Interconnect Billing

Course Overview

This course is an UMTS System Overview with a bias towards radio planning and the ATM core network. As well as providing a comprehensive technical overview of UMTS functions, structure and operation, it covers transmission planning and traffic. ATM and other core are described in depth. There is a major section on UMTS planning.

There is a strong bias in the course towards delegates who are involved with radio cell, capacity and transmission planning. As UMTS is strongly based on GSM and GPRS, the course assumes a good familiarity with GSM and GPRS and their radio channels. No background in UMTS is assumed.

Skills Gained

The course will benefit delegates by providing an overall understanding of UMTS guidance of how transmission planning and traffic capacity for UMTS can be achieved a good understanding of the core network and ATM.
