invocation of the supplementary services ECT, CD
and MPTY;
 For easier post-processing, charging information from a serving node can be integrated in
normal call records.
 Support of facilities to avoid overload;
 Capabilities to support Dialed Services;
 Capabilities to handle mobility events, such as not-reachable and roaming;
 Control of GPRS sessions and PDP contexts;
 Control of mobile originating SMS through both CS and PS serving network entities;
 Interworking with SoLSA (Support of Localized Service Area) (optional)
 The CSE can be informed about the invocation of the SS CCBS.
CAMEL
Phase 3
 Control of MO, MT and MF calls
 Any time interrogation
 Support of Optimal Routing for CS mobile to mobile calls;
 Capability of the CSE to create additional parties in an existing call;
 Capability for the CSE to create a new call unrelated to any other existing call;
 Capabilities for the enhanced handling of call party connections;
 Capability for the CSE to control sessions in the IP Multimedia Subsystem (IMS);
 Enhanced CSE capability for dialed services;
 The capability to report basic service changes during ongoing call;
 The CSE capability to select between preferred and less preferred bearer services;
 The capability for the CSE to control trunk originated calls;
 The capability for the CSE to request additional dialed digits;

20. In Conclusion
• Wireless Intelligent Networking allows the service provider to rapidly
introduce new services
• Mobile Pre-Pay is a common application
• There are two overall standards employed today – CAMEL and WIN
• Maintaining and monitoring the Common Channel Signaling (CCS)
network is critical to its success
• Understanding and troubleshooting the SS7 protocol is a key part of
that success.
