Intelligent Networking Phases CAMEL Phase 1 ü Control of MO, MT and MF calls ü Any time interrogation CAMEL Phase 2 ü Additional EDPs ü interaction between a user and a service using announcements, voice prompting and information collection via in-band or USSD interaction; ü Control of call duration and transfer of Ao. C Information to the ms; ü The CSE can be informed about the invocation of the supplementary services ECT, CD and MPTY; ü For easier post-processing, charging information from a serving node can be integrated in normal call records. CAMEL Phase 3 ü ü ü ü 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 So. LSA (Support of Localized Service Area) (optional) The CSE can be informed about the invocation of the SS CCBS. ü ü ü ü ü 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
