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.

CAMEL

Phase 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);

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.
