Description: Wireless Intelligent Network (WIN) covers the network capability that allows ANSI-41 wireless providers to create new services.  The standards that define the WIN architecture, call models, triggers and protocol are detailed.  This course also explains how the existing ANSI-41 standard is enhanced to make it more “intelligent”.  WIN is based on multiple standards that “add on” to existing mobility management standards.  All areas including Phase I, Pre-Paid Charging and Phase II are thoroughly explained.

Many exercises are provided throughout the course, reinforcing a practical understanding of the material.  This gives the student practice in analyzing the SS7 protocol and the ANSI-41 and WIN applications thus understanding how the data being sent and received is used.

What You Will Learn

The student will gain valuable knowledge of how mobile services are accomplished using WIN standards.  This includes how to analyze and decipher critical parameters within the SS7 protocol structure and the Mobile Application Part (MAP) application.  You will also learn important call flow scenarios of how network entities communicate vital information in a mobile network.  Additionally, you will learn major elements that make up WIN.  Also the relationship between the WIN call model and switch call processing will be explored.  This course will also examine the common protocols used and potential new and enhanced services.  There are many exercises provided that enhance the overall instruction.

Who Will Benefit From This Course

This course is designed for individuals responsible for or involved with network planning, switch maintenance, central office engineering, interconnection, technical support or network operations.  Though this course is designed for wireless providers, those involved in the wireline interconnect area might also find it beneficial.

Course Prerequisites

There are no prerequisites, though a basic understanding of mobile communications is helpful.
