Intelligent Networking PhasesCAMEL

CAMEL

Phase 1

  • Control of MO, MT and MF calls
  • Any time interrogation
  • 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.

CAMEL

Phase 2

  • 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

  • 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;

in conclusion
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.
