Rf-Optimization AND Log-File Analysis

INTRODUCTION

Every alive Network needs to be under continues control to maintain/improve the

performance. Optimization is basically the only way to keep track of the network by

Wcdma Channels ( Detailed ) CHAPTER ONE/THREE

WCDMA Channels

Logical Channels are not actually channels but rather they can be defined as different tasks performed by the network and the UE at different times.They describe the type of information to be transferred.
Logical channels are categorized into control channels and traffic channels.Control channels carry the control plane information.Traffic Channels carry the user plane information.
Transport channels describes how the logical channels will be transferred, or it can be defined as how and with what characteristics data is transferred over the interface.
It comes into two groups:
·       Dedicated Channels
·       Common Channels

TRANSMISSION SYSTEMS

Introduction To Transmission Systems
•        Transmission systems form the backbone of any networks.
•        Normally transmission systems include SDH, PDH, ATM, Microwaves, leased lines.
•        In GSM normally the core network is located in the same premises and are mostly interconnected by fixed wireline. In huge network consisting of many MSC located at different places the interconnection may be through any of the transmission systems mentioned above.
•        The Access network consists of BSC’s with many BTS’s connected to them in various transmission topologies. Normal practice is to connect various BSC’c to the MSC via fiber and different BTS’s connected to BSC via microwave in Daisy chain, star or any other topology. However there can be many different ways of implementation.

COMMUNICATION PROCESS

•        Each layer has its own specified functions and provides specific services for the layers above
•        It is important to define the interfaces between different layers and the functions within each layer.
•        The way a function is realized within a layer is not predicted.
•        Logically, the communication between functions always takes place on the same level according to the protocols for that level.
