CAMELPhase 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.

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.
