  10. 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; Release 5 CAMEL Phase 4 Release 6 Release 7

  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.
