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.
CAMELPhase 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;

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.
