2. Overview
We will discuss the following topics:
• What Intelligent Networking is
• What are the principles of Intelligent Networking
• Where Intelligent Networking is defined today
• What services are defined for Intelligent Networking
• What the overall architecture is for an Intelligent
Network
3. What is Wireless Intelligent Networking?
An Evolving Network Architecture
Enhanced Mobile Services
New Capabilities
Intelligent Networking
Features Controlled Outside the Switch
Defined for Wireline and Wireless Networks
4. Intelligent Network Characteristics
It allows for rapid introduction of new
services
It is customer and telephone provider
programmable
It is supplier transparent and independent
It supports enhanced service provider access

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.

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);
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;

20. 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.
Editor's Notes
Chapter 5 shows how Phase 1 will modify existing ANSI-41 operations (Operation Specifiers) and parameters. Additionally, it defines new operations and parameters needed.
