Characters of Inter-Frequency Handover:-

·       The carrier frequency of the current cell and target cell are different

·       Based on the triggering causes of handover

Inter-frequency handover can be categorized into four types:-

ü  Coverage-based

ü  QoS-based

ü  Load-based

ü  Speed-based

WCDMA ( 3G ) Channels "Detailed" Chapter Two/Three

WCDMA ( 3G ) Channels

Channel Mapping

·       The data can be sent through logical layer via different channels in the transport layer.
·       And also one transport channel can be sent via different physical channels.
·       These selection of channels in the transport and physical layer depends on the data itself and radio resource management and its parameters.

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
