Intelligent Networking Phases
CAMEL
CAMEL
Phase 1
Control of MO, MT and MF calls
Any time interrogation
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.
CAMEL
Phase 3
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.
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;

…the fundamental idea of the SS7 protocol is to divide
functions into MTP and various user parts...

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.
